工作,我已经创建的样本用户控制动态与用户绑定,静态就是在Silverlight和MVVM
RestrictedBox.xaml
<UserControl.Resources>
<Converters:EnumToVisibilityConverter x:Key="enumToVisConverter" />
<Converters:EnumToVisibilityConverterReverse x:Key="enumToVisConverterReverse" />
</UserControl.Resources>
<Grid x:Name="LayoutRoot" Background="White" Width="Auto">
<StackPanel Margin="0">
<TextBox Text="{Binding Value}" Visibility="{Binding Type,Converter={StaticResource enumToVisConverter}}" BorderBrush="Green" />
<PasswordBox Password="{Binding Value}" Visibility="{Binding Type,Converter={StaticResource enumToVisConverterReverse}}" BorderBrush="Red" />
</StackPanel>
</Grid>
RestrictedBox.xaml.cs器不起作用
public partial class RestrictedBox : UserControl
{
public RestrictedBox()
{
InitializeComponent();
//If i bind static value and uncomment following line then it is working.
//If i bind static value and comment following line then it is not working
this.DataContext = this;
//Dynamic binding does not work using this code.
}
public string Value
{
get { return (string)GetValue(ValueProperty); }
set { SetValue(ValueProperty, value); }
}
public static readonly DependencyProperty ValueProperty = DependencyProperty.Register("Value", typeof(string), typeof(RestrictedBox), new PropertyMetadata("", ValueChanged));
private static void ValueChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
}
public Mode Type
{
get { return (Mode)GetValue(TypeProperty); }
set { SetValue(TypeProperty, value); }
}
public static readonly DependencyProperty TypeProperty = DependencyProperty.Register("Type", typeof(Mode), typeof(RestrictedBox), new PropertyMetadata(TypeChanged));
private static void TypeChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
}
}
LoginViewModel.cs
public class LoginViewModel : INotifyPropertyChanged, IRegionMemberLifetime
{
private string _UserName = "Imdadhusen Sunasara";
public string UserName
{
get { return _UserName; }
set
{
_UserName = value;
OnPropertyChanged("UserName");
}
}
}
LoginView.xaml(这下面的行不绑定工作)
<control:RestrictedBox Value="{Binding UserName}" Type="Text" />
这是工作(与静态结合)
<control:RestrictedBox Value="Imdadhusen" Type="Text" />
Th anks, Imdadhusen
首先,我看到你有很多的问题,了解什么绑定。例如,没有像“静态绑定”这样的东西。绑定只能是“动态”的。我几乎不可能推荐Mattew McDonald的书“C#中的Pro Silverlight 4” - 只读一次,您将节省大量时间。 – chopikadze 2012-02-27 14:04:45
