I have three treeViews that have the same data loaded to them when a form is loaded. I can write the data in three different functions, but that seems like duplicating a lot of work. How can I load each treeView with the same data. So far I have tried the following and it does not work correctly. SecondRowNodes is a set of nodes I have l...
I've got a tree view that can be anywhere from 1 level deep to nearly 6. Each node can be just a few letters or a couple of words totalling up to 20-30 characters. How do I find the largest width of one of the node's text and add its depth offset to set the width of the treeview so it doesn't go through my borders? If I need to add mor...
I need to be able to disable some of the checkboxes in a TreeView control of a WinForms application, but there's no such functionality built-in to the standard TreeView control. Of course, I googled for a solution, but found nothing I would be comfortable using. Does anyone have a simple and robust solution? ...

To store an object (say, an instance of a class) in a TreeViewItem, I am currently storing the object in the TreeViewItem's Header and then overriding the ToString method of that class, so that it displays the correct string header; I then cast the object back during an event. Is this the correct way to achieve this sort of thing, or ...
With regards to a question I posted earlier on (WPF: Correctly storing an object in a TreeViewItem) Is it possible to have nested HierarchicalDataTemplates in a TreeView?

I'm trying to put a TreeView inside a ComboBox in WPF so that when the combo box is dropped, instead of a flat list the user gets a hierarchical list and whatever node they select becomes the selected value of the ComboBox. I've searched quite a bit for how to accomplish this but the best I could find was only peices of potential soltui...

I wish to minimize my server-client trips in this application and want to update the TreeView control through the Javascript. I am guess that the autopostback will have to be set to False. After the data is entered and the tree is ready to be saved, I will need to access the TreeView control on the server side in order to save it. Do...
What would be the advisable thing to do to maximize the performance while using TreeView? By maximize the performance, i mean minimize the number of trips between client to server, ie postbacks. Would that mean then, that most of my Business logic will sit in the Javascript? What would be the compromise here? I am talking about ASP.n...
