Question

我用C＃代码创建Textblocks，我想将JSON数据绑定到它。此刻我想这样做：

        if (actualStock == true)
        {
            TextBlock TBActualStock = new TextBlock();
            TBActualStock.Text = "Actuele voorraad: ";
            TBActualStock.FontSize = 18;
            STACKActualStockDeliverTime.Children.Insert(1, TBActualStock);

            TextBlock TBBindActualStock = new TextBlock();
            TBBindActualStock.Text = "{Binding ActualStock}"; //this is where it should bind
            TBBindActualStock.FontSize = 18;
            STACKActualStockDeliverTime2.Children.Insert(1, TBBindActualStock);
        }

这是我的XAML代码：

 DataContext="{Binding Item}"
    d:DataContext="{Binding Groups[0].Items[0]}">
    <Grid.ChildrenTransitions>
        <TransitionCollection>
            <EntranceThemeTransition/>
        </TransitionCollection>
    </Grid.ChildrenTransitions>
    <Grid.RowDefinitions>
        <RowDefinition Height="140"/>
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>
    <Grid.Background>
        <ImageBrush ImageSource="/Assets/BackGroundGAC.jpg" Stretch="UniformToFill"/>
    </Grid.Background>

    <Grid Grid.Row="1" x:Name="contentRegion">
        <StackPanel Orientation="Horizontal">
                <StackPanel Orientation="Horizontal">
                    <StackPanel x:Name="STACKActualStockDeliverTime">
                        <TextBlock x:Name="HEADERActualStockDeliverTime" FontSize="24" Text="Voorraad en levertijd"></TextBlock>     
                    </StackPanel>

                    <StackPanel  x:Name="STACKActualStockDeliverTime2">
                        <TextBlock x:Name="Headert" FontSize="24" Text=""></TextBlock>


                    </StackPanel>
                </StackPanel>

现在我想将Json数据添加到我在C＃代码中创建的文本块中。我知道在XAML中我应该使用{Binding description} //description is a part of my json object so that works但是如果我在C＃代码中这样做，它只会将文本设置为{Binding Description}

知道如何解决这个问题吗？

ps：我需要用C＃代码而不是XAML代码。

Answer 1

如果您在代码中绑定，则不应该这样做，只需指定值

即可

TextBlock.Text Property

    TextBlock TBBindActualStock = new TextBlock();
    TBBindActualStock.Text =  ActualStock ;

如果要在代码中绑定，请使用“绑定操作”，

Binding binding = new Binding();
binding.Path = new PropertyPath("ActualStock");
binding.Source = sourceObject; 

BindingOperations.SetBinding(TBBindActualStock, TextBlock.TextProperty, binding);

来自Binding String Property in Code-Behind TextBlock

在XAML中，

    <TextBlock Text="{Binding ActualStock}

你可以像这样使用Binding类

Binding myBinding = new Binding("ActualStock");
myBinding.Source = myDataObject;//here is your data source.
TBBindActualStock.SetBinding(TextBlock.TextProperty, myBinding);

通过C＃代码将Json数据绑定到TextBlock
