Populating A TreeView From A TreeView Instance
Sep 13, 2010I have a class, let's call MyClass. In this class, I have a TreeView property let's call myTreeView..In my code, I populate the Nodes of this TreeView so I can use it later on.Then, when it's time to actualy use it, I haven't been able to take all the nodes from myClass and put them in a Tree View Control on my form.[code]The weird thing is that when debugging, the TreeView in MyClass is well populated with the proper values and in the loop, newNode isn't empty, there's actually something but for some reason it's not showing anything.

View 12 RepliesC# - TreeView TreeNodeCollection Key?
Dec 8, 2010The TreeView uses in its underlying implementation the TreeNodeCollection. The TreeNodeCollection in almost every overload of the add method asks for a key.It also implements indexOfKey and ContainsKey yet there appears to be no way to determine the key of a node from the node itself or from any of the events you would typically use such as TreeView_AfterSelect().
Am I correct or is there in fact someway to retrieve the key from a node or event which I have overlooked? And assuming I am correct. Why on earth was it implemented in such a way? The only thing I could think of was that perhaps TreeNodeCollection.Key is deprecated? But I see no mention of this...
PS: I am aware of the TreeNode.Tag property and how it can be used to the same effect.

C# Conversion With The TreeView In WPF?

Database - WPF Treeview In .net?
Nov 15, 2011I have been looking for a some working code for the last couple of days to set up a treeview in my WPF app to display some database data. I use VB as i am much more confident in it - which drastically limited the code examples out there. More examples i found used manually entered data to populate each node versus a database which was little help. I finally found some code which bound the each node to a query and related the query via a DataRelation. Great this should work perfect!
The example used the Northwind database so I changed it to my database and plugged in the queries. To my shock the treeview populated fine except.... all the data is invisible.
Here is the code:
Imports MySql.Data.MySqlClient
Imports System.Data
Imports System.ComponentModel
[code]....
and here what i end up with the data seems to be there but you can't see it.PS there may be some confusion as to the objects. I went back tried to keep as close to the original code as possible when i discovered the problem only replacing the queries with my own - the original code used "Categories" and "Products" where as I "use Distributors" and "Titles"
