How to reorder rows using drag & drop

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I would like to be able to allow the user to change the order of the rows in a report control by using drag & drop.   My report control is not using a tree.  It is just a simple list with two columns, but it does use the virtual mode.

I tried using EnableDragDrop(), but this doesn't work.

What do I need to do to enable drag and drop to allow someone to change the order of the rows?  What event do I catch to know when they have dropped a row in another location?

Thank you.

	I resolved the problem myself. I wasn't calling AfxOleInit() in InitInstance of the application class, this prevented the drag cursors to appear. I override the OnDrop member function of the CXTPReportControl to implement drop, since the base class doesn't support dropping when using VirtualMode. I put all my records in my own CArray and used virtual mode to display over 100,000 records! It takes a few seconds to load, but is real fast once it is loaded.
