The EditChange event notifies your application that the user alters the text of one of the control's edit labels. The control supports single or multiple edit controls in the label area. Use the SingleEdit property to specify that a single edit control is used. Use the EditText property to determine the text of the edit control. Use the KeyDown event to notify your application that the user presses a key. Use the KeyUp event to notify your application that the user releases a key. If the control's Style property is DropDownList, the EditChange event is never fired. Use the AutoComplete property to allow typing values that are not in the column. Use the SelectionChanged event to notify your application that the user changes the selected item.
