ID键没有显示在列表视图了 [英] id key not showing up in listview

问题描述

我想在我的列表视图显示DoctorId关键领域，它总是会说出空白。

I am trying to display the DoctorId key field in my listview and it's coming out always with blanks.

下面是.aspx页

       <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>

所有领域都走出来，除了doctorID正确的价值观。

All the fields are coming out with the proper values EXCEPT the doctorID.

下面是我的Appointement.designer.cs

Here is my 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;

医生的名字叫出来，因此以某种方式连接正确。我不明白为什么没有被显示在列表视图的doctorId或Doctor.Id。

The doctor Name is coming out so it is somehow connected properly. I don't see why the doctorId or the Doctor.Id is not been displayed on the Listview.

下面是Appointement.dbml是如何定义：
Appointement表（aptId，客户端ID，doctorId，dateApt，hourApt，IsAvailable）
医生表（ID，doctor_name）

Here is how the Appointement.dbml is define: Appointement Table (aptId,clientId,doctorId,dateApt,hourApt,IsAvailable) Doctor Table (Id,doctor_name)

我注意到了我的Appointement.aspx列DoctorId没有显示与数据绑定起来的设计模式。关于如何使用数据绑定有任何想法？

I noticed in the Design mode for the Appointement.aspx my column DoctorId is not showing up with DataBound. any idea on how to have it with DataBound ?

感谢

推荐答案

不知何故，我不知道为什么我删除表TD定义

somehow I don't know why I deleted the table td definition

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

和我搬到他们在定义的末尾和它的作品！

and I moved them at the end of the definition and it works !!!

如果它可以帮助其他人在未来...
