If I will select Parent nodes then how I can display in ListView of particular child nodes? Also when I click on root node then how I can display only all parent nodes in ListView?
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 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 have been playing with, and researching, this all day and can't figure it out. I have a Windows Explorer style form with a TreeView and a ListView. I've populated the TreeView with directories and when a node is selected, the ListView fills with the contents of the directory associated with that node. No problem there, but I want to be able to select a directory in the ListView and automatically select the associated node in the TreeView, just like it works in Windows Explorer. All the information I've found online tells me how to populate the ListView from the TreeView, but I haven't found any good examples of how to populate the TreeView from the ListView.

how to add treeview nodes and sub sub nodes using functions
View 1 RepliesI have a form with a treeview and a listview. The treeview lists the folders on your system and listview shows the files in the selected folder, similar to windows explorer. I have a delete button for deleting files.
Dim i As Integer
For i = 0 To lv1.SelectedItems.Count - 1
Dim csi As CShItem = lv1.SelectedItems(i).Tag
[CODE]...
When deleting multiple files a confirmation message box pops up for each file selected. I would like to have it come up once and ask 'Are you sure you want to send these 'x' files to the recycle bin?' where 'x' is the number of files selected.
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)

I'v got a problem with two treeviews. I'm populating a treeview from a Backgroundworker which isn't visible, after that I want to move or copy al the nodes in that Treeview to the Treeview on my form since you can't add nodes directly to a Treeview on your form from a backgroundworker. Does anyone know how I can transfer them? I tried things as .Copyto and .Addrange, but I couldn't get it working.

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 have a 3 layer treeview and is using the code below. I am getting it to do the following,
1) If parent is checked, check all child nodes.
2 If just one child node is unchecked, uncheck parent node.
3) If all child nodes are checked, check parent node.
Code below only works for 2 layers. Would appreciate if you can guide me how to make it three. There are much information on treeview but most of them seems irrelevant =/ Will be great if you can show me a good guide on treeview control.

I have the following code which checks for the value of the 'cc_supplier_status' column for each of the rows in my table. If the state is 0, I need a child node to be added to a node named 'Inactive Suppliers' in my tree view (tvw_Supplier) with it's text being the value of the 'cc_ supplier_ name' value for the same row.If the state is 1, a child node is to be added to a node named 'Active Suppliers'.If the state is 2, a child node is to be added to a node named 'Pending Suppliers'.The code I have now just filters out the status value for each row, and performs a select case on it. I need to know how I'd add a new child node to the parent nodes mentioned above.[code]
