I have a c# asp.net 3.5 app I am trying to open a window from code behind after a certain event. I have this but its not working and there are no errors in firebug
When you view the source, after page load, is this code actually rendered into the source?
Can you set a breakpoint at the this.Page.ClientScript...-line, to verify that both conditions before it are actually met?
Assuming that the pre-conditions are true. You need to pass an additional parameter to the RegisterClientStartupScript method call to indicate that scriptTags need to be added.
Page.ClientScript.RegisterStartupScript(this.GetType(), "openCredentials", string.Format("radopen('Services.aspx?clientId={0}, Window_Services')", openCredentialsWindow_ClientId.ToString()),true);
