View 10 RepliesI have a treeview with nodes being represented as checkbox.
All works fine i.e when a parent nod is checked, its child and sub child should be checked as well but it won't check only the first subchilds and i am not able to find the solution, i have debugged it many time, but still not able to figure the solution.
I tried finding the solution on the web, but didn't got the proper solution. Below is the code which i am using in my form.
Private Sub trvModule_AfterCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles trvModule.AfterCheck, trvReports.AfterCheck, trvMasterAccess.AfterCheck

View 2 RepliesI'm working on a drag-and-drop method to copy items from a listview control to a treeview. I've got the drag and drop working, but I'm hoping to limit the ability to drag items that create a child of a child. Ideally, if someone drags an item from the listview to the Treeview and the drop the listview item over a child, it would drop the dragged item to the parent.
View 4 RepliesI used both parent node and child nodes in a Tree View in visual basic 2010. Now I want user could delete a parent node if selected it or any of her childs nodes and user cant be able to delete a child nodes. How can I do this?
View 4 RepliesWhen I select a node from treeview, it correctly shows the child form. However, when I close the child form and select the same node from the parent form, nothing happens.

A form has a multi line textbox that is read line by line searching for "MSH". When found it adds that line as a parent to the treeview. each following line is added as a child. Works fine if only one "MSH" line but if more than 1 I get must clone or remove message. I did clone the message but I don't want a duplicate of what is there. I have tried several variations and have not been able to get the 2nd MSH to be added as a child but not parent.I have started to repeate code so was hoping some of you experts can point me in the correct direction. Here the section of code that partialy works.
Dim LoopK As Integer = 0
Dim New_MSH_Parent As String = "No"
Dim MSH_Node As New TreeNode() ' parent node

What node property tells you if the node in question in a TreeView is the Root Node (i.e. highest parent level)? I want to be able to test a node (True/False) in a node event procedure.
View 2 RepliesI am quite new to VB so I have a tree view and I want to know how to make it when i click a node inside a parent node it opens a URL. And on top off that I want to be able to make the nodes you click on and URL's they open while the application is open. I want it so that I made Node0 in a options form and when I click it it will open a URL witch I also set on a options form.
View 10 RepliesI'm trying to open a file via a treeview. The nodes resemble the files and folders within a (parent)folder. I also have a textbox which has the location, including the name of the (parent)folder.

View 1 RepliesI'm in need of a custom control that will allow me to do something like the attached image. It's basically a TreeView with the exception of having a row of PictureBoxes for each child node. I'd be happy with a ListView that could do this even. I tried it briefly with a DataGridView with ImageColumns but the "look" wasn't quite what I was after. I'd like the "Parent Node" text to be situated above the row of images and just can't seem to find a control that will allow this.
View 6 RepliesI was wondering how I would go about placing a check in the checkboxes for each child node of a parent node in a TreeView control, if I was to check the parent node.
For example:
Parent 1Child 1
Child 2
Child 3
If I was to check "Parent 1" how would I be able to make that event place a checkbox beside all of the child nodes of "Parent 1"? (Child1, 2, and 3.)
I 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.
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 RepliesI'm all new to this treeview business. I have a fixed treeview, very simple and basic. Only two levels, parent and child nodes. I just need two things out of this treeview.
1) If parent is checked, check all child nodes.
2) If just one child node is unchecked, uncheck parent node.
That's it! I've been looking for this for 30 mins and I cant find it. Maybe because my vb.net is old, it doesnt seem to be the same as others =/ I'm using vb.net 2003.
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.
View 5 RepliesI 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.

Is it possible and if so, how does one go about doing such a thing. I am loading a network directory in a treeview. Can the parent node be disabled, meaning it can't be selected, it's available for viewing only, but leave the child nodes selectable?
