Not sure what your code does but here's an example of a custom validator that shows up in the summary:
VB Code:
<html>
<head>
<script language="javascript">
function ValidateTextBoxes(s,e)
{
var isValid = true;
var tb1 = document.getElementById("txtTextBox1");
var tb2 = document.getElementById("txtTextBox2");
if (s.controltovalidate == "txtTextBox1" && tb2.value.replace(/ /g, "") == "")
isValid = false;
else if (s.controltovalidate == "txtTextBox2" && tb1.value.replace(/ /g, "") == "")
isValid = false;
e.IsValid = isValid;
return;
}
</script>
</head>
<body>
<form runat="server">
<asp:ValidationSummary ID="valSummary" Runat="server"
ShowMessageBox="True" ShowSummary="False" DisplayMode="List"/>
<p>Custom validator used to ensure if you enter something in one
textbox that you must enter sometyhing in the other textbox.</p>
<asp:TextBox ID="txtTextBox1" Runat="server"/><br/>
<asp:CustomValidator ID="valcustTextBox1" Runat="server"
ControlToValidate="txtTextBox1" ClientValidationFunction="ValidateTextBoxes"
Display="None" ErrorMessage="Both textboxes must contain values"/>
<asp:TextBox ID="txtTextBox2" Runat="server"/><br/>
<asp:CustomValidator ID="valcustTextBox2" Runat="server"
ControlToValidate="txtTextBox2" ClientValidationFunction="ValidateTextBoxes"
Display="None" ErrorMessage="Both textboxes must contain values"/>
<asp:Button ID="btnSubmit" Runat="server" Text="Submit"/>
</form>
</body>
</html>

hmm excuse me if my question is a little stupid
when I add a custom validator, I can only write the server side code for it.... So basically for writing a client-side code (your jscript code), you just modify the html source manually? or does the ide give you any options to easily write client side code for custom-validation?

hmmm...I always write my client side code by hand(ie. no IDE short cuts), so i'm not sure if there's an easie way of writing the custom validator jscript functions. I'd think maybe for the pre-canned validators, the IDE would come in handy, but for custom ones it'd be hard for the IDE to guess at your custom validation requirements. So in answer to your question, i just modify the html source manually. BUT i believe there is a way to hook up server side custom event handlers if that's what you're limited to, i just don't remember off the top of my head. I'll keep poking around out of curiousity.
