You can do somthing like this.

    Private Function DidControlCausePostBack(ByVal uniqueID As String) As Boolean
        Dim bool As Boolean = False
        bool = (Not Request.Form(uniqueID) Is Nothing) OrElse (Not Request.Form("__EVENTTARGET") Is Nothing AndAlso Request.Form("__EVENTTARGET").Equals(uniqueID)) OrElse ((Not Request.Form(uniqueID & ".x") Is Nothing) AndAlso (Not Request.Form(uniqueID & ".y") Is Nothing))
        Return bool
    End Function

This will return true/fase depending on the check. Hope this helps.

Note: code is in vb.net.

Hi,

I guess it can be done in the following way
1> Write a common function btnCommon_Click and add to the event handler when any button is clicked.
2>This function will keep a list of all the buttons which all are clicked
3>Finally when you do a submit take care of all the clicked buttons.

I hope it will solve the purposs
