StringFormat does not apply in MultiSelectionComboBox selection about timswpfcontrols HOT 4 CLOSED

Hi @ExLuzZziVo

Thank you for posting this 🙏 . I am transferring this control to MahApps (see MahApps/MahApps.Metro#4006 ) and will address this issue there.

I think for now you should be able to overcome this by using a custom SelectedItemTemplate

I have found a solution. In GetSelectedItemsText method of MultiSelectionComboBox.cs I have used this code and it works:

            IEnumerable<object> values;

            if (ReadLocalValue(DisplayMemberPathProperty) != DependencyProperty.UnsetValue && !string.IsNullOrEmpty(DisplayMemberPath))
            {
                values = ((IEnumerable<object>)SelectedItems)?.Select(o => BindingHelper.Eval(o, DisplayMemberPath ?? string.Empty));
            }
            else
            {
                values = (IEnumerable<object>)SelectedItems;
            }

            if (values != null && ReadLocalValue(ItemStringFormatProperty) != DependencyProperty.UnsetValue &&
                !string.IsNullOrEmpty(ItemStringFormat))
            {
                values = values.Select(o => string.Format(ItemStringFormat, o));
            }

Happy holidays!

@ExLuzZziVo thank you for providing your solution. I think I found an even better way, but it will not be implemented here. It will be available in MahApps soon (no due date right now).

Happy new year and happy coding
