silverlight – 设置边框背景与模板绑定

概述Value =“{TemplateBinding HeaderColor}”我创建了自己的控件,我想知道是否可以将Border.Background绑定到模板属性.目前我正在使用如下的StaticResource设置它： <Color x:Key="ControlMouseOverColor">green</Color><ColorAnimationUsingKeyFrames Storybo Value =“{TemplateBinding headercolor}”我创建了自己的控件,我想知道是否可以将border.Background绑定到模板属性.目前我正在使用如下的StaticResource设置它：

<color x:Key="ControlMouSEOvercolor">green</color><colorAnimationUsingKeyFrames Storyboard.TargetProperty="(border.Background).(GradIEntBrush.GradIEntStops)[1].(GradIEntStop.color)" Storyboard.Targetname="headerLayout">    <EasingcolorKeyFrame KeyTime="0:0:6" Value="{StaticResource ControlMouSEOvercolor}" /></colorAnimationUsingKeyFrames>

我希望它是我控制的属性,并能够将其设置为模板绑定

<colorAnimationUsingKeyFrames Storyboard.TargetProperty="(border.Background).(GradIEntBrush.GradIEntStops)[1].(GradIEntStop.color)" Storyboard.Targetname="headerLayout">    <EasingcolorKeyFrame KeyTime="0:0:6" Value="{TemplateBinding headercolor}" /></colorAnimationUsingKeyFrames>

MainPage.xaml中

<ctrl:Selection GrID.Column="0" headercolor="Red" headerText="header Text" />

我的课：

public static Readonly DependencyProperty headercolorProperty =        DependencyProperty.Register("headercolor",typeof(System.windows.Media.color),typeof(Selection),new PropertyMetadata(System.windows.Media.colors.Red));public  System.windows.Media.color headercolor {    get { return (System.windows.Media.color)GetValue(headercolorProperty); }    set { SetValue(headercolorProperty,value); }}

如果我能够这样做,第二个选项不起作用？我没有收到错误,它只是没有改变我设置的颜色.

AngelWPF留下的评论要求更多代码,粘贴在下面,我正处于学习创建控件的开始阶段,想要注意,因为有很多我还没有,一次一件:)

Selection.cs

using System.windows;using System.windows.Controls;using System.windows.input;namespace SelectionControl.library {    [TemplateVisualState(name = Selection.MouseEnterStatename,Groupname = Selection.CommonStatesGroupname)]    [TemplateVisualState(name = Selection.MouseLeaveStatename,Groupname = Selection.CommonStatesGroupname)]    [TemplateVisualState(name = Selection.MouseleftUpStatename,Groupname = Selection.CommonStatesGroupname)]public class Selection : ContentControl {    public const string CommonStatesGroupname = "CommonStates";    public const string MouseEnterStatename = "MouseEnter";    public const string MouseLeaveStatename = "MouseLeave";    public const string MouseleftUpStatename = "MouseleftUp";    public Selection() {        this.DefaultStyleKey = typeof(Selection);        this.MouseEnter += new MouseEventHandler(OnMouseEnter);        this.MouseLeave += new MouseEventHandler(OnMouseLeave);        this.MouseleftbuttonUp += new MousebuttonEventHandler(OnMouseleftbuttonUp);    }    voID OnMouseleftbuttonUp(object sender,MousebuttonEventArgs e) {        this.GoToState(Selection.MouseleftUpStatename,true);    }    voID OnMouseLeave(object sender,MouseEventArgs e) {        this.GoToState(Selection.MouseLeaveStatename,true);    }    voID OnMouseEnter(object sender,MouseEventArgs e) {        this.GoToState(Selection.MouseEnterStatename,true);    }    private voID GoToState(string statename,bool useTransitions) {        visualstatemanager.GoToState(this,statename,useTransitions);    }    public static Readonly DependencyProperty headerTextProperty =        DependencyProperty.Register("headerText",typeof(string),new PropertyMetadata(""));    public string headerText {        get { return (string)GetValue(headerTextProperty); }        set { SetValue(headerTextProperty,value); }    }    public static Readonly DependencyProperty headercolorProperty =        DependencyProperty.Register("headercolor",new PropertyMetadata(System.windows.Media.colors.Red));    public  System.windows.Media.color headercolor {        get { return (System.windows.Media.color)GetValue(headercolorProperty); }        set { SetValue(headercolorProperty,value); }    }}}

解决方法 我在自定义依赖项属性上使用TemplateBinding得到了混合结果.因此,我使用了relativeSource TemplatedParent,它似乎适用于所有情况.

<EasingcolorKeyFrame KeyTime="0:0:.5" Value="{Binding headercolor,relativeSource={relativeSource TemplatedParent}}" />
