By "not working", can I assume you mean the GridView is not hidden when clicking the radio button?

The GridView must be in the Update panel with the radio button.  Update panels, by definition, only update the contents within the panel.

If you want gridview be visible and hide based on radio buttons, include Gridview also in UpdatePanel.

Note: before showing gridview make sure you are adding the records to it.

Hi msaahil,

Please try to set UpdateMode="Conditional" and call . Update() method to update UpdatePanel content.

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">

    Protected Sub Radiobutton1_CheckedChanged(sender As Object, e As EventArgs)
        GridView1.Visible = True

        UpdatePanel1.Update()
    End Sub
    Protected Sub Radiobutton2_CheckedChanged(sender As Object, e As EventArgs)
        GridView1.Visible = False

        UpdatePanel1.Update()
    End Sub

Best Regards,

Hello

I tried the way u all said it works fine but I have more than 2 radiobuttons and gridviews

so when I try to add another scriptmanager before UpdatePanel2...it shows error that only one script manager can be added on one page

so what do I do?will just one script manager work for all updatepanels on a page?

You only need one script manager.  One script manager for each update panel is not required.

This is a design issue that you must work through.
