Mutually Exclusive Checkbox

[Mohammed Imaduddin]

Does anyone know if there is a way to get a Mutually Exclusive Checkbox with this listbox control. Like the one available thru the Ajax Toolkit?

Hello Mohammed,

You can achieve the same functionality by using client-side API of RadListBox control.

Attach the OnClientItemChecked event to RadListBox and check/uncheck the corresponding item after getting reference the item. Use the findItemByText/findItemByValue/findItemByAttribute methods for getting reference to corresponding item. Then use the set_checked() method to check/uncheck the item.

Hope the following links would be helpfull for you:

I don't know about findItemByText/findItemByValue/findItemByAttribute BUT for those who's looking for a quick fix.  Here it is.

function rlboxRoles_ItemChecked(sender, args) {
        var listbox = sender;
        var items = listbox.get_items();
        var count = items.get_count();
        var checkedItem = args.get_item();
        var index = items.indexOf(checkedItem);
        for (var i = 0; i < count; i++) {
            if (i != index) {
                items.getItem(i).set_checked(false);
            }
            else {
                items.getItem(i).set_checked(true);
            }
        }
    }
