Events

RadDropDownList supports a number of client-side events that let you customize the behavior of the dropdownlist:

• OnClientDropDownOpening occurs before the drop-down list opens.

• OnClientDropDownOpened occurs after the drop-down list has been opened.

• OnClientItemSelecting occurs before the item's selection.

• OnClientItemSelected occurs after the item is selected.

• OnClientSelectedIndexChanged occurs after the SelectedIndex has been changed in response to a user action.

• OnClientDropDownClosing occurs before the drop-down list closes.

• OnClientDropDownClosed occurs after the drop-down has been closed.

• OnClientLoad occurs after the RadDropDownList has been fully initialized on the client-side.

• OnClientItemDataBound occurs for each item that is created during Web Service(including if ODataSource control is used) binding.
