View 1 Repliesi have a treeview say TV1 and another Treeview Say TV2.. Now TV1 Contains all nodes for user rights. and i want to add to tv2 only selected nodes.Like TV1 is
Node 1
....Child of Node 1 (Level 2)
.........Child of Child of Node 1 (Level 3)
what i want is that when i select Level3 Node it should chek TV2 for the parent of this node. if parent exist it should add the node under the same parent. if parent does not exist it should check for Level 1 Node and if it exist it should add Level 2 Node and then Level 3 Node. Otherwise it should add Level 1 , Level 2 and then Level 3 Nodes in order.
I 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.

I am creating a project in VB.NET in which one of the reports require that the name of employees should be displayed as column names and whatever work they have done for a stated period should appear in rows below that particular column.Now as it is clear, the columns will have to be added at runtime. Am using an ODBC Data source to populate the grid. Also since a loop will have to be done to find out the work done by employees individually, so the number of rows under one column might be less or more than the rows in the next column.Is there a way to create an empty data table and then update its contents based on columns and not add data based on addition of new rows.

what WPF based apps are?Is it an application that runs under Silverlight? If so, how?I know; Windows Forms based apps,console apps,DLL _ Class Library Projectsand I've had an introduction to ASP.Net.What I mostly want to know is, if WPF apps are for Silverlight then do they also run in a server based fashion like anASP.NET website would when you create ASP.Net webpages?Is it a way of creating what looks like a FORMS BASED application but it runs in a browser instead or what?Please enlighten me a bit further as I have no idea what WPF is all about.
If it's 0-based, how can we add a placeholder to make it 1-based?

View 12 RepliesThe 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.

I'm working with a TreeView in a VB.NET to C# conversion project. I have this VB.NET WinForms code
Dim Arguments1 As String = path & "" & fs & " ls " & TreeView1.Nodes(ccc).Name

string args = path + "\" + fs + " ls" + ...
I would assume it would be
.Items[ccc]
but there is not name attribute in that
I 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"
