    Server-side Events

    Select a command
    Event log

    RadSplitButton exposes several server-side events that allow easy and flexible use in a wide range of application scenarios:

    • OnClick—raised when the RadSplitButton is clicked and AutoPostBack is set to true.
    • OnCommand—raised when the RadSplitButton is clicked and AutoPostBack is set to true. It is useful for handling commands (using the CommandName and CommandArgument properties). When button is clicked e.CommandName is the CommandName set for the SplitButton itself. When Item in the ContextMenu is clicked, the e.CommandName is the Value of the clicked item.
