wpf應用程序的新手。我試圖執行這個代碼,但標籤總是空白不管我在文本框中輸入:爲什麼TextBox無法綁定到我的XAML代碼中的Label?
<Window x:Class="Mufu.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Muf(u)" Height="350" Width="525">
<Grid>
<TextBox Height="23" HorizontalAlignment="Left" Margin="100,200,0,0" Name="textBox3" VerticalAlignment="Top" Width="124" />
<Label Content="{Binding ElementName=textbox3, Path=Text}" Height="48" HorizontalAlignment="Center" Margin="0,30,0,0" Name="label4" VerticalAlignment="Top" Width="445" FontSize="26" />
</Grid>
嘆息......它始終是我的邏輯錯誤。非常感謝。 – Jaja 2014-10-19 00:55:36
