这是我的 XAML
<ListView x:Name="missingVariablesListView" ScrollViewer.CanContentScroll="True" HorizontalAlignment="Left" Height="320" Margin="81,28,0,0" VerticalAlignment="Top" Width="641" ItemsSource="{Binding}">
<ListView.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Vertical">
<StackPanel Orientation="Horizontal">
<TextBlock Text="ComponentID: " FontWeight="Bold" Foreground="Brown" />
<TextBlock Text="{Binding Name}"/>
</StackPanel>
<ItemsControl ItemsSource="{Binding Parameters}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel>
<StackPanel Orientation="Horizontal">
<TextBlock Text="Variable Name: " Foreground="Green"/>
<TextBlock Text="{Binding Name}"/>
<TextBlock Text=" "/>
<TextBlock Text="Variable Value: " Foreground="Blue"/>
<TextBlock Text="{Binding Value}"/>
</StackPanel>
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
<ItemsControl.ItemContainerStyle>
<Style >
<Style.Triggers>
<DataTrigger Binding="{Binding IsMissing}" Value="false">
<Setter Property="UIElement.Visibility" Value="Collapsed"/>
</DataTrigger>
</Style.Triggers>
</Style>
</ItemsControl.ItemContainerStyle>
</ItemsControl>
<TextBlock Text="-----------------------------------------------------------------"/>
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
这是背后的代码
this.missingVariablesListView.DataContext = //Code to fill in the list View
涉及的课程
public class Component
{
private ObservableCollection<ComponentParameter> parameters = new ObservableCollection<ComponentParameter>();
public string Name
{
get;
set;
}
public ObservableCollection<ComponentParameter> Parameters
{
get{return parameters;}
set{parameters = value;}
}
}
public class ComponentParameter
{
public string Name
{
get;set;
}
public string Value
{
get;set;
}
public bool HasErrors
{
get;
set;
}
public bool IsMissing
{
get;set;
}
样本输出(目前)
ComponentID: Component1
--------------------------
ComponentID: Component2
VariableName:Var1 Variable Value:Val1
VariableName:Var2 Variable Value:Val2
-----------------------
ComponentID: Component3
-----------------------
ComponentID: Component4
-----------------------
我想要做的是,每当 itemsControl 中的内部元素的布尔 IsMissing 为真时,我想确保 StackPanel 中的 ComponentID 和 Name 属性(方向为水平)不显示在窗口中,包括子元素。基本上,我试图找到一种方法来排除 isMissing 变量设置为 true 的特定 ComponentID 的整个描述。对此有何建议?
