Explain the selection options that can be controlled by setting the SelectionMode property of a ListBox.
What will be an ideal response?
With a ListBox, you allow the user to make a single selection or multiple selections by setting the SelectionMode property appropriately. For example, when the SelectionMode property is set to One, the user can make only a single selection from the ListBox. When the SelectionMode is set to MultiExtended, pressing Shift and clicking the mouse or pressing Shift and one of the arrow keys (up, down, left, or right) extends the selection to span from the previously selected item to the current item. Pressing Ctrl and clicking the mouse selects or deselects an item in the list. When the SelectionMode is set to MultiSimple, multiple items can be selected by clicking the mouse or pressing the spacebar. When the SelectionMode is set to None, no items can be selected.
