Range.AutoFill Question


I have a question about Range.AutoFill functionality.

Workbook workbook = new Workbook();
// Get the first Worksheet Cells.
Cells cells = workbook.Worksheets[0].Cells;

// AutoFill bottom -> up 
  cells["B10"].Formula = "=A10";
  Range source = cells.CreateRange("B10");
  Range target = cells.CreateRange("B1:B10");

// AutoFill top -> down
cells[“D1”].Formula = “=C1”;
Range source1 = cells.CreateRange(“D1”);
Range target1 = cells.CreateRange(“D1:D10”);

//Save the Excel file

in the code above you can see two usage of autoFill usage, top-down bottom-up
Seems like there is a different behavior in these two scenarios, when the target range includes the source range (top-down fails, while bottom-up succeeded). please see attached result file.

book1.zip (6.9 KB)

Any ideas?

Please change codes as
cells[“D1”].Formula = “=C1”;
Range source1 = cells.CreateRange(“D1”);
Range target1 = cells.CreateRange(“D2:D10”);

Thanks for your replay.
I know your example will work, the question is why isn’t working the way when doing top-down vs. bottom-up)

There is an issue to auto fill data if the range area intersected.
