[Solved] combo box client side validation

[bob ter]

Hi,

I have a populated combo box with 'allow custom text' and 'mark first match enabled' in order for users to be able to type in the box and have any matches autopopulate.

However I would like to validate on the client side for when they type something into the box which isn't in the populated list. Ive tried using a required field validator but as theres something in the box they dont catch that whats in the box isn't in the list.

Any ideas?

Hello,

Attach 'OnClientBlur' event to RadComboBox for checking whether the typed value is present in RadComboxItem collection, if not set the combo text as blank.

Client Code:

    function OnClientBlur(sender, args) {
        var check = false;
        for (var i = 0; i < sender.get_items().get_count(); i++) {
            if (sender.get_text() == sender.get_items()._array[i].get_text()) {
                check = true;
            }
        }
        if (!check)
            sender.set_text('');
    }

Hope this help you,
Shinu.
