  • Where to begin... this seems like a very broad question. What might be better is to post some specific code segments you are having trouble figuring out and asking some more specific questions. Otherwise it's hard to know how to begin answering this.

  • Hi Rahul,

    I agree with Justin - there is not enough information about your problem. What kind of extensibility do you use - add-in or package? Could you please describe what do you working on?

  • Hi Guys,


    I am using VSIP(Package) for this....



    We have created a new hierarchywindow which contains some dataItems in tree structure. We do have some editors which are helpful to edit the items within their specific editor...and some editors can have other items to be refered and we need drag-n-drop over here.


    As prevoiusly, we were using TreeView windows control it was working fine, and when we implemented this HierarchyWindow, we are not able to implement this and this became a critical problem for us.



    we need to have our new solution explorer to enable drag-n-drop between the HierarchyWindow and the user controls of the editor..


    So, after going through with MSDN, I found two interfaces




    Which needs to be inherited for the implementation.


    Your help will be higly appreciated.


    If you need something else, please feel free to contact me.

  • Hi Rahul,


    I'm still a bit unclear as to what exactly you are attempting to accomplish.


    Where does this drag operation start, and what window are you attempting to drop to?


    When you say HierachyWindow, are you reusing the VsUIHierarchyWindow in a custom toolwindow implementation? And are you attempting to drag items from this window to somewhere else? If so, where?


    Or are you attempting to drag items from somewhere else to this toolwindow?
