我正在与Oracle 10.2.0.4集成的ASP.net 4.0

这是我的GridView及其SqlDatasource代码

<asp:GridView ID="gvRegNumber" runat="server" AutoGenerateColumns="False" DataSourceID="DsRegNumberGrid"
            Width="100%" AllowPaging="True" BackColor="#CCCCCC" BorderColor="#999999" BorderStyle="Solid"
            BorderWidth="3px" CellSpacing="2" ForeColor="Black" PageSize="3" 
            CssClass="mGrid" onrowcommand="gvRegNumber_RowCommand" >
            <Columns>
                <asp:BoundField DataField="Registration No." HeaderText="Registration No." SortExpression="Registration No." />
                <asp:BoundField DataField="Name" HeaderText="Name" SortExpression="Name" />
                <asp:BoundField DataField="Make" HeaderText="Make" SortExpression="Make" />
                <asp:BoundField DataField="Model" HeaderText="Model" SortExpression="Model" />
                <asp:BoundField DataField="Status" HeaderText="Status" SortExpression="Status" />
                <asp:BoundField DataField="From Date" HeaderText="From Date" SortExpression="From Date" />
                <asp:BoundField DataField="To Date" HeaderText="To Date" SortExpression="To Date" />
                         <asp:TemplateField>
                <EditItemTemplate>
                    <asp:ImageButton ID="imgbtnUpdate" CommandName="Update" runat="server" ImageUrl="~/Themes/Icons/edit_icon.png"
                        ToolTip="Update" Height="20px" Width="20px" />
                </EditItemTemplate>
                <HeaderTemplate>
                    <asp:Label ID="Edit" Text="Edit" runat="server"></asp:Label>
                </HeaderTemplate>
                <ItemTemplate>
                    <asp:ImageButton ID="EditRow" CssClass="mGrid-edit" ImageUrl="~/Themes/Icons/edit_icon.png"
                        runat="server" />
                </ItemTemplate>
            </asp:TemplateField>
            <asp:TemplateField>
                <HeaderTemplate>
                    <asp:Label ID="Delete" Text="Edit" runat="server"></asp:Label>
                </HeaderTemplate>
                <ItemTemplate>
                    <asp:ImageButton ID="DeleteRow" CssClass="mGrid-delete" ImageUrl="~/Themes/Icons/delete_icon.png"
                        runat="server" />
                </ItemTemplate>
            </asp:TemplateField>
            </Columns>

        </asp:GridView>
        <asp:SqlDataSource ID="DsRegNumberGrid" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
            ProviderName="<%$ ConnectionStrings:ConnectionString.ProviderName %>" SelectCommand="SELECT &quot;fkEnumerationId&quot; AS &quot;Registration No.&quot;, &quot;Text&quot; AS &quot;Name&quot;, &quot;AdditionalValueText&quot; AS &quot;Make&quot;, &quot;AdditionalValue&quot; AS &quot;Model&quot;, &quot;IsActive&quot; AS &quot;Status&quot;, &quot;CreatedOn&quot; AS &quot;From Date&quot;, &quot;LastUpdatedOn&quot; AS &quot

;To Date&quot; FROM &quot;EnumerationValue&quot;">
    </asp:SqlDataSource>

我只想为网格中的单独列提供单独的数据源。那可能吗？如果是这样，怎么办？

提前致谢。

你可以在你的SP中做到这一点

select en1.text as 'Country', en2.text as 'City',en3.text as 'Region'  from
EnumValue en1, EnumValue en2, EnumValue en3
where en1.id = en2.[fkEnumeration] and en3.[fkEnumeration] = en2.id  and 
en1.id='yourid' ;
