How to select/remove the item from list box (single selection mode)?
I need to move item from listBox1 to listBox2.
Both list boxes are in single selection mode.
Clicks the item1 in ListBox1 and button Add, it works. The item is removed from listBox1 and appears in listBox2.
Clicks the item2 in listBox1 and button Add, it fails. The error message:
System.Web.HttpException: Cannot have multiple items selected when the SelectionMode is Single.
How do I fix this?
