OnClientClearButtonClicking
OnClientClearButtonClicking
The OnClientClearButtonClicking client-side event immediately when the Clear button in the entry area of the RadDropDownTree is clicked.
The event handler receives two parameters:
-
The instance of the RadDropDownTree client-side object.
-
An Event argument parameter.
The event can be cancelled - simply set args.set_cancel to true - args.set_cancel(true); from the event handler and the RadDropDownTree dropdown will not be opened.
