WPF DataGrid: modify all selected items.

Question

I want to take all rows that are selected and modify one column value in each of them.

I tried this but it doesn't work.

foreach (System.Data.DataRowView DRV in ItemDataGrid.SelectedItems)
{
    DRV.Row.BeginEdit();
    DRV.Row.ItemArray[6] = true;
    DRV.Row.EndEdit();
}

Anyone know how to do this?

Thanks, Matt

Don't try and edit the DataGridRow. Modify the objects bound to the grid instead. Then make a call to NotifyPropertyChanged that the collection the DataGrid is bound to has been updated.
