treeviewitem

I am creating a TreeView at runtime. It has several nodes(TreeViewItem), each one having a name. Initially it is collapsed. A separate comboBox displays Names of all TreeViewItem. I have to highlight a TreeViewItem based on the Name selected. I am using a recursive function and gets the TreeViewItem container like this: if (parent.ItemContainerGenerator.Status != GeneratorStatus.ContainersGenerated) continue; TreeViewItem container = parent.ItemContainerGenerator.ContainerFromItem(child).As<TreeViewItem>(); but it is parent.ItemContainerGenerator.Status = GeneratorStatus.NotStarted for all the

This time, my question is as simple as it sounds... how do you get text to wrap in a WPF TreeViewItem ? I have a simple HierarchicalDataTemplate with just one TextBlock in it. <TextBlock Text="{Binding Value}" TextWrapping="Wrap" /> The text does not wrap.

This question is a follow up to this question.

I have decided to explore the List option due to my lack of experience with ModelView . In my research I've learned that Lists of TreeViewItems are a little different, because you

This is my next question following Hook into a child class SysTreeView32 of VBE window I can access the SysTreeView32 now but I cant access the child node of the hNode. I have tried many variations and been reading about it for the past 2 hours but I can't work it out. Is this even possible? I really want to avoid the mouse_event and clicking because of different window dimensions and position but if thats the only way then I will try to implement that. heres the code: Option Explicit Private Const TVE_COLLAPSE = &H1 Private Const TVE_COLLAPSERESET = &H8000 Private Const TVE_EXPAND = &H2

Is there a way to make the treeview show lines connecting items when we expand them? Thanks! You'd have to replace TreeViewItem control template to achive that. Look at this thread on MSDN there should be all information you need. 来源： https://stackoverflow.com/questions/1222591/show-treeview-items-connected-with-lines
