Forms :: Select TreeView Node By ListView Selected Item?
Mar 23, 2010
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.

1. I need to be able to store the STR MG INT and SPD somewhere when they create an item and make sure it is assigned to that item, and since I allow them to create unlimited item, I need this way to be dynamic (as in create variables as needed).
2. I need to find some way to make sure the user has selected an item name in the treeview (not type or main node).For example, they need to click Hockey Mask and then click the equip item button for it to work?

I 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?

I have this code to select first node of TreeView. But when page loads the by default root node is other than first, I want to set the selected node as top most by default. Here is my code in page load but it's not working:
Dim nodes As TreeNodeCollection = TreeView1.Nodes
If nodes.Count > 0 Then
' Select the root node
TreeView1.SelectedNode = nodes(0)
End If
This gives the blue underline error on this line:TreeView1.SelectedNode = nodes(0)
The error is: "Selected Node Property is read Only"

for some reason I have to click a node in a treeview twice for it to register as selected. I've checked with treenode.isselected() and treeview.selectednode() and with both two clicks is required to show the selected node (1 click continues showing the previously selected node as selected) while the visual highlight/selection works perfectly with 1 click. Any suggestions on what may be wrong/how it could be fixed? (The node selection code is in the nodeclick event)

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.

I have a treeview control where I am dynamically selecting a node depending on user interaction. when a node is selected I want to be able to have the scrollbar go to the location of that selected node in the tree. The scrollbar is simply made by overflow:auto in the div tag where the treeview is located. Can someone give me some detailed code to accomplish this?

I 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

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.

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'm using the following sub routines to allow the user to move treeview nodes up/down:
Public Sub MoveNodeUp(ByVal Nod As TreeNode)
Try
If Not (Nod.PrevNode Is Nothing) Then
Nod.Parent.Nodes.Insert(Nod.Index - 1, CType(Nod.Clone, TreeNode))
Nod.Remove()
[Code]...
Is there a simple way to keep the moved node selected after the move?

I'm developing a windows application. I have a form in which there is a list box and a treeview control. My purpose is to fill treeview according to list item clicks. This is done using a pair of subroutines called ReloadPermissions and FillMenuItem:
Private Sub ReloadPermissions()
Dim p As New Permissions
Dim i As Integer
Dim it As TreeNode
Dim el As New List(Of String)
[Code]...
There are only two subroutines in which nodes are added to treeview control, and they are subroutines above. The problem is that whenever list item is clicked, node count displayed in treeview is increased!!! I checked number of nodes before and after call to tvPermissions.Nodes.Clear() using MsgBox. Results show that number of nodes isn't increased (1 before call, 0 after call, again 1 after ReloadPermissions() is called), but what is displayed doesn't show such a behavior! Refreshing window by putting it under other windows or call to tvPermissions.Refresh() has no effect.

Ok, so I have a listview on one form, and when a button is pressed it opens up a new form with the contents of the selected listview item and it's subitems in a series of textboxes. The user can then change the data in the textboxes and either press save to make the changes or cancel to close the window. What command would I use to change the selected listview item and subitems to whatever is in the boxes?
this is the code that populates the boxes:
Private Sub Form_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim appeditcontents As String = main.passlist.SelectedItems(0).ToString
[Code]....
