I am getting a NullReferenceException when trying to do a SaveToExcelFile.
I have attached some screenshots that show that GridWeb1, WebWorksheets and docURL are in fact NOT null. I have also included the error text and the aspx and cs file in question.
Please provide us your source file (xls/xlsx) which is throwing exception.
The file you are loading in a gridweb and then saving back using the save command button.
Since, I am unable to run your project, will you please provide a simpler runnable code without any dependency of Telerik controls? It will help us sort out your problem quickly.
Creating a separate project is something that I will try and get to you soon. For now, I have attached the xls that I am loading and then trying to Save to. Jim
It seems, you have provided me output file. I require your source file to see if this issue could occur with the latest version: Aspose.Cells
for GridWeb v2.7.5.2001
