所以我有一个与this question相同的问题。 但是，此问题的解决方案似乎是Code-Behind（已有4年历史了），但我使用的是MVVM。时间可能带来了更好的解决方案。
有人知道在选中DataGridRow后双击该作品吗？
这是我的XAML：
<DataGrid x:Name="ContactsResult"
AlternatingRowBackground="Transparent"
AutoGenerateColumns="False"
BorderBrush="{StaticResource DarkBlueBrush}"
BorderThickness="1"
CanUserAddRows="False"
FontFamily="{StaticResource DefaultFont}"
GridLinesVisibility="None"
HeadersVisibility="Column"
IsReadOnly="True"
ItemsSource="{Binding Results, Mode=TwoWay}"
SelectedItem="{Binding SelectedItem, Mode=TwoWay}"
>
<DataGrid.InputBindings>
<MouseBinding Gesture="LeftDoubleClick"
Command="{Binding DetailsCommand}"
CommandParameter="{Binding ElementName=ContactsResult, Path=SelectedItem.ContactId}"
/>
</DataGrid.InputBindings>
<DataGrid.Columns>
<DataGridTextColumn x:Name="contactLastNameColumn"
Binding="{Binding Name_LastSufFirstMidSal}"
ElementStyle="{StaticResource dgCellPadding5}" Header="Contact Name"
Width="Auto"
/>
<DataGridTextColumn x:Name="companyNameColumn"
ElementStyle="{StaticResource dgCellPadding5}" Header="Company Name"
Width="Auto"
/>
<DataGridTextColumn x:Name="CityColumn"
Binding="{Binding MailingAddress.City}"
ElementStyle="{StaticResource dgCellPadding5}" Header="Mailing City"
Width="Auto"
/>
<DataGridTextColumn x:Name="StateColumn"
Binding="{Binding MailingAddress.StateOrProvince}" ElementStyle="{StaticResource dgCellPadding5}" Header="Mailing State"
Width="Auto"
/>
</DataGrid.Columns>
</DataGrid>

<Style x:Key="dgCellPadding5" TargetType="{x:Type TextBlock}">
<Setter Property="Margin" Value="5" />
</Style>

以下针对.NET 4.7.1的示例触发了双击命令（无论选择状态如何）。我已经从上面包含了您引用的样式。您的代码与此不同吗？

我使用棱镜框架，这是我的代码：
xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"
<controls:CustomDataGrid Grid.Row="2"
SelectedItem="{Binding ModelItem}"
ItemsSource="{Binding ModelList}"
IsReadOnly="True"
Style="{StaticResource DataTriggerDataGridStyle}">
<i:Interaction.Triggers>
<i:EventTrigger EventName="MouseDoubleClick">
<i:InvokeCommandAction Command="{Binding BtnNoticeViewCommand, IsAsync=True}"/>
</i:EventTrigger>
</i:Interaction.Triggers>

因此，为了达到我的目标，我决定走另一条路。
首先，我从Grid开始，并使用了Grid.IsSharedSizeScope =“ True”属性。在此网格中，我创建了一个网格和一个ItemsControl（在数据模板中带有一个网格）。这给了我一个数据网格的外观。
第二，在项控件中，我向每个项添加了InputBindings以实现所需的行为。这是我想出的：
<Border Grid.Row="2"
BorderBrush="{StaticResource BackgroundTitleBarBrush}"
BorderThickness="1"
Visibility="{Binding ResultGridVisible, Converter={local:BooleanToVisibilityValueConverter}, ConverterParameter=True}"
>
<Grid Background="White"
Grid.Row="2"
Grid.IsSharedSizeScope="True"
>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Border BorderBrush="{StaticResource SeperatorDarkBlueBrush}"
BorderThickness="0 0 0 1"
Margin="5 0"
Padding="3 5"
Grid.Row="0">

<ColumnDefinition SharedSizeGroup="A" Width="150"/>
<ColumnDefinition SharedSizeGroup="B" Width="200"/>

<ColumnDefinition SharedSizeGroup="E" Width="100"/>
<ColumnDefinition SharedSizeGroup="F" Width="50"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>

<RowDefinition Height="Auto"/>
