一般我們要實現居中設定 HorizontalContentAlignment="Center" VerticalContentAlignment="Center"就可以了， 但是datagrid的DataGridTextColumn中卻發現沒有HorizontalContentAlignment或者HorizontalAlignment，列中的內容仍然是左對齊，如何處理才能居中呢？

// 右對齊風格
Style styleRight = new Style(typeof(TextBlock));
Setter setRight = new Setter(TextBlock.HorizontalAlignmentProperty, HorizontalAlignment.Right);styleRight.Setters.Add(setRight);
foreach (DataGridColumn c in yourDataGrid.Columns)
{        DataGridTextColumn tc = c as DataGridTextColumn;
        if (tc != null)        
        {
                tc.ElementStyle = styleRight;
        }
}
 

即只要設定DataGridColumn的ElementStyle就可以了，也可以在xaml中設定

<Style x:Key="contentCenterStyle"
               TargetType="{x:Type TextBlock}">
            <Setter Property="HorizontalAlignment"
                    Value="Center" />
        </Style>

<DataGridTextColumn Header="程式碼"
            ElementStyle="{StaticResource contentCenterStyle}"
            Binding="{Binding Name}"></DataGridTextColumn>
