I have an <asp:ImageButton ...> which I do some client side validation with
by adding an Attribe for the on click.

How do I tell asp NOT to submit if my function does not validate? I've
tried returning false but to no avail.

I'm sure it's obvious when I know how!

Thanks RSB.

Returning False should work. as i am using this.
Are you execute another function in the Click function .. if yes make sure
that you are returning the False in the Click Function.
Click to expand...
function submitVoucher(thisImg, textName)
{
theImage = thisImg;
var elVC = getElement(textName);
if (VoucherIsOK(elVC))
{
return true;
}
else
{
if (elVC.value.length <17)
alert('You have not entered enough characters for a Voucher
Code.\n Please check and enter again carefully.');
else
alert('You have entered an invalid Voucher Code.\n Please check
and enter again carefully.');
return false;
}
}

is my js function and

GoButton.Attributes.Add("onClick", "submitVoucher(this, '" +
VoucherCode.ClientID + "');");

is how I'm getting it there.

Should this be OK?
