What is the purpose of the Page.RegisterClientScriptBlock method? Can
anyone supply some sample code

TIA

It inserts client-side script into your page. There are a few related
methods that insert script inside a <form> tag and at the end of a page.

It's particularly important when building a webcontrol that uses client-side
script: if you have two instances of the same control, the script block only
gets added once to the page.

I tried that but didn't get anywhere with it.

Well here's my code in the PageLoad handler:

private void Page_Load(object sender, System.EventArgs e)
{
Page.RegisterClientScriptBlock("mykey", "alert(\"hi\")");
}

It didn't work - no script was emitted in the generated web page. I've also
tried a literal <script> tag but no joy. Any ideas? Or is this NYI in Beta
2?

You forgot the script tags:

Page.RegisterClientScriptBlock("mykey", "<script>alert(\"hi\")</script>");

This is strange because it works for me. What error message do you get when
compiling? Can anyone else verify this code? It just throws up an alert.

Anyway, here's the content of my startup.aspx.cs file.

using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;

namespace p450_cs_work
{
/// <summary>
/// Summary description for startup.
/// </summary>
public class startup : System.Web.UI.Page
{

private void Page_Load(object sender, System.EventArgs e)
{
Page.RegisterClientScriptBlock("mykey",

"<script>alert(\"hi\")</script>");
}

#region Web Form Designer generated code
override protected void OnInit(EventArgs e)
{
//
// CODEGEN: This call is required by the ASP.NET Web Form Designer.
//
InitializeComponent();
base.OnInit(e);
}

/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
{
this.Load += new System.EventHandler(this.Page_Load);
}
#endregion
}
}

BTW, my code is using the release version. I don't know about when this
might have been introduced.

Thanks for that, yeah I guess that method is NYI in beta 2 because my code
is as simple and similar that which you presented.
