Как я могу отобразить коллекцию всех ошибок проверки ячейки в ControlTemplate DataGridRow?

I have a DataGrid and i validate the user input for each cell. An appropriate error message is displayed for each cell when the user inputs invalid data.
How can I collect and display all row's cell error messages when I hover the ValidationErrorTemplate (controltemplate) on the left hand side of the grid's row?
