我有一个树视图,我需要将所选节点的字体设置为粗体..如果节点没有任何子节点,它可以正常工作.但是如果选择了具有子节点的节点,则子节点也显示为粗体.

使用以下XAML:

<TreeView.ItemContainerStyle>
 <Style TargetType="TreeViewItem">
  <Style.Triggers>
   <Trigger Property="IsSelected" Value="True">
    <Setter Property="FontWeight" Value="Bold"></Setter>
   </Trigger>
  </Style.Triggers>
 </Style>
</TreeView.ItemContainerStyle>

我有两个单选按钮用作使用MVVM的UI中的radioButton List.当第一次加载用户控件时,选择一个单选按钮,并在UI中显示相关控件...现在,当我更改单选按钮时,UI不会更新.

以下是XAML示例:

<Label Grid.Column="0" Grid.Row="3" Content="Exchange Details:" Margin="3" VerticalContentAlignment="Center" Style="{StaticResource NormalLabelStyle}"></Label>
 <Grid Grid.Column="1" Grid.Row="3" Width="200">
  <Grid.ColumnDefinitions>
   <ColumnDefinition Width="Auto"/>
   <ColumnDefinition Width="20"/>
  <ColumnDefinition Width="Auto"/>
 </Grid.ColumnDefinitions>
<RadioButton GroupName="rdoExchange" Content="Basic" IsChecked="{Binding Path=ExchangeDetailsBasic}"  Grid.Column="0" VerticalContentAlignment="Center" VerticalAlignment="Center"></RadioButton>
<RadioButton GroupName="rdoExchange" Content="Advanced" IsChecked="{Binding Path=ExchangeDetailsAdvanced}" Grid.Column="2" VerticalContentAlignment="Center" VerticalAlignment="Center"></RadioButton
 </Grid> 

 <Label Grid.Column="3" Grid.Row="0" Content="Number of Mailbox Profiles:" VerticalContentAlignment="Center" Style="{StaticResource NormalLabelStyle}" Visibility="{Binding Path=IsAdvanced}" ></Label>
 <telerik:RadNumericUpDown Grid.Column="4" Grid.Row="0" Margin="3" Value="{Binding Path=NumberofMailboxProfiles}" IsInteger="True" Minimum="1" Maximum="4"  HorizontalAlignment="Left" Visibility="{Binding Path=IsAdvanced}">< /telerik:RadNumericUpDown>

下面是我的ViewModel代码:

 private enum ExchangeDetails{
        Basic,
        Advanced
 }

 private bool isBasicMode = true;
