VB.NET TextBox Control
A TextBox control is used to display, accept the text from the user as an input, or a single line of text on a VB.NET Windows form at runtime. Furthermore, we can add multiple text and scroll bars in textbox control. However, we can set the text on the textbox that displays on the form.
Let’s create a TextBox control in the VB.NET Windows form by using the following steps:
Step 1: We have to drag the TextBox control from the Toolbox and drop it on the Windows form, as shown below.
Step 2: Once the TextBox is added to the form, we can set various properties of the TextBox by clicking on the TextBox control.

There are following properties of the TextBox control.
