This issue has been logged as CELLSNET-40474.
Please provide us your sample project. We will check it soon.
And we think you have to add the range to Cells.Ranges list after you create range.
Please see the following code:
Range range = w.Worksheets.GetRangeByName(“L_1_1”);
// then insert rows
We do not add the range to Cells.Ranges list for performance issue .So inserting rows/columns/ranges will not change the generated range if you do not call Cells.AddRange method.
Please also download and use the latest version: Aspose.Cells for .NET v188.8.131.52
a) How to make code work:
Please change your code as the following :
Range range = _oAsposeWorkbook.Worksheets.GetRangeByName(“L_1_1_1”);
b) Why did we change it.
We could not update the range object if it’s not in the cells.Range list.
For performance issue, we did not add named range to cells.Ranges list.
There are too many named ranges in the files of some customers . These ranges will consume too much memory.
