Style a wpf datagrid
提问by tesla1060
I have found a sample style for wpf as per below, the main thing it does is to change the background color of DataGridColumnHeader and still preserve the sorting arrow. as can be seen the sorting arrow is explicitly specified in the style as UpArrow and DownArrow.
我找到了一个 wpf 的示例样式，如下所示，它的主要作用是更改 DataGridColumnHeader 的背景颜色并仍然保留排序箭头。可以看出，排序箭头在样式中明确指定为 UpArrow 和 DownArrow。
<Style x:Key="SuojiHeaderStyle" TargetType="{x:Type DataGridColumnHeader}">
<Setter Property="VerticalContentAlignment" Value="Center" />
<Setter Property="Background" Value="{StaticResource HeaderBrush}" />
<Setter Property="Padding" Value="5" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type DataGridColumnHeader}">
<Grid>
<dg:DataGridHeaderBorder SortDirection="{TemplateBinding SortDirection}"
IsHovered="{TemplateBinding IsMouseOver}"
IsPressed="{TemplateBinding IsPressed}"
IsClickable="{TemplateBinding CanUserSort}"
Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}"
Padding ="{TemplateBinding Padding}"
SeparatorVisibility="{TemplateBinding SeparatorVisibility}"
SeparatorBrush="{TemplateBinding SeparatorBrush}">
<ContentPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" />
</dg:DataGridHeaderBorder>
<Thumb x:Name="PART_LeftHeaderGripper"
HorizontalAlignment="Left"
Style="{StaticResource ColumnHeaderGripperStyle}"/>
<Thumb x:Name="PART_RightHeaderGripper"
HorizontalAlignment="Right"
Style="{StaticResource ColumnHeaderLeftGripperStyle}"/>
<Path Name="UpArrow" Fill="Black" HorizontalAlignment="Right" VerticalAlignment="Center" Margin="7,0,7,0" Visibility="Hidden">
<Path.Data>
<PathGeometry>
<PathFigure StartPoint="0,0">
<LineSegment Point="6,0"/>
<LineSegment Point="3,5"/>
<LineSegment Point="0,0"/>
</PathFigure>
</PathGeometry>
</Path.Data>
</Path>
<Path Name="DownArrow" Fill="Black" HorizontalAlignment="Right" VerticalAlignment="Center" Margin="7,0,7,0" Visibility="Hidden">
<Path.Data>
<PathGeometry>
<PathFigure StartPoint="0,5">
<LineSegment Point="6,5"/>
<LineSegment Point="3,0"/>
<LineSegment Point="0,5"/>
</PathFigure>
</PathGeometry>
</Path.Data>
</Path>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="SortDirection" Value="Descending">
<Setter TargetName="UpArrow" Property="Visibility" Value="Hidden"/>
<Setter TargetName="DownArrow" Property="Visibility" Value="Visible"/>
</Trigger>
<Trigger Property="SortDirection" Value="Ascending">
<Setter TargetName="DownArrow" Property="Visibility" Value="Hidden"/>
<Setter TargetName="UpArrow" Property="Visibility" Value="Visible"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
when I apply this style to my DataGrid
当我将此样式应用于我的 DataGrid 时
<DataGrid ItemsSource="{Binding Source={StaticResource cvs}}" x:Name="MasterAllGrid" AutoGenerateColumns="False"
HeadersVisibility="All" CanUserAddRows="False" HorizontalGridLinesBrush="#f0f0f0" VerticalGridLinesBrush="#f0f0f0" ColumnHeaderStyle ="{StaticResource SuojiHeaderStyle}"
VerticalAlignment="Stretch" SelectionChanged="MasterAllGrid_SelectionChanged" VerticalScrollBarVisibility="Auto" Background="{x:Null}">
<DataGrid.Columns>
<DataGridTextColumn Header="ticker" Binding="{Binding Path=Ticker}"/>
the arrow in the style overlapps with the Column Header Text (Sorry I am not allowed to posed pic by StackOverflow because I am new). How to make it not to overlap?
样式中的箭头与列标题文本重叠（对不起，我不允许通过 StackOverflow 摆姿势，因为我是新人）。如何让它不重叠？
