Question

我正在尝试在列表视图中显示DoctorId键字段，并且它总是以空格显示。

这是.aspx页面

       <asp:LinqDataSource ID="LinqDataSource1" runat="server" 
         ContextTypeName="AppointementDataContext" EnableDelete="True" EnableInsert="True" 
         EnableUpdate="True" EntityTypeName="" TableName="Appointement" 
            Where="IsAvailable = True && dateApt >= DateTime.Now && doctorId = Doctor.Id &&
                   doctorid = 1"> 

            <WhereParameters>
               <asp:ControlParameter 
                   Name="doctor_name" 
                   ControlID="DropDownList1" 
                   PropertyName="SelectedValue"
                   Type="String" />
             </WhereParameters>

        </asp:LinqDataSource>

       <asp:ListView ID="ListView1" runat="server" DataKeyNames="aptId" 
         DataSourceID="LinqDataSource1" InsertItemPosition="LastItem" >
            <AlternatingItemTemplate>
                <tr style="">
                  <td>
                    <asp:Label ID="lblDoctorId" runat="server" Value='<%# Eval("doctorId") %>' />
                  </td>
                  <td>
                    <asp:Label ID="DoctorNameLabel" runat="server" 
                          Text='<%# Eval("Doctor.Doctor_Name") %>' />
                  </td>
                  <td>
                     <asp:Label ID="dateAptLabel" runat="server" 
                          Text='<%# Eval("dateApt", "{0:dd/MM/yyyy}") %>' />
                  </td>
                  <td>
                    <asp:Label ID="hourAptLabel" runat="server" 
                        Text='<%# Eval("hourApt", @"{0:hh\:mm}") %>' />
                  </td>

                  <td>
                    <asp:CheckBox id="MyCheckBox" runat="server"
                         value='<%# Eval("aptId") %>'
                         AutoPostBack="true"
                         OnCheckedChanged="Check_Clicked" />
                 </td>
                </tr>
            </AlternatingItemTemplate>

            <ItemTemplate>
                <tr style="">
                  <td>
                    <asp:Label ID="lblDoctorId" runat="server" Value='<%# Eval("doctorId") %>' />
                  </td>
                  <td>
                    <asp:Label ID="DoctorNameLabel" runat="server" 
                          Text='<%# Eval("Doctor.Doctor_Name") %>' />
                  </td>
                  <td>
                     <asp:Label ID="dateAptLabel" runat="server" 
                          Text='<%# Eval("dateApt", "{0:dd/MM/yyyy}") %>' />
                  </td>
                  <td>
                    <asp:Label ID="hourAptLabel" runat="server" 
                        Text='<%# Eval("hourApt", @"{0:hh\:mm}") %>' />
                  </td>

                  <td>
                    <asp:CheckBox id="MyCheckBox" runat="server"
                         value='<%# Eval("aptId") %>'
                         AutoPostBack="true"
                         OnCheckedChanged="Check_Clicked" />
                 </td>
                </tr>
            </ItemTemplatee>

所有字段都以适当的值出现，除了doctorID。

这是我的Appointement.designer.cs

 public partial class Doctor : INotifyPropertyChanging, INotifyPropertyChanged
 {

private static PropertyChangingEventArgs emptyChangingEventArgs = new 
        PropertyChangingEventArgs(String.Empty);

private int _Id;

private string _Doctor_name;

private EntitySet<Appointement> _Appointement;



 public partial class Appointement : INotifyPropertyChanging, INotifyPropertyChanged
 {

private static PropertyChangingEventArgs emptyChangingEventArgs = new 
             PropertyChangingEventArgs(String.Empty);

private int _aptId;

private System.Nullable<int> _clientId;

private int _doctorId;

private System.DateTime _dateApt;

private System.TimeSpan _hourApt;

private System.Nullable<bool> _IsAvailable;

private EntityRef<Doctor> _Doctor;

医生名字出来所以它以某种方式正确连接。我不明白为什么在Listview上没有显示doctorId或Doctor.Id。

以下是Appointement.dbml的定义方式： Appointement表（aptId，clientId，doctorId，dateApt，hourApt，IsAvailable）医生表（Id，doctor_name）

我注意到在Appointement.aspx的设计模式下，我的专栏DoctorId没有显示DataBound。关于如何使用DataBound的任何想法？

由于

Answer 1

不知怎的，我不知道为什么我删除了表td定义

     <asp:Label ID="lblDoctorId" runat="server" Value='<%# Eval("doctorId") %>' />

我在定义的最后移动它们并且它有效！

如果它可以在将来帮助其他人......

id键未显示在列表视图中
