SilverLight实现自动行号

首先看效果



思路：

在每个datagrid的第一列加上一个模板列，里面只定义一个textblock

之后在datagrid的行加载事件中，给每个行的textblock加上一个编号。

xaml代码：

 <data:DataGrid x:Name="gridList" Grid.Row="0" Margin="5,0,5,0"  GridLinesVisibility="All" 
                                   AutoGenerateColumns="False" 
                                    FrozenColumnCount="1" 
                                      AreRowDetailsFrozen="True"   
                       HorizontalAlignment="Stretch" CanUserSortColumns="False" 
                       ItemsSource="{Binding InvStockListModelList,Mode=TwoWay}" 
                       IsReadOnly="True" SelectedItem="{Binding InvStockListModel,Mode=TwoWay}">

                <data:DataGrid.Columns>
                <data:DataGridTemplateColumn Header="编号">
                    <data:DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <TextBlock />
                        </DataTemplate>
                    </data:DataGridTemplateColumn.CellTemplate>
                </data:DataGridTemplateColumn>
                <data:DataGridTextColumn Header="物料名称" Binding="{Binding MaterialModel.Mat_Name,Mode=TwoWay}"/>
                    <data:DataGridTextColumn Header="仓库名称" Binding="{Binding StorgeModel.Storge_Name,Mode=TwoWay}"/>

                    <data:DataGridTextColumn Header="库位名称" Binding="{Binding InvLocationModel.Location_Name,Mode=TwoWay}"/>
                    <data:DataGridTextColumn Header="批号" Binding="{Binding StockList_Batch,Mode=TwoWay}"/>
                    <data:DataGridTextColumn Header="年度" Binding="{Binding StockList_Year,Mode=TwoWay}"/>
                    <data:DataGridTextColumn Header="会计期间" Binding="{Binding StockList_Period,Mode=TwoWay}"/>
                    <data:DataGridTextColumn Header="收入数量" Binding="{Binding StockList_IAmount,Mode=TwoWay}"/>
                    <data:DataGridTextColumn Header="收入单价" Binding="{Binding StockList_IPrice,Mode=TwoWay}"/>
                    <data:DataGridTextColumn Header="收入金额" Binding="{Binding StockList_IMoney,Mode=TwoWay}" Width="100"/>
                    <data:DataGridTextColumn Header="发出数量" Binding="{Binding StockList_OAmount,Mode=TwoWay}"/>
                    <data:DataGridTextColumn Header="发出单价" Binding="{Binding StockList_OPrice,Mode=TwoWay}"/>
                    <data:DataGridTextColumn Header="发出金额" Binding="{Binding StockList_OMoney,Mode=TwoWay}" Width="100"/>
                    <data:DataGridTextColumn Header="期末数量" Binding="{Binding StockList_EndAmount,Mode=TwoWay}"/>
                    <data:DataGridTextColumn Header="期末金额" Binding="{Binding StockList_EndMoney,Mode=TwoWay}" Width="100"/>
                    <data:DataGridTextColumn Header="供应商批号" Binding="{Binding StockList_SuppBatch,Mode=TwoWay}"/>
                </data:DataGrid.Columns>
            </data:DataGrid>

cs代码：

public InvStockListView()
        {
            InitializeComponent();
            gridList.LoadingRow += new EventHandler<DataGridRowEventArgs>(gridList_LoadingRow);
        }
 void gridList_LoadingRow(object sender, DataGridRowEventArgs e)
        {
            var index = e.Row.GetIndex();
            var cell = gridList.Columns[0].GetCellContent(e.Row) as TextBlock;
            if (cell != null) cell.Text = (index + 1).ToString();
        }

大功告成！！！
