I am the developer of a large .Net Web application that uses the Aspose Grid spreadsheet control on numerous pages. I develop it on a VISTA machine and it is run at my Customer's location. I have been making changes to this system and sending updates for about five years now. Yesterday, the build I sent stopped working correctly at the customer's location but still works fine on my machine.
Specifically, the control's updateData() method does not appear to be working. The following line in my Page_Load method executes on my end but it seems like it is not executing on their end:
cmdSave.Attributes["onclick"] = "dgDetail.updateData(); return dgDetail.validateAll();";
The symptom: Their users type information into the control and click the cmdSave button and the content of the spreadsheet reverts back to original data. I populate the spreadsheet from a dataset, and the above updateData() updates the dataset from the spreadsheet before I save the dataset back to SQL.
But this isn't happening at their site - and it WAS working just fine. What would cause this to happen?
Thank you for your time and attention.
