Код показывает, что моя Datagrid загружается базой данных SQL Server, и при событии двойного щелчка открывается новое окно, и информация о строке Datagrid заполняется в полях текстового поля и поля со списком.
Я пытаюсь отобразить уже выбранный «Тип отчета по утилитам», однако могу только отобразить его в виде элемента со списком со значением windowToOpen.cmb_UtilityRptTyp.Items.Add (row.Row ["ReportType"]. ToString ());
У меня есть некоторый внутренний код, который заполняет это поле со списком, но для события Loaded, которое также извлекается из базы данных SQL Server, но я отключил его для этого примера.
