I'm developing a dnn module and I used a template for this.
I have my module.ascx and I want to open a popup window. How would I do this?

I tried these from my code behind but it doesn't work:
1. ScriptManager.RegisterClientScriptBlock(this.Parent, this.Parent.GetType(), "showPopup", "window.open('http://www.google.com')", true );
2. Response.Write("<script>window.open('" + url + "');</script>");

I'm calling the popup window during an imagebutton onclick and I need to process some arguments.

This call works fine: Response.Write(" "); but this call does not: Response.Write(" "); It cannot reference a physical file on the Module Directory.

sigh... I've been playing around NavigateUrl but it looks like this is used for friendly URLs. I just want to call my own aspx page... Really need some help on this one.

private string GetImagePreviewUrl()
{
//DotNetNuke.Common.Globals.NavigateURL(333;
TabController tabController = new TabController();
TabInfo tabInfo = tabController.GetTabByName("ImagePreview.aspx", PortalId);
return DotNetNuke.Common.Globals.NavigateURL(tabInfo.TabID);
}
