    I have a page that sits inside a master page so I do not have a body to do an onload statement, by research everyone says use the registerstartUpscript and it will work, however it is not.  How can I call a radwindow on page load from a page nested in a master site.  Thanks

    function SelectInfo() {
    <telerik:RadWindow ID="rwInfo" runat="server" Modal="true" NavigateUrl="Info.aspx" Width="1000px" Height="800px" OnClientClose="closeWindow"></telerik:RadWindow>
    Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
          If Not IsPostBack Then
              Dim userlogon As String = Split(Current.User.Identity.Name, "\")(1)
              HFUserId.Value = GetUserId(userlogon)
              If CheckIMOs(userlogon) = True Then
                  Dim page As Label = CType(Master.FindControl("lblPage"), Label)
                  page.Text = " - Move Add Change"
                  ScriptManager.RegisterStartupScript(page, page.GetType(), "SomestartupScript", "SelectInfo();", True)
              End If
          End If
      End Sub

    Hi Kevin,

    I guess that you want to show a RadWindow, which is inside the MasterPage on the PageLoad of content page. Please have a look into the sample code snippet which works as expected for me. Please elaborate your requirement if it doesn't help.

    Master Page:
    <telerik:RadWindow ID="RadWindow1" runat="server">
            <telerik:RadTextBox ID="RadTextBox1" runat="server" Text="Demo">

    Content Page VB:
    Protected Sub Page_Load(sender As Object, e As EventArgs)
        Dim script As String = "function f(){showWindow(); Sys.Application.remove_load(f);}Sys.Application.add_load(f);"
        ScriptManager.RegisterStartupScript(Page, Page.[GetType](), "key", script, True)
    End Sub

    <script type="text/javascript">
        function showWindow() {
            $find("<%=RadWindow1.ClientID %>").show();

    Hello Kevin,

    There are two key points in this code that can prevent a RadWindow from showing up:

    • the Sys.Application.Load event should be used if the RadWindow is disposed (i.e., a full postback or a partial postback that includes the RadWindow are initiated), as shown here:
    • The Response.Redirect call (if executed), will change the entire pages response, so the script registration will not travel to the client, but only a redirect to the new page.

    I hope this helps.
