ClientScript.RegisterStartupScript: script injected, but not executed

By , 11/08/2011 12:04 AM

This was one weird mystery. I have used ASP.NET’s method ClientScript.RegisterStartupScript countless times to inject client-side JavaScript into page’s markup from the server-side code and it always worked perfectly. This time I created a very basic page from scratch:

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>My Page</title>
    <script type="text/javascript" src="script1.js" />
    <script type="text/javascript" src="script2.js" />
    <script type="text/javascript" src="script3.js" />
    <form id="xfrmMain" runat="server">

And then injected client-side script into it:

ClientScript.RegisterStartupScript(Me.GetType, "JSCode", "ProcessData();", True)

where ProcessData() is function from one of the scripts, loaded in the HEAD tag. The script injected just fine, I got a beautiful insert at the bottom of the rendered page:

<script type="text/javascript">

The problem was – it didn’d do squat – the script did not execute. Why? Continue reading 'ClientScript.RegisterStartupScript: script injected, but not executed'»
