The single click of RadSplitButton is used to avoid multiple postbacks/callbacks to the server. This feature is useful in scenarios where the developer should prevent submitting of identical content multiple times to the server.

The following properties should be used to enable the single click functionality:

SingleClick - determines whether the RadSplitButton control will be immediately disabled after the user clicks it. Set it to true to enable the single click functionality.
SingleClickText - determines the text displayed in the RadSplitButton control after the button is being clicked and disabled. The original text will be retrieved after the server request execution. The property takes a plain text string.
