Gets or sets whether pressing the delete key raises the Delete event when an item is selected in the drop-down suggestion list.
true if delete key capturing should be enabled; otherwise, false;
Setting this property to true causes the Delete event to be raised when the delete key is pressed and an item is selected in the drop-down suggestion window. Items are never deleted automatically; it is up to you to handle the Delete event and provide your own deletion code.
Setting this property also changes the autocompletion behavior when arrow keys are pressed. When AllowDelete is false, and the up or down key is pressed to choose an item in the list, the contents of the text box are changed to the new item text. When AllowDelete is true, the contents of the text box are not changed when a new item is selected. This mimics the behaior of existing applications that support the delete key, such as Internet Explorer.
