I am trying to validate a textbox in my page. It cant contains less than 7 characters.
This is what I am doing:

<head>
<script language="JavaScript">
function PassLength( oSrc, txtPass ){ var retValue = true; if(txtPass.length > 7){ retValue = false;} return retValue } </script>
</head>

In my control:
Display = Dynamic
Error Message = You must type more than 7 characters.
ClientValidationFunction = PassLength
ControltoValidate = txtPass

It doesnt work, I was searching more in the net and found in some sites 2 functions, one for the server and one for the client? I didnt understand very well. Could someone give me tips and help about this subject?

Thanks
Gis.

//Not less then 7 characters
function ValidLength( source, arguments ){
if( arguments.Value.length < 7 )
arguments.IsValid = false;
else
arguments.IsValid = true;
}

this should work. if you get errors try changing the capitalization of:
Value -> value
-or-
length -> Length

Jason, I added your function inside of my head tag in my aspx (html part), only this function is there, and connected it to my custom control. But it doesnt work. Should I add something else?

is it erroring out or not firing?
check to make sure the button/link you click to validate has [tt]CausesValidation = true[/tt]

you may also want to try:
if( len(arguments.Value) < 7 )
I don't think this will work, but it's worth a shot.

If your still having issues, post your HTML and i'll take a look at it.

try changing the name of the values you pass to the function. I pretty sure they have to be 'source', and 'agruments'.

also make sure to wrap your entire sever side code for the custom validator in
try
agrs.isvalid = len(agrs.value) > 7
Catch
agrs.isvalid = false
end try
