Unable to change DataRow value

I bound a datatable to a datagrid. Now I would like to change the datatable’s value corresponding to the row of the selected cell once a button is clicked. Here is my code:

    private void BtnModifyColorBlue_Click(object sender, RoutedEventArgs e)
    {
        if (dataGrid.SelectedCells.Count < 1)
            return;
        DataGridCellInfo dc = dataGrid.SelectedCells.FirstOrDefault();
        DataRowView drv = dc.Item as DataRowView;
        if (drv == null)
            return;
        drv.Row.ItemArray[11] = Brushes.Blue;
    }                                                                                      

For some reason, after the assignment, the datatable’s value is untouched. Are there any mysterious things happening here? BTW, I can conform that the assignment has been executed. Thanks a lot.

You can’t change through the item array, use the syntax below:

drv.Row[11] = Brushes.Blue;
