    I am trying to open the radwindow on button click event from server side. when I do the same from  client side with postback="false" and Onclientclicked="openRadWin" everything works fine. But If I enable the postback and try to call the javascript function openRadWin from server side  that opens the radwindow , it is not working.

    I am trying to open the radwindow based on the some condition and do some processing and return back to same original page after it completes. Below is my code snippet.


    <script type="text/javascript">
    function openRadWin() {
                var width = 400;
                var height = 400;
                var left = 200;
                var top = 200;/
                radopen("popupMsg.aspx", "RadWindow1", width, height, left, top);



    <telerik:RadScriptManager ID="mgr" runat="server"></telerik:RadScriptManager>
    <telerik:RadSkinManager ID="RadSkinManager1" runat="server" ShowChooser="true" Visible="false"/>

    <telerik:RadWindowManager ID="RadWindowManager1" runat="server" EnableShadow="true">
    <telerik:RadWindow ID="RadWindow1" runat="server" ShowContentDuringLoad="false" Width="400px"
    Height="400px" Title="Telerik RadWindow" Behaviors="close">

    <div class="demo-container size-thin">
    <telerik:RadButton runat="server" id="radpopup" OnClick="btnad_Click" Text="Open RadWindow" />


      protected void btnad_Click(object sender, EventArgs e)
                RadScriptManager.RegisterStartupScript(Page, Page.GetType(), "test", "openRadWin();", true);

    You need to use the Sys.Application.Load event to execute that function, otherwise it will be called before the controls are instantiated on the client, and you will get a JS error. You can find an example in the following article: http://www.telerik.com/help/aspnet-ajax/window-troubleshooting-opening-from-server.html.
