Question

I have an ASP.NET user control that I want to write some dynamic Javascript to (basically a JQuery call to open an accordion node).

To complicate matters, I’m using history points. In a nutshell, I need to open a JQueryUI accordion based on a value in the history point data stored in the URL.

I’ve got the part that sets the history points working, and I can step through my code (below) as I navigate the history. The problem is, in this example, my script never renders on the page.

protected void uxScriptManager_OnNavigate(Object sender, HistoryEventArgs e)
    { 
        if(!String.IsNullOrEmpty(e.State["activeTab"]))
        {
            ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "xScript", "alert('Hello,world!');", true);
        }
    }

Am I doing something wrong?

Addendum

I’ve been tinkering, and it seems like my call to register the clientscriptblock works fine in other events…but in the Navigate event for the scriptmanager, I can’t write new script out to the page. I’m thinking what I’m trying to do isn’t possible…

It looks like you need to add script by calling ScriptManager.RegisterStartupScript method to show elements on page:

ScriptManager.RegisterStartupScript(this, this.GetType(), this.ID,
“”alert(‘Hello,world!’);”, true);
