主窗口依賴屬性格式綁定問題
<Window x:Class="dep2.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:dep2"
Title="Window1" Height="300" Width="381">
<Grid>
<local:UserControl1></local:UserControl1>
<Button Height="23" HorizontalAlignment="Right" Margin="0,0,77,36" Name="button1" VerticalAlignment="Bottom" Width="75" Click="button1_Click">Button</Button>
</Grid>
</Window>
public partial class Window1 : Window
{
UserControl1 uc = new UserControl1();
public Window1()
{
InitializeComponent();
}
private void button1_Click(object sender, RoutedEventArgs e)
{
uc.InfoText = "SAMPLE";
}
}
我的用戶控件
<UserControl x:Class="dep2.UserControl1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Height="32" Width="300">
<Grid Height="30">
<StackPanel Background="LightCyan">
<TextBox Height="21" Name="textBlock1" Width="120" Text="{Binding Text}" />
</StackPanel>
</Grid>
</UserControl>
public partial class UserControl1 : UserControl
{
public string InfoText
{
get
{
return (string)GetValue(InfoTextProperty);
}
set
{
SetValue(InfoTextProperty, value);
}
}
public static readonly DependencyProperty InfoTextProperty =
DependencyProperty.Register(
"InfoText",
typeof(string),
typeof(UserControl1),
new FrameworkPropertyMetadata(
new PropertyChangedCallback(ChangeText)));
private static void ChangeText(DependencyObject source, DependencyPropertyChangedEventArgs e)
{
(source as UserControl1).UpdateText(e.NewValue.ToString());
}
private void UpdateText(string NewText)
{
textBox1.Text = NewText;
}
public UserControl1()
{
InitializeComponent();
DataContext = this;
}
}
我得到我的用戶控件依賴屬性值,但我不能能我值綁定到文本box.am像這樣綁定Text =「{Binding Text}」是否正確,或者如何在用戶控件中綁定我的值
我附上我的示例項目, http://cid-08ec3041618e8ee4.skydrive.live.com/self.aspx/.SharedFavorites/dep2.rar
任何一眼能告訴什麼是錯在,
everythng運作良好,但我不能綁定在文本框中的值,
當u單擊該按鈕可以看出U傳遞的價值用戶控件在消息框中,但我不能在文本框中綁定該值。
爲什麼?
在您的問題中包含相關代碼會更好。 (幾乎)沒有人會下載你的整個項目,尋找相關的部分,然後嘗試找到問題。保持鏈接在那裏,但另外提供相關的代碼部分! – gehho
