I have a treeview that is populated with a hierarchical list of regions and locations. Each region has its own list of regions and locations - you can think of these as analogous to a folder structure in windows (ie a region is like a folder than can have subfolders and files within it).My code to populate the structure is called only once (I've put in breakpoints and stepped through the code), however my treeview shows two sets of the data. When I query how many nodes there are at the top level of the treeview it tells me there is only one node, but clearly there are two. If I delete the node at position 0 in the list of nodes one copy of the tree disappears but one still remains and it this point the count of nodes in the treeview is reported as zero.
I have a toolbar associated with the treeview which includes buttons to expand all and collapse all using the built in methods of the treeview (expandall and collapseall), and these only act on the first set of nodes and ignore the second set even though I can manually expand and collapse them at run time.I have code in the AfterSelect event of the treeview and this does fire for even the phantom nodes.The other odd thing is that the code to populate the tree assigns a key to each node, and so I would expect the code to fail if it was creating duplicate nodes as it would have duplicate keys
I currently have a procedure that stores the Level, Parent.Level, and Text properties of each TreeNode in a TreeView control in a DataTable.I can't seem to come up with the logic to load this data back into the TreeView from scratch, though.
Below is what i currently have in place which does not work.
Private Sub LoadTree(ByVal table As Data.DataTable)
treeBilling.Nodes.Clear()
For Each row As Data.DataRow In table.Rows

I'm all new to this treeview business. I have a fixed treeview, very simple and basic. Only two levels, parent and child nodes. I just need two things out of this treeview.
1) If parent is checked, check all child nodes.
2) If just one child node is unchecked, uncheck parent node.
That's it! I've been looking for this for 30 mins and I cant find it. Maybe because my vb.net is old, it doesnt seem to be the same as others =/ I'm using vb.net 2003.

I have some operations of Picture Boxes etc being performed. After the user finishes with the formatting, I want to give the user an option to print the work.But its the work is not done on the Rich Text Box but on picture boxes. I am not even sure, how many of the picture boxes would be there after the user finishes the job, since I have provided option for dynamically creating picture boxes as well.
View 3 RepliesI have a treeview that is populated from a HDD folder collection. Its structure is similar to the following (however the structure is dynamic):
My Disk:
|
|--folder1(tag:folder)
| |--subfolder1(tag:folder)

I call the sub as follows:
deleteNode(treeview1.Nodes(0).Nodes)
However, the above is not working properly. It deletes only some nodes and not all the targeted nodes.
I am building a 'shape editor' which looks very similar to the Visual Studio form designer. I have a Toolbox control that holds a few 'Shapes' (such as RectangleShape, EllipseShape, TriangleShape, etc) which the user should be able to drag to the design view ("Canvas") in any MDI form. The Toolbox control is just a TreeView except that I add ToolboxItems to it (which are inherited TreeNodes). This dragging however does not seem to work...

I'm able to drag and drop a node. The treeview is loaded with files and folders on the HD. The tag of the node has the path to the file/folder. [code] I only want to be able to drag a node into a folder and not into a file, as it does with this code.

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 am able to get the pnode added to the TreeView and all the node breakpoints are hit. The problem is that in the TreeView, I am only able to see the parent view arrow, the rest of the name, image, etc. are not getting displayed. It is like this: How can I fix this?
I'd hate to have to create my own control, but will attempt to if it comes to it.
I need to display columns within a TreeView node so I can display specific information about that item within columns.
Think of a ListView as a TreeNode. That's basically what I'm trying to get at.
I'm hoping for a relatively easy solution, but I can't imagine this would be too easy.
I am trying to add nodes to a treeview that come from different databases, but at the moment i am just trying to add the first set from the first database.
The link between the child and the parent is the ID column in the parent nodes access database this number is in a column in the child database called Section, i am trying (unsuccesfully) to use queries and If statements.
I am assigning the ID column from the parent database to the .Tag property of the parent node and then i am trying to use an if statement within the query "asking" if the parentNode.Tag = number in section column Then Add new node, but i haven't done it right. The code is below:
While RetVal3.Read
If RetVal3(0).ToString = SectNode.Tag.ToString Then
Call AddCalcNodes(SectNode)
