use javascript. basically, use an alert function within the body of the page itself.

[mendhak]

<script language="JavaScript">
alert('Hello Cruel World!');
</script>

Of course, there are many places you'd use it. Like the onClick event of a button, or page load event, etc.

[Winanjaya]

So there is no ASP.NET code for doing this? ..
please advise

It depends. Where and when do you want this shown?

[Winanjaya]

I want to show it at client side.. any idea?

thanks

[mendhak]

Button1.Attributes.Add("onClick", "javascript:alert('Hello');")

Or make it a call to an existing function.

[Winanjaya]

Where should I put them? .. in Page_load or what? .. please advise .. sorry I am very new with this..
thanks a lot in advance

[mendhak]

Sure, put it in page load. That vb.net code above adds this:

<input type="button" value="Click me!" onClick="javascript:alert('hello');>

hi,
you could do a little futher on that, you could do it in an event doing something like this
dim sScript as string="<script language=javascript>"
sScript +="alert(""" your message variable or otherwise """");"
sScript +="</script>"
If not Page.IsStartupScriptRegistered("nameofyourscript") then
page.registerstartupscript("nameofyourscript",sScript)
end if
end sub
Just be aware that when you try to find the isstartupscriptregistered and the registerstartupscript with the inteligicence you wouldn't find then so you have to type them all

Hope this helps a little bit more
