比如表中三个字段
key1 int,key2 int,item varchar(50)
前面2个字段联合主键
前台代码：
<asp:DataGrid id="DataGrid1" runat="server" AutoGenerateColumns="False" DataKeyField="DoubleKey">
<Columns>
<asp:BoundColumn DataField="item" HeaderText="item"></asp:BoundColumn>
<asp:ButtonColumn CommandName="del" Text="删除"></asp:ButtonColumn>
</Columns>
</asp:DataGrid>
<Columns>
<asp:BoundColumn DataField="item" HeaderText="item"></asp:BoundColumn>
<asp:ButtonColumn CommandName="del" Text="删除"></asp:ButtonColumn>
</Columns>
</asp:DataGrid>
