how to avoid post-back on button (web control) click in asp.net 2.0?

[loga123]

Hi All,

I have a web page where I would like to do certain activities when user
click's a button.
I have used button web control on my page. Each time, I click this
button....page gets posted.
I don't want my page to do "post-back" when i click on button web
control.
is there any way to accomplish this?
Can anyone help me in this regard?

thanks

If you don't want your button to postback, that is presumably because it can
achieve everything it needs to do client-side i.e. with JavaScript...?

In which case, don't use an <asp:Button> control at all - simply use an HTML
button e.g.

<input type=button id=cmdHello value="Hello" onclick="alert('Hello');">

write your code like thisin Page_load()


if(!Page.IsPostBack)
{

your code

}

You need to use javascript. Check the following
atlas.asp.net

The HTML section in the toolsbox contains plain HTML controls including your
button.
No postbacks..

Are you wanting to post to a different page? If so, there is a
property on the button where you can specify where to post to. If you
are looking for something like javascript, you can use the HTML input,
or put onclick attribute as the javascript you want to do, followed by
"return false;" and i believe that will work for you.

That doesn't prevent a post-back. It only prevents the code to be
executed when the post-back happens.

How would that stop a postback...?

Thanks

The return false really stop the postback. I had the simllar problem in which I wanted to use a Web Control (custom look and feel, didn't want to write CSS again) but I didn't want to use it for postback. I just added the attribute like this:

''Visual Basic.Net
btnNoPostBackButton.Attributes.Add("OnClick", "DoSomething(); return false;")

This worked wonderfully for me. Thanks

God Bless!
