我想覆蓋元素觸發器,因此,單擊文本框時,它會更改父邊框的屬性。WPF觸發器更改父項屬性
但是父目標名不被識別。下面是代碼示例:
<Style x:Key="customstyle" TargetType="{x:Type local:customcontrol}">
<Setter Property="Background" Value="{StaticResource DownGradientBrush}"/>
<Setter Property="BorderBrush" Value="{StaticResource DownGradientBorder}"/>
<Setter Property="Foreground" Value="{StaticResource TextBoxForeground}"/>
<Setter Property="HorizontalAlignment" Value="Center"/>
<Setter Property="VerticalAlignment" Value="Center"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type local:customcontrol}">
<Border x:Name="Bd" BorderBrush="{TemplateBinding BorderBrush}">
<Grid>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="15"/>
</Grid.ColumnDefinitions>
<Border Grid.Column="0"
Grid.RowSpan="2"
HorizontalAlignment="Stretch">
<TextBox x:Name="TextBox"
Grid.Column="0"
Grid.RowSpan="2"
Text="{Binding RelativeSource={x:Static RelativeSource.TemplatedParent}, Path=Value}"
Width="Auto"
Height="Auto">
<TextBox.Style>
<Style BasedOn="{StaticResource StyleTextBox}" TargetType="{x:Type TextBox}">
<Style.Triggers>
<Trigger Property="IsFocused" Value="True">
<Setter TargetName="Bd"
Property="Background"
Value="{StaticResource CustomGradientBorder}" />
</Trigger>
<Trigger Property="IsFocused" Value="True" />
</Style.Triggers>
</Style>
</TextBox.Style>
</TextBox>
</Border>
</Grid>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsFocused" Value="True">
<Setter TargetName="Bd" Property="BorderBrush" Value="{StaticResource CustomGradientBorder}" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
謝謝,這樣做是正常的:) – immuner 2009-11-11 18:53:14
