VS 2005 : Treeview Check Children Code?
May 11, 2010
To set the checked state of the child node to its parents node i used this code.
mycode
vb
Private Sub CustomerFields_AfterCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles CustomerFields.AfterCheck
[code]....
I also found the following code on msdn. Whats the difference b/w the two. Both of them works
vb
Private Sub CheckAllChildNodes(treeNode As TreeNode, nodeChecked As Boolean)
Dim node As TreeNode
For Each node In treeNode.Nodes
[code]....

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.

Im new to treeviews so I hope this is not posting a problem that has been covered. I want all the children of a checked parent to also be checked. I have found various snippets that can achieve this but only for one or two levels. When I expand further than 2 levels the children are not checkeds. What am I missing? I have managed to find this piece of code that I am using in both the "AfterExpand" and the "AfterChecked" events to achieve the result. There must be a better way.

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.

Is there a way to tell when clicking on a node in a TreeView whether or not that node already has 1 level down populated within the control? That is, I have code which populates a TreeView 1 level down. I need to put some validation code which checks to see if this level has already been populated before the code that acutally populates it.

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

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 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.

so here is what I got so far. I have a treeview with multiple states as parent nodes. then as child nodes I have certain cities. as for my code - I have it set up that if I check the parent node, all children nodes will be checked. I also have code that moves the tags to listbox. the only items that have tags are the children. the code that I have works if I have tags set for the states, but I dont want to have parent tags move to the listbox. how can I change the code I have or rewrite my code to get ONLY children tags in the listbox even if the parents are checked??? hope this makes sense. here is my code
CHECKS ALL CHILD BOXES IF PARENT BOX IS CHECKED
VB
Private Sub TreeView1_BeforeCheck(ByVal sender As Object, _
ByVal e As System.Windows.Forms.TreeViewCancelEventArgs) Handles TreeView1.BeforeCheck

I'm having a little trouble figuring how to do this.I have a dataset with a single table. Each row has the following fields ProductName, Version, CompanyName
The data might look like this
Visual Studio, 2005, Microsoft
Visual Studio, 2008, Microsoft
Office, 2007, Microsoft
I have already populated the TreeView with a list of Company names from a separate table. Now, what I want to do is to loop through my dataset adding a single node for each product under the appropriate manufacturer. Then under each product adding a separate node for each version of that product.

I have a treeview and if I click on another control the hightlight disappears so I set the HideSelection to false and now the highlight row changes to a really light gray. Is there a way to have it still as dark blue. The reason being is because the user is clicking on a row in a grid and dropping it on the treeview and I need it to be clear that it will add it to the selected node which needs to be clear.
