Get RichTextBox from DataGrid when cells are RichTextBox

I override my DataGrid to use RichTextBox as DataGridTemplateColumn. Now in code behind I want to have access to these RichTexBoxes from the grid. For example I want to get the RichTextBox of row 10 column 1. How can I do that?

<DataGridTemplateColumn Header="First Language" IsReadOnly="False" Width="*">
    <DataGridTemplateColumn.CellTemplate>
         <DataTemplate>
              RichTextBox>
                   <FlowDocument IsOptimalParagraphEnabled="True" IsHyphenationEnabled="True">
                     <Paragraph FontFamily="Segoe UI" FontSize="14 ">
                           <Run Text="{Binding Path=First ,Mode=TwoWay , UpdateSourceTrigger=PropertyChanged}" />
                      </Paragraph>
                   </FlowDocument>
              </RichTextBox>
          </DataTemplate>
     </DataGridTemplateColumn.CellTemplate>
 </DataGridTemplateColumn>

UPDATE:

with the code I find below I was able to get DataGridCell, but casting the the content as RichTextBox gives me null. Any ideas?

Try this:

int row = 0;
int column = 0;
DataGridCell cell = Datagrid.GetCell(dataGrid, row, column);
ContentPresenter cp = cell.Content as ContentPresenter;
if (VisualTreeHelper.GetChildrenCount(cp) > 0)
{
    RichTextBox rtb = VisualTreeHelper.GetChild(cp, 0) as RichTextBox;
}
