我想要完成的是自定义DataGrid
控件,以便每行都有圆角,没有网格线(只是我正在使用的设计)。
我一直在尝试创建一个ControlTemplate
来修改DataGridRow
控件,使它们具有预期的外观。到目前为止,这是我正在使用的:
<DataGrid Grid.Row="0" Grid.Column="0" Margin="5,5,5,5" AutoGenerateColumns="False" ItemsSource="{Binding Path=MyData}">
<DataGrid.Resources>
<Style x:Key="rowStyle" TargetType="{x:Type DataGridRow}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type DataGridRow}">
<Border CornerRadius="8,8,8,8" BorderBrush="Red" BorderThickness="2">
<ContentPresenter />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</DataGrid.Resources>
<DataGrid.Columns>
<DataGridTextColumn Header="Foo" />
<DataGridTextColumn Header="Baz" />
<DataGridTextColumn Header="Bar" />
</DataGrid.Columns>
</DataGrid>
这个版本显然很简陋(只是库存模板的边框),但是当我运行应用程序时,我看不出任何差异。
那么问题是如何自定义DataGridRow的控件模板?或者,如果这是不可行的,有没有更好的方法来实现我的目标:?

该行的实际模板比这复杂一点。看看下面的风格 - 它几乎是基本的风格,但我为IsMouseOver
和IsSelected
添加了一些设计和左触发器(随意删除它们)。
<Style TargetType="{x:Type DataGridRow}">
<Setter Property="Background"
Value="Transparent" />
<Setter Property="BorderBrush"
Value="Red" />
<Setter Property="BorderThickness"
Value="2" />
<Setter Property="SnapsToDevicePixels"
Value="true" />
<Setter Property="Validation.ErrorTemplate"
Value="{x:Null}" />
<Setter Property="ValidationErrorTemplate">
<Setter.Value>
<ControlTemplate>
<TextBlock Foreground="Red"
Margin="2,0,0,0"
Text="!"
VerticalAlignment="Center" />
</ControlTemplate>
</Setter.Value>
</Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type DataGridRow}">
<Border x:Name="DGR_Border"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}"
Background="{TemplateBinding Background}"
SnapsToDevicePixels="True"
CornerRadius="8,8,8,8">
<SelectiveScrollingGrid>
<SelectiveScrollingGrid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</SelectiveScrollingGrid.ColumnDefinitions>
<SelectiveScrollingGrid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
</SelectiveScrollingGrid.RowDefinitions>
<DataGridCellsPresenter Grid.Column="1"
ItemsPanel="{TemplateBinding ItemsPanel}"
SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" />
<DataGridDetailsPresenter Grid.Column="1"
Grid.Row="1"
SelectiveScrollingGrid.SelectiveScrollingOrientation="{Binding AreRowDetailsFrozen, ConverterParameter={x:Static SelectiveScrollingOrientation.Vertical}, Converter={x:Static DataGrid.RowDetailsScrollingConverter}, RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}}"
Visibility="{TemplateBinding DetailsVisibility}" />
<DataGridRowHeader Grid.RowSpan="2"
SelectiveScrollingGrid.SelectiveScrollingOrientation="Vertical"
Visibility="{Binding HeadersVisibility, ConverterParameter={x:Static DataGridHeadersVisibility.Row}, Converter={x:Static DataGrid.HeadersVisibilityConverter}, RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}}" />
</SelectiveScrollingGrid>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver"
Value="True">
<Setter TargetName="DGR_Border"
Property="Background"
Value="LightGray" />
</Trigger>
<Trigger Property="IsSelected"
Value="True">
<Setter TargetName="DGR_Border"
Property="Background"
Value="Gray" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
哦,顺便说一下,你有一个风格的键,但你不会在任何时候引用它 - 所以该行使用它的默认样式。要使用您的样式或上面提供的样式,请不要给出资源的密钥。

<Style TargetType="{x:Type DataGridColumnHeader}" x:Key="DatagridColumnHeaderStyle">
<Setter Property="VerticalContentAlignment" Value="Center" />
<Setter Property="Height" Value="35" />
<Setter Property="SeparatorBrush" Value="DarkRed" />
<Setter Property="FontWeight" Value="Black" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type DataGridColumnHeader}">
<Grid>
<Border x:Name="columnHeaderBorder"
BorderThickness="1"
Padding="3,0,3,0">
<ContentPresenter HorizontalAlignment="TemplateBinding HorizontalContentAlignment}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" />
</Border>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
在xaml中你可以输入以下代码
<DataGrid x:Name="myGridView"
Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="2"
Height="200" Margin="5,15,5,0"
AutoGenerateColumns="False"
ItemsSource="{Binding Person}"
SelectedItem="{Binding Path=PersonDetails, Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}" >
<DataGrid.Columns>
<DataGridTextColumn HeaderStyle="{StaticResource DatagridColumnHeaderStyle}" Width="200" Header="Customer Name" Binding="{Binding Path=Name}"/>
<DataGridTextColumn HeaderStyle="{StaticResource DatagridColumnHeaderStyle}" Width="250" Header="Customer Address" Binding="{Binding Path=Address}"/>
<DataGridTextColumn HeaderStyle="{StaticResource DatagridColumnHeaderStyle}" Width="100" Header="Order Id" Binding="{Binding Path=OrderId}"/>
</DataGrid.Columns>
