我在 Silverlight 4 页面上有四个数据网格。我正在尝试为每个网格设置不同的列标题样式。我发现这个 XAML 在我将它嵌入到<sdk:DataGrid.ColumnHeaderStyle>
标签内的每个 DataGrid 中时有效:
<Style TargetType="primitives:DataGridColumnHeader" >
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="primitives:DataGridColumnHeader">
<Grid Name="Root">
<vsm:VisualStateManager.VisualStateGroups>
<vsm:VisualStateGroup x:Name="SortStates" >
<vsm:VisualStateGroup.Transitions>
<vsm:VisualTransition GeneratedDuration="00:00:0.1" />
</vsm:VisualStateGroup.Transitions>
<vsm:VisualState x:Name="Unsorted" />
<vsm:VisualState x:Name="SortAscending">
<Storyboard>
<DoubleAnimation Storyboard.TargetName="SortIcon" Storyboard.TargetProperty="Opacity" Duration="0" To="1.0" />
</Storyboard>
</vsm:VisualState>
<vsm:VisualState x:Name="SortDescending">
<Storyboard>
<DoubleAnimation Storyboard.TargetName="SortIcon" Storyboard.TargetProperty="Opacity" Duration="0" To="1.0" />
<DoubleAnimation Storyboard.TargetName="SortIconTransform" Storyboard.TargetProperty="ScaleY" Duration="0" To="-.9" />
</Storyboard>
</vsm:VisualState>
</vsm:VisualStateGroup>
</vsm:VisualStateManager.VisualStateGroups>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<Rectangle x:Name="BackgroundRectangle" Stretch="Fill" Grid.ColumnSpan="2" Grid.RowSpan="2">
<Rectangle.Fill>
<LinearGradientBrush StartPoint="0,0" EndPoint="0,1">
<GradientStop Color="Transparent" Offset="0" />
<GradientStop Color="LavenderBlush" Offset="1" />
</LinearGradientBrush>
</Rectangle.Fill>
</Rectangle>
<ContentPresenter Grid.RowSpan="2" Content="{TemplateBinding Content}" Cursor="{TemplateBinding Cursor}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Margin="{TemplateBinding Padding}" />
<Rectangle Name="VerticalSeparator" Grid.RowSpan="2" Grid.Column="2" Width="1" VerticalAlignment="Stretch" Fill="{TemplateBinding SeparatorBrush}" Visibility="{TemplateBinding SeparatorVisibility}" />
<Path Grid.RowSpan="2" Name="SortIcon" RenderTransformOrigin=".5,.5" HorizontalAlignment="Left" VerticalAlignment="Center" Opacity="0" Grid.Column="1" Stretch="Uniform" Width="8" Data="F1 M -5.215,6.099L 5.215,6.099L 0,0L -5.215,6.099 Z ">
<Path.Fill>
<SolidColorBrush Color="#FF444444" />
</Path.Fill>
<Path.RenderTransform>
<TransformGroup>
<ScaleTransform x:Name="SortIconTransform" ScaleX=".9" ScaleY=".9" />
</TransformGroup>
</Path.RenderTransform>
</Path>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
当我将它放在单独的资源字典中并删除上述标签时,它也可以工作,适用于所有四个标题。但是当我尝试在资源字典中创建它的特定版本但将第一行更改为:
<Style x:Key="ADGridColumnHeader" TargetType="primitives:DataGridColumnHeader" >
并将其添加到 DataGrid:
ColumnHeaderStyle="PhoneMasterGridColumnHeader"
我收到错误:发生 XamlParseException:无法从文本“PhoneMasterGridColumnHeader”创建“System.Windows.Style”。我不知道出了什么问题。我仍在努力掌握样式和资源字典。任何的想法?
