WPF 툴킷 PropertyGrid가 확장 :</p> <pre><code>propertyItem.Visibility = Visibility.Collapsed; </code></pre> <p>이 전체 카테고리를 숨길 수 있나요 :이 코드를 사용하여 특정 속성을 숨길 빈 카테고리

Question

숨기기? 이제 해결 방법은 다음과 같습니다.

if (propertyItem.Category == "MyCategory") 
{ 
    propertyItem.Visibility = Visibility.Collapsed; 
} 

범주의 모든 항목을 숨기면 머리글이 항상 표시됩니다. 카테고리의 헤더를 숨기는 방법이 있습니까?

Answer 1

목표가 너무 쉽지는 않지만 도달하는 것이 불가능하지는 않습니다. 당신이 볼 수 있듯이

<local:ItemsVisibleConverter x:Key="ItemsVisibleConverter" /> 

<Style x:Key="CustomPropertyItemGroupContainerStyle" TargetType="{x:Type GroupItem}"> 
    <Setter Property="Control.Template"> 
     <Setter.Value> 
      <ControlTemplate> 
       <Border> 
        <Expander Style="{StaticResource ExpanderStyle}" Header="{Binding Name}" IsExpanded="True"> 
         <ItemsPresenter /> 
        </Expander> 
       </Border> 
      </ControlTemplate> 
     </Setter.Value> 
    </Setter> 

    <Style.Triggers> 
     <DataTrigger Binding="{Binding Path=Items, Converter={StaticResource ItemsVisibleConverter}}" Value="False"> 
      <Setter Property="Visibility" Value="Collapsed" /> 
     </DataTrigger> 
    </Style.Triggers> 
</Style> 

, 그것은 간단한 계산기 사용 : 우리는 눈에 보이는 특성이없는 카테고리 숨겨진 만들기위한 우리의 스타일을 만드는 데 필요한 모든 먼저

public class ItemsVisibleConverter : IValueConverter 
{ 
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture) 
    { 
     IEnumerable itemCollection = value as IEnumerable; 
     if (itemCollection != null) 
     { 
      foreach (PropertyItem propertyItem in itemCollection) 
      { 
       if (propertyItem.Visibility == Visibility.Visible) 
       { 
        return true; 
       } 
      } 
     } 

     return false; 
    } 

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) 
    { 
     throw new NotSupportedException(); 
    } 
} 

및 다른 자원 (I) ILSpy를 사용하여 표준들에서 그들을 복사 :

<SolidColorBrush x:Key="GlyphBrush" Color="#FF31347C" /> 

<ControlTemplate x:Key="ExpanderToggleButton" TargetType="{x:Type ToggleButton}"> 
    <Grid> 
     <Rectangle Name="Rectangle" Margin="0,0,0,0" Fill="#00FFFFFF" /> 
     <Path Name="Up_Arrow" HorizontalAlignment="Center" VerticalAlignment="Center" Fill="{StaticResource GlyphBrush}" Data="M0,0L4,4 8,0z" RenderTransformOrigin="0.5,0.5"> 
      <Path.RenderTransform> 
       <TransformGroup> 
        <ScaleTransform ScaleX="1" ScaleY="1" /> 
        <SkewTransform AngleX="0" AngleY="0" /> 
        <RotateTransform Angle="-90" /> 
        <TranslateTransform X="0" Y="0" /> 
       </TransformGroup> 
      </Path.RenderTransform> 
     </Path> 
     <Path Name="Down_Arrow" Visibility="Collapsed" HorizontalAlignment="Center" VerticalAlignment="Center" Fill="{StaticResource GlyphBrush}" Data="M0,4L4,0 8,4z" RenderTransformOrigin="0.5,0.5"> 
      <Path.RenderTransform> 
       <TransformGroup> 
        <ScaleTransform ScaleX="1" ScaleY="1" /> 
        <SkewTransform AngleX="0" AngleY="0" /> 
        <RotateTransform Angle="135" /> 
        <TranslateTransform X="0" Y="0" /> 
       </TransformGroup> 
      </Path.RenderTransform> 
     </Path> 
    </Grid> 
    <ControlTemplate.Triggers> 
     <Trigger Property="ToggleButton.IsChecked" Value="true"> 
      <Setter TargetName="Down_Arrow" Property="UIElement.Visibility" Value="Visible" /> 
      <Setter TargetName="Up_Arrow" Property="UIElement.Visibility" Value="Collapsed" /> 
      <Setter TargetName="Down_Arrow" Property="UIElement.OpacityMask" Value="#FF000000" /> 
     </Trigger> 
    </ControlTemplate.Triggers> 
</ControlTemplate> 

