select node from dynamic treeview

Question

I am creating some treeviews at runtime and need to get value of the nodes that have been selected in one of these treeviews. How can I accomplish this. A google search did not return any useful answers.

Hello and welcome to Stack Overflow! You have to supply us with some code, and a more thorough explanation of what you want and what this "value" is that you want to get. A good read is also [How to ask](http://stackoverflow.com/help/how-to-ask) and [How to create a Minimal, Complete, and Verifiable example](http://stackoverflow.com/help/mcve). — Visual Vincent, Apr 28 '16 at 05:27
A `TreeView` is a `TreeView`, regardless of whether you add it to the form in the designer or create it at run time. Once you have a reference to that `TreeView`, you only use it one way. That simply means that, when you create the `TreeView` at run time, you need to keep a reference to it somewhere that you can access later on. That might be in a `List(Of Treeview)` or something else, depending on what is most appropriate for your situation. — jmcilhinney, Apr 28 '16 at 05:32

I am using a context menu to popup t allow me to shift node along with the data attached to it to another location. the data handling is being done in excel so i needed to get all the information of the node.

the problem that i face now is that i am not able to directly right click on a node to get the context strip if done the first node gets selected and not the one that was clicked how can i resolve this issue.
