   According to the explainment  to https://forum.codejock.com/member_profile.asp?PF=2135&FID=38 - freediver211    ,  I think  the  "VirtualMode" is just a method to copy the "data " from the database to the "Screen "—— it is not need to get the data to the  "ReportControl ", and  when needed , it can get the data repeatly from the  database,  for instance ,   in your demo , though you were not get a data form the "third part ".
 
      but  there could be some prolbem by comparing to other grid controls . In your demo , your printf the grid like this:  in a row ,  print the column from the left to the right , when a row has finished ,begin a new row ,   print the column from left to right, …………………… 。 The problem is ,in you function that do above ,  the print sequence has been "defined" ,   how can I  get/set  "the one" among the table ???

Call RedrawControl and all visible report cells will be repopulated with the new data from your methods.

yes, you think correct, but just look further -- you change your "the one" somewhere in your data; all others left the same; on every new redraw, or when it is necessary, Report asks you values of all those items, including old unchanged ones, and new changed ones.
