I'm looking for an easy way to count the number of selected cells in a
stringgrid.
Is there anything like a selected property for each cell?

To know if a cell is selected you can use
  AGrid.IsCellSelected(x, y)
If instead you want to get the range of selected cells, use
  AGrid.Selection
which returns a TGridRect with the coordinates of the selected
"rectangle".

Or, if you have multi-range selections active, you can use:
  AGrid.SelectedRange[Index]
along with
  AGrid.SelectedRangeCount


HTH!

Thanks, Lucamar, for this tip.
Meanwhile I made a little routine for counting the selected rows (if
rowselect=true). s.b.

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i function
SelectedRowCount (theGrid: TStringGrid): Integer;var i     : Integer; 
  iCount: Integer;begin   iCount := 0;   for i:=0 to
theGrid.SelectedRangeCount-1 do      iCount := iCount + 1 +
theGrid.SelectedRange[i].Bottom - theGrid.SelectedRange[i].Top; 
 SelectedRowCount := iCountend;
