Registering Jscript on a Tridion-generated page

Question

I'm attempting to register some javascript on a Tridion-Generated page via a user control. I've created a page object that uses a generic aspx page template. The TBB for the page template contains only the registration for the usercontrol and <!-- TemplateBeginRepeat name="Components" --> @@RenderComponentPresentation()@@ <!-- TemplateEndRepeat -->. The Component Presentation contains 1 component that calls a cp that has an associated tbb that calls the usercontrol. In the usercontrol is the following code:

 protected void Page_Load(object sender, EventArgs e)
    {
         if (Request.QueryString["ID"] == "56")
        {
            ltrClassName.Text = "active";
            ClientScriptManager cs = Page.ClientScript;
            StringBuilder jscript = new StringBuilder();

            jscript.Append("<script type=text/javascript> alert('Hello World!') </");
            jscript.Append("script>");

            cs.RegisterStartupScript(this.GetType(), "PopupScript", jscript.ToString());

        }
        else
        {
            ltrClassName.Text = string.Empty;
        }
    }

When I view the published page and add ID=56 as a parameter to the url, I get 'active' and nothing else. The jscript is not part of the source.

Any reasons why this will not work with Tridion?

Answer 1

I would venture to guess this is not in any way related to Tridion but is in fact a fairly generic .Net related question.

Perhaps this explanation will help? Or in code:

ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "PopupScript", "javascript:alert('Hello World!');", true);
