I am trying to populate a treeview with data from and xml document.
The loading of xml is no problem i have done that a million times over, the problem seems to be able to fill the treeview with content. My problem is this: I have a treeview with this in it:
-Race
|-HQ
|-TROOP
|-ETC...
now... the program loads all units from xml. so when it encounters for instance a unit with a "<class>" tag containing HQ, how do i make it put it in the HQ node? I cant make it put new nodes into existing ones, only into new ones....

View 1 RepliesI've made a browser project and beyond making it a default browser, I am having a problem with the Favorites feature TreeView control saving, loading and repopulating it with the users data. It's tough finding the correct code as there are so many variations of this control in various languages, but I did find sample code for loading and populating the TreeView with a text file using tabs to signify the node structure in VB.Net.

This is somewhat of a multi part question, let me start off by explaining what I'm trying to do. I have an organized folder system with data files in them. Each folder has a set structure to their naming, and can contain sub folders and files. It will be a jagged directory system. I'm trying to import their structure into a TreeView. I have the workings of a recursive system that adds all files and folders into a ViewTree, however they aren't organized by parent/child.
So I get this...
-C:Temp
-C:TempData
-C:Tempfile1.txt
-C:Tempfile2.txt
-C:TempDatafile3.txt
-C:TempDatafile4.txt
etc........
How would I go about parsing the directory paths, and include them into a parent/child relationship... looking like this
+Temp
--file1.txt
--file2.txt
-+Data
---file3.txt
---file4.txt
Also I when the line item is selected, I need to know which file is selected so I can use it's full path to call up data (using an API) based upon the it's full root path.
im using vs2010 and SQL server 2005. what is the best and fastest way to load large volume of data into treeview
View 6 RepliesI have an Active Directory browser written in vb.net 2008 that allows an end user to visually browse AD. Currently it displays the full DN for each child and what I want is to display just the name of the OU. Something tells me I would use the Tag() function but after playing with it, I just couldn't figure it out. All I removed was our internal domain name.
Would someone like to review what I have now and offer some ideas on what I would change to alter how the tree is viewed while retaining funuctionality?

I would like to use a treeview control to display related data as Folders(Level0), Projects(Level1), Drawings(Level2). So far I don't have a problem reading data from a database, creating classes to hold the data and displaying the tree from the class data. I have created (3) contect menu strips, one for each level of the tree to perform various tasks. Each menu has an ADD option to either add a folder, add a project or add a drawing.My problem is as follows...After I add the node, in the correct location, I would like to have it set in the BeginEdit mode.
Dim oNode As New TreeNode
oNode = TreeView1.SelectedNode.Nodes.Add(sNextID, "New Project")
oNode.ImageIndex = 1
TreeView1.Refresh()
[code]....
After this code runs, the node.Text changes back to "New Project". As you can see, I added a few debug.print statements to try to see what is going on. It really blew my mind to see that the entire tree printed in the immediate window.I have already created a work around for this, but is isn't really the way I'd like to see the program run.
i have a treeview say TV1 and another Treeview Say TV2.. Now TV1 Contains all nodes for user rights. and i want to add to tv2 only selected nodes.Like TV1 is
Node 1
....Child of Node 1 (Level 2)
.........Child of Child of Node 1 (Level 3)
what i want is that when i select Level3 Node it should chek TV2 for the parent of this node. if parent exist it should add the node under the same parent. if parent does not exist it should check for Level 1 Node and if it exist it should add Level 2 Node and then Level 3 Node. Otherwise it should add Level 1 , Level 2 and then Level 3 Nodes in order.
I have a class, let's call MyClass. In this class, I have a TreeView property let's call myTreeView..In my code, I populate the Nodes of this TreeView so I can use it later on.Then, when it's time to actualy use it, I haven't been able to take all the nodes from myClass and put them in a Tree View Control on my form.[code]The weird thing is that when debugging, the TreeView in MyClass is well populated with the proper values and in the loop, newNode isn't empty, there's actually something but for some reason it's not showing anything.

How can i add Columns to Treeview so that first column should be as tree and rest are like listview or Listbox.
View 12 RepliesThe TreeView uses in its underlying implementation the TreeNodeCollection. The TreeNodeCollection in almost every overload of the add method asks for a key.It also implements indexOfKey and ContainsKey yet there appears to be no way to determine the key of a node from the node itself or from any of the events you would typically use such as TreeView_AfterSelect().
Am I correct or is there in fact someway to retrieve the key from a node or event which I have overlooked? And assuming I am correct. Why on earth was it implemented in such a way? The only thing I could think of was that perhaps TreeNodeCollection.Key is deprecated? But I see no mention of this...
PS: I am aware of the TreeNode.Tag property and how it can be used to the same effect.
