So the current application has existing code that has a UI designed in a tree view. The objective is to design the new application with a grid view.

When designing the application does is have to be programmed on the back end to present the data as a grid or can this just be handled on the front end. The data will be dynamic…

Up to you.

I work on a large scale data acquisition system. A lot of the code that does the heavy lifting is in the GUI bits of the program. This is frustrating and has lead to numerous cases where changes and upgrades take a LOT longer then they should have. You have your backend logic, the GUI is just a means to display it.

I really appreciate the responses. And do not expect anyone to write the code. The code is old code and has been re-factored but its been built on an old foundation. The tree view presentation is old and not current…I was just curious is other programmers have run into a similar issue where in using tree views interconnected with back end due to functionality…that it was just easier to gut and lay down a new code foundation to improve functionality and efficiency.

Keep those as far apart as you can. You should be able to put a new front end on the back end code with minimal changes, and be able to access and use the code outside of the program. Easier for sharing modules. It is a painful thing, but it will save you time in the future.
