I have an explorer skeleton to which I have added roots and nodes in the TreeView. How do I change the contents of the ListView depending on what in the TreeView is selected? In the Code below I have three roots in my TreeView and some default items in the ListView

I am working with buttons I have A treeview that when you click on a node it changes the text in textboxes and I need it to change the command the button does. So when a user clicks a node it changes text in 3 text boxes and changes the download link for the button. As you can see from the code all works fine but I need to use a button to download stuff and I dont know how the download code is
My.Computer.Network.DownloadFile _
("[URL]", _
cookiepack)
MsgBox("done")
That's what I need the button to do
Private Sub TreeView1_NodeMouseClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseClick
Dim filePath As String
filePath = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)

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.

after a week of trying to find a control that combines the Treeview/Listview, a so-called TreeListView, I gave up. The ones I found are either buggy or have too many features (making them heavy).The best way for my personal needs is probably to use an ownerdrawn Listview and doing the indentation (expanding/collapsing) myself.There are a few problems:
1) I can't get the Plus/Minus images to show properly. If I expand a 'node' and collapse it, then the Plus image doesn't show. If I expand two 'nodes', then the Minus image of the first expanded 'node' becomes a Plus image again.
2) Clicking the Plus and then Minus image too fast causes weird flashing behaviour of the 'node' expading/collapsing.
3) Somehow I need to be able to update the Listview in real-time. I know I can use ListView.RedrawItems to refresh a single row, but I need some kind of structure to know which 'nodes' have been expanded. When a 'node' gets expanded, then everything below gets a different index.
for example...when i click the folder in the TreeView, the ListView will display all the items in the folder....but how to write the codingcoding for TreeView
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I have a small problem with a list view and tree view. When i click on the first child node a form opens. Because my listview is populated dynamically when i click on treeview, i want the listview itemes to inherit the function of the treeview. For example, instead of cliking the treenode in the tree view to open a form i will click the list view item and the form opens.

Below (Example 2) is working code for populating a treeview with directories only down to 1 level. Note just directores are added- No files. I want to add a Listview control beside my treeview and have the Listview populated with the "files" from the selected node in the treeview. This would fire off the NodeMouseClick event of the treeView. I have used Example 1 (NodeMouseClick) before with other code that I have. However, I cannot get the code to work with the Example 2 code below

View 2 RepliesIs it possible to programatically change the color of entire listview columns (vertical)? I know it's possible to change the color of entire rows (horizontal): ListView1.Items(priceRow).BackColor = Color.FromArgb(87, 68, 34) Changing the properties (forecolor, backcolor) in the listview collection editor did nothing.
View 2 RepliesI 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.

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.
