In postback, alter the contents of field that is shown by Masterpage code-behind
<p>I am writing an asp.net application. In my project some output to page is caused by MasterPage.master.cs code-behind.  Namely, some page header is rendered and few text fields are indicated about current status.</p>

<p>Now I have a situation, when after a postback one of such text fields are altered. Tracing shows that Masterpage code (attached to its Page_Load method)  runs before postback handler. So the field is altered in program but its indication in the header is not altered before I reload the page again - simply because indication happens before handler is invoked.</p>

<p>I need a good way to alter that header after postback. Perhaps some javascript call on onLoad. or some C# trick. I appreciate all the input.
My code is </p>

<pre><code>masterpage.master.cs: 
protected void Page_Load(object sender, EventArgs e) { PROJECTS project = 
Util.getProject(Session); ProjectName.Text = "Project: " + (String)project.NAME;
ProjectName.Visible = true; }
</code></pre>
