    I have a gridview contains 2+ Millions rows and around 5 columns, I want to export the gridview as Excel or PDF document. When call export, I get rowIndex out of bound exception.

    Here is the way I used to export as Excel

    exportGridView.ExportToXlsx(stream, new GridViewDocumentExportOptions
                                                                                                     AutoFitColumnsWidth = true,
                                                                                                     ExportDefaultStyles = true,



    and this is the way I export as PDF

    exportGridView.ExportToPdf(stream, new GridViewPdfExportOptions
                                                                                                    AutoFitColumnsWidth = true,
                                                                                                    ExportDefaultStyles = true,


    Best regards,

    Hello Ahmed,

    As all data that is about to be exported is saved in memory, there is a certain limitation of the total amount of items that you can export. I suggest you check the Reporting tools for scenarios where a huge amount of data needs to be exported. You can also consider some custom logic to export the grid in parts and in separate files.
