WPF DataGrid - SelectedItem 在文本外的 FullRow 选择上没有改变
WPF DataGrid - SelectedItem not changing on FullRow selection outside text
我正在构建一个包含高度为 40 的行的数据网格。在行选择上,程序打开一个新选项卡,其中包含特定于该项目的用户控件。
当我单击单元格内容 (Red boxes in this image) 之外的行中的任意位置时,事件会触发,但 'CurrentItem' 不会更新。
基本上,只有单击单元格内容时才会选中该行。有没有其他人处理过这个问题,并对发生的事情有解决方案?
这是我的造型:
<DataGrid Name="MachinesGrid" ItemsSource="{Binding MainData.Machines}">
<DataGrid.Style>
<Style TargetType="DataGrid">
<Setter Property="SelectionMode" Value="Single" />
<Setter Property="SelectionUnit" Value="FullRow" />

<Setter Property="ColumnWidth" Value="Auto" />
<Setter Property="CanUserAddRows" Value="False" />
<Setter Property="Background" Value="{StaticResource BrushBackground}" />
<Setter Property="RowBackground" Value="{StaticResource BrushGreyMid}" />
<Setter Property="AlternatingRowBackground" Value="{StaticResource BrushGreyDark}" />
<Setter Property="GridLinesVisibility" Value="None" />
<Setter Property="ColumnHeaderStyle">

据我所知,您的问题是选择最初是在 DataGridCell
中通过设置
触发的
<Setter Property="VerticalAlignment" Value="Center" />
你的意思是 DataGridCell
应该在 DataGridRow
中垂直居中,这导致一些 space 顶部和底部不属于 DataGridCell
,因此不是触发任何选择。
要解决此问题,您必须将 VerticalAlignment
设置为 Stretch
(默认),但您的内容不再居中,为此您必须覆盖 ControlTemplate
DataGridCell
:
<ControlTemplate TargetType="{x:Type DataGridCell}">
<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="True">
<ContentPresenter VerticalAlignment="{TemplateBinding VerticalContentAlignment}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
</Border>
</ControlTemplate>
现在您可以在 DataGridCell
上设置 VerticalContentAlignment
和 HorizontalContentAlignment
来对齐您的内容。
您的 DataGridCell
-样式应该如下所示
<Style TargetType="DataGridCell">
<Setter Property="VerticalContentAlignment" Value="Center" />
<Setter Property="Foreground" Value="{StaticResource BrushWhite}" />
<Setter Property="Background" Value="Transparent" />
<Setter Property="BorderThickness" Value="0"/>
<Setter Property="FocusVisualStyle" Value="{x:Null}"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type DataGridCell}">
<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="True">
<ContentPresenter VerticalAlignment="{TemplateBinding VerticalContentAlignment}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
