I have a tree view in my project with a parent node and with theoretically speaking infinite child nodes.
Now I want to delete the last child node from the tree view when the user presses a certain button. I thought I could do this trick with this code:
Private Sub Bundo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Bundo.Click
Try
[Code]....
Is it possible and if so, how does one go about doing such a thing. I am loading a network directory in a treeview. Can the parent node be disabled, meaning it can't be selected, it's available for viewing only, but leave the child nodes selectable?

View 1 RepliesIn my Form I have the Tree View in which I want to Add the Node during the Run time.
For that I used a Context Menu Strip and on the Click of the Pop menu I added the new Node.
but my problem is my newly added is not editable by default
but instead I need to select the newly added node and after selecting the node I again need to click the Record to Edit it.
So is there any way that newly added node will be added Editable?

View 1 RepliesI want to select a node from my tree view, whatever I select is going to get a record from my database, I need a unique ID in each node so it will collect the correct document relating to the selected node.
How can I do this? the name of the node maybe used more than once? Each row in my database has an ID and Title, the title is the name I guess the ID being unique needs to be tied in somehow.

I tried creating an NDESELECT object to "remember" the node - then tried the old boolean first/loop trick - but it's not remembering that SELECTEDNODE. Seems that the NDE object is just a node object - maybe not "smart" enough to know where it got loaded??

View 1 RepliesI have a treeview with nodes being represented as checkbox.
All works fine i.e when a parent nod is checked, its child and sub child should be checked as well but it won't check only the first subchilds and i am not able to find the solution, i have debugged it many time, but still not able to figure the solution.
I tried finding the solution on the web, but didn't got the proper solution. Below is the code which i am using in my form.
Private Sub trvModule_AfterCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles trvModule.AfterCheck, trvReports.AfterCheck, trvMasterAccess.AfterCheck
[Code]....
I was wondering how I would go about placing a check in the checkboxes for each child node of a parent node in a TreeView control, if I was to check the parent node.
For example:
Parent 1Child 1
Child 2
Child 3
If I was to check "Parent 1" how would I be able to make that event place a checkbox beside all of the child nodes of "Parent 1"? (Child1, 2, and 3.)

I am working on Treeview control and Gridview Control VB.NET08. In the Treeview i have Parent and Child Nodes. Like: [Code] Comparing the Parent Node text and first two digits in the Column values. I want to add rows inbetween the gridview rows based on the parent and Child Nodes. If i expand the First Parent Node Called "31" then according to the Number of Child Nodes (for first parent node(31) there are 5 child nodes.) add rows in the gridview.
These New rows should be add under the 31-xxxx. If i expand the 32 Parent Node based on number of Child Nodes, add rows under the 32-xxxx. [Code] I am getting the rows in the end of the Gridrow not in the Specific row.
Everything is fine except the underlined code says-'Expression is of type 'System.Environment.SpecialFolder', which is not a collection type.'
All I want to do is add the node to the treeview. Let's say that I want "My Program" to be the node in the treeview, and THAT node is a folder inside my program files, which also has a folder inside of that which is called "Projects".[code]
how I can add a tree node with 2 lines of text, OR how to add a non-collapsable childnode to an existing child node. Basically my treeview consist of a list of groups, and inside each group is the contacts that belong to that group. Im trying to append a line of text to the existing contact when their status changes to busy, or not available.
example
// Current Contact List //
+ MyFriends
Timmy
Frank
Bob
What happens when I try to add the child node to the existing child node is it gives me the + sign so it can be collasped! I want the child node to be visible at all times. So it looks like this
// Contact List //
+ MyFriends
Timmy

my arr keeps coming in at 0. I have no idea why. I have tried messing around with different options but im coming up with nothing.
suppose i have a tree that have a root node. that root node have 3 child nodes. each child node have 3 child nodes and so on say up to level 4. if i number each node from the root node and numbering from left to right, the root node being number 1 and the left child of the root being number 2, the middle child of the root being number 3 and the right being number 3. on the third level the left child node of the left child node of the root being number 5 and so on. if i have numbers 1 up to 13 and want to put each number into a node numbered the same i.e number 1 gets into the root node, number 2 gets into the left child node of the root and so on. how would i achieve that.

View 1 RepliesI have a treeview which i populate dynamically using an XML Datasource. The leaf nodes in the TreeView attempt to open a URL in an iframe within the page.This all works fine, but i would like the iframe to be hidden until the point the leaf node is selected.what event is triggered when the nodes are clicked?? I tried the SelectedNodeChanged event but this doesnt seem to get triggered!
UPDATE - The TreeView code is shown Below
<asp:TreeView ID="TreeView1" runat="server" OnSelectedNodeChanged="TreeView1_SelectedNodeChanged" DataSourceID="XmlDataSource2" AutoGenerateDataBindings="False">
<DataBindings>

While fiddling with my code i noticed that when i remove the NavigateUrlField="URL" from my code the tree triggers the SelectedNodeChange event, But does not Trigger if NavigateUrlField="URL" is put back in.
