Windows Forms is a UI technology for. NET, a set of managed libraries that simplify common app tasks such as reading and writing to the file system. When you use a development environment like Visual Studio, you can create Windows Forms smart-client apps that display information, request input from users, and communicate with remote computers over a network.
In Windows Forms, a form is a visual surface on which you display information to the user. You ordinarily build Windows Forms apps by adding controls to forms and developing responses to user actions, such as mouse clicks or key presses. A control is a discrete UI element that displays data or accepts data input. Step 2 Once the label has been added, go to the properties window by clicking on the label control. In the properties window, go to the Text property of each label control.
A textbox is used for allowing a user to enter some text on the Windows application in C. We will add 2 textboxes to the form, one for the Name and the other for the address to be entered for the user. Step 1 The first step is to drag the textbox control onto the Windows Form from the toolbox as shown below. Step 2 Once the text boxes have been added, go to the properties window by clicking on the textbox control. In the properties window, go to the Name property and add a meaningful name to each textbox.
For example, name the textbox for the user as txtName and that for the address as txtAddress. A naming convention and standard should be made for controls because it becomes easier to add extra functionality to these controls, which we will see later on. A Listbox is used to showcase a list of items on the Windows form. We will add a list box to the form to store some city locations. Step 1 The first step is to drag the list box control onto the Windows Form from the toolbox as shown below.
Step 2 Once the list box has been added, go to the properties window by clicking on the list box control. In the output, you can see that the Listbox was added to the form. You can also see that the list box has been populated with the city values.
A Radiobutton is used to showcase a list of items out of which the user can choose one. Step 2 Once the Radiobutton has been added, go to the properties window by clicking on the Radiobutton control.

Step 1 The first step is to drag the checkbox control onto the Windows Form from the toolbox as shown below.
Step 2 Once the checkbox has been added, go to the properties window by clicking on the Checkbox control. A button is used to allow the user to click on a button which would then start the processing of the form. Step 1 The first step is to drag the button control onto the Windows Form from the toolbox as shown below.
Step 2 Once the Button has been added, go to the properties window by clicking on the Button control. Congrats, you now have your first basic Windows Form in place. When working with windows form, you can add events to controls. An event is something that happens when an action is performed. Probably the most common action is the clicking of a button on a form. In C Windows Forms, you can add code which can be used to perform certain actions when a button is pressed on the form.
The below example will showcase an event for the Listbox control. So whenever an item is selected in the listbox control, a message box should pop up which shows the item selected. Step 1 Double click on the Listbox in the form designer.
By doing this, Visual Studio will automatically open up the code file for the form. And it will automatically add an event method to the code.
