В проекте приходится использовать часть контролов из WinForms. В частности DataGridView. Есть код(это просто пример ошибки)

Если кликаем на метке(WPF контрол) то в появившемся меню можно выбирать любой элемент дерева. А если кликаем на ячейку(WinForm контрол) то нет возможности выбрать элемент. Дерево игнорит выделения. В чем проблема?
я не волшебник, я только учусь...
