I have a class, let's call MyClass. In this class, I have a TreeView property let's call myTreeView..In my code, I populate the Nodes of this TreeView so I can use it later on.Then, when it's time to actualy use it, I haven't been able to take all the nodes from myClass and put them in a Tree View Control on my form.[code]The weird thing is that when debugging, the TreeView in MyClass is well populated with the proper values and in the loop, newNode isn't empty, there's actually something but for some reason it's not showing anything.

I'm trying to do treeview checkbox function in Visual Studio 2005 using VB.Net. I have successfully loaded the treeview checkbox as you can see in my attachment. But the problem starts here. I have designed the form before I inserted any code inside of it so my programming is mainly trying to connect to the instance in the design.
This are the following function I want to perform on the treeview checkbox:
1. When I select the ITAD checkbox, all the nodes under it will be checked automatically
2. When I select the Raw checkbox, all node under it will be selected.
I had a treeview that had checkbox and its content is like file explorer. the checkbox is check when users want to delete that files or directory, after the selection, press the command button then all selection will be process (on this case deletion) how that to be code?

I have been working with VB 6.0 for years. I am converting an app that uses treeviews to VB.Net 2008. The way it use to work the tree grid started with a list of the drives on the system. Left click drilled down in the selected drive or directory. Right click would perform an action with the selected drive or directory. In VB.Net it appears you can only select with left click using the AFTERSELECT event. Is there a way to select a node with right click?
View 1 Repliesfor some reason I have to click a node in a treeview twice for it to register as selected. I've checked with treenode.isselected() and treeview.selectednode() and with both two clicks is required to show the selected node (1 click continues showing the previously selected node as selected) while the visual highlight/selection works perfectly with 1 click. Any suggestions on what may be wrong/how it could be fixed? (The node selection code is in the nodeclick event)
