我在wpf中使用下面的xaml构建了一个treeview。它是一个结构良好的数据源,我在拖放时遇到了很多麻烦。我尝试了几种方法,都无济于事。任何人都可以告诉我做这种事情的标准程序是什么?WPF Treeview HierarchicalDataTemplate拖放
<TreeView x:Name="_treeView" ItemsSource="{Binding}" Grid.Row="0" Grid.Column="0">
<TreeView.Resources>
<HierarchicalDataTemplate DataType="{x:Type Logic:Statement}"
ItemsSource="{Binding Path=PagedChildren}">
<TextBlock Text="{Binding StatementName}"/>
</HierarchicalDataTemplate>
<HierarchicalDataTemplate DataType="{x:Type Logic:StatementPage}"
ItemsSource="{Binding Path=Children}">
<WrapPanel>
<TextBlock Text="Page: "/>
<TextBlock Text="{Binding PageIndex}"/>
</WrapPanel>
</HierarchicalDataTemplate>
<DataTemplate DataType="{x:Type Logic:StatementFund}">
<Border HorizontalAlignment="Left" VerticalAlignment="Top" BorderBrush="Black" BorderThickness="2" CornerRadius="25">
<WrapPanel Margin="30 0 30 0" Width="150" Height="150" >
<StackPanel>
<TextBlock Text="Fund"/>
<WrapPanel>
<TextBlock Text="Fund: "/>
<TextBlock Text="{Binding FundNumber}"/>
</WrapPanel>
<WrapPanel Margin="10 0 0 0">
<TextBlock Text="{Binding ColumnIndex}"/>
</WrapPanel>
</StackPanel>
</WrapPanel>
</Border>
</DataTemplate>
<DataTemplate DataType="{x:Type Logic:StatementPreviousCycle}">
<Border HorizontalAlignment="Left" VerticalAlignment="Top" BorderBrush="Black" BorderThickness="2" CornerRadius="25">
<WrapPanel Margin="30 0 30 0" Width="150" Height="150" >
<StackPanel>
<TextBlock Text="Previous Cycle"/>
<WrapPanel>
<TextBlock Text="Fund: "/>
<TextBlock Text="{Binding FundNumber}"/>
</WrapPanel>
<WrapPanel Margin="10 0 0 0">
<TextBlock Text="{Binding ColumnIndex}"/>
</WrapPanel>
</StackPanel>
</WrapPanel>
</Border>
</DataTemplate>
</TreeView.Resources>
</TreeView>
问题出现在TreeView本身,我如何在mousebutton down(在选择节点之前)时获得selectedNode。此外,绑定使用正常的方式搞砸了。 – Dested 2009-11-25 02:05:32
您在wpftutorial.net上列出的网站确实为我省去了。 =) – 2010-10-10 07:53:52
