View 1 Repliesi have a treeview say TV1 and another Treeview Say TV2.. Now TV1 Contains all nodes for user rights. and i want to add to tv2 only selected nodes.Like TV1 is
Node 1
....Child of Node 1 (Level 2)
.........Child of Child of Node 1 (Level 3)
what i want is that when i select Level3 Node it should chek TV2 for the parent of this node. if parent exist it should add the node under the same parent. if parent does not exist it should check for Level 1 Node and if it exist it should add Level 2 Node and then Level 3 Node. Otherwise it should add Level 1 , Level 2 and then Level 3 Nodes in order.
I have a class, let's call MyClass. In this class, I have a TreeView property let's call myTreeView..In my code, I populate the Nodes of this TreeView so I can use it later on.Then, when it's time to actualy use it, I haven't been able to take all the nodes from myClass and put them in a Tree View Control on my form.[code]The weird thing is that when debugging, the TreeView in MyClass is well populated with the proper values and in the loop, newNode isn't empty, there's actually something but for some reason it's not showing anything.

How can i add Columns to Treeview so that first column should be as tree and rest are like listview or Listbox.
View 12 RepliesThe TreeView uses in its underlying implementation the TreeNodeCollection. The TreeNodeCollection in almost every overload of the add method asks for a key.It also implements indexOfKey and ContainsKey yet there appears to be no way to determine the key of a node from the node itself or from any of the events you would typically use such as TreeView_AfterSelect().
Am I correct or is there in fact someway to retrieve the key from a node or event which I have overlooked? And assuming I am correct. Why on earth was it implemented in such a way? The only thing I could think of was that perhaps TreeNodeCollection.Key is deprecated? But I see no mention of this...
PS: I am aware of the TreeNode.Tag property and how it can be used to the same effect.

I'm working with a TreeView in a VB.NET to C# conversion project. I have this VB.NET WinForms code
Dim Arguments1 As String = path & "" & fs & " ls " & TreeView1.Nodes(ccc).Name
and I need the C# code. I got this far
string args = path + "\" + fs + " ls" + ...
I would assume it would be
.Items[ccc]
but there is not name attribute in that
I have been looking for a some working code for the last couple of days to set up a treeview in my WPF app to display some database data. I use VB as i am much more confident in it - which drastically limited the code examples out there. More examples i found used manually entered data to populate each node versus a database which was little help. I finally found some code which bound the each node to a query and related the query via a DataRelation. Great this should work perfect!
The example used the Northwind database so I changed it to my database and plugged in the queries. To my shock the treeview populated fine except.... all the data is invisible.
Here is the code:
Imports MySql.Data.MySqlClient
Imports System.Data
Imports System.ComponentModel
[code]....
and here what i end up with the data seems to be there but you can't see it.PS there may be some confusion as to the objects. I went back tried to keep as close to the original code as possible when i discovered the problem only replacing the queries with my own - the original code used "Categories" and "Products" where as I "use Distributors" and "Titles"

The parent nodes are populated through the table "tblINLOGNAAM" The childnodes are populated by "qryINLOGNAAM_GEBRUIKER_DR" When I click the parentnode I don't want anything to happen.But when I click a childnode I would like the ID of that name (wich is stored in the table "qryINLOGNAAM_GEBRUIKER_DR" with the name "Gebruiker_ID") to show so I can make a master detail relation with a datagridview.My problem is that I cannot get the gebruiker_id from the table "qryINLOGNAAM_GEBRUIKER_DR" when I click the childnode.

I am able to get the pnode added to the TreeView and all the node breakpoints are hit. The problem is that in the TreeView, I am only able to see the parent view arrow, the rest of the name, image, etc. are not getting displayed. It is like this: How can I fix this?
In my application, I have been getting this error each time the treeView loads it's items. This error makes my application slow on load and takes at least two minutes to load.The error is: System.Windows.Data Error: 26 : ItemTemplate and ItemTemplateSelector are ignored for items already of the ItemsControl's container type; Type='TreeViewItem'
My xaml code for the treeview is: (I'm using VB.net on my ViewModel)
<TreeView ScrollViewer.VerticalScrollBarVisibility="Hidden"
ItemContainerStyle="{DynamicResource tviStyle}"
Background="#FFF0F0F0" BorderBrush="#FFE5E2DB"

The binding of the ItemsSource is an ObservableCollection(Of TreeViewItem) thats is filled from a database.
I am making a user control named MultiSelect, which consists of a textbox. In this textbox I put substring. I want the user control to show a treeview outside the MultiSelect boundaries where items matching the substring will be shown.
For me its no problem to make a treeview inside the MultiSelect boundaries but I need to save space on the original form where a MultiSelect control will appear, so I need to do it like the treeview will appear and after I choose items, it will disappear
I'd hate to have to create my own control, but will attempt to if it comes to it.
I need to display columns within a TreeView node so I can display specific information about that item within columns.
Think of a ListView as a TreeNode. That's basically what I'm trying to get at.
I'm hoping for a relatively easy solution, but I can't imagine this would be too easy.
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 am trying to add nodes to a treeview that come from different databases, but at the moment i am just trying to add the first set from the first database.
The link between the child and the parent is the ID column in the parent nodes access database this number is in a column in the child database called Section, i am trying (unsuccesfully) to use queries and If statements.
I am assigning the ID column from the parent database to the .Tag property of the parent node and then i am trying to use an if statement within the query "asking" if the parentNode.Tag = number in section column Then Add new node, but i haven't done it right. The code is below:
While RetVal3.Read
If RetVal3(0).ToString = SectNode.Tag.ToString Then
Call AddCalcNodes(SectNode)
