Answer / gaurav k

SelectedIndexChanged is a event for the DropDown Control.
True is a bool type. We can not compare an event with bool
type like this. If we have to do somthing on the change of
the selection of an item, we can write the appropriate code
in the SelectedIndexChanged Event.

protected void DropDownList1_SelectedIndexChanged
(object sender, EventArgs e)
{
//Code
}
