By clicking on Item1, item1b and 1c must be hidden or showed...
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

While i'm still trying to debug my treeview code, i guess now would be a great time to ask how to get the information that i click onto a listview.

View 3 RepliesI have a form to manage student. When I add, the data appear on ListView and TreeView at the same time and the same data. Everything works perfectly.
But one proble about Delete button. I choose the line from the ListView and Delete it. The ListView delete the item perfectly. But I don't know how to delete the item on ListView and automatically delete the item on the TreeView.
Note: When you insert the data to ListView and TreeView. When you fill the information into the textbox. Remember after that choose class on TreeView and Click BUTTON ADD.
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()

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.

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
how to change the Example 1 code to work with Example 2?

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.

When inheriting class or control e.g. ListView, TreeView, etc..., what is the best way to distinguish between built-in methods/property/events and mine?

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
