VB.NET CheckedListBox Control
The CheckedListBox is similar to Listbox except that it displays all items in the list with a checkbox that allows users to check or uncheck single or multiple items.
Let’s create a CheckedListBox control in the VB.NET Windows form using the following steps.
Step 1: Drag the CheckedListBox control from the Toolbox and drop it to the Windows form, as shown below.
Step 2: Once the CheckedListBox is added to the Form, we can set various properties of the CheckedListbox by clicking on the CheckedListBox control.
CheckedListBox Properties
There are following properties of the CheckedListBox control.

| AccessibilityObject | It obtains a value that determines whether the AccessibilityObject is assigned to the CheckedListBox control. |
| AccessibleName | It gets or sets a value that tells if the accessible client application has used the name of the checkedlistbox control. |
| AllowSelection | It gets a value that indicates whether the ListBox allows for the item to be selected from the list. |
