ClientScript.RegisterStartupScript not working

Csharp picture Csharp · May 10, 2013 · Viewed 41.1k times · Source

I have searched SO & google, but I can't seem to get this to work. The code is in the codebehind click event of a "Cancel" button in my asp.net application but does not seem to close the popup window. Any ideas?

try
{
    if (btnCancel.Text == "Close")
    {
        String csName1 = "PopupScript";
        Type csType = this.GetType();

        ClientScriptManager cs = Page.ClientScript;
        if (!cs.IsClientScriptBlockRegistered(csType, csName1))
        {
            ClientScript.RegisterStartupScript(GetType(), "ClosePopup", "window.close();", true);
        }
    }
}  

Update: After postback, when I look at the source page, the only code I see related is:

//<![CDATA[
(function() {var fn = function() {$get("ToolkitScriptManager1_HiddenField").value = '';Sys.Application.remove_init(fn);};Sys.Application.add_init(fn);})();window.close();
document.getElementById('ValidationSummary1').dispose = function() {
    Array.remove(Page_ValidationSummaries, document.getElementById('ValidationSummary1'));
}

You can use this instead

ScriptManager.RegisterStartupScript(this.Page, GetType(), "ClosePopup", "window.close();", true);

or you can also try this one

Page.ClientScript.RegisterClientScriptBlock(typeof(Page), "ClosePopup", "window.close();", true);

Have a Good day.