<Style x:Key="ExpanderStyle" TargetType="{x:Type Expander}"> 
    <Setter Property="Control.Padding" Value="0" /> 
    <Setter Property="Control.Background" Value="#FFF0F0F0" /> 
    <Setter Property="Control.Template"> 
     <Setter.Value> 
      <ControlTemplate TargetType="{x:Type Expander}"> 
       <Grid> 
        <Grid.RowDefinitions> 
         <RowDefinition Height="Auto" /> 
         <RowDefinition Name="ContentRow" Height="*" /> 
        </Grid.RowDefinitions> 
        <Border Name="Border" Background="{TemplateBinding Control.Background}" BorderBrush="#FFF0F0F0"> 
         <Grid> 
          <Grid.ColumnDefinitions> 
           <ColumnDefinition Width="20" /> 
           <ColumnDefinition Width="*" /> 
          </Grid.ColumnDefinitions> 
          <ToggleButton Template="{StaticResource ExpanderToggleButton}" OverridesDefaultStyle="True" IsChecked="{Binding Path=IsExpanded, Mode=TwoWay, RelativeSource={RelativeSource TemplatedParent}}" /> 
          <ContentPresenter Grid.Column="1" Margin="1" RecognizesAccessKey="True" ContentSource="Header" TextElement.FontWeight="Bold" /> 
         </Grid> 
        </Border> 
        <Border Name="ExpandSite" Visibility="Collapsed" Grid.Row="1" Background="{x:Static SystemColors.ControlBrush}" Padding="10 0 0 0"> 
         <Border BorderThickness="0" Margin="0" Padding="0" VerticalAlignment="Stretch" HorizontalAlignment="Stretch"> 
          <ContentPresenter HorizontalAlignment="{TemplateBinding Control.HorizontalContentAlignment}" Margin="{TemplateBinding Control.Padding}" VerticalAlignment="{TemplateBinding Control.VerticalContentAlignment}" Focusable="False" /> 
         </Border> 
        </Border> 
       </Grid> 
       <ControlTemplate.Triggers> 
        <Trigger Property="Expander.IsExpanded" Value="True"> 
         <Setter TargetName="ExpandSite" Property="UIElement.Visibility" Value="Visible" /> 
        </Trigger> 
       </ControlTemplate.Triggers> 
      </ControlTemplate> 
     </Setter.Value> 
    </Setter> 
</Style> 

이제 우리는 t에 우리의 스타일을 설정하기위한 PropertyGrid 제어를 확장 할 필요가 그는 PropertyGrid에 포함 PropertyItemsControl :

public class PropertyGrid : Xceed.Wpf.Toolkit.PropertyGrid.PropertyGrid 
{ 
    public GroupStyle GroupStyle 
    { 
     get; 
     set; 
    } 

    public override void OnApplyTemplate() 
    { 
     base.OnApplyTemplate(); 

     PropertyItemsControl propertyItemsControl = 
      Template.FindName("PART_PropertyItemsControl", this) as PropertyItemsControl; 
     propertyItemsControl.GroupStyle.Clear(); 
     propertyItemsControl.GroupStyle.Add(GroupStyle); 
    } 
} 

그래서 당신의 XAML은 내가 당신을 도울 수 있기를 바랍니다

<local:PropertyGrid x:Name="pg"> 
    <local:PropertyGrid.GroupStyle> 
     <GroupStyle ContainerStyle="{StaticResource CustomPropertyItemGroupContainerStyle}" /> 
    </local:PropertyGrid.GroupStyle> 
</local:PropertyGrid> 

될 것입니다.
