Axiom list box IsMultiSelectEnabled

Hello,

I'm using a list box to configure a grid template filter. When IsMultiSelectEnabled = false the item boxes change from a checkbox to a radio button, implying one option must always be selected. However I'm able to "uncheck" the selected item. Is this intended?

I would like to have one option always selected. I tried using _onSelectionChange to check if nothing is selected and if so select the first item. This appears to set the SelectedItems property correctly, however the control does not refresh on the screen, still showing nothing selected. This technically works, but I'd like to refresh the list box to show which item is selected. The cleaner solution would be to remove the ability to unselect an item when IsMultiSelectEnabled = false.

I'm using v25.6

Thanks
