Hi Oliver,
I am returning false. Here is what I am doing...
<%@ Page Language="vb" AutoEventWireup ="false" Codebehind="_in dex.aspx.vb"
Inherits="Demo. __index"%>
<html><head><ti tle>Validate</tile>
<script language="JavaS cript" type="text/JavaScript">
<!-- // Hide older browser
function validate()
{
alert("Client-Side validation!");
return false;
}
}
//-->
</script>
<body>
<table>
<tr valign="top">
<td align="center" bgcolor="#fffff f" colspan="2"><br >
<asp:button id="cmdRunRepor t" runat="server" text="Run
Report"></asp:button><br>
<br>
</td>
</tr>
</table>
</body>
</html>
Behind-Code
'/// <summary>
'/// The main entry point for the application.
'/// First validate on client-side
'/// </summary>
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArg s) Handles MyBase.Load
'--// If the page has already loaded do not execute it again
If Not Page.IsPostBack Then
cmdRunReport.At tributes("oncli ck") = "validate() ;"
End If
End Sub
'/// <summary>
'/// Upon click "Run Report" The user is redirected to a "Loading... " page.
'/// </summary>
Private Sub cmdRunReport_Cl ick(ByVal sender As Object, ByVal e As
System.EventArg s) Handles cmdRunReport.Cl ick
Response.Redire ct("Loading.asp x?URL=Invoice.a spx?")
End Sub
The problem is that when I click on the button is will execute the validate
client-side function but it will also execute the server-side
cmdRunReport_Cl ick event. How can I prevent this from happening?

Hi Yama,
If you don't want the post to go ahead, use
return false;
from the JavaScript function.

Hi,
I have a button which is a server-side control. If a client-side error on
a form is produced and a javascript (client-side) is fired how do I avoid
the server-side button_client event to occur? (that is because the page gets
refreshed for no reason even if I say do nothing)
Thank you,
Yama
