问 WPF -冻结WPF嵌套ListView中的第一项

EN

下面的示例展示了如何将结构转换为具有 GridView 的 ListView ，其中每一列都是一个医生。

假设源数据结构如下：

public class DoctorsVM
    public DoctorsVM()
        Doctors = new List<Doctor>();
    public ICollection<Doctor> Doctors { get; set; }
public class Doctor
    public Doctor()
        AppointmentDetails = new List<AppointmentDetail>();
    public string DoctorName { get; set; }
    public ICollection<AppointmentDetail> AppointmentDetails { get; set; }
public class AppointmentDetail
    public string PatientName { get; set; }
}

您可以创建以下转换：

public class DoctorAppointmentCollectionVM
    public DoctorAppointmentCollectionVM()
        Doctors = new List<Doctor>();
        Entries = new List<DoctorAppointmentLineItem>();
    public List<Doctor> Doctors { get; set; }
    public List<DoctorAppointmentLineItem> Entries { get; set; }
public class DoctorAppointmentLineItem
    public DoctorAppointmentLineItem()
        AppointmentLine = new List<AppointmentDetail>();
    public List<AppointmentDetail> AppointmentLine { get; set; }
public DoctorAppointmentCollectionVM DoctorsToLineCollection(DoctorsVM docs)
    var result = new DoctorAppointmentCollectionVM();
    for (int i = 0; i < docs.Doctors.Count; i++)
        var doc = docs.Doctors.ElementAt(i);
        result.Doctors.Add(doc);
        for (int j = 0; j < doc.AppointmentDetails.Count; j++)
            var appointment = doc.AppointmentDetails.ElementAt(j);
            DoctorAppointmentLineItem patientArray;
            if (j >= result.Entries.Count)
                patientArray = new DoctorAppointmentLineItem();
                patientArray.AppointmentLine.AddRange(Enumerable.Range(0, docs.Doctors.Count).Select(x => (AppointmentDetail)null));
                result.Entries.Add(patientArray);
                patientArray = result.Entries[j];
            patientArray.AppointmentLine[i] = appointment;
    return result;
}

并创建一个列表视图，如下所示：

<ListView x:Name="lv1" ItemsSource="{Binding Entries}" Loaded="lv1_Loaded">
    <ListView.View>
        <GridView x:Name="gv1">
        </GridView>
    </ListView.View>
</ListView>

为每个医生创建一个列

private void lv1_Loaded(object sender, RoutedEventArgs e)
    var data = lv1.DataContext as DoctorAppointmentCollectionVM;
    if (data != null)
        gv1.Columns.Clear();
        for (int i = 0; i < data.Doctors.Count; ++i)
            gv1.Columns.Add(new GridViewColumn
