    I've been trying to get a modal RadWindow to open upon clicking on a button after the code-behind has executed.
    I have tried various suggestions posted on this forum, but none seem to work.  

    I have boiled down my problem page to just the components necessary so you could get a fairly clear look at it.  

    It's behavior right now is to modally gray the entire screen, but the popup window does not show up anywhere.

    If anyone has an idea what I need to change to get it to work, please let me know, I appreciate the help!!

    Please try the following code snippet which works fine at my end.

    private void EditText(object sender, System.EventArgs e)
        string script = "function f(){showWindow(); Sys.Application.remove_load(f);}Sys.Application.add_load(f);";
        ScriptManager.RegisterStartupScript(Page, Page.GetType(), "key", script, true);
        Label1.Text += "Got Here...";

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

    Hope this will helps you.
