Chapter 2.1 - Windows Programming

Unit-2: Application Development using C#.
NET
Windows Programming
Microsoft Windows is an operating system that provides graphical objects used by people to
interact with a computer. These objects, called windows, must be primarily created by a person or
a company, then installed on a computer that will be used. To create one of these objects, you can
use a computer language such as C++, Java, Object Pascal, Assembly, C#, etc.
Windows Forms
Windows Forms is a technique of creating computer applications based on the common language
runtime (CLR). It offers a series of objects called Windows Controls or simply, controls. These
controls are already created in the .NET Framework through various classes. Application
programming consists of taking advantage of these controls and customizing them for a particular
application. To exploit these controls and other features of the .NET Framework, there are
various types of applications you can create, including graphical applications (windows), web-
based applications (ASP.NET web applications), or console applications, etc.
There are two broad categories of objects used in a Windows Forms application: the forms and
the controls. The objects used in a Windows Forms application are stored in libraries also called
assemblies. As normal libraries, these assemblies have the extension .dll (which stands for
dynamic link library). In order to use one of these objects, you must know the name of the
assembly in which it is stored. Then you must add a reference to that assembly in your
application.
Create a project
First, you'll create a C# application project. The project type comes with all the template files
you'll need, before you've even added anything.
1. Open Visual Studio 2010 / 2015 / 2015 / 2017 or 2019.

2. On the start window, choose Create a new project.
3. The next step is to choose the project type as a Windows Forms application. Here we also
need to mention the name and location of our project.

Unit-2: Application Development using C#.NET
1. In the project dialog box, we can see various options for creating different types of
projects in Visual Studio. Click the Windows option on the left-hand side.
2. When we click the Windows options in the previous step, we will be able to see an option
for Windows Forms Application. Click this option.
3. We then give a name for the application which in our case is DemoApplication. We also
need to provide a location to store our application.
4. Finally, we click the 'OK' button to let Visual Studio create our project.
If the above steps are followed, you will get the below output in Visual Studio.
Create the application
Add a button to the form
1. Choose Toolbox to open the Toolbox fly-out window.

2
(If you don't see the Toolbox fly-out option, you can open it from the menu bar. To do
so, View > Toolbox. Or, press Ctrl+Alt+X.)
2. Choose the Pin icon to dock the Toolbox window.
3. Choose the Button control and then drag it onto the form.
4. In the Properties window, locate Text, change the name from Button1 to Click this, and

then press Enter.

3
(If you don't see the Properties window, you can open it from the menu bar. To do so,
choose View > Properties Window. Or, press F4.)
5. In the Design section of the Properties window, change the name

from Button1 to btnClickThis, and then press Enter.
Note
If you've alphabetized the list in the Properties window, Button1 appears in

the (DataBindings) section, instead.
Add a label to the form
Now that we've added a button control to create an action, let's add a label control to send text to.
1. Select the Label control from the Toolbox window, and then drag it onto the form and
drop it beneath the Click this button.
2. In either the Design section or the (DataBindings) section of the Properties window,
change the name of Label1 to lblHelloWorld, and then press Enter.

4
Add code to the form
1. In the Form1.cs [Design] window, double-click the Click this button to open

the Form1.cs window.
(Alternatively, you can expand Form1.cs in Solution Explorer, and then choose Form1.)
2. In the Form1.cs window, after the private void line, type or enter lblHelloWorld.Text

= "Hello World!"; as shown in the following screenshot:
Run the application
1. Choose the Start button to run the application.
Several things will happen. In the Visual Studio IDE, the Diagnostics Tools window will
open, and an Output window will open, too. But outside of the IDE, a Form1 dialog box
appears. It will include your Click this button and text that says Label1.
2. Choose the Click this button in the Form1 dialog box. Notice that the Label1 text changes

to Hello World!.

5
3. Close the Form1 dialog box to stop running the app.

Working with Toolbox Controls

Button in C#
A Button is an essential part of an application, or software, or webpage. It allows the user to
interact with the application or software. For example, if a user wants to exit from the current
application so, he/she click the exit button which closes the application. It can be used to perform
many actions like to submit, upload, download, etc. according to the requirement of your
program. It can be available with different shape, size, color, etc. and you can reuse them in
different applications. In .NET Framework, Button class is used to represent windows button
control and it is inherited from ButtonBase class. It is defined
under System.Windows.Forms namespace.
In C# you can create a button on the windows form by using two different ways:
1. Design-Time: It is the easiest method to create a button. Use the below steps:
 Step 1: Create a windows form as shown in the below image:

Visual Studio -> File -> New -> Project -> WindowsFormApp
 Step 2: Drag the Button control from the ToolBox and drop it on the windows form. You
are allowed to place a Button control anywhere on the windows form according to your
need.

