Add Columns To TreeView Nodes?
Dec 13, 2009I'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.

Adding Columns And Modifying Columns In Access Database Using NET/SQL?

Original DataTable Object Has Columns Added When Variable Has Columns Added?
Oct 6, 2011I have a datatable property called prpParametersTable in a class called clsBatch. I have a procedure that sets a datatable variable called dtP equal to prpParametersTable at the beginning of the procedure. I then add three new columns to dtP.Here is my problem. When I add the three new columns to dtP my original table prpParametersTable also gets those columns added to it, why? I only want to add the three columns to dtP and not prpParametersTable. How can I do that?

C# - 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.

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"
