    Hello Team,

    I am using Rad grid, that is having more then 100000 records with 70 columns, 

    I tried with even 10000 records only to check export issues but, Export to excel is not working, it slows down the page, and after waiting for 20 mins, its still not exporting the data.

    Can anyone help me out with this?

    Thanks and Regards,
    Ruchi Patel

    We strongly recommend not to export large amounts of data since there is a chance to encounter an exception (Timeout or OutOfMemory as it is in your case). RadGrid is not suitable for such scenarios and therefore we suggest that you limit the number of columns and rows.

    However, you could try using Telerik document processing Libraries. Thanks to these libraries you can directly traverse your datasource and generate the XLSX file which supports more than 65,000 rows unlike the BIFF format which is an older and more limited one. You can examine our online documentation which would help you get started easily.
