I recently finished quite a complex form containing several grids in a tabbed control on a window. What strikes me is just how much stuff is all built into WinDev which you dont have to program whereas in VFP you would. For example, here is a list of stuff that is built into WinDev Windows and Controls which do not require any programming from you at all (only setting options on/off as desired):

Window - move by the click and hold on the window background
Window - transparent areas
Window - support for skins/themes
Window - remember size and location
Window - auto grey/dim if inaccessible
Window - open/close animations or none
Window - copy or paste the form
Window - drag and drop support

Grid - Sort ascending / descending on any column (no programming or even creating indexes required)
Grid - Search within a column
Grid - Search the entire grid, all columns, with word highlighting
Grid - Export a row, a column, a cell, entire grid to Excel, Word, PowerPoint, XML, PDF
Grid - Copy a row, a column, a cell, entire grid to clipboard
Grid - Print grid contents
Grid - convert rows to display over several lines if too long to fit in column
Grid - Remember column locations and sizes
Grid - Restore default size, location and columns
Grid - Filter on any column using like, not like, contains, does not contain, etc.
Grid - Store the filter for future (like recently used list)

Tab - Remember last used tab

Radio buttons / Checkboxes / etc. - remember the last values used

There's more but this gives you the idea. All this happens as built into WinDev windows and controls - no programming.
