TreeView properties treeNodeSrc - treeNodeTypeSrc

[ippo]

Hi all,
I have a silly problem with treeview. I'm using .NET 2.0. I need to
set the two properties treeNodeSrc - treeNodeTypeSrc at run time using
C#, but in the treeViews that I define, these two properties don't
exist!!!
Do I need to import something more to use all the properties of the
treeview? Right now, I 've just installed .NET 2005

Thank you all

How exactly do you know you need to set two properties
that don't exist?

Use the .Tag property of the node to store a custom
class in. Whenever you grab a node, get the custom
class back out of the .Tag

MyCustomClass blah = (MyCustomClass)node.Tag;

There are a lot of example, even in MSDN environment, using that two
properties to populate a treview. My problem is just that, in my .NET
installation, I cannot see those properties. It seems they are not
part of treeview objects I define, so I was asking if there was
something to include to use all treeview webcontrols features

Thank you

Since you are using a treeview I thought I would maybe you could help
me. I am new to C# and using the treeview in Windows forms. I can
connect to the DB (SQL 2005), create the dataadapter, populate a data
set. The problem is how to use the dataset to populate a treeview.

I have not found a Windows Forms C# example that can handle an
unspecified level of node nesting and Parent = Child. See child rows
15.

I would really appreciate the help.

Thank you.

I have a SQL Server 2005 table containing this data shown below.


Child...Parent...Depth.....Hierarchy
1.........NULL.....0.........01
2..........1.......1..........01.02
