Basically, I have a view (can be converted into a store procedure) with two tables NODE and CONTACT. NODE is the parent table (NodeID) with the foreign key field in CONTACT (NodeID). The query works fine. I would like the treeview to look like this

I have a treeview from which I select a node, then click a button. That button adds the node to a treeview in another form. Now the node is there when I start up the form, but when I close and reopen it, its gone again. How can I keep it in the treeview?Also, how can I name the node, now I use this
Form2.Treeview1.Nodes(0).Nodes(0).Nodes.Add("5")
I'm begining to use the treeview control in vb 2008 and I use this line of code to create new nodes at runtime
Treeview1.Nodes.Add("New Node")
my problem is when I close the application and open it once again the nodes I created does not exist, how to rename nodes at runtime?
I have a requirement to create a multi level treeview in ASP.Net (with VB) but I am completely stuck on how to start this. Currently my treeview is a fixed 2 level approach but now I need to rewrite this to be more dynamic and support extra levels being added into our database tables.So this treeview needs to support as many levels as needed without having to rewrite any code each time we want to add new level, Ideally we will just insert the data at the database level.I think I have the database part designed correctly, I created 2 tables Menu and MenuItemsMenu has 2 columns ItemID and ChildIDMenuItems has 2 columns ItemID and Description Doing this query:
SELECT
menu.Item_ID,
menu.Child_ID ,

I have a requirement for a new application development where I must present some information to the user for selection via drag and drop. VB offers the TreeView control which would work nice, however the user does not like the Treeview control's presentation. The user wants a control that work similar to the Mac's Finder control while in column view.
Apple's Mac Finder Control works similar to window's treeview. Finder has a nifty view capability that my users would like in some new development that is being done. The finder supports a "column" view. Similar to the treeview, it starts out in a root list. The difference being, when a user makes a selection and clicks on a node, the node doesn't expand, the sub nodes appear on the pane to the right of the list. Clicking on a sub node, will cause the pane to split again and the items within that sub node appear
to the right again.
This will happen again and again with the left pane getting narrower as the user drives deeper into the sub nodes. That is what I am trying to replicate. Obviously, once the user reaches the base list of items, we have to support drag and drop capability. Does anyone know of a control for VB.NET that work similar to the Mac's Finder control?
I want to create a simple treeview from a database table. It is going to be recursive and I want for each item to show the description and in the background of each item hold a key value. Then when the user selects a node I can use that key value to select the data.

1. collapse and expand treeview when i click plus sign (+) on treeview, treeview didn't expand subfolder but when i click image, treeview expand it.

This is my code..
I am making a user control named MultiSelect, which consists of a textbox. In this textbox I put substring. I want the user control to show a treeview outside the MultiSelect boundaries where items matching the substring will be shown.
For me its no problem to make a treeview inside the MultiSelect boundaries but I need to save space on the original form where a MultiSelect control will appear, so I need to do it like the treeview will appear and after I choose items, it will disappear
I have a tier application based on this video url... So far the client application only has a reference to the Business Logic (not Data Access).If i needed to tie a control such as a TreeView to list certain data fields from my table then where and how should i do that? For example i could write a For each statement to iterate through the table which returns the item from a table or i could do it in the WCF service app but how does this tie in with a control such as TreeView especially when there are no references?

I have tried a few ways, mainly 'copying' the code from this recent codebank submission. However, I keep getting the obvious cross-thread call issue that I am adding nodes to the 'node' parameter, which is not allowed.
I am at a loss at how to do this otherwise. How can I update a Treeview like this if I have to recursively add nodes to the 'node' parameter, which is not 'available' in a separate thread?
I've created a treeview that is going to represent a 'table of contents' for a Word template I use frequently and I need to add checkboxes to each node of the tree view.
Here is some of my code so far:
tvwSIGtemplate.Nodes.Add tvwSIGtemplate.Nodes.Item(2), tvwNext, , "3. Statment of the Issue and Solution"
tvwSIGtemplate.Nodes.Add tvwSIGtemplate.Nodes.Item(3), tvwChild, , "3.1 Issue Details"
tvwSIGtemplate.Nodes.Add tvwSIGtemplate.Nodes.Item(4), tvwNext, , "3.2 Solution Details"
What to add to these lines to simply display a checkbox next each line?
I have a treeview control with check boxes. when I check the parent node, all the children check too. The problem is, I want the parent check box to automatically uncheck if one of the children is unchecked.
Private Sub TV_Communities_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles TV_Communities.Click
For i = 0 To TV_Communities.Nodes(0).Nodes.Count - 1
If Not TV_Communities.Nodes(0).Nodes.Item(i).Checked Then
TV_Communities.Nodes.Item(0).Parent.Checked =
False
End If
Next
End Sub

View 12 RepliesI have a TreeView control in VS 2010 that I need to be able to INSERT (not add) nodes to. I have stored a unique key in the TAG for each node and know how to find the value of the tag in the tree. However, I can't figure out how to INSERT a NEW node BEFORE or AFTER the node I have found with this tag.
For example, suppose I have the following tree . . .
Item 1
... Item 2
... Item 3
... Item 4
[Code].....
I need to be able to do this for any particlular level of the tree (not just the third level where Item 6 is located). Also, Item 6 could have CHILD NODES associated with it but I need to leave those child nodes assoicated with Item 6 and INSERT Item 6.1 below (or above) Item 6 at the same level as Item 6.

View 7 RepliesThen I progressed to using the tabcontrol and multiple tabpages to group associated data for manipulation.I'm thinking the treeview control could be used to create a slick options page, however with the previous methods all the controls were drawn in design time, making it easy to edit events/properties etc.., I can only think using a treeview control on a single form that controls would need to be added programmatically/dynamically.

View 2 RepliesI am using a treeview to display projects, tasks, time entries, and the people who are working on a project. I would like to allow the user to define a custom grouping (ie. Project->Task->Time Entries or Project->Date (of time entry)->Task->TimeEntry).The relevant groups would be Project, Task, Time Entry, and Person, with some metadata from them. I want to have some modular way to allow a user to specify how they would like to display the information. Does anyone know of a good method by which this can be done? I currently have hard-coded a display which looks like this:
Project
Task
Time Entry

after a week of trying to find a control that combines the Treeview/Listview, a so-called TreeListView, I gave up. The ones I found are either buggy or have too many features (making them heavy).The best way for my personal needs is probably to use an ownerdrawn Listview and doing the indentation (expanding/collapsing) myself.There are a few problems:
1) I can't get the Plus/Minus images to show properly. If I expand a 'node' and collapse it, then the Plus image doesn't show. If I expand two 'nodes', then the Minus image of the first expanded 'node' becomes a Plus image again.
2) Clicking the Plus and then Minus image too fast causes weird flashing behaviour of the 'node' expading/collapsing.
3) Somehow I need to be able to update the Listview in real-time. I know I can use ListView.RedrawItems to refresh a single row, but I need some kind of structure to know which 'nodes' have been expanded. When a 'node' gets expanded, then everything below gets a different index.
