Check All Items Under A Parent Node In Visual Basic?

Jun 25, 2010

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

[code]....

Check Child And Subchild If Parent Node Is Checked In Treeview?

Apr 25, 2011

I 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

Treeview - Check All Child Nodes On Checking Parent Node?

Jul 6, 2011

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.)

Visual Basic (Coding) - Child Form To Open Within A Panel On Its Parent?

Mar 2, 2012

I have created a (kind of) 'Desktop' Form for the main basis of my program. Basically it is made up of 3 panel controls.

1. Holds all buttons which load the different forms (Like the windows start menu when expanded). name: StartMenuPanel

2. Holds Information on log in deatails. name: LogCheckPanel (very thin panel at top of screen)

3. Main panel which takes up the majority of the screen (where I want the forms to load). name: MainPanel

My aim is: When a button is clicked from the 'StartMenuPanel' the form will load with-in the 'MainPanel'.

I tried changing the start position to 'centre parent', but the panels are in the way so some of the childform is overlayed by the panels.

[Code]...

When I run this I get the following error: 'Top-level control cannot be added to a control'.

I hope I've explained this well enough.

Treeview Only Allow Children To Parent Node

Apr 13, 2011

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.

VS 2008 Attempting To Add 2'nd Parent Node To Treeview?

Jan 18, 2011

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
