我已經做了BaseStyle,它看起來像這樣:如何在WPF中爲文本框和組合框應用相同的樣式?
<Style x:Key="BaseStyle" TargetType="{x:Type Control}">
<Setter Property="KeyboardNavigation.TabNavigation" Value="None" />
<Setter Property="AllowDrop" Value="true" />
<Setter Property="Background" Value="Transparent"></Setter>
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
<Setter Property="VerticalContentAlignment" Value="Stretch" />
<Setter Property="FontFamily" Value="Segoe UI" />
<Setter Property="FontSize" Value="12" />
<Setter Property="Padding" Value="8,5,3,3" />
<Setter Property="BorderThickness" Value="0" />
<Setter Property="SnapsToDevicePixels" Value="True" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Control}">
<Grid>
<Border x:Name="BorderBase" Background="White" BorderThickness="1,1,1.4,1.4" BorderBrush="Silver" CornerRadius="4" />
<Label x:Name="TextPrompt" Content="{TemplateBinding Tag}" Visibility="Collapsed" Focusable="False" Foreground="Silver"></Label>
<ScrollViewer Margin="0" x:Name="PART_ContentHost" Foreground="{DynamicResource OutsideFontColor}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsFocused" Value="True">
<Setter Property="BorderThickness" TargetName="BorderBase" Value="1,1,2.4,2.4"></Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
<Setter Property="Validation.ErrorTemplate">
<Setter.Value>
<ControlTemplate x:Name="InspectorErrorTemplate">
<StackPanel Orientation="Vertical">
<Border BorderBrush="Red" BorderThickness="1" CornerRadius="4">
<AdornedElementPlaceholder Name="adornerPlaceholder"/>
</Border>
</StackPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
而且用它來把它應用到一個文本框,其正常工作是這樣的:
<Style TargetType="{x:Type TextBox}" BasedOn="{StaticResource BaseStyle}" />
現在,我想我可以簡單地在組合框的文本框中使用相同的樣式。所以我想我必須在這部分補充一下:
<ControlTemplate x:Key="ComboBoxTextBox" TargetType="{x:Type TextBox}">
<Border x:Name="PART_ContentHost" Focusable="False" Background="{TemplateBinding Background}" />
<ControlTemplate.Triggers>
</ControlTemplate.Triggers>
</ControlTemplate>
但是,我不能添加像支持算法FMP =「{StaticResource的BaseStyle}」在ControlTemplate中做出如文本框在接收到焦點時獲取不同的邊框(請參閱BaseStyle中的IsFocused觸發器),或者在驗證被觸發的情況下顯示紅色彎曲的拐角......我做錯了什麼?
