Answer 2

你就多绑定一个属性，例如
<asp:TextBox ID="txtReality" runat="server" CssClass="text_input" TextMode="MultiLine"
  Height="50px" Text='<%#Eval("Reality") %>' ToolTip='<%#Eval("你实际绑定的") %>'></asp:TextBox>然后后台获取实际的值就行了

Answer 3

<%# (Eval("Reality")==null || Eval("Reality")=="")?Eval("BeginPlanDate").ToString().Trim():Eval("Reality") %>

Answer 4

首先谢谢大家，你这样不行的，因为两个值都会被作为实际的值，我已经解决了。如下：<asp:TemplateField HeaderText="实际执行" HeaderStyle-Width="10%">
                                                    <ItemTemplate>
                                                        <asp:TextBox ID="txtReality" runat="server" CssClass="text_input" TextMode="MultiLine"
                                                            Height="50px" Text='<%#Eval("Reality").ToString().Trim()==""?Eval("Executor").ToString().Trim():Eval("Reality").ToString().Trim() %>'></asp:TextBox>
                                                    </ItemTemplate>
                                                </asp:TemplateField>

Answer 5

<%#Eval("Reality").ToString().Trim()==""?为NULL就报错
