You can use Alert('') to show message!

For Javascript, you just need the Alert function as Sunasara Imdadhusen said.

For the code behind, it is a little more complex. As long as the button has a runat="server" attribute, and you have connected up the event handler via OnClick="butLogin_Click" then this should work:

C#

protected void butLogin_Click(object sender, EventArgs e)
    {
    Response.Write("<script>alert('Your Message')</script>"); 
    }

Response.Write? Did you forgot ClientScript.IsStartupScriptRegistered?

Do not try to hijack threads with unrelated questions - it is rude.
Ask a new question if you have a problem.

I suppose you mean showing a message like "User name/Password is invalid" on the webpage? You're talking about validation in that case.

Try the validation controls available on ASP .NET or you can also do the work manually by having a hidden Label control with your message. :)

EDIT: I forgot to add. You can show/hide the Label control (If you prefer this method) in the Button's click event method.

You can take a label control.By default make it invisble..When you have to show some messege make it visible and in the text property of the label assign the messege you want to show..In the page load make the label invisible...............Otherwise you can use the resnponse.wite method.
