client side validation for custom composite control
 

Hi,
I've been struggling with this for a few days. I've seen bits and pieces
(how to set up custom validation), but I can't seem to understand how to get
client side validation for my custom composite control (the textbox part).
I've done a ton of vbnet, am new to aspnet, but barely know how to spell
java. Anyone know of a good website or tutorial for this kind of thing?

TIA

Re: client side validation for custom composite control
 

I suggest you to use reflector (a disassembler for dotnet).
It permit to study microsoft controls code.
I tink it's the best way.

Re: client side validation for custom composite control
 

The idea is to create a javascript function that looks like this:

<script language='javascript'>
<!--
function MyFunction(source, args)
{
// write javascript logic that determines if there is a error
// set args.IsValid to true or false depending on if there is an error
}
-->
</script>

Assign the function name to the CustomValidator.ClientValidationFunction.

The hard part is figuring out the javascript logic. You will need to specify
the exact goals and related elements on the page for anyone to help with
that.

FYI: I built a replacement to Microsoft's validators that helps avoid most
client-side scripting issues. "Professional Validation And More"
(http://www.peterblum.com/vam/home.aspx) includes 22 validators, all with
client-side support on many more browsers than Microsoft's supports. One of
the most powerful validators is the MultiConditionValidator. Use it to
combine the power of any of the validators in boolean expressions like
[TextBox1 is required and TextBox2 is required and TextBox2 must be a valid
date format].
