This is my code..
I am trying to sort a treeview, base nodes, which is the first base set you see before you click any + sign's I am trying to sort by alphabetical order, but, for the nodes inside each + view of the tree's I want to sort by number order, the number is currently set to the tag as text version of the number. Anyways, for the nodes in the + view's I need it to be able to skip over numbers if not every number in sequential order is there, so if number 4 is missing for example, still sort 1,2,3,5,6. My full code is pretty big but just retrieving items to display is random & I just add items as they come in, now they don't come fast or even when your not expecting new things to appear so it should not matter how it works really as it wont be updating as they are using the treeview.

View 7 RepliesI know that I can use treeview.nodes.find() but that will find the exact text so how would I search a treeview to find like items?
I have come close but this only searches the parents, never the children. Would I have to do a double search, start at parent and then get all nodes in parent?[code]...
I have this code..
If Form1.ListBox1.Items.Count = 0 Then
Else
Dim classSS3 As New StringSift3
Dim ReturnVal As Single
[code]....
What im trying to do is the returnval works its a compare percentage, dont worry about that. lb1 is the index of listbox1.selecteditem which is the first item, im trying to make it check the childnode for each root node in the treeview.but i get an error on.Form1.TreeView1.Nodes(Form1.lb1).Nodes(classItem).checked = True saying..Object variable or With block variable not set.
I need to know how it would be possible to arrange items in a context menu the same as the node in a treeview is arranged with the same text and everything.
View 2 RepliesUsing Webbrowser, I've managed to automate PDF downloads for several of the websites used by our company. I'm still a beginner at this process.Many of our PDF downloads, however, are from a Wells Fargo service called Wholesale Lockbox Image. The problem is that this Wells Fargo site expects the user to select items from a treeview as part of his query criteria. I don't know how to make Webbrowser select these treeview nodes programmatically.
Although I don't know anything about Java, the treeview is definitely a Java control. I know this for several reasons.(1) The instructions on the website specifically state that the the treeview won't draw until Java is installed.
(2) A standard Java splashcreen appears in the little treeview pane until the treeview actually begins to draw. The HTML code has an <OBJECT> tag which includes this attribute: ARCHIVE = "JWLTreeView2.jar"
Using Microsoft's mshtml library, I've tried looping through the elements on the page but can't find anything corresponding to the nodes in the treeview. I've also tried applying EnumChildWindows to the IE window, but here too I found nothing specific to the nodes. When I hover Spy++ over the treeview pane, it only identifies the pane as a whole, not the individual nodes.Furthermore, even when I select the nodes using my mouse, I don't seem to detect any corresponding alteration of the Webbrowser's HTML document (unless I overlooked it somehow).Does anyone have any suggestions on how to make Webbrowser select the treeview nodes programmatically?Oddly, I noticed that if the user saves the webbpage to his harddrive and then loads it into his browser from there, he can still see the treeview and select items (even without logging in to Wells Fargo), although if I bring the page home, the treeview is gone. I guess this means that IE is storing/caching the java file somewhere on the company machine, although I don't know if this fact would help solve my problem...
How do I display Items that are Checked from a treeView in a listBox using VB?

treeMeshList.Nodes(Position).Text = "Mesh #" + Position.ToString
Position += 1

I'm working with an Treeview and i'm new at it and i have 2 questions.
1. How can i save the treeview items, to settings (my.settings.history)
2. How can i save the treeview items as an TXT or XML file or another exception.
I have the following linq statement to go through a dropdown menu's sub items and get what items are checked: vb Dim UnselectedItems = From xItem As ToolStripMenuItem In tsiSelectObjects.DropDownItems Where TypeOf xItem Is ToolStripMenuItem AndAlso CType(xItem, ToolStripMenuItem).Checked = False
I get this error tho: Unable to cast object of type 'System.Windows.Forms.ToolStripSeparator' to type 'System.Windows.Forms.ToolStripMenuItem'. As you can probably guess i have ToolStripMenuItems and separators in there
However the AndAlso should short circuit in the case where the item is not a ToolStripMenuItem and it doesn't seem to be doing so (as TypeOf xItem Is ToolStripMenuItem=false in this case)?
i have a listview box full of items, image below:
when i click a button i would like a msgbox to pop up displaying how many are alive.
How would i do this ?
Also how would i remove all items that status is "Dead"
I know how to do what is in the subject already, but I want to do it a different way than what is stated in the subject. What I want to do is be able to create multiple items with different names and then load the names into a listbox. When I select the item in the listbox with the name, such as Item1, it will put the text from the control named Item1 into a textbox.
I am clueless as to how I could accomplish this. What I am doing is adding Items to a menustrip's dropdown Item, then adding items to the dropdown items. So I would have the item collection such as:
One
Two
Three
So I could choose the item in the listbox with the text "Three" and I could load several properties of the item Three. Such as Three.text, Three.Tag, and Three.Name. And I could also edit these. And then when Three is chosen in the listbox, I could add sub items to it.
So it would look like this in my perspective(Although the code would not work)

How can I delselect in a treeview and then cause an event to trigger when nothing is selected.
I can deselect when I left click any of the white space adjacent to any branches but not below them if that makes sense, is there any way for it to work when you are not adjacent to any nodes? I am using this code to deselect.

trvProjects.SelectedNode = Nothing
End Sub
I then want to be able to add a node at the parent level if nothing in the view is selected using my right click menu and I am using the code below to check if any nodes are selected when I right click

The General TreeView Structure, with the level indicated in the left.[code...]
Leaving the 0 and 1 levels, the other levels has to be treated as above. How to achieve this?
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 form with a treeview control (trvControl) which is created at design time. I have a sub which creates a temporary treeview (trvTemp) and adds a bunch of nodes to it. It then uses treeview.nodes.copyto and treeview.nodes.addrange to copy these nodes to the control on my form:
[Code]...
It all seems to be working except for one thing - nothing appears in trvControl.
I've run through the code and the node collection is definitely getting copied (I paused in another sub and checked trvControl.nodes and it was correct) but trvControl is still empty on my form.
Incidentally, the reason I am doing this is that I want to use a background worker to populate the nodes but don't want my app locking up for large amounts of time while I access the treenode through an invoke so I thought if I generate the node collection first and just use the invoke to load it into the array it would work better.

Table parent looks like this: pID as integer (pk), parentName as varchar
Table child looks like this: cID as integer (pk), parentID as integer, childName as varchar
This is my code now, fetching the parentnodes..

I am trying to dynamically build a TreeView. I want to be able to expand a top level node & have any child nodes be added on the fly. The problem I'm running into is that I can't get the "+" symbol to appear if there are no subnodes to begin with. I could probably add a "dummy" subnode, then when the parent node is expanded I could delete the dummy node & add my real nodes, but that sounds cheesy.
