hierarchicaldatatemplate

问题 There seems to be a ton of information on HierarchicalDataTemplate, but I have had a hard time finding info specific enough to help me out with hierarchies containing different types. Assuming the following class structure: public class classA { public string name{get;set;} } public class classB { public string name{get;set;} public List<classA> subItems{get;set;} } public class classC { public string name{get;set;} public List<classB> subItems{get;set;} } Now taking into assumption the

问题 I have a Menuitem which is supposed to show a list of quantities as children which show a list of the units defined for this quantity as children. The list of quantities is set in code-behind to the ItemsSource of the MenuItem. <MenuItem Header="common.unitsystem" Name="mnuItemUnits"> <MenuItem.Resources> <DataTemplate DataType="{x:Type guidev:Measurement}"> <StackPanel> <TextBlock Text="Measurement"/> <TextBlock Text="{Binding Name}"/> </StackPanel> </DataTemplate> <HierarchicalDataTemplate

问题 I am only two weeks into WPF so this is probably a trivial question. I have a collection "CellList" which has a few properties I would like to bind to a ToolTip so when I hover over a label information from the current instance of CellList is displayed. How do I do that? I understand simple binding and this maybe simple binding too but I can't wrap my head around it. Below is my XAML for the label. Could someone explain to me how I can accomplish this. <HierarchicalDataTemplate> <ListBox

问题 I want to create a TreeView with MasterDetails on selected Item. The problem is, that no children are displayed in my SelectedItem, even when the parent is expanded. Somehow the HierarchicalDataTemplate seems to get lost. Maybe I am just wrong with the HierarchicalDataTemplate in the <TreeView.ItemTemplate> . Should I start with ItemsPanelTemplate or something similar? Have no clue at the moment. Here is my XAML: <Window x:Class="TreeViewMasterDetails.MainWindow" xmlns="http://schemas

问题 In my TreeView I use two differnt classes for binding. For example, I have a Group what can have ChildGroup and can have Items. Example code of this classes: using System.Collections.Generic; using System.Collections.ObjectModel; namespace WpfApplication1 { public class Group { public Group(string name) { Name = name; items = new ObservableCollection<Item>(); groups = new ObservableCollection<Group>(); } public string Name { get; set; } private ObservableCollection<Item> items; private

问题 I have two identical HierarchicalDataTemplates. The only difference is the DataType of the templates. <HierarchicalDataTemplate DataType="{x:Type Data:OuterType}" ItemsSource="{Binding Items}"> <StackPanel>...</StackPanel> </HierarchicalDataTemplate> <HierarchicalDataTemplate DataType="{x:Type Data:InnerType}" ItemsSource="{Binding Items}"> <StackPanel>...</StackPanel> </HierarchicalDataTemplate> How can I avoid duplicating the contents of the stack panel in both data templates? I considered

问题 I have a list containing objects that follow this structure. This is not the real classes I am working with, but should explain the concept. CLASSES public class BaseType{} public class TypeA : BaseType{} public class TypeB: BaseType { public List<TypeA> TypeAList { get; private set; } } The List that the ItemsControl binds to is a List<BaseType> XAML <ItemsControl> <ItemsControl.Resources> <HierarchicalDataTemplate DataType="{x:Type local:TypeB}" ItemsSource = "{Binding Path=TypeAList}">

问题 So, the following is easy enough in WPF, but how would you do it in Silverlight? Please note that the trick here is to display both Groups, and Entries on the same level. Additonally you dont know how deep the entries are nested, they might be on the first, or the nth level. This is hard in Silverlight because you lack the DataType="{x:Type local:Group}" property in the H.DataTemplate (or any DataTemplate). Building my own custom DataTempalteSelector also didnt work, because the Hierarchial

问题 how can I get the constituent controls making up the TreeViewItem in code if they are inside a hierarichicaldatatemplate? <HierarchicalDataTemplate DataType="{x:Type local:Module}" ItemsSource="{Binding Children}"> <StackPanel Orientation="Horizontal"> <Image Width="16" Height="16" Margin="3,0" Source="Images\module.ico" /> <local:RenamingNode Name="RenamableNode" Text="{Binding Name}" VstaObject="{Binding BindsDirectlyToSource=True}" OnRename="OnRenameOccured" /> </StackPanel> <

问题 The Situation: I have two classes that are represented in a TreeView. DiskSpec and DiskSet. DiskSpec can exist by itself, or it can be a child of DiskSet. I am working on enabling DragDrop functionality so that the user can drag a DiskSpec from the DiskSpec node onto a DiskSet to add it to that DiskSet. Now all is working except for one thing. My DragDropHelper class needs to specify in an ItemsPresenter (or related class) that that control is a drag source or a drop target. My TreeView is