7
 Step 3: After drag and drop you will go to the properties of the Button control to set the
properties of the Button.
2. Run-Time: It is a little bit trickier than the above method. In this method, you can create your
own Button using the Button class.
Step 1: Create a button using the Button() constructor is provided by the Button class.
// Creating Button using Button class

Button MyButton = new Button();
Step 2: After creating Button, set the properties of the Button provided by the Button class.
// Set the location of the button
Mybutton.Location = new Point(225, 198);
// Set text inside the button

Mybutton.Text = "Submit";
// Set the AutoSize property of the button

Mybutton.AutoSize = true;
// Set the background color of the button

Mybutton.BackColor = Color.LightBlue;
// Set the padding of the button

Mybutton.Padding = new Padding(6);
// Set font of the text present in the button

Mybutton.Font = new Font("French Script MT", 18);
Step 3: And last add this button control to form using Add() method.

8
// Add this Button to form

this.Controls.Add(Mybutton);
Example:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace WindowsFormsApp8 {
public partial class Form1 : Form {
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)

{
// Creating and setting the properties of label

Label l = new Label();
l.AutoSize = true;
l.Text = "Do you want to submit this project?";
l.Location = new Point(222, 145);
l.Font = new Font("French Script MT", 18);
// Adding this label to form
this.Controls.Add(l);
// Creating and setting the properties of Button

Button Mybutton = new Button();
Mybutton.Location = new Point(225, 198);
Mybutton.Text = "Submit";
Mybutton.AutoSize = true;
Mybutton.BackColor = Color.LightBlue;
Mybutton.Padding = new Padding(6);
Mybutton.Font = new Font("French Script MT", 18);
// Adding this button to form

this.Controls.Add(Mybutton);
// Creating and setting the properties of Button

Button Mybutton1 = new Button();
Mybutton1.Location = new Point(360, 198);
Mybutton1.Text = "Cancel";
Mybutton1.AutoSize = true;
Mybutton1.BackColor = Color.LightPink;

9
Mybutton1.Padding = new Padding(6);

Mybutton1.Font = new Font("French Script MT", 18);
// Adding this button to form

this.Controls.Add(Mybutton1);
}
}
}
Output:

CheckBox in C#
The CheckBox control is the part of windows form which is used to take input from the user. Or
in other words, CheckBox control allows us to select single or multiple elements from the given
list or it can provide us options like yes or no, true or false, etc. It can be displayed as an image or
text or both. The CheckBox is a class and defined under System.Windows.Forms namespace. In
Windows form, you can create CheckBox in two different ways:
1. Design-Time: It is the simplest way to create a CheckBox using the following steps:
Step 1: Create a windows form as shown in the below image:

Step 2: Drag the CheckBox control from the ToolBox and drop it on the windows form. You
can place CheckBox anywhere on the windows form according to your need.

11
Step 3: After drag and drop you will go to the properties of the CheckBox control to modify the
CheckBox design according to your requirement.
Output:
2. Run-Time: It is a little bit trickier than the above method. In this method, you can create your
own checkbox programmatically using the CheckBox class.
Step 1: Create a checkbox using the CheckBox() constructor provided by the CheckBox class.
// Creating checkbox
CheckBox Mycheckbox = new CheckBox();
Step 2: After creating CheckBox, set the properties of the CheckBox provided by the
CheckBox class.
// Set height of the checkbox

12
Mycheckbox.Height = 50;
// Set width of the checkbox

Mycheckbox.Width = 100;
// Set location of the checkbox

Mycheckbox.Location = new Point(229, 136);
// Set text in the checkbox

Mycheckbox.Text = "Married";
// Set font of the checkbox

Mycheckbox.Font = new Font("Bradley Hand ITC", 12);
Step 3 : And last add this checkbox control to form using Add() method.
// Add this checkbox to form
this.Controls.Add(Mycheckbox);
Example:
using System;
using System.Data;
using System.Linq;
using System.Text;
public Form1()
{
}

{
l.Text = "Select Status:";
l.AutoSize = true;
l.Font = new Font("Bradley Hand ITC", 12);
// Adding lable to form
// Creating and setting the properties of CheckBox

