如何在WPF DataGrid中按索引獲取行

Question

我有一個數據網格，當我在此數據網格上加載數據時，我要關注選定的行。 但我沒有得到索引。

if (gridAppointment.SelectedIndex >= 0)
{
   gridAppointment.ScrollIntoView(gridAppointment.Items[gridAppointment.SelectedIndex]);
   DataGridRow row = (DataGridRow)gridAppointment.ItemContainerGenerator.ContainerFromIndex(
         gridAppointment.SelectedIndex);
   if (row != null)
       row.MoveFocus(new TraversalRequest(FocusNavigationDirection.Next));                                               
 }

Answer 1

當選擇該行時，下一個條件為true，這樣便可以獲取所有像元值。

if (gridAppointment.SelectedIndex >= 0)
{
    DataRowView dataRow = (DataRowView)gridAppointment.SelectedItem;
    int i = dataRow.Row.ItemArray[0].ToString();
    // ItemArray[1] is the next column and so on.
}
