【问题描述】:
我对 .NET/C#/WPF/XAML 比较陌生。我注意到有时控件似乎“缺少”影响样式的最简单属性。因此,必须使用类Style 来修改控件的外观。这没关系,但我发现自己在 Google/StackOverflow 上寻找要修改的特定属性的名称。
我正在为 ALL .NET Framework WPF 控件寻找规范且完整的默认控件样式和模板来源。
在你回答得太快之前,请继续阅读以了解我的困惑。
在此 Microsoft 文档页面 DataGrid Styles and Templates 上,我看到了 DataGridCell 的模板:
<!--Style and template for the DataGridCell.-->
<Style TargetType="{x:Type DataGridCell}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type DataGridCell}">
<Border x:Name="border"
BorderBrush="Transparent"
BorderThickness="1"
Background="Transparent"
SnapsToDevicePixels="True">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="FocusStates">
<VisualState x:Name="Unfocused" />
<VisualState x:Name="Focused" />
</VisualStateGroup>
<VisualStateGroup x:Name="CurrentStates">
<VisualState x:Name="Regular" />
<VisualState x:Name="Current">
<Storyboard>
<ColorAnimationUsingKeyFrames Storyboard.TargetName="border"
Storyboard.TargetProperty="(Border.BorderBrush).
(SolidColorBrush.Color)">
<EasingColorKeyFrame KeyTime="0"
Value="{StaticResource DatagridCurrentCellBorderColor}" />
</ColorAnimationUsingKeyFrames
>
</Storyboard>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<ContentPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
This page from MSDN forums,显示如下Style/Triggers/Setters。
<SolidColorBrush x:Key="{x:Static DataGrid.FocusBorderBrushKey}" Color="#FF000000"/>
<Style TargetType="{x:Type DataGridCell}">
<Setter Property="Background" Value="Transparent"/>
<Setter Property="BorderBrush" Value="Transparent"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type DataGridCell}">
<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="True">
<ContentPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.HighlightTextBrushKey}}"/>
<Setter Property="BorderBrush" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
</Trigger>
<Trigger Property="IsKeyboardFocusWithin" Value="True">
<Setter Property="BorderBrush" Value="{DynamicResource {x:Static DataGrid.FocusBorderBrushKey}}"/>
</Trigger>
</Style.Triggers>
</Style>
为什么我在第一个模板中看不到属性Background、Foreground、BorderBrush?
我感觉VisualState 的东西是一个参考,但我找不到来源。
