Hi folks

I am trying to implement some drag & drop functionality.

I have built this little chess AI (every 2nd program is an "AI" these days). Now I am trying to build a front end for it - so that you can play against it.

Screenshot-2020_2D00_04_2D00_29-at-14.33.59.png

From the above - I want to drag a chess piece to another place. Yes it is a grid and those are records (temp table), but the actual data structure is much different. Don't ask me about that please - I only need to know about drag & drop.

I haven't been able to find any useful information on the web. And my "Find references" functionality on my VM is in non-operational state (I'll make a post about it some time). So I can't find any examples in standard AX. Also - I don't know what to expect. I haven't seen it on the front end. I have overridden all the "drag & drop" related methods I could find. But I have no idea where or what to do. I can just tell you it is not working.

So I will be very thankful if someone could assist me with 1) a link 2) an example in standard AX or 3) a brief overview.

Chess is not related to D365 Finance. But Drag&Drop is indeed. I will hopefully be using this skill for a proper reason in future.

Thanks for your attention

Drag & Drop works in AX2012 but hasn't yet been implemented in D365FO.

Not sure if they would add it in the new grid control which is now in public preview (or parts of it are maybe even GA?).

I'm not sure how you implemented this exactly, with a grid or table control perhaps?. But I would expect something UI-specific like this to be done with an extensible control. That essentially lets you build all the HTML and JavaScript needed, and then your drag&drop is a simple JavaScript solution.

I can appreciate the exercise even though it's not a typical F&O thing. But my point is that any special UI like this would probably not be implemented with the standard controls anyway.

Hi Pete,

It could be a quite nice feature to spend time while waiting for an operation to be finished instead of clicking "Wait" button.

thanks, that is the answer to my question

I have a table structure that is not user friendly (for example each "Block" in the grid is a record, resulting in 64 records to define the current status of a chess game). I take these tables and "pivot" them into a temp table. The temp table has, among others, 8 fields for each column. And then for the current chess game, there will be 8 records. This temp table is a DS on the form and the data source for the grid in the screenshot. This was the quickest way I could think of to present the data. The solution will be an extensible control yes. I have created one for a signature pad integration. But it takes time and I'm lazy. So for now the user will have to specify his or her move in some text boxes.

lol. I have a Sudoku program (model) if you want it. Complete with difficulty levels, configurable assistance, a solver, a sudoku generator and configurable pay increases when you solve a sudoku. For some unfathomable reason my employer does not want to include it in one of our ISV products. Apparently it is "not professional".
