We are using Telerik WPF controls (ver. 2011.2.920.35) and we are trying to accomplish tooltips in the case of a validation failure in one of the grid cells.
Attached is a screenshot that highlights two cells - one with a combobox and the other with a text field. We want the validation errors to be presented for the cell with a combobox just like the way it gets presented for a text field column.
