Checkboxes Select a single node only

[Andy Green]

Hi all

Don't ask - operation reasons, but I have  rad combo box with checkboxes, is it possible to only allow a single checkbox to be selected?

A bit like turning off multiselect, which isn't a property.

Hello Andy,

This behavior can be achieved by subscribing to the ComboBox' OnClientItemChecking client-side handler and canceling the event if the user tries to check more than one checkbox:

function OnClientItemChecking(sender, args) {
    var checkedItems = sender.get_checkedItems();
    var item = args.get_item();

    if (checkedItems.length >= 1 && !item.get_checked()) {
        args.set_cancel(true);
    }
}
