VB.NET ListBox Control
The ListBox control is used to display a list of items in Windows form. It allows the user to select one or more items from the ListBox Control. Furthermore, we can add or design the list box by using the properties and events window at runtime.
Let’s create a ListBox control in the VB.NET Windows by using the following steps.
Step 1: Drag the ListBox control from the Toolbox and drop it to the Windows form, as shown below.
Step 2: Once the ListBox is added to the Form, we can set various properties of the Listbox by clicking on the ListBox control.
ListBox Properties
There are following properties of the ListBox control.
| Properties Name | Description |
|---|---|
| AllowSelection | It takes a value that defines whether the list box allows the user to select the item from the list. |
| CanSelect | It obtains a value that determines whether the Listbox control can be selected. |
| ColumnWidth | It is used to get or set the width of the columns in a multicolumn Listbox. |
| Container | As the name defines, a container gets the IContainer that stores the component of ListBox control. |
| Controls | It is used to get the collection of controls contained within the control. |
| Created | It takes a value that determines whether the control is created or not. |
| Width | It is used to set the width of the ListBox control. |

| Contains | It is used to check whether the particular item exists in the ListBox or not. |
| Show() | It is used to display the control to the user. |
