    }

    void CheckBrowserCaps()
    {
        String labelText = "";
        System.Web.HttpBrowserCapabilities myBrowserCaps = Request.Browser;
        if (((System.Web.Configuration.HttpCapabilitiesBase)myBrowserCaps).CanRenderMixedSelects)
        {
            labelText = "Browser supports HTML OPTION elements which specify both ONPICK and VALUE attributes.";
        }
        else
        {
            labelText = "Browser does not support HTML OPTION elements which specify both ONPICK and VALUE attributes.";
        }

        Label1.Text = labelText;