CheckBox Mycheckbox = new CheckBox();
Mycheckbox.Height = 50;
Mycheckbox.Width = 100;
Mycheckbox.Location = new Point(229, 136);
Mycheckbox.Text = "Married";
Mycheckbox.Font = new Font("Bradley Hand ITC", 12);

13
// Adding checkbox to form

this.Controls.Add(Mycheckbox);
// Creating and setting the properties of CheckBox

CheckBox Mycheckbox1 = new CheckBox();
Mycheckbox1.Location = new Point(230, 198);
Mycheckbox1.Text = "UnMarried";
Mycheckbox1.AutoSize = true;
Mycheckbox1.Font = new Font("Bradley Hand ITC", 12);
// Adding checkbox to form

this.Controls.Add(Mycheckbox1);
}
}
}

ComboBox in C#
In Windows Forms, ComboBox provides two different features in a single control, it
means ComboBox works as both TextBox and ListBox. In ComboBox, only one item
is displayed at a time and the rest of the items are present in the drop-down menu.
The ComboBox is a class in C# and defined
under System.Windows.Forms Namespace. You can create ComboBox using the
two different ways:
1. Design-Time: It is the easiest method to create a ComboBox control using the
following steps:
 Step 2: Drag the ComboBox control from the ToolBox and drop it on the windows
form. You are allowed to place a ComboBox control anywhere on the windows form
according to your need.

15
 Step 3: After drag and drop you will go to the properties of the ComboBox control to
set the properties of the ComboBox according to your need.
Output:
Run-Time: It is a little bit trickier than the above method. In this method, you can set
create your own ComboBox control using the ComboBox class. Steps to create a
dynamic ComboBox:
Step 1: Create a combobox using the ComboBox() constructor is provided by the
ComboBox class.
// Creating combobox using ComboBox class
ComboBox mybox = new ComboBox();
Step 2: After creating ComboBox, set the properties of the ComboBox provided by the
ComboBox class.
// Set the location of the ComboBox
mybox.Location = new Point(327, 77);
// Set the size of the ComboBox

mybox.Size = new Size(216, 26);

16
// Add items in the ComboBox

mybox.Items.Add("C#");
mybox.Items.Add("Java");
mybox.Items.Add("Scala");
mybox.Items.Add("C");
mybox.Items.Add("C++");
Step 3: And last add this ComboBox control to form using Add() method.
// Add this ComboBox to the form
this.Controls.Add(mybox);
Example:
using System;
using System.Data;
using System.Linq;
using System.Text;
public Form1()
{
}

{
l.AutoSize = true;
l.Text = "Select Programming Language";
// Adding this label to the form

// Creating and setting the properties of comboBox

ComboBox mybox = new ComboBox();
mybox.Location = new Point(327, 77);
mybox.Size = new Size(216, 26);
mybox.Items.Add("C#");
mybox.Items.Add("Java");
mybox.Items.Add("Scala");
mybox.Items.Add("C");
mybox.Items.Add("C++");
// Adding this ComboBox to the form

this.Controls.Add(mybox);

17
}
}
}
Output:
Label in C#
In Windows Forms, Label control is used to display text on the form and it does not
take part in user input or in mouse or keyboard events. The Label is a class and it is
defined under System.Windows.Forms namespace. In windows form, you can create
Label in two different ways:
1. Design-Time: It is the easiest method to create a Label control using the following
steps:
 Step 2: Drag the Label control from the ToolBox and drop it on the windows form. You
are allowed to place a Label control anywhere on the windows form according to your

18
need.
 Step 3: After drag and drop you will go to the properties of the Label control to set the
properties of the Label according to your need.
Output:

19
2. Run-Time: It is a little bit trickier than the above method. In this method, you can
set create your own Label control using the Label class. Steps to create a dynamic
label:
Step 1: Create a label using the Label() constructor is provided by the Label class.
// Creating label using Label class
Label mylab = new Label();
Step 2: After creating Label, set the properties of the Label provided by the Label class.
// Set the text in Label
mylab.Text = "GeeksforGeeks";
// Set the location of the Label

mylab.Location = new Point(222, 90);
// Set the AutoSize property of the Label control

mylab.AutoSize = true;
// Set the font of the content present in the Label Control

mylab.Font = new Font("Calibri", 18);
// Set the foreground color of the Label control

mylab.ForeColor = Color.Green;
// Set the padding in the Label control

mylab.Padding = new Padding(6);
Step 3: And last add this Label control to form using Add() method.
// Add this label to the form
this.Controls.Add(mylab);
Example:
using System;
using System.Data;
using System.Linq;
using System.Text;

