Export error when there is custom cell editors

[Helen]

Hi,

I'm implementing custom cell editor using spreadprocessing to create a template for user to export and edit.  After they are done, they import back using the Telerik built-in import function.  I have no problem when creating the validation in the cells as I followed your example here:

https://demos.telerik.com/aspnet-ajax/spreadsheet/examples/custom-editors/defaultcs.aspx

When I tried to open the export file, I would get an error : "We found a problem with some content in "abcd.xlsx".  Do you want us to try to recover as much as we can? ..."  After I clicked 'Yes', my custom cell editors disappeared.

The same error occurs when I export from your demo.  However, if I create a spreadsheet with validation from scratch, everything works perfectly.

Please help!

Thank you,

Helen
