I have an xml file with following structure:
<table name="tblcats">
<row>
<Id>3680</Id>
<Industry>Associations</Industry>
[code]....
I want to create a treeview using this XML file. I have written following code
' Load a TreeView control from an XML file.
Private Sub LoadTreeViewFromXmlFile(ByVal file_name As String, ByVal trv As TreeView)
' Load the XML document.
[code]....
where as I want table as parent element like this
->table
->Associations
->Fortune 100
so that If i click table node, all tree collapses or expands.
How can i programmatically create a treeview consisting of several nodes and each node has several children.I want to read the nodes and children from a table and fill them accordingly, so how can i do this?
View 1 RepliesI've a treeview in my project form which look like this.
-Cover Page
-Video1
-Podcast1[code].....
The user will be able to upload their pages to the respective pages nodes and I am suppose to make it in such a way that after the user uploaded the cover page which is showing at the PictureBox1 which I've use to display the image, and when he uploads the second page image at the PictureBox1, the Cover page image that he uploaded earlier on will not be overwrite.
I was told to create class and use array to store the contain in the respective nodes but I do not have any idea how to do it.
I am creating an Add-In that I want to create classes and forms based on a database structure. I can't find any information anywhere on how to programatically add code to classes. I know I can write out the files and add them to a project, but that would limit what I can do in the future. I would like the possibility to update a function in the future which would be impossible writing out a file and loading the whole thing back in. It would destroy any modifications made to the class, and since this Add-In will only be creating a framework, there will usually be modifications.
I got this line from the macro recorder:DTE.ActiveDocument.Selection.text = strDACode
But I like to keep Option Strict on, and this is late bound according to the IDE. There seems to be very little help on the IDE and how to use it creating Add-Ins. If I overlooked something please point me there, but I can find nothing. I don't know if it can be done, but I was able to do it in an Add-In for VB6.I would also like to add controls to a form, so if anyone can point me somewhere where it explains
i have a treeview which has a bunch of parent and child nodes preset at design time, there is 1 parent node tho which is called developer, that i want to add child nodes to at runtime.When the form first loads im trying to have it check a text file and for each line in the text file add the text/string from that as a child node tot he 'developer' parent node.

How to add a child node to a specific node in treeview?
Say i have "Item1" in treeview already, How do i add "SubItem1" to "Item1" as it's child node?
I know its probably really simple, but i tried lots of stuff, i just cant get it working.
Is it possible to remove a node from the treeview identifying it by the node's tag? if so how?

I want to add key while adding node to the treeview but I don't see key property in the treenode. I am using following code
objAddSubFolders = New TreeNode
objAddSubFolders.Text = arrListDisplayFolders(intCountSubFolders)
objAddSubFolders.Name = arrListDisplayFolders(intCountSubFolders)
objParentNode.Nodes.Add(objAddSubFolders)
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.
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"
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.

The strange thing is that this issue only appears in IE, I have tested it in chrome and Firefox and both browsers display the text perfectly.
When I select a node this fixes the problem and all text displays as normal.

View 12 RepliesI have a TreeView.I am building the nodes within a For/Each loop.I then add icons to each node from an ImageList control.The icons load properly. However I am noticing that when I click onto the nodes, after the TreeView is built, the selected node defaults to another image. It seems to always default to the image which has the index of whatever is set in the Properties Windows for the Control for ImageIndex.So assume that the ImageIndex is set to 0 in the Properties Window.If I add ImageIndex 1 to the node at run time (See Below), ImageIndex 1 show up but once I click onto this node the icons switches to ImageIndex 0.[code]
