我看到有方法可以禁用ListView中的選擇，但我還沒有看到TreeView或Grid的任何內容。在TreeView中禁用選擇
我的形式是很基本的，看起來像這樣：
問題是有人可以去點擊其中任何一個標籤，突然它看起來像這樣：
如何禁用此行爲？
<TreeView Focusable="False">
<TreeView.ItemContainerStyle>
<Style TargetType="{x:Type TreeViewItem}">
<Setter Property="Focusable" Value="False"/>
</Style>
</TreeView.ItemContainerStyle>
<TreeViewItem Focusable="False">
<TreeViewItem.Header>Group Header</TreeViewItem.Header>
<TreeViewItem.IsExpanded>true</TreeViewItem.IsExpanded>
<Grid Focusable="False">
<Grid.RowDefinitions>
<RowDefinition></RowDefinition>
<RowDefinition></RowDefinition>
<RowDefinition></RowDefinition>
<RowDefinition></RowDefinition>
<RowDefinition></RowDefinition>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"></ColumnDefinition>
<ColumnDefinition Width="Auto"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Label Content="Message ID">
<Grid.Row>0</Grid.Row>
<Grid.Column>0</Grid.Column>
</Label>
<TextBox Text="{Binding Path=GroupHeader.MessageId}" HorizontalAlignment="Stretch">
<Grid.Column>1</Grid.Column>
<Grid.Row>0</Grid.Row>
</TextBox>
<Label Content="Creation Date">
<Grid.Row>1</Grid.Row>
<Grid.Column>0</Grid.Column>
</Label>
<DatePicker SelectedDate="{Binding Path=GroupHeader.CreationDateTime}">
<Grid.Row>1</Grid.Row>
<Grid.Column>1</Grid.Column>
</DatePicker>
<Label Content="Instructing Agent">
<Grid.Row>2</Grid.Row>
<Grid.Column>0</Grid.Column>
</Label>
<TextBox Text="{Binding Path=GroupHeader.InstructingAgent}">
<Grid.Row>2</Grid.Row>
<Grid.Column>1</Grid.Column>
</TextBox>
<Label Content="Instructed Agent">
<Grid.Row>3</Grid.Row>
<Grid.Column>0</Grid.Column>
</Label>
<TextBox Text="{Binding Path=GroupHeader.InstructedAgent}">
<Grid.Row>3</Grid.Row>
<Grid.Column>1</Grid.Column>
</TextBox>
</Grid>
</TreeViewItem>
<TreeViewItem>
...
</TreeViewItem>
</TreeView>
使用TreeView.ItemContainerStyle只是禁用它在實際的項目頭，而不是在它的內容似乎。
更新：我試着從克里斯·W上的評論和有關設置控件模板的回答表明，使用以下：
<Style x:Key="StretchingTreeViewItemStyle1" TargetType="{x:Type local:StretchingTreeViewItem}">

結果是對TreeViewItem本身的文字不再是可選/不會突出顯示，但其中的內容仍然可以。
我試過設置一切我能想到的Focusable="False"，但那也行不通，所以我開始認爲它不關注焦點在一個項目上。特別是因爲如果你嵌套TreeViews你可以同時選擇一個內部和一個外部項目。
它將在默認控制模板中作爲選擇項目樣式的嵌套ToggleButton上的多觸發器。我似乎無法找到一個默認的WPF樹視圖項目樣式，並且我懶得去製作一個wpf proj只是爲了拉出一個，但如果你想共享一個，很容易發現它在那裏。 –
