Custom key press validation

[Clinton Smyth]

Hi

I have a javascript function that validates client input as they're typing.  If the user types an invalid character, the function (decOnlyKey below) returns false.

function RadComboBoxKeyPressing(combo, eventArgs) {
    var key = eventArgs.get_domEvent().keyCode;
    var allow = decOnlyKey(key, combo.get_text());

//    if (!allow)
//        eventArgs.set_cancel(true);
}

It appears this eventArgs object does not have a set_cancel method (hence commented out above).

How can I get the RadComboBox to reject the key press?

Thanks

Hello Clinton,

A better option would be attaching onkeydown event to combo input textbox from client side and canceling the event based on condition. More information on this can be found here.
