关于SqlDataSource控件中的ControlParameter的问题

Question

具体代码如下 <asp:SqlDataSource        id="srcEmployeeDetails"        ConnectionString="<%$ ConnectionStrings:Employees %>"        SelectCommand="SELECT * FROM Employees            WHERE FirstName=@FirstName AND LastName=@LastName"        Runat="server">        <SelectParameters>        <asp:ControlParameter            Name="FirstName"            ControlID="grdEmployees"            PropertyName='SelectedDataKey("FirstName")' />           <asp:ControlParameter            Name="LastName"            ControlID="grdEmployees"            PropertyName='SelectedDataKey("LastName")' />           </SelectParameters>     </asp:SqlDataSource>  貌似是PropertyName='SelectedDataKey("FirstName")'这个地方用()和[]都没有错误,这是为什么呢?这个地方应该是个索引器,索引器不是应该用中括号么?

你应该还有一个gridview的吧
