使用ElementStyle

<Grid>
    <Grid.Resources>
        <Style x:Key="TextBlockStyleKey" TargetType="{x:Type TextBlock}">
            <Setter Property="TextTrimming" Value="CharacterEllipsis"/>
        </Style>
    </Grid.Resources>

    <DataGrid AutoGenerateColumns="False" ItemsSource="{Binding Items}">
        <DataGrid.Columns>
            <DataGridTextColumn ElementStyle="{StaticResource TextBlockStyleKey}" Header="Name" Binding="{Binding Name}"/>
        </DataGrid.Columns>
    </DataGrid>
</Grid>

结果：
