知道我在哪里出错了这段代码。I want the TextBox to be Enabled when the associated RadioButton for it is selected, and then when a different radio button is selected I want it to be Enabled=False. 我创建了一个 ProxyMode 依赖属性,并根据是否选择了 Proxy 更改了 getter 以获取它的 bool 值。似乎不起作用......有什么想法吗?
// Proxy Host Name
public string Proxy
{
get { return (string)GetValue(ProxyProperty); }
set { SetValue(ProxyProperty, value); }
}
public static readonly DependencyProperty ProxyProperty =
DependencyProperty.Register("Proxy", typeof(string), typeof(ConfigWindowViewModel), new UIPropertyMetadata("[e.g. proxy.mycompany.com]"));
public bool ProxyMode
{
get { return Proxy == "Proxy"; }
set { SetValue(ProxyModeProperty, value); }
}
public static readonly DependencyProperty ProxyModeProperty =
DependencyProperty.Register("ProxyMode", typeof(bool), typeof(ConfigWindowViewModel));
和 XAML
<StackPanel Grid.Column="0" Margin="2">
<StackPanel Orientation="Horizontal" VerticalAlignment="Center">
<RadioButton IsChecked="{Binding Path=Mode, Converter={StaticResource enumBooleanConverter}, ConverterParameter=Proxy}"
VerticalAlignment="Center"
Padding="2,0,10,0">Proxy
</RadioButton>
<TextBox Text="{Binding Path=Proxy}"
IsEnabled="{Binding Path=ProxyMode}"
Width="Auto"
Name="ProxyHostTextBox"
VerticalAlignment="Center"
MinWidth="150"
/>
</StackPanel>
<RadioButton IsChecked="{Binding Path=Mode, Converter={StaticResource enumBooleanConverter}, ConverterParameter=Direct}">Direct</RadioButton>
</StackPanel>
