【转】WPF自定义控件与样式(7)-列表控件DataGrid与ListView自定义样式
一．前言
申明：WPF自定义控件与样式是一个系列文章，前后是有些关联的，但大多是按照由简到繁的顺序逐步发布的等。
本文主要内容：
- DataGrid自定义样式；
- ListView自定义样式；
二．DataGrid自定义样式
DataGrid是常用的数据列表显示控件，先看看实现的效果（动态图，有点大）：
DataGrid控件样式结构包括以下几个部分：
-
- 列头header样式
- 调整列头宽度的列分割线样式
- 行样式
- 行头调整高度样式
- 行头部样式
- 单元格样式
在本文的样式定义中，默认开启了DataGrid的虚拟化，以支持大数据，若实际使用数据确定很小，应该关闭虚拟化，因为虚拟化本身也是有成本的。样式代码：
<!--调整列头宽度样式--> <Style x:Key="DefaultColumnHeaderGripperStyle" TargetType="{x:Type Thumb}"> <Setter Property="Width" Value="8" /> <Setter Property="Background" Value="{StaticResource

</ControlTemplate> </Setter.Value> </Setter> </Style> </Setter.Value> </Setter> <!--DataGrid控件模板--> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type DataGrid}"> <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" x:Name="border" Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}" SnapsToDevicePixels="True"> <ScrollViewer x:Name="DG_ScrollViewer" Focusable="false"> <ScrollViewer.Template> <ControlTemplate TargetType="{x:Type ScrollViewer}"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition x:Name="col_rowheader" Width="1" /> <ColumnDefinition Width="*" /> <ColumnDefinition Width="Auto" /> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition Height="Auto" /> <RowDefinition Height="*" /> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <!--表格头部--> <DataGridColumnHeadersPresenter x:Name="PART_ColumnHeadersPresenter" Grid.Column="1" Grid.ColumnSpan="2" Visibility="{Binding HeadersVisibility, ConverterParameter={x:Static DataGridHeadersVisibility.Column}, Converter={x:Static DataGrid.HeadersVisibilityConverter}, RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}}" /> <!--主数据区--> <Grid Grid.Row="1" Grid.ColumnSpan="2"> <ScrollContentPresenter x:Name="PART_ScrollContentPresenter" CanContentScroll="{TemplateBinding CanContentScroll}" Grid.ColumnSpan="2" /> </Grid> <!--垂直滑动条--> <ScrollBar x:Name="PART_VerticalScrollBar" Grid.Column="2" Maximum="{TemplateBinding ScrollableHeight}" Orientation="Vertical" Grid.Row="0" Grid.RowSpan="3" Visibility="{TemplateBinding ComputedVerticalScrollBarVisibility}" Value="{Binding VerticalOffset, Mode=OneWay, RelativeSource={RelativeSource TemplatedParent}}" ViewportSize="{TemplateBinding ViewportHeight}" /> <!--横向滑动条--> <ScrollBar x:Name="PART_HorizontalScrollBar" Grid.Column="0" Grid.ColumnSpan="2" Grid.Row="2" Maximum="{TemplateBinding ScrollableWidth}" Orientation="Horizontal" Visibility="{TemplateBinding ComputedHorizontalScrollBarVisibility}" Value="{Binding HorizontalOffset, Mode=OneWay, RelativeSource={RelativeSource TemplatedParent}}" ViewportSize="{TemplateBinding ViewportWidth}" /> </Grid> </ControlTemplate> </ScrollViewer.Template> <ItemsPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" /> </ScrollViewer> </Border> <ControlTemplate.Triggers> <Trigger Property="IsEnabled" Value="false"> <Setter Property="Opacity" Value="{StaticResource DisableOpacity}" TargetName="border" /> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> <Style.Triggers> <Trigger Property="IsGrouping" Value="true"> <Setter Property="ScrollViewer.CanContentScroll" Value="false" /> </Trigger> </Style.Triggers> </Style>
最后一个就是DataGrid的样式了，主要是重写定义了滑动条的布局，使得整体效果更加协调，属性AlternationCount可用来设置行交替色，而具体实现交替色是在上面行（DataGridRow）样式中通过触发器实现的。
使用和原本一样，示例代码：
<DataGrid Grid.Row="1" x:Name="gridList" Margin="3" GridLinesVisibility="None" BorderThickness="0"> <DataGrid.Columns> <DataGridTextColumn Width="120" Header="好好学习" Binding="{Binding Name}"></DataGridTextColumn> <DataGridTextColumn Header="Manufacturer" Binding="{Binding Manufacturer}"></DataGridTextColumn> <DataGridTemplateColumn Header="Mode"> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <CheckBox core:ControlAttachProperty.FIconSize="18">选中我啊</CheckBox> </DataTemplate> </DataGridTemplateColumn.CellTemplate> </DataGridTemplateColumn> <DataGridTextColumn Header="Name" Binding="{Binding Name}" Width="300"></DataGridTextColumn> </DataGrid.Columns> </DataGrid>
三．ListView自定义样式
ListView作为列表控件，可以支持非常灵活的呈现效果，本文实现两种基本的样式效果，在后面的文章会有其他需求扩展的分享，效果图（动态图，有点大）：
如上面的效果图，ListView实现了两种基本样式：
-
- 类似ListBox的基础列表样式；
- 支持多列（效果类型DataGrid）的样式；
ListView也是默认支持虚拟化的，也重新定义了滑动条的布局样式，所有样式定义代码：
<!--DefaultGridViewScrollViewerStyle--> <Style x:Key="DefaultGridViewScrollViewerStyle" TargetType="{x:Type ScrollViewer}" BasedOn="{StaticResource {x:Static GridView.GridViewScrollViewerStyleKey}}"> <Setter Property="Focusable" Value="false" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type ScrollViewer}"> <Grid Background="{TemplateBinding Background}" SnapsToDevicePixels="true"> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> <ColumnDefinition Width="Auto" /> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition Height="*" /> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <DockPanel Margin="{TemplateBinding Padding}"> <ScrollViewer DockPanel.Dock="Top" Focusable="false" HorizontalScrollBarVisibility="Hidden" VerticalScrollBarVisibility="Hidden"> <GridViewHeaderRowPresenter AllowsColumnReorder="{Binding TemplatedParent.View.AllowsColumnReorder, RelativeSource={RelativeSource TemplatedParent}}"
