i need to check all child node when the parent node is checked and i had do research from the internet but it seem that i had a error which is Type 'MSComctlLib.Node' is not defined.do i need to import any reference? [code]
View 4 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

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.

I have a tree view in my project with a parent node and with theoretically speaking infinite child nodes.
Now I want to delete the last child node from the tree view when the user presses a certain button. I thought I could do this trick with this code:

How can i check if only the checkbox is checked without having the user select the node.
This code works, but the user has to check the itm first

I am trying to check all the childnodes under a parent node, the code I have so far only goes about 2-3 levels deep in the TreeView and I am looking to grab all nodes no matter how deep they are.
Below is the code:
Private Sub CheckChildNode(ByVal currNode As TreeNode)
'set the children check status to the same as the current node
Dim checkStatus As Boolean = currNode.Checked
For Each node As TreeNode In currNode.Nodes

I 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 need to modify a xml file (actually a .rdlc report file) and add some nodes which have a lot of children nodes (and those children nodes again have children nodes). Actually they are almost the same strucutre, like this one:
<TablixRow>
<Height>0.23622in</Height>
<TablixCells>
[Code].....
and it will add my specified NS. (like I said, XElement.Parse(string) won't add it) So now I can construct the correct node. For my second problem I still can't figure out: I can't navigate to the target node by using the element name since it won't search for correct NS.
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 have a TreeView with a parent node and two children node. Each of the nodes contain a checkbox stored in a TreeViewItem. I want the two children node checkboxes to be set to IsChecked=true when the user checks the parent node and I want the two children node checkboxes to be IsChecked=false when the user unchecks the parent node.

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.
