大家好,我在解决方案上使用带有 mvvm 的 WPF,但我遇到了一个问题。我有我在 viewModel 上使用的这个对象:
public class SuperCharacter : INotifyPropertyChanged
{
public List<Character> Characters { get; set; }
public string Name { get; set; }
private Character charactersExp;
private const string currentCharacterExpandedString = "CurrentCharacterExp";
public Character CurrentCharacterExpanded
{
get { return this.charactersExp; }
set
{
this.charactersExp = value;
this.OnPropertyChanged(currentCharacterExpandedString);
}
}
public string CalcSize { get; set; }
public void OnPropertyChanged(string propertyName)
{
if (this.PropertyChanged != null)
{
this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
}
public event PropertyChangedEventHandler PropertyChanged;
}
我有这样的看法:
Window.Resources>
<DataTemplate x:Key="TrackPointUserSavedSearchDtoTemplate" DataType="{x:Type src:Character}">
<StackPanel >
<TextBlock x:Name="caption" Margin="1"
Text="{Binding First}" MaxWidth="{Binding ElementName=image, Path=ActualWidth}" MaxHeight="40" />
</StackPanel>
</DataTemplate>
<DataTemplate x:Key="DynamicUserSaveSearchesTemplate" DataType="{x:Type src:Character}">
<ContentPresenter x:Name="content" ContentTemplate="{StaticResource TrackPointUserSavedSearchDtoTemplate }"/>
</DataTemplate>
<DataTemplate x:Key="IconoTrackPointUSTemplate" DataType="{x:Type src:SuperCharacter}">
<ScrollViewer Grid.Row="2" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto">
<Expander Height="180" Margin="12,0,0,-127" >
<Expander.Header>
<Binding Path="Name"></Binding>
</Expander.Header>
<ListView Name="ProblemListView" HorizontalContentAlignment="Stretch" ItemsSource="{Binding Characters}" SelectedItem="{Binding CurrentCharacterExpanded}" ItemTemplate="{StaticResource DynamicUserSaveSearchesTemplate}" Panel.ZIndex="20">
</ListView>
</Expander>
</ScrollViewer>
</DataTemplate>
<DataTemplate x:Key="DynamicTrackPointUSTemplate" DataType="{x:Type src:SuperCharacter}" >
<ContentPresenter x:Name="content" ContentTemplate="{StaticResource IconoTrackPointUSTemplate }"/>
</DataTemplate>
</Window.Resources>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="42"></RowDefinition>
<RowDefinition Height="Auto"></RowDefinition>
</Grid.RowDefinitions>
<Label Content="Entitty's TrackPoint list:" Margin="12,5,76,9" Name="labelName" />
<ListView Grid.Row="1" ItemsSource="{Binding SuperCharacters}" SelectedItem="{Binding CurrentSuperCharacterExpanded}" ItemTemplate="{StaticResource DynamicTrackPointUSTemplate}">
</ListView>
<Grid/>
问题是当我展开扩展器时,Listview 调用 ProblemListView 中的元素位于下一个扩展器下方。
我想知道如何使这个扩展列表看起来正确?如果我展开扩展器,problemListView 会正确显示。
请记住,列表是动态的,可以有不同数量的元素
