C# 如何在XAML中绑定依赖项属性?
我有一个用户控件,其中我在其代码隐藏中定义了依赖项属性:C# 如何在XAML中绑定依赖项属性?,c#,wpf,xaml,custom-controls,C#,Wpf,Xaml,Custom Controls,我有一个用户控件,其中我在其代码隐藏中定义了依赖项属性: public static readonly DependencyProperty MyDependencyPropertyProperty = DependencyProperty.Register( "MyDependencyProperty", typeof(MyType), typeof(MyView), new PropertyMetadata(null)); public MyType MyDepe
public static readonly DependencyProperty MyDependencyPropertyProperty = DependencyProperty.Register(
"MyDependencyProperty", typeof(MyType), typeof(MyView), new PropertyMetadata(null));
public MyType MyDependencyProperty
{
get
{
return (MyType)GetValue(MyDependencyPropertyProperty);
}
set
{
SetValue(MyDependencyPropertyProperty, value);
}
}
现在我想将视图中的dependecy属性绑定到视图模型中的属性,如下所示:
<UserControl x:Class="Myproject.Views.MyViewView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:i="http://schemas.microsoft.com/xaml/behaviors"
mc:Ignorable="d"
d:DesignHeight="450" d:DesignWidth="1000"
**MyDependencyPropertyProperty {Binding MyPropetyInViewModel}**
Name="MyView">
这段代码给出了我想要的想法,即使用dependency属性来设置绑定。通常,您需要设置dependency属性,在这里使用
用户控件
<MyViewView MyDependencyPropertyProperty="{Binding MyPropetyInViewModel}" />
如果确实希望在控件本身中执行此操作,可以创建一个样式来设置值
<UserControl x:Class="Myproject.Views.MyViewView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:i="http://schemas.microsoft.com/xaml/behaviors"
xmlns:local="clr-namespace:Myproject.Views"
mc:Ignorable="d"
d:DesignHeight="450"
d:DesignWidth="1000"
Name="MyView">
<UserControl.Style>
<Style>
<Setter Property="local:MyViewView.MyDependencyPropertyProperty" Value="{Binding MyPropetyInViewModel}"/>
</Style>
</UserControl.Style>
<!-- ...other markup -->
</UserControl>
