A colleague warned me that using Modal windows for a GP AddIn causes problems. He mentioned that it messes up the tab order, but when I tried it, the window displays, but some controls (save and cancel buttons, control box) do not respond to mouse events. I basically have to use the ESC key to close the window.
Has anyone had problems trying to do a Modal .NET window as part of an AddIn?
If it doesn't work, is there a workaround for avoiding problems if the user goes back to GP and makes changes?
In my case, my .NET window is for the Vendor Maintenance form, and my data on the form is tied to the vendor ID, so I would ideally like to prevent the user from changing the vendor ID on the GP form. Modal seems like the easiest way, but I suppose I could detect a change in the Vendor ID field value and handle the situation at that point, but that seems like more work.
