SelectedCellsChangedEventArgs e)

You need to get DataGridRowfirst to access its Header.
您需要DataGridRow首先访问其Header.
DataGridRow you can get using ItemContainerGenerator.ContainerFromItem()method of sender dataGrid like this:
您可以使用ItemContainerGenerator.ContainerFromItem()发送方 dataGrid 方法获得 DataGridRow，如下所示：
private void Grid1_SelectedCellsChanged(object sender,
SelectedCellsChangedEventArgs e)
{
DataGrid dg = (DataGrid)sender;
foreach (var item in e.AddedCells)
{
DataGridRow row =
(DataGridRow)dg.ItemContainerGenerator.ContainerFromItem(item.Item);
var col = item.Column as DataGridColumn;
MessageBox.Show("" + col.Header);
var fc = col.GetCellContent(item.Item);
if (fc is TextBlock)
{
MessageBox.Show("Values" + (fc as TextBlock).Text);
}
MessageBox.Show("Row Header " + row.Header.ToString());
}
}
