Question

我是Windows Phone 7的新手。我想生成一个从其他页面注册的学生列表。我想将学生列表显示为网格记录

我的代码如下：

xaml代码：

<Grid VerticalAlignment="Top" HorizontalAlignment="Left" ShowGridLines="True" Width="400" Height="200" Name="GridStud">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="*" />
                    <ColumnDefinition Width="*" />
                    <ColumnDefinition Width="*" />
                    <ColumnDefinition Width="*" />
                    <ColumnDefinition Width="*" />
                    <ColumnDefinition Width="*" />
                </Grid.ColumnDefinitions>
                <Grid.RowDefinitions>
                    <RowDefinition Height="*" />
                    <RowDefinition Height="*" />
                    <RowDefinition Height="*" />
                    <RowDefinition Height="*" />
                    <RowDefinition Height="*" />
                    <RowDefinition />
                </Grid.RowDefinitions>

                <TextBlock FontSize="20" FontWeight="Bold" Grid.ColumnSpan="3" Grid.Row="0">Registered Student List</TextBlock>
                <TextBlock FontSize="12" FontWeight="Bold" Grid.Row="1" Grid.Column="0">Id</TextBlock>
                <TextBlock FontSize="12" FontWeight="Bold" Grid.Row="1" Grid.Column="1">Full Name</TextBlock>
                <TextBlock FontSize="12" FontWeight="Bold" Grid.Row="1" Grid.Column="2">Contact</TextBlock>
                <TextBlock FontSize="12" FontWeight="Bold" Grid.Row="1" Grid.Column="3">Email</TextBlock>
                <TextBlock FontSize="12" FontWeight="Bold" Grid.Row="1" Grid.Column="4">Stream</TextBlock>
                <TextBlock FontSize="12" FontWeight="Bold" Grid.Row="1" Grid.Column="5">Delete</TextBlock>

                <TextBlock Grid.Row="2" Grid.Column="0" Name="txtId" />
                <TextBlock Grid.Row="2" Grid.Column="1" Name="txtName" />
                <TextBlock Grid.Row="2" Grid.Column="2" Name="txtContact" />
                <TextBlock Grid.Row="2" Grid.Column="3" Name="txtEmail" />
                <TextBlock Grid.Row="2" Grid.Column="4" Name="txtStream" />
                <Button FontSize="12" FontWeight="Bold" Grid.Row="2" Grid.Column="5" Name="btnDelete">Delete</Button>

                <TextBlock FontSize="16" FontWeight="Bold" Grid.ColumnSpan="3" Grid.Row="4">Total Students: 3</TextBlock>

            </Grid>

CS代码：

private void PivotItem_Loaded(object sender, RoutedEventArgs e)
        {
            IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication();
            StreamReader sr = null;
            try
            {
                sr = new StreamReader(new IsolatedStorageFileStream("Data\\inquiry.json", FileMode.Open, isf));


                while (!sr.EndOfStream)
                {
                    var stud = JsonConvert.DeserializeObject<Student>(sr.ReadLine());

                    txtId.Text += "\t" + stud.Id;
                    txtName.Text += "\t" + stud.Name;
                    txtContact.Text += "\t" + stud.Contact;
                    txtEmail.Text += "\t" + stud.Email;
                    txtStream.Text += "\t" + stud.Stream;
                }

                sr.Close();

            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

显示所有已注册的记录，但是在一行中。我想在不同的行中显示这些记录，并生成运行时网格行。

Answer 1

 public ObservableCollection<StudentListModel> StudentListItems { get; private set; }

初始化ObservableCollection。并且您必须在StudentListModel类中指定字段。喜欢关注

  private long? _id;
        public long? Id
        {
            get
            {
                return _id;
            }
            set
            {
                if (value != _id)
                {
                    _id = value;
                    NotifyPropertyChanged("Id");
                }
            }
        }

在PhoneApplicationPage的构造函数中，您必须创建如下所示的StudentListItem

 public StudentList()
   {

    this.StudentListItems = new ObservableCollection<StudentListModel>();

    }

之后您必须将值分配给集合，如下所示。在这里，我从数据库中检索值。

 foreach (var dri in getStudentList)
                {
     this.StudentListItems.Add(new StudentListModel()
                            {
                                Id= dri.Id,
                                Name= dri.Name,
                                Contact= dri.Contact,
                                Email=  dri.Email,

                            });
}

你必须将它设置为Listbox。

viewStudentList.ItemsSource = StudentListItems;

您的观点应该如下。它给出了输出列表。

 <ListBox ItemsSource="{Binding}"   Name="viewStudentList" Grid.ColumnSpan="3" Margin="7,38,-7,-108" >
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <Grid Height="40">
                        <TextBlock Text="{Binding ID}" TextWrapping="Wrap"  Style="{StaticResource PhoneTextSubtleStyle}" Margin="0,0,290,-22" TextAlignment="Left" Foreground="{StaticResource PhoneForegroundBrush}"/>
                        <TextBlock Text="{Binding Name}" TextWrapping="Wrap" Foreground="{StaticResource PhoneForegroundBrush}"  Style="{StaticResource PhoneTextSubtleStyle}" Margin="60,0,138,-22" TextAlignment="Center"/>
                        <TextBlock Text="{Binding Contact}" TextWrapping="Wrap" Foreground="{StaticResource PhoneForegroundBrush}" Style="{StaticResource PhoneTextSubtleStyle}" Margin="150,0,12,-22" TextAlignment="Center"/>
                        <TextBlock Text="{Binding Email}" TextWrapping="Wrap" Foreground="{StaticResource PhoneForegroundBrush}" Style="{StaticResource PhoneTextSubtleStyle}" Margin="355,0,12,-22" TextAlignment="Right"/>
                    </Grid>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>

如何使用Windows Phone 7在运行时在网格中添加行？
