TextTrimming is what you are looking for. Use the DataGridTemplateColumn and insert a TextBlock into the CellTemplate which supports TextTrimming. Sample -

<DataGrid ItemsSource="{Binding ItemsSourceForYourGrid}">
   <DataGrid.Columns>
      <DataGridTemplateColumn Width="20">
         <DataGridTemplateColumn.CellTemplate>
            <DataTemplate>
              <TextBlock Text="{Binding Name}" TextTrimming="CharacterEllipsis"/>
            </DataTemplate>
         </DataGridTemplateColumn.CellTemplate>
      </DataGridTemplateColumn>
    </DataGrid.Columns>
</DataGrid>
