WPF DataGrid中的虚拟水平网格线 | DataGrid中的虚拟水平网格线

本文介绍了WPF DataGrid中的虚拟水平网格线的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

有没有办法在WPF数据网格中的水平网格线上有一条虚线？我已经在世界各地搜索，似乎找不到具体的做法。一个可以解决这个问题的解决方案是设置Datagrid.RowStyle。我已经尝试过这个错误。我把datagrid绑定到一个datatable。 2列只是文本，第3列是图像列。对于这些列，我使用DataGridTemplateColumn。文本块和图像。我希望你可以帮助我...如果你想在这里我的代码示例是。

 < StackPanel> 
< dg：DataGrid Name =questionList

 AutoGenerateColumns =False
 Background =White
 Margin =42， 32,43,0

解决方案

您可以禁用绘制的水平网格线在 DataGrid 中指定 GridLinesVisibility =Vertical的代码。然后，您可以重新模板 DataGridRow ，并在每行末尾添加虚线

看起来像这样：

 < DataGrid GridLinesVisibility =Vertical> 
< DataGrid.RowStyle> 
< Style TargetType =DataGridRow> 
< Setter Property =Template> 
< Setter.Value> 
< ControlTemplate TargetType ={x：Type DataGridRow}> 
< Border x：Name =DGR_BorderBorderBrush ={TemplateBinding BorderBrush}BorderThickness ={TemplateBinding BorderThickness}Background ={TemplateBinding Background}SnapsToDevicePixels =True> 
< SelectiveScrollingGrid> 
< SelectiveScrollingGrid.ColumnDefinitions> 
< ColumnDefinition Width =Auto/> 
< ColumnDefinition Width =*/> 
< /SelectiveScrollingGrid.ColumnDefinitions> 
< SelectiveScrollingGrid.RowDefinitions> 
< RowDefinition Height =*/> 
< RowDefinition Height =Auto/> 
< RowDefinition Height =Auto/> 
< /SelectiveScrollingGrid.RowDefinitions> 
< DataGridCellsPresenter Grid.Column =1ItemsPanel ={TemplateBinding ItemsPanel}SnapsToDevicePixels ={TemplateBinding SnapsToDevicePixels}/> 
< DataGridDetailsPresenter Grid.Column =1Grid.Row =1SelectiveScrollingGrid.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 =2SelectiveScrollingGrid.SelectiveScrollingOrientation =VerticalVisibility ={Binding HeadersVisibility，ConverterParameter = {x：Static DataGridHeadersVisibility.Row}，Converter = {x：Static DataGrid.HeadersVisibilityConverter} RelativeSource = {RelativeSource AncestorType = {x：Type DataGrid}}}/> 
< Path Grid.Row =2Grid.ColumnSpan =2
 Data =M0,0.5 L1,0.5
 Stretch =FillStroke =BlackStrokeThickness =1
 StrokeDashArray =1.0 2.0/> 
< / SelectiveScrollingGrid>

< / ControlTemplate> 
< /Setter.Value> 
< / Setter> 
< / Style> 
< /DataGrid.RowStyle> 
<！ -  ...  - >

编辑：以下是3.5 DataGrid

 < Custom：DataGrid GridLinesVisibility =Vertical>

Is there a way to have a dotted line on the horizontal grid lines in WPF datagrid? I have googled everywhere and cannot seem to find a concrete way of doing so. One solution that may solve this is setting the Datagrid.RowStyle. I have tried this and it causes error. I have binded my datagrid to a datatable. 2 columns are just text and the 3rd one is an image column. For this columns, I used DataGridTemplateColumn. Textblock and Image. I hope you can help me guys...If you want a sample of my code here it is.

解决方案

You can disable the Horizontal Grid Lines which are drawn in code by specifying GridLinesVisibility="Vertical" in the DataGrid. You could then re-template DataGridRow and add the dashed line at the end of each row

Looks like this:

<DataGrid GridLinesVisibility="Vertical">
    <DataGrid.RowStyle>
        <Style TargetType="DataGridRow">
            <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">
                            <SelectiveScrollingGrid>
                                <SelectiveScrollingGrid.ColumnDefinitions>
                                    <ColumnDefinition Width="Auto"/>
                                    <ColumnDefinition Width="*"/>
                                </SelectiveScrollingGrid.ColumnDefinitions>
                                <SelectiveScrollingGrid.RowDefinitions>
                                    <RowDefinition Height="*"/>
                                    <RowDefinition Height="Auto"/>
                                    <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}}}"/>
                                <Path Grid.Row="2" Grid.ColumnSpan="2"
                                      Data="M0,0.5 L1,0.5"
                                      Stretch="Fill" Stroke="Black" StrokeThickness="1"
                                      StrokeDashArray="1.0 2.0"/>
                            </SelectiveScrollingGrid>
                        </Border>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </DataGrid.RowStyle>
    <!-- ... -->
</DataGrid>
