determine difference between an autopostback or a page refresh 2

[blar9]

Is there a way to determine if a user clicked refresh on the page or clicked a control that causes a postback?

Thanks

no, not that I am aware of.

That is a problem, and we are working on it.

You could also look in the EVENTTARGET parameter. I've grabbed an example that we used in an old project where you just pass the page to the function and it returns the control that caused the postback. Presumably, if the control is Nothing when it is returned, then it wasn't a postback. I've not tested this but if you wanted to have a play around with it, here's what was used:

    Public Function GetPostBackControl(ByVal page As System.Web.UI.Page) As System.Web.UI.Control
        ' Find which control caused the postback
        Dim control As Control = Nothing
        Dim ctrlname As String = page.Request.Params("__EVENTTARGET")
        If Not (ctrlname Is Nothing) AndAlso Not (ctrlname = String.Empty) Then
            control = page.FindControl(ctrlname)
        Else
            Dim ctrlStr As String = String.Empty
            Dim c As Control = Nothing
            For Each ctl As String In page.Request.Form
                If ctl.EndsWith(".x") OrElse ctl.EndsWith(".y") Then
                    ctrlStr = ctl.Substring(0, ctl.Length - 2)
                    c = page.FindControl(ctrlStr)
                Else
                    c = page.FindControl(ctl)
                End If
                If TypeOf c Is System.Web.UI.WebControls.Button OrElse TypeOf c Is System.Web.UI.WebControls.ImageButton Then
                    control = c
                    ' break
                End If
            Next
        End If
        Return control
    End Function
