OK, I got it:
<%@ Page Language="C#"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
public void Page_Load(Object sender, EventArgs e)
{
// Define the name, type and url of the client script on the page.
String csname = "ButtonClickScript";
String csurl = "~/script_include.js";
Type cstype = this.GetType();
// Get a ClientScriptManager reference from the Page class.
ClientScriptManager cs = Page.ClientScript;
// Check to see if the include script exists already.
if (!cs.IsClientScriptIncludeRegistered(cstype, csname))
{
cs.RegisterClientScriptInclude(cstype, csname,
ResolveClientUrl(csurl));
}
//for the body onload functionality
string temp = "displaymessage()";
HtmlGenericControl body =
(HtmlGenericControl)Master.FindControl("Body");
body.Attributes.Add("onload", temp);
}
<html >
<head>
<title>ClientScriptManager Example</title>
</head>
<body>
<form id="Form1" runat="server">
<div>
<input type="text"
id="Message"/>
<input type="button"
value="ClickMe"
onclick="DoClick()"/>
</div>
</form>
</body>
</html>
This example requires a JavaScript file named Script_include.js with the
following contents:
function DoClick() {Form1.Message.value='Text from include script.'}
function displaymessage()
{
alert('Hello World!');
}
*** add <body runat="server" id="body"to masterpage for the pageload
functionality
