为什么数据未绑定到我的 WPF 应用程序中的标签 [英] Why data is not bound to label in my WPF application

问题描述

我正在WPF 中做一个简单的DataBinding 应用程序.在这个应用程序中，无论我在名为 txtName 的 TextBox 中输入什么，都应该出现在 Label 中.为此，我在 WPF 中使用了绑定，但它没有被绑定.

I am doing a simple DataBinding application in WPF. In this app whatever I type in a TextBox named txtName, should appear in the Label. For this purpose I used binding in WPF, but its not getting bound.

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="315*" />
        <ColumnDefinition Width="188*" />
    </Grid.ColumnDefinitions>

    <TextBox Height="23" HorizontalAlignment="Left"
             Margin="79,12,0,0" Name="txtName"
             VerticalAlignment="Top" Width="120" />
    <Label Height="28" HorizontalAlignment="Left"
             Margin="22,12,0,0" Name="label1"
             VerticalAlignment="Top" Width="42"
             Content="Name"/>
    <TextBox Height="23" HorizontalAlignment="Left"
             Margin="79,56,0,0" Name="txtSirName"
             VerticalAlignment="Top" Width="120" />
    <Label Content="SirName" Height="28"
           HorizontalAlignment="Left" Margin="12,56,0,0"
           Name="label2" VerticalAlignment="Top" Width="52" />
    
    <!-- Following is the label which I bound -->

    <Label Content="{Binding ElementName=txtName,Path=text}"
           Height="28" HorizontalAlignment="Left" Margin="47,112,0,0"
           Name="label3" VerticalAlignment="Top" Width="171" />
</Grid>

我是 WPF 的新手.请指导我.

推荐答案

很确定 XAML 区分大小写.您的绑定路径是 text，而它应该是 Text.

Pretty sure XAML is case sensitive. Your binding path is text when it should be Text.
