Bug in Telerik.Web.UI.RadMenuItem.set_selected()

[Gunnar]

Hi,

The following code produces the right output the first time the button is pressed.
But the second time and there after all menu items will return false when calling get_selected()

Hi Gunnar,

You should also reset the selected item when removing all the items like this:

var ctxMenu = Sys.Application.findComponent('ctx');
ctxMenu._clearSelectedItem();
ctxMenu.get_items().clear();

and get_selected() method will return correct values.

All the best,

Hi,

Thank's for the quick reply.

I consider this solution as a workaround.

ctxMenu._clearSelectedItem() is a private method and does not exist in the documentation. This method isn't in the public API.
ctxMenu.get_items().clear() should also clear the current selected item in the menu.
And menuItem.set_selected(true) should really set the item to selected even if a removed item is selected.
