WPF, besides this how can we have a XamMultiComboEditor as Readonly, I mean we can only see what all are checked items but can not change the selection of them ?

Hi bankawat1,

The behavior of displaying the tooltip for the selected item of the XamMultiColumnComoEditor is certainly possible; you can achieve this by first setting up your tooltip, then within ToolTipService, set the ShowOnDisabled property to true.

I have constructed and attached a sample which demonstrates this behavior.

As for your second inquiry, I am not exactly sure what you are trying to achieve.

If you are trying to prevent changes to the SelectedItem while still allowing access to the combo’s dropdown, then it should be possible to store the previously SelectedItem, (get SelectedIndex or SelectedItem, during the DropDownOpening event) and then during the DropDownClosing event, compare the actual SelectedItem to your stored value; if they are different, set the actual SelectedItem to your stored value; this will effectively provide a read-only behavior as you will be able to view the combo’s dropdown content while preserving the selected value.

Please let me know if I have misunderstood your intention.

If you have any further questions in the meantime, please let me know.
