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

如果您不想使用DatagridTemplateColumn,则可以更改DataGridTextColumn.EditingElementStyle并在那里设置TextBox.MaxLength:

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