20
public Form1()
{
}

{
// Creating and setting the label

Label mylab = new Label();
mylab.Text = "GeeksforGeeks";
mylab.Location = new Point(222, 90);
mylab.AutoSize = true;
mylab.Font = new Font("Calibri", 18);
mylab.ForeColor = Color.Green;
mylab.Padding = new Padding(6);
// Adding this control to the form

this.Controls.Add(mylab);
}
}
}
Output:
ListBox in C#?
In Windows Forms, ListBox control is used to show multiple elements in a list, from
which a user can select one or more elements and the elements are generally
displayed in multiple columns. In ListBox, you are allowed to set the font of the
content present in the ListBox using Font Property of the ListBox which makes your
ListBox more attractive. You can set this property in two different ways:
1. Design-Time: It is the easiest way to set the font of the content present in the
ListBox as shown in the following steps:
 Step 2: Drag the ListBox control from the ToolBox and drop it on the windows form.
You are allowed to place a ListBox control anywhere on the windows form according to

21
your need.
 Step 3: After drag and drop you will go to the properties of the ListBox control to set
the font of the content present in the ListBox.
Output:

22
2. RunTime: It is a little bit trickier than the above method. In this method, you can
set the font of the content present in the ListBox control programmatically with the
help of given syntax:
public override System.Drawing.Font Font { get; set; }
Here, Font indicates the font applied on the content displayed by the ListBox. The
following steps show how to set the font of the content present in the ListBox
dynamically:
Step 1: Create a list box using the ListBox() constructor is provided by the ListBox class.
// Creating ListBox using ListBox class constructor
ListBox mylist = new ListBox();
Step 2: After creating ListBox, set the Font property of the ListBox provided by the ListBox
class.
// Setting the font of the ListBox
mylist.Font = new Font("Bradley Hand ITC", 12);
Step 3: And last add this ListBox control to the form using Add() method.

Example:
using System;
using System.Data;
using System.Linq;
using System.Text;
public Form1()
{
}

{
// Creating and setting the
// properties of ListBox
ListBox mylist = new ListBox();
mylist.Location = new Point(287, 109);
mylist.Size = new Size(120, 95);
mylist.Font = new Font("Bradley Hand ITC", 12);
mylist.Items.Add("Geeks");

RadioButton in C#
In Windows Forms, RadioButton control is used to select a single option among the
group of the options. For example, select your gender from the given list, so you will
choose only one option among three options like Male or Female or Transgender. In
C#, RadioButton is a class and it is defined
under System.Windows.Forms namespace. In RadioButton, you are allowed to
display text, image, or both and when you select one radio button in a group other
radio buttons automatically clear. You can create RadioButton in two different ways:
1. Design-Time: It is the easiest way to create a RadioButton control as shown in
the following steps:

C# GroupBox Class
Last Updated: 05-09-2019
In Windows form, GroupBox is a container which contains multiple controls on it and

the controls are related to each other. Or in other words, GroupBox is a frame
display around a group of controls with a suitable optional title. Or a GroupBox is
used to categorize the related controls in a group. The GroupBox class is used to
represent the windows group box and also provide different types of properties,
methods, and events. It is defined under System.Windows.Forms namespace. The
main use of a group box is to hold a logical group of RadioButton controls.
In C# you can create a GroupBox in the windows form by using two different ways:
1. Design-Time: It is the easiest way to create a GroupBox as shown in the
following steps:

31

 Step 2: Next, drag and drop the GroupBox from the toolbox on the form.
 Step 3: After drag and drop you will go to the properties of the GroupBox to modify
GroupBox according to your requirement.

PictureBox Control
This control is used to add images to the Windows Forms. Let's see how we can
implement this with an example shown below.
Step 1) The first step is to drag the PictureBox control onto the Windows Form
from the toolbox as shown below
Step 2) The next step is to actually attach an image to the picture box control.
This can be done by following the below steps.

36
1. First, click on the Image property for the PictureBox control. A new
window will pops out.
2. In this window, click on the Import button. This will be used to attach an
image to the picturebox control.
3. A dialog box will pop up in which you will be able to choose the image to
attach the picturebox
4. Click on the OK button
One you make the above changes, you will see the following output
Output:-
From the output, you can see that an image is displayed on the form.
