Use A Treeview Control To Display Related Data As Folders(Level0), Projects(Level1), Drawings(Level2)?
Oct 14, 2009
I would like to use a treeview control to display related data as Folders(Level0), Projects(Level1), Drawings(Level2). So far I don't have a problem reading data from a database, creating classes to hold the data and displaying the tree from the class data. I have created (3) contect menu strips, one for each level of the tree to perform various tasks. Each menu has an ADD option to either add a folder, add a project or add a drawing.My problem is as follows...After I add the node, in the correct location, I would like to have it set in the BeginEdit mode.
Dim oNode As New TreeNode
oNode = TreeView1.SelectedNode.Nodes.Add(sNextID, "New Project")
oNode.ImageIndex = 1
TreeView1.Refresh()
[code]....
After this code runs, the node.Text changes back to "New Project". As you can see, I added a few debug.print statements to try to see what is going on. It really blew my mind to see that the entire tree printed in the immediate window.I have already created a work around for this, but is isn't really the way I'd like to see the program run.

I have seen lots of examples with a treeview to list folders then display the folders context in a listview.
But what id like is a checked treeview, that not only displays the folder list, but the actually folder contents as well.

I created Dataentry forms. In the form there are so many controls like DropDowns and textboxes. I am using Access database. Now I enterd the few records into the controls, and these records are saved into the Database. But now if i enter the any data which i recently saved in the database to the textbox or any other control then the remaining controls should be display the related data.
For example i have 4 controls in my form one is dropdown and 3 are textboxes. If i select the data in the dropdown then the remaining 3 textboxes shows the related data. How can i dispaly the corresponding data to the other controls?

I have used the TreeView and populated the list using the following code:
m_strStation = cboStation.SelectedItem
For Each strDir As IO.DirectoryInfo In New IO.DirectoryInfo(m_strPath & m_strStation).GetDirectories()
trvFolders.Nodes.Add(strDir.Name)
Next
The TreeView populates and every folder is visible, however the folder names consist of:Place #. Name the problem I am having is that the number range is 1 - 16 and the order in which the folders are being displayed is 1, 10, 11, ..., 15, 16, 2, 3, ..., 8, 9 I am looking for the folders to be listed in true numerical order e.g. 1, 2, 3, ..., 14, 15, 16

I'd like to use a TreeView control to display database data in a windows form with VB2008. All the information what I found is related to a website design, but I'm working on a database program (sql2005), where I'd like the user to see the structure what he/she make up with a TreeView like control. Just something like that when you explore your hard disk. How can I do that?

This is driving me crazzyy. I need a simple way to display all of the folders and subfolders of an FTP directory in a treeview, similar to the layout of Windows Explorer. Here's the code I have:

The code is total crap... causes my app to hang. Pretty sure infinite recursion is the cause.

I have a treeview, it lists all folders and subfolders and files within each folder. Now, I want to display each file / folders associated icon. I am using the SHGetFileInfo API, it works sort of, what I mean by sort of is, that my treeview doesn't update after each folder / file. Sometimes it keeps giving me the Recycle Bin's icon at different folders.

This is somewhat of a multi part question, let me start off by explaining what I'm trying to do. I have an organized folder system with data files in them. Each folder has a set structure to their naming, and can contain sub folders and files. It will be a jagged directory system. I'm trying to import their structure into a TreeView. I have the workings of a recursive system that adds all files and folders into a ViewTree, however they aren't organized by parent/child.
So I get this...
-C:Temp
-C:TempData
-C:Tempfile1.txt
-C:Tempfile2.txt
-C:TempDatafile3.txt
-C:TempDatafile4.txt
etc........
How would I go about parsing the directory paths, and include them into a parent/child relationship... looking like this
+Temp
--file1.txt
--file2.txt
-+Data
---file3.txt
---file4.txt
Also I when the line item is selected, I need to know which file is selected so I can use it's full path to call up data (using an API) based upon the it's full root path.

I have a datagridview bound to a bindingsource. Two of the columns contain values that link to the primary keys in other tables. Instead of displaying the primary key values, I would like to display the name of the item associated with the primary key. In other words, the primary key value may be 3 but I want to display "Furnace 5" in the datagridview instead of 3 (which it is now displaying).

I have a custom contro which inherits directly from Treeview. Is there any way to handle some event related to when the TreeView Scrollbar appears (it does this when the height of the stack of visible nodes exceeds the height of the control) or "disappears"?
I realize if could set up a function which checks the ItemHeight * Nodes.Count, and compares this to the control height. However, this seems clumsy. I have been exploring the object browser (and anylized TreeView with Reflector) and have not found what I am looking for. If there is a way to access the ScrollBar Property at ALL within TreeView, I have not found it.

I'm loading a folder (path), which contains folders and files, in a treeview according the combobox-text.
When I load the app. the combobox is filled with the paths. I'm using the SelectedIndexChanged to load the treeview. Everything works.
The issue is that it also starts to load the paths the treeview also gets loaded (slow), but it should only load when I select an item in the combobox.
I tried comboboxselectedtextchanged etc, but without any luck. Besides that loading the files and folders is slow.

I have two data tables. the second related to the first. Using a datagridview for the first table I am able to enter and save data ok. if I run the code twice in a row the data is still there. When I edit the data in the related table in it's own datagirdview the data is there and displays correctly, but on running the code a second time the related data is lost. In both cellendedit events I am using
Me.table.Update(Me.FigsDataSet.table)
