wp7的ListBox绑定数据错误

Question

I am trying to use a collection of checkboxes (created in runtime) within a ListBox. The XAML I am writing is

<ListBox DataContext="{Binding}" Name="cuisineList">
               <ListBox.ItemTemplate>
                    <DataTemplate>

                        <Grid Height="45" Name="grid1" Margin="0,0,0,0">
                                <Grid.ColumnDefinitions>
                                    <ColumnDefinition Width="230*" />
                                    <ColumnDefinition Width="230*" />
                                </Grid.ColumnDefinitions>
                            <CheckBox Content="{Binding content}" Name="{Binding name}" Grid.Column="0"/>
                            <CheckBox Content="{Binding content}" Name="{Binding name}" Grid.Column="1"/>
                        </Grid>

                    </DataTemplate>
        </ListBox.ItemTemplate>
</ListBox>

and the code is

public ObservableCollection<Cuisine> Items = new ObservableCollection<Cuisine>();
    public Search()
    {
        InitializeComponent();
        for (int i = 0; i < 100; i++)
        {
            Items.Add(new Cuisine());
        }
        cuisineList.DataContext = Items;
    }

But when I run my app, I don't see any check box. Please point out the mistake and help me rectify it. Thanks in advance!

Answer 1

You need to set the itemsource of the listbox as follows

<ListBox ItemsSource="{Binding Items}" Name="cuisineList">

                    <Grid Height="45" Name="grid1" Margin="0,0,0,0">
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition Width="230*" />
                                <ColumnDefinition Width="230*" />
                            </Grid.ColumnDefinitions>
                        <CheckBox Content="{Binding content}" Name="Check1" Grid.Column="0"/>
                        <CheckBox Content="{Binding content}" Name="Check2" Grid.Column="1"/>
                    </Grid>

                </DataTemplate>
    </ListBox.ItemTemplate>

Also is there any restriction to write Items in *.xaml.cs file ??

If not write in a view model say PageViewModel.cs file

then Set Viewmodel class object as page.xaml data context. (

this.DataContext = new PageViewModel();

Write the this statement in the constructor of Page.xaml.cs file)

Also verify that the Cuisine has public property Content

您需要在列表框上设置项目来源。

<ListBox ItemsSource="{Binding}" Name="cuisineList">
