WPF Datagrid progress bar cell

Hi all of you,

My goal is be to able to define maximum value for my progressbar cell depending on other value in the same row:

"Maximum" value should be connected with "Stock_max" sql field instead of to have a hardcoded value..

How can I achieve that?

<DataGridTextColumn Header="Mínimo" Width="100" 
Binding="{Binding Stock_min}"/><DataGridTextColumn Header="Máximo" Width="100" 
Binding="{Binding Stock_max}"/><DataGridTemplateColumn Header="Actual" 
Width="80" Visibility="Visible"><DataGridTemplateColumn.CellTemplate><DataTemplate><ProgressBar 
Value="{Binding Path=Stock_Actual, Mode=OneWay}" 
Minimum="0" Maximum="20" /></DataTemplate></DataGridTemplateColumn.CellTemplate></DataGridTemplateColumn>
