How to limit WPF DataGridTextColum Text max length to 10 characters

Question

How can I limit WPF DataGridTextColumn Text to max length of 10 characters.

I don't want to use DatagridTemplateColumn, because it has memory leak problems.

Also the field is bound to a data entity model.

If you don't want to use DatagridTemplateColumn then you can change DataGridTextColumn.EditingElementStyle and set TextBox.MaxLength there:

<DataGridTextColumn Binding="{Binding Path=SellingPrice, UpdateSourceTrigger=PropertyChanged}">
   <DataGridTextColumn.EditingElementStyle>
      <Style TargetType="{x:Type TextBox}">
         <Setter Property="MaxLength" Value="10"/>
      </Style>
   </DataGridTextColumn.EditingElementStyle>
</DataGridTextColumn>
