Does infragistic v6.3 support MS office 2007 excel format (xlsx)?
And does v8.3 support both xlsx and xls?
Thanks
Excel 97 .XLS file (BIFF8) format has been supported on ASP.NET (with 100% Managed code) since version 3.1.
Excel 2007 .XLSX file format was not supported in 6.3.
Excel 2007 .XLSX file format support was added in ASP.NET 8.3 assembly builds 8.3.20083.2115 and later (this was a service release). If you have 8.3, make sure you download the latest service release to ensure you have this functionality.
Support for Excel 2007 .XLSX file format also requires CLR 3.0 or higher, however please see the note in this help topic on using the Excel 2007 .XLSX file format with CLR 2.0.
