I have this in my base class


// this keeps the form action correct during ajax postbacks
            string formActionScript = "<script type=\"text/javascript\">"
                + "Sys.Application.add_load(function() { var form = Sys.WebForms.PageRequestManager.getInstance()._form; form._initialAction = form.action = window.location.href; }); "
                + "</script>";

            Page.ClientScript.RegisterStartupScript(this.GetType(), "formactionset", formActionScript);


I want to call this javascript in the codebehind of the ascx page.
See attached ascx page.

<script type="text/javascript">
<!--

function updateClock ( )
{
  var currentTime = new Date ( );

  var currentHours = currentTime.getHours ( );
  var currentMinutes = currentTime.getMinutes ( );
  var currentSeconds = currentTime.getSeconds ( );

  // Pad the minutes and seconds with leading zeros, if required
  currentMinutes = ( currentMinutes < 10 ? "0" : "" ) + currentMinutes;
  currentSeconds = ( currentSeconds < 10 ? "0" : "" ) + currentSeconds;

  // Choose either "AM" or "PM" as appropriate
  var timeOfDay = ( currentHours < 12 ) ? "AM" : "PM";

  // Convert the hours component to 12-hour format if needed
  currentHours = ( currentHours > 12 ) ? currentHours - 12 : currentHours;

  // Convert an hours component of "0" to "12"
  currentHours = ( currentHours == 0 ) ? 12 : currentHours;

  // Compose the string for display
  var currentTimeString = currentHours + ":" + currentMinutes + ":" + currentSeconds + " " + timeOfDay;

  // Update the time display
  document.getElementById("clock").firstChild.nodeValue = currentTimeString;
}

// -->

what happens when you try this
Page.ClientScript.RegisterStartupScript(this.GetType(), string.Concat("UpdateClock", DateTime.Now.Ticks), "updateClock();", true);

you said you have ajax so you might need something like this then
ScriptManager.RegisterStartupScript(this, this.GetType(),  string.Concat("UpdateClock", DateTime.Now.Ticks), "updateClock();", true);

or if you have update panels on the page replace UpdatePanel1 with the name of your pnael
ScriptManager.RegisterStartupScript(this.UpdatePanel1, this.UpdatePanel1.GetType(),  string.Concat("UpdateClock", DateTime.Now.Ticks), "updateClock();", true);
