In the past I have created a hierarchicaldataset from a dataset but would like to stay within the entities framework if I can

Hi, i'm trying to use the treeview to display the text of a rtf (rich text file) file when an specific node if clicked.HomeOMGWOOTFor example, if i pick OMG, i want the text of lol.rtf to be displayed on a richtextbox. But somehow i just can't manage to get it... I know to import the text of a .txt file to a textbox, but using the treeview makes it more complicated.This is the code im using right now:
Private Sub TreeView1_NodeMouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseClick
Select Case e.Node.Index
Case 0
[code]....
Another thing is, that i can't import the *.rtf text into a richtextbox and i don't know why.

The treeview system I am using is by Andy Bonner from the following Link, as advised I have created a new post.[url]...
Andy you were asking what it is I am trying to do so I will try explain it a little better. The treeview system you have created allows me to import / edit and save XML files based on the treeview structure that I create. What I now want to do is use the same XML files to populate buttons on a form.
So for example if I have 10 buttons on a form then on load it will look at the xml file and change the text of the buttons to whatever the main level of the treeview is.[code]...

I am playing with a simple file browser using TreeView. Why would I get "Access to the path is denied" on My Pictures, My Music and My Videos? No problem with My Documents and countless other folders and sub-folders, just My Pictures, My Music and My Videos. Obviously I can access these folders fine in Windows Exlporer or from VB.NET using OpenFileDialog. I'm using Windows 7 64-bit BTW:

I'm thinking of using the treeview to organize my text file. My text file looks like:
0|app1|Z0
1|app2|A1
2|app3|B2
And, the list goes on. I think i should be able to organize this with split command. But I also i have checkboxs on my form. If for example the user unchecked the "app1" then i want only "app1" to be unchecked from the listview, and removed from the text file. The question is how could i remove that specific value from the text file.

I have a DataAccessLayer that returns a datatable. The business layer calling it also returns a type datatable.In my form, I call the business layer as a datasource of my gridview and then I binded it.
This codes are working in C# but I have problems when I converted it to VB.NET. During databind it displays the error: Data source is an invalid type. It must be either an IListSource, IEnumerable, or IDataSource.
Can i not bind a datatable in my gridview in vb.net? What do you think is the problem?

I have a DataGridView that is inside a TabControl. After I bind the DataGridView with data, the first row is selected. How do I prevent this from happening. I tried DataGridView.ClearSelection and DataGridView.Rows(0).Selected = false. Neither of these options work. I think it has something to do with the tab control not being completely drawn before I call the methods. If I run this code from a button it works.

This is a follow-up questions to the following post: [URL]
Below (Example 2) is working code for populating a treeview with directories only down to 1 level. Note just directores are added- No files. I want to add a Listview control beside my treeview and have the Listview populated with the "files" from the selected node in the treeview. This would fire off the NodeMouseClick event of the treeView. I have used Example 1 (NodeMouseClick) before with other code that I have. However, I cannot get the code to work with the Example 2 code below
how to change the Example 1 code to work with Example 2?
Example 1
'************************************************
Private Sub treeView1_NodeMouseClick(ByVal sender As Object, _
ByVal e As TreeNodeMouseClickEventArgs) _

My dropdownlist is set to databine like this...
dt = dal.FillDataTable(SqlConnectionString, "SELECT SQL Query Statement")
dropdownlist1.datasource = dt
dropdownlist1.datatextfield = dt.columns.item(0).tostring
dropdownlist1.databind()
This is turn populates my dropdownlist, when a user selects a value, it is then populated to the remaining textboxes on the remaining forms with a session call...
dropdownlist2.add(ctype(session.item("valOne"), String))
Through this session it populates the one value, is it possible to display the selected value but also include all other dropdownlist items in case they want to change thier selection?
