Can you think of an easy way to make this work for asp:RadioButtonList It seems to have a but of trouble locating Validators on those and throws a null exception when it checks control.Validators.length
How can I handle ValidationGroup with this script ?
Now it works perfect, thank you!!!
Excellent! I am just having troubles when using a form in an updatepanel. Any idea what I should do?
Wrap it inside
function pageLoad() {
}
Nice it works well. Thanks
