将某些代码移至服务器时遇到问题。代码在我的本地机器上运行良好。我在本地机器上访问这个属性没有问题。但是，当我将它上传到我的开发服务器时，我收到了这个错误：

在所选数据源上找不到名为“CreatedBy.FullName”的字段或属性。

说明：执行当前 Web 请求期间发生未处理的异常。请查看堆栈跟踪以获取有关错误及其源自代码的位置的更多信息。

异常详细信息：System.Web.HttpException：在所选数据源上找不到名为“CreatedBy.FullName”的字段或属性。源错误：

在执行当前 Web 请求期间生成了未处理的异常。可以使用下面的异常堆栈跟踪来识别有关异常起源和位置的信息。

这是 aspx 页面的样子（截图）：

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="ObjectDataSource1" DataKeyNames="ApplicationID" CellPadding="4" ForeColor="#333333" GridLines="None">
        <AlternatingRowStyle BackColor="White" ForeColor="#284775" />
        <Columns>
            <asp:CommandField ShowEditButton="True" ShowDeleteButton="True" />
            <asp:HyperLinkField DataNavigateUrlFields="applicationID" DataNavigateUrlFormatString="~/Admin/ManageRoles.aspx?applicationID={0}" Text="View App Roles" />
            <asp:HyperLinkField DataNavigateUrlFields="applicationID" DataNavigateUrlFormatString="~/Admin/ManageApplicationUsers.aspx?applicationID={0}" Text="View App Users" />
            <asp:BoundField DataField="ApplicationID" HeaderText="ApplicationID" ReadOnly="True" SortExpression="ApplicationID" />
            <asp:BoundField DataField="Name" HeaderText="Name" SortExpression="Name" />
            <asp:TemplateField HeaderText="Description" SortExpression="Description">
                <EditItemTemplate>
                    <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("Description") %>' TextMode="MultiLine"></asp:TextBox>
                </EditItemTemplate>
                <ItemTemplate>
                    <asp:Label ID="Label1" runat="server" Text='<%# Bind("Description") %>'></asp:Label>
                </ItemTemplate>
            </asp:TemplateField>
            <asp:BoundField DataField="CreatedBy.FullName" HeaderText="Created By" SortExpression="CreatedByID" ReadOnly="True" />
            <asp:BoundField DataField="CreatedDate" HeaderText="CreatedDate" ReadOnly="True" SortExpression="CreatedDate" />
            <asp:BoundField DataField="ModifiedBy.FullName" HeaderText="Modified By" SortExpression="ModifiedByID" NullDisplayText="&lt;i&gt;null&lt;/i&gt;" ReadOnly="True" />
            <asp:BoundField DataField="ModifiedDate" HeaderText="ModifiedDate" ReadOnly="True" SortExpression="ModifiedDate" NullDisplayText="&lt;i&gt;null&lt;/i&gt;" />
        </Columns>
<!-- SNIP: styling -->
</asp:GridView>

更新 我已经通过使用一种解决方法来运行我的代码。如果我使用模板字段而不是绑定字段，它将运行。例如，我使用这个：

<asp:TemplateField HeaderText="Description" SortExpression="Description">
                <EditItemTemplate>
                    <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("CreatedBy.FullName") %>' TextMode="MultiLine"></asp:TextBox>
                </EditItemTemplate>
                <ItemTemplate>
                    <asp:Label ID="Label1" runat="server" Text='<%# Bind("CreatedBy.FullName") %>'></asp:Label>
                </ItemTemplate>
            </asp:TemplateField>

而不是这个：

<asp:BoundField DataField="CreatedBy.FullName" HeaderText="Created By" SortExpression="CreatedByID" ReadOnly="True" />

我很高兴它现在可以工作，但坦率地说，我也想知道问题所在！

你的问题的答案是这样的：

ABoundField显示来自您datasource的文本的信息，并且TemplateField允许混合使用HTML,WebControls和data-binding语法。
