RegisterClientScriptBlock does not work from a server control

[Cameron Eckman]

For some reason I cannot get RegisterClientScriptBlock to render a script
reference on the page from a server control. Yes, I have not placed the code
in the Render method, I also tried the OnInit just in case. Below is the a
simple version of the code, any help is appreciated:

namespace MyCompany.Web
{
public class Header : System.Web.UI.WebControls.WebControl
{

private void RenderClientJavaScript(string javaScriptFilename)
{
string script = string.Format(@"<SCRIPT language=""javascript""
src=""/baxScripts/{0}.js""></SCRIPT>", javaScriptFilename);

if (! Page.IsClientScriptBlockRegistered(javaScriptFilename))
Page.RegisterClientScriptBlock(javaScriptFilename, script);
}

protected override void OnPreRender(EventArgs e)
{
base.OnPreRender(e);
RenderClientJavaScript("basicToolset");
RenderClientJavaScript("webMenu");
}

protected override void Render(HtmlTextWriter writer)
{
writer.Write("Hello World");
}

}
}

I've tried your code and it works perfectly, look at the HTML rendered by
the page that contains the control and you will see the script tags

Thanks, your post made me go back and do the simple steps. I've found the
issue I had is that if there is not a <FORM runat=server> tag block on the
page, the script is not written. I didn't read the help deep enough...
