在我當前的項目中,我有這個XAML文件,我定義了必須應用於不同類型的自定義小部件的視覺樣式。在XAML中定義矩形的控件模板
例如,風格爲「DirectLineButton」(自定義,從WPF的按鈕將繼承類)如下:
<Style x:Key="DirectLineButtonTemplate" TargetType="{x:Type View:DirectLineButton}">
<Setter Property="SnapsToDevicePixels" Value="true"/>
<Setter Property="OverridesDefaultStyle" Value="true"/>
<Setter Property="MinHeight" Value="23"/>
<Setter Property="MinWidth" Value="75"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border x:Name="MyBorder"
CornerRadius="2"
BorderThickness="2"
Background="Gold"
BorderBrush="Gray">
<ContentPresenter Margin="2"
HorizontalAlignment="Center"
VerticalAlignment="Center"
RecognizesAccessKey="True"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="View:DirectLineButton.State" Value="DirectLineAvailable">
<Setter TargetName="MyBorder" Property="Background" Value="Gold"/>
</Trigger>
<Trigger Property="View:DirectLineButton.State" Value="DirectLineIdle">
<Setter TargetName="MyBorder" Property="Background" Value="Silver"/>
</Trigger>
<Trigger Property="View:DirectLineButton.State" Value="DirectLineBusy">
<Setter TargetName="MyBorder" Property="Background" Value="Green"/>
</Trigger>
<Trigger Property="View:DirectLineButton.State" Value="DirectLineCalled">
<Setter TargetName="MyBorder" Property="Background" Value="LightBlue"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
現在,我需要通過定義一個矩形樣式複製這個想法。不幸的是,當我嘗試爲一個矩形定義一個ControlTemplate時,WPF會標記一條錯誤消息,你能提出一個解決方法嗎?看下面的代碼我試圖嘗試:
<Style x:Key="MyRectangleTemplate" TargetType="{x:Type Rectangle}">
<Setter Property="SnapsToDevicePixels" Value="true"/>
<Setter Property="OverridesDefaultStyle" Value="true"/>
<Setter Property="MinHeight" Value="23"/>
<Setter Property="MinWidth" Value="75"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Rectangle}">
<Border x:Name="MyBorder"
CornerRadius="2"
BorderThickness="2"
Background="Gold"
BorderBrush="Gray">
<ContentPresenter Margin="2"
HorizontalAlignment="Center"
VerticalAlignment="Center"
RecognizesAccessKey="True"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="View:DirectLineButton.State" Value="DirectLineAvailable">
<Setter TargetName="MyBorder" Property="Background" Value="Gold"/>
</Trigger>
<Trigger Property="View:DirectLineButton.State" Value="DirectLineIdle">
<Setter TargetName="MyBorder" Property="Background" Value="Silver"/>
</Trigger>
<Trigger Property="View:DirectLineButton.State" Value="DirectLineBusy">
<Setter TargetName="MyBorder" Property="Background" Value="Green"/>
</Trigger>
<Trigger Property="View:DirectLineButton.State" Value="DirectLineCalled">
<Setter TargetName="MyBorder" Property="Background" Value="LightBlue"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
在此先感謝!
實際上,'Rectangle'從'FrameworkElement'衍生設置適當

。控制模板僅適用於...控件:) –是的,我的不好,我有點困惑,它只是VisualStudio的錯誤,它提供給我們這麼多的信息,我們不必記住每一件事。 – ethicallogics
