GridView增加自动序号列

第一种方式,直接在Aspx页面GridView模板列中.这种的缺点是到第二页分页时又重新开始了.

1. <asp:TemplateFieldHeaderText="序号"InsertVisible="False">
2. <ItemStyleHorizontalAlign="Center"/>
3. <HeaderStyleHorizontalAlign="Center"Width="5%"/>
4. <ItemTemplate>
5. <%#Container.DataItemIndex+1%>
6. </ItemTemplate>
7. </asp:TemplateField>

第二种方式分页时进行了计算,这样会累计向下加.

1. <asp:TemplateFieldHeaderText="序号"InsertVisible="False">
2. <ItemStyleHorizontalAlign="Center"/>
3. <HeaderStyleHorizontalAlign="Center"Width="5%"/>
4. <ItemTemplate>
5. <asp:LabelID="Label2"runat="server"Text='<%#this.MyListGridView.PageIndex*this.MyListGridView.PageSize+this.MyListGridView.Rows.Count+1%>'/>
6. </ItemTemplate>
7. </asp:TemplateField>

还有一种方式放在cs代码中,和第二种相似.

1. <asp:BoundFieldHeaderText="序号">
2. <ItemStyleHorizontalAlign="Center"/>
3. <HeaderStyleHorizontalAlign="Center"Width="5%"/>
4. </asp:BoundField>
7. protectedvoidmyGridView_RowDataBound(objectsender,GridViewRowEventArgse)
8. {
9. if(e.Row.RowIndex!=-1)
10. {
11. intindexID=this.myGridView.PageIndex*this.myGridView.PageSize+e.Row.RowIndex+1;
12. e.Row.Cells[0].Text=indexID.ToString();
13. }
14. }
