I have a page with a Grid control to list some data (version 16.3460.0.21).
The grid is working as expected: pagination, sorting, column choose, search (Excel type) but I've found a situation that throws an excepcion and I have no clue of what's happening.
There are about 700 rows in the table and have a pagination of 12 rows per page. Excel and Pdf exporting are working as well... except under a unique situation:
If I put a simple "L" in the Make column search box, the list of searchable items is updated with rows which make contains L:
Curiously, it includes the items with null or whitespace (I don't understand it, but doesn't matter for the moment) and the list is updated with the search parameters:
Ok. Now if I try to export my list to Excel (or Pdf), a NullReferenceException is thrown when calling to the IWorkbook.Export method.
The exception does not bring too much information about what's happening
If I open again the search dropdown and uncheck the whitespace option, the filter succeed again and the export
works withou exception.
The Make column is nullable but this shouldn't affect to the results.
How can I know what's exactly producing the exception and/or how to fix it??
Thanks in advance
