When 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.
Private Sub TreeView2_AfterSelect(sender As System.Object, e As System.Windows.Forms.TreeViewEventArgs) Handles TreeView2.AfterSelect

View 2 RepliesI have a TreeView that I am using for display purposes only. I don't want the user to be able to select any of the nodes. Setting the enabled property of the form to False doesn't suffice since it changes the entire look of the nodes.
I tried canceling the select action in the BeforeExpand event. It kind of works. It selects, then de-selects the item. I'm going to play around with other events to see
I'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 10 RepliesA 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"

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 1 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.

I'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.)

View 2 RepliesI'm simply trying to parse a SOAP Response and pull out the ResponseCode and UnconfirmedReasonCode Elements out of the following XML:
[code]...
New to XML. I have a 3rd party webservice that supplies an XML document that I have to update the element values and pass back. The core issue issue is I get an NullReferenceException error when calling the node.RemoveAll() method in the code below. I'm calling the RemoveAll() method because each element has the xsi:nil attribute when it is supplied to me, and if I don't remove it before updating the element value, the XML won't validate by the webservice.The XML document supplied by the 3rd party webservice is as follows:
<?xml version="1.0" encoding="utf-16"?>
<TaskData xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://schema.sample.com/application/1/520800B">

I've seen have used the XmlNamespaceManager, but I haven't been able to make it work. This xml document has a namespace specified for the TaskData element, and a different namespace for the RequestInfo element. I tried specifying the XmlNamespaceManager variable for each namespace, but got the same results....hovering over the nsmgr variable while in break mode reveals that the "children could not be evaluated" and that the DefaultNamespace property is an empty string.

Dim f As String = C:UsersTom BluewaterMusic
Dim d As String = Path.GetDirectoryName(f)

And that's not exactly what I want. In this case, the Music folder won't be selected. I could search this place for a clue. But there was no hit. It seems that the search function doesn't always work here.
