我有一个KeyValuePair。起初我只将Value Part绑定到我的Datatemplate中的TreeView。在这种情况下,绑定无法正常工作,但层次结构模板选择正确。
有没有办法通过KeyValuePair的DataType语法选择正确的Datatemplate?
使用的TreeView:
<TreeView Margin="5" Grid.RowSpan="2" Grid.Row="0" Name="tvw_mainMenu" Style=" {DynamicResource NavigationTree}" ItemsSource="{Binding Values}"/>
DataContext(代码隐藏):
mainwindow.DataContext = _myObservableDictionary;
使用过的模板
<HierarchicalDataTemplate DataType="{x:Type local:Scanners}" ItemsSource="{Binding Values}">
<TextBlock Text="Scanner" FontStyle="Italic"/>
</HierarchicalDataTemplate>
<HierarchicalDataTemplate DataType="{x:Type local:Scanner}">
<StackPanel Orientation="Horizontal">
<Image Width="16" Height="16" Margin="3,0" Source="/Resources/Icons/scanner.png" />
<TextBlock Text="{Binding SourceName}" FontStyle="Italic"/>
</StackPanel>
</HierarchicalDataTemplate>
<HierarchicalDataTemplate DataType="{x:Type local:FieldInformations}" ItemsSource="{Binding Values}">
<TextBlock Text="Felder" FontStyle="Italic"/>
</HierarchicalDataTemplate>
<HierarchicalDataTemplate DataType="{x:Type local:FieldInformation}">
<StackPanel Orientation="Horizontal">
<Image Width="16" Height="16" Margin="3,0" Source="/Resources/Icons/textfield.png" />
<TextBlock Text="{Binding Caption}" FontStyle="Italic"/>
</StackPanel>
</HierarchicalDataTemplate>
<HierarchicalDataTemplate DataType="{x:Type local:Sheets}" ItemsSource="{Binding Values}">
<TextBlock Text="Seiten" FontStyle="Italic"/>
</HierarchicalDataTemplate>
<HierarchicalDataTemplate DataType="{x:Type local:Sheet}">
<StackPanel Orientation="Horizontal">
<Image Width="16" Height="16" Margin="3,0" Source="/Resources/Icons/page_green.png" />
<TextBlock FontStyle="Italic"/>
</StackPanel>
</HierarchicalDataTemplate>
