I have a WinForm TreeView Control that displays the Parent Child relationship of CaseNotes(I know that means nothing to most of you but it helps me visualize the answers). I have a DataTable of the CaseNotes that I need to display. The Parent/Child is defined as: If the row has a ParentNoteID then it is a childNode of that note other...
Here is what I am trying to do. I have a TreeView server side control (asp.net 2.0) and I need the user to be able to add nodes to it, then after all the nodes desired are added, the data should be saved to the database.

After a node's label is edited in the tree I try to resort the nodes to place the updated item in the right position. I do this by calling .Sort in AfterLabelEdit event handler which causes an infinite loop. How can I resort the nodes in a treeview after a label has been changed? ...
Hi, I have an external datasource that implements IHierarchicalEnumerable. I'm trying to use that datasource for my TreeView, but I can't find a way to specify the images and individual navigation urls the control should render (there is some business logic there). The examples I have seen all assume the Url and the Name and Image fiel...

I'm working on some application, that uses a TreeView control to represent business objects. Currently the link between business objects and TreeNodes is maintained through the Tag property of the TreeNode. Im not very happy with this, because I think the link is not "tight" enough. For example there could be an TreeNode object without a...
When I select an item on my treeview, there is a notable time gap from my viewmodel class being instantiated to the view refreshing and the treeview node being hi-lit. I need to show a wait cursor during this time - I've tried wrapping the code that instantiates my viewmodel class, but the cursor is back to an arrow a couple of seconds...
How can one easily iterate through all nodes in a TreeView, examine their .Checked property and then delete all checked nodes? It seems straightforward, but you aren't supposed to modify a collection through which you are iterating, eliminating the possibility of a "foreach" loop. (The .Nodes.Remove call is modifying the collection.) ...
I'm in a situation where I need to display a tree. However some of the nodes have 35000 child nodes (direct childs!). This of course is way to slow in terms of usability. I'd rather see that the tree loads only those nodes that are visible in the browser viewport. Such trees exist for WinForms and C++, does any of you know if such a ...

I'm using a TreeView along with a HierarchicalDataTemplate to display a Hierarchical listing returned from a webservice. Depending on search criteria, this listing can get to be very long and several nested levels deep. It would be useful to display a "map" of sorts to the user so that they can see where in this listing they are relati...
In Silverlight 3 I have a TreeView bound to an ObservableCollection in my ViewModel. The items are formated with a Hierarchical Data Template. When the collection is populated from a WebService and the TreeView displays that collection, it scrolls to the bottom of the list. How would I go about finding a particular item that might b...
I have a TreeView control in a Winforms app, and basically the objective is to display a form that contains a TreeView control, and I want to display the form with a node opened (easy - EnsureVisible) and selected.
