We tested RadSpreadsheet by setting and getting 10 000 values in cell range that is 100 x 100 cells. The operations were performed for 619 ms.
We used this piece of code to test the performance:
DateTime startTime = DateTime.Now;
i = 0; i < 100; i++)
j = 0; j < 100; j++)
radSpreadsheet.ActiveWorksheet.Cells[i, j].SetValue(i + j);
TimeSpan totalTime = DateTime.Now - startTime;
That said maybe you are setting different kind of data. If so, please open a support ticket and send us a sample project or sample data. This way we will be able to investigate the issue you have encountered on our side.
Thank you in advance for your cooperation!
