Is it possible to have a script which will enable me to right click on a node in my treeview which will bring up a menu similar to when you right click on this page but with my own options on it?
View 4 RepliesWhy 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 Repliesfor 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 want to add a node just above all removable drives from the thread I asked about in before. I decided that I don't want to have "C:" as a node, instead I just want my program to be the node. I've worked with this before but i can't figure it out without messing up what I already have.
View 6 RepliesAll my TreeView nodes have a unique ID for their Node Depth.
I want to set Checked=True on the TreeView Node which matches a certain value.
Currently I'm doing the following:Dim value As Integer = 57
For Each n As TreeNode In tvForces.Nodes
If n.Value = value Then n.Checked = True
Next
Is there a better way of finding the Node which I want to set as Checked=True rather than looping through each node?
I'm looking for something like:Dim value As Integer = 57
n.FindNodesByValue(value)(0).Checked = True
Is there anything like this that I can use?
I have a TreeView in my form that I populate manually from a list of items in a database. The descriptions of the TreeView items causes a horizontal scrollbar to be displayed. That is fine except that it seems that this scrollbar hides the item at the bottom of the TreeView. If I expand a tree node the bottom item that was previously hidden will be displayed.

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 have a treeview in my program that lists all the folders and files in my TV Video collection. The tree lists as follows:
TV Series
|___SeriesName
|___SeasonNumber
|___EpisodeName
The problem I am having is that the SeasonNumber node does not sort 'properly' as I would like it.
It sorts like:
Season1
Season10
Season2 etc.
Instead of:
Season1
Season2...
Season9
Season10 etc.
I have tried this:
Private Sub scanFilesList()
Dim sfilenames() As String = System.IO.Directory.GetFiles(folderPath)
For Each strFileName As String In sfilenames
strFileName = GetFileName(strFileName)
tvVideoList.Nodes(n).Nodes.Add(vGroup, strFileName, 2, 2)
[Code] .....
As I understand it, this is supposed to sort ascending but it doesn't seem to change anything. I really only need to get the grandchild node sorted 'properly'.

View 2 RepliesI 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.

View 2 RepliesI 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"
I am now trying to get grandchild nodes in my treeview, i have got everything working, BUT instead of the nodes being put 'IN' the child node they are being put 'BELOW' it.
