Check Child And Subchild If Parent Node Is Checked In Treeview?
Apr 25, 2011I 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 RepliesTreeview Only Allow Children To Parent Node
Apr 13, 2011I'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, 2011A 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.

View 1 RepliesCustom TreeView - Display Parent Node Text Above Row Of Images
Jun 9, 2010I'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 RepliesTreeview - Check All Child Nodes On Checking Parent Node?
Jul 6, 2011I 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.)
VS 2005 Add A Node To Treeview?
Mar 23, 2010I 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.

View 4 RepliesChecking Treeview Nodes - If Parent Is Checked Check All Child Nodes
Aug 31, 2011I'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.
