问题
I have some data I want to display in a StringGrid. This data contains many rows with some pretty static columns but also two columns that need web-API lookups and take some time to gather. SO when I try to set these cells in the OnShow of the StringGrid (or any other "Init") I get a long delay until the cell values are set. What I would like to do is only look up the values for those cells that are currently displayed (and not all of them at once).
How Do I find out which rows are currently displayed? Is there an event I can use?
