Rebind with timer

[ghini]

Hi all,
I have an ASPX page with RadGrid control.
I need to refresh the RadGrid every 5 seconds.

I tried with this:

Protected Sub form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles form1.Load

    If Not IsPostBack Then

        Dim aTimer As Timer = New Timer(2000)

        AddHandler aTimer.Elapsed, AddressOf timer_Elapsed

        aTimer.AutoReset = True

        aTimer.Enabled = True

    End If

End Sub



Private Sub timer_Elapsed(ByVal sender As Object, ByVal e As System.Timers.ElapsedEventArgs)

    RadGrid1.Rebind()

End Sub

but I received an "InvalidOperationException: Script controls may not be registered after PreRender".

Any suggestions?

Thanks to all

Hello,


I found a demo which shows how to use Timer to update grid content in regular interval. Have a look in this.
Grid / Server Binding


Another example demonstrates how to perform RadGrid client-side data-binding to visualize live data using web service.

Beautiful, quick and easy.
I resolved this issue using the Ajax Timer Control...

Thank you very much!
