I 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 have a webbrowser control & a treeview control...once I load a website I create a HTML DOM tree representation of the website using the code below...What I want to do now, is the following:mouse over any HTML element, which will then select the corresponding tree node on the HTML DOM Tree select any tree node and have the corresponding HTML element highlight, with a red border around it?

I'm trying to programmatically select the first node loaded into a treeview.
There are 4 main branches - that each node is added to
'If ndeSelect Is Nothing Then ndeSelect = nde
Select Case cdr(1).ToString
Case "Translation"

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??
I have a list of my menu strip in a table with columns

I have a TreeView populated with some nodes, and some of those nodes have children. Is it possible that when the node, or child is selected that the entire node including the children be selected? I still want to deal only with the value of the root node, but for the UI I want the root + children to be selected.
View 5 RepliesI 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:

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 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">

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.
In 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

So is there any way that newly added node will be added Editable?

View 1 RepliesI am using Microsoft Visual Basic 2010 Express, and the language i am using is VB.NET
I would like to know how i can edit or view the contents of a node on a treeview in a sample project. I would like to view the contents of the node, and if it is possible I would like to know how.
I'm Trying to select node on treeview with:
Try
Dim nodes As TreeNode() = TreeView1.Nodes.Find("Test", True)
Dim node As TreeNode
For Each node In nodes
TreeView1.Focus()
TreeView1.SelectedNode = node
Next
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
As you can see I'm trying to select the node "test" which is also sub-node. But I get no error nor a selected node.
Why I right click on a node in my treeview the focus moves to this node and then immediately back to the previously selected node. Is there some way that I can allow the right click to select the node?
View 2 RepliesI have been working with VB 6.0 for years. I am converting an app that uses treeviews to VB.Net 2008. The way it use to work the tree grid started with a list of the drives on the system. Left click drilled down in the selected drive or directory. Right click would perform an action with the selected drive or directory. In VB.Net it appears you can only select with left click using the AFTERSELECT event. Is there a way to select a node with right click?
View 1 RepliesI would like to select a default node in a treeview(dirDB). That comes from a default drive selected in a combobox(drvDB) that selects files and puts them in a listbox(filDB) i haven't added anything to do that yet. at the moment i have this code:
If optMData.Checked Then
drvDB.SelectedValue() = "M:"
dirDB.SelectedNode.Text = Microsoft.VisualBasic.Left(CStr(drvDB.SelectedItem), 2) & "ase_wdata"
End If
I bet there is a function or a selectNode If kindof thing? i am totally looking over that can choose these. vb seems very good at putting things right infront of me and i just completely miss them..
I want to add nodes that behave in a similar fashion as when you add new folders in windows explorer. i.e. right click > new folder > then the new folder is added and highlighted as New Folder so that as soon as the user types they are overwriting the folder name.
I can add a new node as a child node of the node I have selected and label it "New Node" but I can't figure out how to select the new node and have it highlighted so that when the user types, they are overwriting the "New Node" text.
I have tried this but it doesn't work.
Private Sub AddProjectToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AddProjectToolStripMenuItem.Click
Me.trvProjects.SelectedNode.Nodes.Add("New Node")
Me.trvProjects.SelectedNode = trvProjects.Nodes("New Node")
Me.trvProjects.Focus()
End Sub
im trying to make it so that if a tree thing is clicked it will change the photo in a picture box. i already have it done but its a long code and i need almost 80 photos. in order to do that i will have to repeate this code 80 times
If e.Node.Text = "Blue tiger striped G36E" Then PictureBox1.Image = My.Resources.tigerg36e End If its on a key down event for the tree view, how can i get it so that i only need 1 line of code like
PictureBox1.Image = My.Resources + e.Node.Text so that if "Blue tiger striped G36E" is selected it will display a picture called "Blue tiger striped G36E" also if "Map" is selected it will display the photo that is called "map"
I'm using the following sub routines to allow the user to move treeview nodes up/down:

If Not (Nod.PrevNode Is Nothing) Then
Nod.Parent.Nodes.Insert(Nod.Index - 1, CType(Nod.Clone, TreeNode))
Nod.Remove()

Is there a simple way to keep the moved node selected after the move?
I have been playing with, and researching, this all day and can't figure it out. I have a Windows Explorer style form with a TreeView and a ListView. I've populated the TreeView with directories and when a node is selected, the ListView fills with the contents of the directory associated with that node. No problem there, but I want to be able to select a directory in the ListView and automatically select the associated node in the TreeView, just like it works in Windows Explorer. All the information I've found online tells me how to populate the ListView from the TreeView, but I haven't found any good examples of how to populate the TreeView from the ListView.

I can't work out how to add nodes to a treeview as a child of a particular identified node.
The treeview.nodes.add function has seven overloaded definitions each of which seem to add it as a child of the root node. I can't find a way to specify the parent.
I've found this article which gives an example
TreeView1.Nodes.Add , , "root", "Root Item"
TreeView1.Nodes.Add "root", tvwChild, "child1_root", "Child1 of Root"
TreeView1.Nodes.Add "root", tvwChild, "child2_root", "Child2 of Root"
TreeView1.Nodes.Add "child1_root", tvwChild, "child1_child1", "Child1 of
Child1"
I've seen several similar articles with the same format. However this doesn't work. I get compilation errors. It doesn't match any of the function definitions, and tvwChild is not recognised as a constant.
I've used programs before which have a treeview type panel which has a text box... what is this and how can I do it?
