Title: Visual Basic .net - Tree View
Post by: nila on February 02, 2004, 05:09:44 pm

Hey ;)
Just installed VB .net and tryin to get to grips with it.
The tree view is the most basic thing I'm having problems with?

I can work out how to add root level items:
treeview.nodes.add("blah")

and child nodes to that root level item:
treeview.nodes(0/1/2/etc).nodes.add("blah2")


But I cant for the life of me work out how to add nodes to that child??
or to it's childrens children etc??


Also, with VB6 there was the drop down menu to chose events 'MouseOver', 'MouseDown' etc.

How are these chosen in .net or is it all just hand coded?

Thanks for any helps and tips to get me started ;)

TreeView.Nodes.Add returns a TreeNode object which you can manipulate from there.

For example:

Code: [Select]

Dim i as Integer
Dim tv as new TreeView
Dim currentNode as TreeNode = tv.Nodes.Add("Root")
For i = 1 to 5
 currentNode = currentNode.Nodes.Add(i)
Next i
Will create a new TreeView object (which you can place and size wherever) and then add one root node called "Root" which has a sub-tree five levels deep.

As for the object events, There should be two drop-down comboboxes above the code view. The left one selects the object and the right one selects the event.
