wpf datagrid定制（边界，单元角等） [英] wpf datagrid customization (border, cell corners, etc.)

问题描述

我正在尝试在xaml中设置wpf数据网格的样式，以使其看起来像此图像。那可能吗？
我尝试了很多事情，但仍然存在以下问题：

i'm trying to style a wpf datagrid in xaml to make it look like this image. Is that possible? I tried numerous things, but i still have the following problems:

1. 单元格边框属性仅影响选定的单元格。否则，我只有1px的细线，可以通过VerticalGridLinesBrush着色


2. 如果我在datagrid.cell级别上指定了背景色，它将覆盖所选内容


3. 我不知道是否甚至可以在单元格级别上圆角化（也用于选择）

我非常感谢您提供的四个帮助。如果有帮助，我明天可以在这里进行几次尝试。

I'm grateful four any help. If it helps i can post a couple of tries here tomorrow.

编辑：
这是我生成datagrid的代码，您可以看到我尝试了背景和datagrid.cellstyle中的边距值，但是会导致上述问题：

This is my code generating the datagrid, as you can see I experimented with background and margin values in datagrid.cellstyle, however it resulted in the above problems:

<DataGrid x:Name="Grid" Height="305" VerticalAlignment="Top" Width="505" BorderThickness="1" 
      AutoGenerateColumns="False" SelectionUnit="Cell" HeadersVisibility="None" ItemsSource="{Binding}" 
      CanUserSortColumns="False" CanUserResizeColumns="False" CanUserReorderColumns="False" CanUserResizeRows="False" 
      IsReadOnly="True" HorizontalAlignment="Left" BorderBrush="White" HorizontalScrollBarVisibility="Disabled" VerticalScrollBarVisibility="Disabled" 
      ScrollViewer.CanContentScroll="False" MouseLeftButtonUp="ScreenGrid_MouseLeftButtonUp" Margin="10,10,0,0" Background="#FF000000"
      VerticalGridLinesBrush="White" HorizontalGridLinesBrush="White" SelectedCellsChanged="ScreenGrid_SelectedCellsChanged" >
    <DataGrid.Resources>
        <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Blue"></SolidColorBrush>
        <Style x:Key="DataGridRowStyleColoured" TargetType="{x:Type DataGridRow}">
            <Setter Property="Background" Value="#FF000000" />
        </Style>
    </DataGrid.Resources>
    <DataGrid.RowStyle>
        <StaticResource ResourceKey="DataGridRowStyleColoured"/>
    </DataGrid.RowStyle>
    <DataGrid.CellStyle>
        <Style TargetType="DataGridCell">
            <Setter Property="BorderThickness" Value="0"/>
            <!--<Setter Property="Margin" Value="5,5,5,5"/> -->
            <!-- <Setter Property="Background" Value="White"/> -->
        </Style>
    </DataGrid.CellStyle>
</DataGrid>

推荐答案

这应该使您入门：-

<Page
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
  <Page.Resources>
      <Style x:Key="cellStyle" TargetType="DataGridCell">
        <Setter Property="Padding" Value="0" />
        <Setter Property="Margin" Value="2" />
        <Setter Property="Background" Value="Black" />
        <Setter Property="Template">
          <Setter.Value>
                <ControlTemplate TargetType="DataGridCell">
                    <Border Background="Black" BorderThickness="0">
                      <Border x:Name="border"
                              BorderBrush="White"
                              BorderThickness="2"
                              Background="Black"
                              CornerRadius="5">
                          <ContentPresenter />
                      </Border>
                    </Border>
                    <ControlTemplate.Triggers>
                      <DataTrigger Binding="{Binding RelativeSource={RelativeSource Self}, Path=IsSelected}" Value="true">
                        <Setter TargetName="border" Property="Background" Value="Orange"/>
                      </DataTrigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
          </Setter.Value>
        </Setter>
      </Style>

      <Style x:Key="rowStyle" TargetType="DataGridRow">
        <Setter Property="Padding" Value="0" />
        <Setter Property="Margin" Value="0" />
        <Setter Property="BorderThickness" Value="0"/>
        <Setter Property="Background" Value="Black" />
      </Style>

  <Grid>  
    <DataGrid HeadersVisibility="None" GridLinesVisibility="None" SelectionMode="Single" SelectionUnit="Cell" IsReadOnly="true"
      RowStyle="{StaticResource rowStyle}" CellStyle="{StaticResource cellStyle}" 
      Background="Black" Foreground="White" ItemsSource="{Binding MyData}" />
  </Grid>
</Page>

大部分操作是通过重新模板化 DataGridCell 。内边框创建圆角，而外边框确保圆角周围的空间中有黑色背景。

Most of it is done by re-templating the DataGridCell. The inner border creates the rounded corners, while the outer border ensures there is a black background in the "space" around the rounded corners.

我还添加了一个触发器设置所选单元格的背景色。 DataGrid配置为用于单单元格选择-看起来您的将是 Multiple。

I've also added a trigger that sets the selected cell's background colour. The DataGrid is configured for single-cell selection - it looks like yours will be "Multiple".
