Hi Rick,

Thanx for the heads up. I got everything installed and modified on one of my simple mm.net web forms. Actually all I did was drop SciptManager on the form. Then I dropped UpdatePanel on the form, being careful to insure the ScriptManager is above UpdatePanel or you get an error.

Then I simply dragged over a server button (btnSubmit) and label (lblQuadrant) onto UpdatePanel. I set a couple of properties on UpdatePanel so that I get an AsynPostBack and to acknoedge the click of btnSubmit. When I click btnSubmit, lblQuadrant gets it’s text property updated without the full postback. That is so cool. But now the rub. The sever-side method code in the click event of btnSubmit is:

protected void btnSubmit_Click(object sender, System.EventArgs e)
{
  int jj;
  CheckBox oChk;
  // upper right adult teeth
  for (jj = 1; jj<=52; jj++)
  {
	oChk = (CheckBox)this.FindControl("chk" + jj.ToString());
	if (oChk.Checked)
	{
         this.lblQuadrant.Text = this.lblQuadrant.Text +  "<li>" + oQuadrants[jj, 1] + "  (" + oQuadrants[jj, 2] + ")" + "</li>";                
         
        this.btnLetter.Enabled=true;  
        }
}

Notice that the method code also sets btnLetter.Enabled=true;
Since btnLetter is not in the UpdatePanel, it does not get Enabled. Could I register a StartupScript on the page from this method to run when the UpdatePanel updates?

I was hoping that the following script could run when UpdatePanel updates.
The script that I think will work is below. But how do I hook it into the AJAX scheme of things?

System.Text.StringBuilder myScript = new System.Text.StringBuilder();
                myScript.Append("<script language='javascript'>");
                myScript.Append("\n  var oBut= document.getElementById(‘btnLetter’);");
                myScript.Append("\n oBut.setAttribute(‘disabled’,false)”);
                myScript.Append("</script>");
                Page.ClientScript.RegisterStartupScript(this.GetType(), "EnablebtnLetter", myScript.ToString(), false);
