TreeView - Display Nodetext In DrawNode-Event?
Oct 22, 2009
i do have a treeview with it's property "DrawMode" set to "OwnerDrawText" because sometimes the display nodetext has to appear in bold format. Generally, thinks work fine, but after refreshing the treeview, the nodetext appears twice! Not only does it appear where the nodes are, but also on the upper left of the treeview control. Before reloading the nodes into the treeview, I use the treeview.clear-method to get rid of the old nodes in the treeview.
Here is the code of the drawNode-Event:
Private Sub TreeViewExt_DrawNode(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DrawTreeNodeEventArgs) Handles TreeViewExt.DrawNode

I'm facing a problem with Treeview, I'm using it as a menu in a app, but I just can't find anything related on how to change the hottracking event, like the font color, or the background color once an item is selected.

I have an explorer-like form with a TreeView and a ListView. I have finally figured out how to populate the the ListView based on the selected node, but when I am debugging, I click on a node, and the ListView doesn't change. I have to single click twice on the node for it to work. What could be my issue? I have included the code from my sub below.
Private Sub TreeView1_NodeMouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseClick
Dim newSelected As TreeNode = e.Node
ListView1.Items.Clear()
Dim subItems() As ListViewItem.ListViewSubItem

I'm looking to populate a treeview control with nodes, at RUNTIME. When the user clicks on the node, it will open up a form to display the data for the device represented by the node.There are three groups of nodes. Each group has its own form that it uses. For example:
-Root
---Group 1
------Device 1

I have used the TreeView and populated the list using the following code:
m_strStation = cboStation.SelectedItem
For Each strDir As IO.DirectoryInfo In New IO.DirectoryInfo(m_strPath & m_strStation).GetDirectories()
trvFolders.Nodes.Add(strDir.Name)
Next
The TreeView populates and every folder is visible, however the folder names consist of:Place #. Name the problem I am having is that the number range is 1 - 16 and the order in which the folders are being displayed is 1, 10, 11, ..., 15, 16, 2, 3, ..., 8, 9 I am looking for the folders to be listed in true numerical order e.g. 1, 2, 3, ..., 14, 15, 16

I have a tree view with checkboxes. When a user checks an item in the tree, all items below it in the tree should be checked automatically to match the parent. The same is true is a user unchecks an item. That's been reasonably easy to implement using the after check event:-
Private Sub tvwUserGroups_AfterCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles tvwUserGroups.AfterCheck
If Not m_Isloading _

I'd like to use a TreeView control to display database data in a windows form with VB2008. All the information what I found is related to a website design, but I'm working on a database program (sql2005), where I'd like the user to see the structure what he/she make up with a TreeView like control. Just something like that when you explore your hard disk. How can I do that?

I'm just starting out at vb.net but have done programming before. i am trying to use a treeview to display information in a seperate table on the same form dependant on which nod of the tree is clicked. Secondly is it possible to import the information from an excel spreadsheet or does the information have to come from an access table.

I have a custom contro which inherits directly from Treeview. Is there any way to handle some event related to when the TreeView Scrollbar appears (it does this when the height of the stack of visible nodes exceeds the height of the control) or "disappears"?
I realize if could set up a function which checks the ItemHeight * Nodes.Count, and compares this to the control height. However, this seems clumsy. I have been exploring the object browser (and anylized TreeView with Reflector) and have not found what I am looking for. If there is a way to access the ScrollBar Property at ALL within TreeView, I have not found it.

I'm in need of a custom control that will allow me to do something like the attached image. It's basically a TreeView with the exception of having a row of PictureBoxes for each child node. I'd be happy with a ListView that could do this even. I tried it briefly with a DataGridView with ImageColumns but the "look" wasn't quite what I was after. I'd like the "Parent Node" text to be situated above the row of images and just can't seem to find a control that will allow this.

I have a treeview, it lists all folders and subfolders and files within each folder. Now, I want to display each file / folders associated icon. I am using the SHGetFileInfo API, it works sort of, what I mean by sort of is, that my treeview doesn't update after each folder / file. Sometimes it keeps giving me the Recycle Bin's icon at different folders.

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 seen lots of examples with a treeview to list folders then display the folders context in a listview.
But what id like is a checked treeview, that not only displays the folder list, but the actually folder contents as well.

I want to write an event that will simply display something when it is raised. I have never really worked with event driven programming before and am just trying to get a simple example working. It is not yielding any errors, but when I switch to debug mode I can see that the event it not raising correctly.
