Question

我有以下查询来显示数据

Select 
     convert(varchar(10),SR.StockDate,103) as StockDate,SR.PartNo,
     SR.Openingbalance,SR.Received,SR.Issued,SR.Balance,SR.Entrytype,A.MaterialName 
from 
     StockRegister SR 
join LEDProducts A 
     on SR.PartNo=A.PartNo  
where 
     SR.LocationId='"+ ddl_Location.SelectedValue.ToString() + "' and A.AudioEntityId='" 
    + ddl_CountrySR.SelectedValue.ToString() + "' 
order by SR.Sno

它显示以下结果

 S Date       Type  ProductName   PartNo   OBalance  Receipt  Issues  CBalance
 1 26/07/2013  FTE     P16       01110101     500       0          0     500
 2 24/01/2014  EP      P16       01110101     500       0          100   400
 3 19/12/2013  FTE     P7        01110102     1000      0          0     1000

我需要显示如下产品名称：P16

Date            Type          Receipt  Issues    Balance
26/07/2013      FTE            500      0         500
24/01/2013       EP             0       100       400
Closing Balance :400

产品名称：P7

opening balance :1000
    Date            Type          Receipt  Issues    Balance
    26/07/2013      FTE            1000      0         1000

    Closing Balance :1000

就像我想要动态显示所有产品一样。

您可以使用转发器控件在

中使用DataGrid Control执行此操作

设置其数据源属性也可以在转发器中设置ItemTemplate，以便为每个产品显示任何控件

<asp:Repeater ID="Repeater1" runat="server">
    <ItemTemplate>
        <asp:GridView ID="GridView1" runat="server" DataSourceID="SqlDataSource1" EnableModelValidation="True"></asp:GridView>
        <asp:SqlDataSource runat="server" ID="SqlDataSource1"></asp:SqlDataSource>
    </ItemTemplate>
</asp:Repeater>

您可以使用任务面板设置要显示的列 configure the datagrid control using GUI tasks panel
