具有VisualStates的WPF ControlTemplate
|
我想用预定义的VisualStates创建一个ControlTemplate。我想将它们与GoToStateActions和DataTriggers一起使用。
我不知道这里到底出了什么问题。在我看来，绑定不是按照我认为的那样建立的。
namespace ControlTemplateVisualState
{
using System.Windows.Controls;
public class MyControl : ContentControl
{
public MyControl()
{
this.DefaultStyleKey = typeof(MyControl);
}
}
}

<ControlTemplate x:Key=\"MyControlTemplate\" TargetType=\"{x:Type ControlTemplateVisualState:MyControl}\">
<Grid x:Name=\"grid\" Background=\"Red\">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name=\"VisualStateGroup\">
<VisualState x:Name=\"IsDisabledState\">
<Storyboard>
<ColorAnimationUsingKeyFrames Storyboard.TargetProperty=\"(Panel.Background).(SolidColorBrush.Color)\" Storyboard.TargetName=\"grid\">
<EasingColorKeyFrame KeyTime=\"0\" Value=\"#FF2BFF00\"/>
</ColorAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<i:Interaction.Triggers>
<ei:DataTrigger Binding=\"{Binding IsEnabled, ElementName=grid}\" Value=\"False\">
<ei:GoToStateAction StateName=\"IsDisabledState\"/>
</ei:DataTrigger>
</i:Interaction.Triggers>
</Grid>
</ControlTemplate>
<Style TargetType=\"{x:Type ControlTemplateVisualState:MyControl}\">
<Setter Property=\"Background\" Value=\"#FF0010FF\"/>
<Setter Property=\"Template\" Value=\"{StaticResource MyControlTemplate}\"/>
</Style>
</ResourceDictionary>
<Window

public static void GoToState(Control control, bool useTransitions, params string[] stateNames) { foreach (var name in stateNames) { if (VisualStateManager.GoToState(control, name, useTransitions)) break; } }
