目前的代码如下
      <ItemTemplate>   
                        <asp:Label ID="lbgb05" runat="server"  Text='<%#Eval("gb05")%>' Visible="False"></asp:Label>          
                        <asp:DropDownList ID="DropDownList2" runat="server" DataSource="<%# Bindgb05() %>"  DataValueField="no" DataTextField="cinvcname">                      
                        </asp:DropDownList>                                                      
              </ItemTemplate>                                 
             </asp:TemplateField>

但是只显示Bindgb05() 的items的值,无法显示Eval("gb05")的值, 其中Bindgb05()代码如下
  public DataView Bindgb05()
    {
        DataTable dt = scanapmdt();       
        DataView dv2 = new DataView(dt);
        dv2.RowFilter = ("parentcode='3040'");        
        return dv2;
    }
我希望能达到要求是 Gridview1 每行 DropDownList2 控件 默认第一项的值是 Eval("gb05"), 其它行显示dv2,以方便用户选择,如何能做到呢
