废话不多数，先上效果图和代码：

<dxg:GridControl.View>
<dxg:TableView x:Name="tbv"/>

使用
<local:UCGridControl x:Name="gc">
<dxg:GridControl.Columns>
<dxg:GridColumn FieldName="Name" Header="Name"/>
</dxg:GridControl.Columns>
</local:UCGridControl> var list = new List<object>();
for (int i = 0; i <; i++)
{
list.Add(new { Name="test"+(i+1)});
}
gc.ItemsSource = list;
gc.ShowOrderNum = Visibility.Visible;
主要代码是重新设置TableView的行标题模板：
<DataTemplate x:Key="DataTemplate1">
<Border x:Name="errorIndicatorBorder" Background="Transparent">
<Grid>
<TextBlock x:Name="txtOrderNum" TextAlignment="Center" Text="{Binding RowHandle,Converter={StaticResource RowOrderNumConverter}}" Visibility="{Binding ShowOrderNum, ElementName=uc}" />
......
var dt = this.FindResource("DataTemplate1") as DataTemplate;
if (dt != null)
tbv.RowIndicatorContentTemplate = dt;
绑定的RowHandle属性包含行索引，使用个转换器加1就可以转换成序号了。
