Where is the last version Package ASP.NET

Can anyone provide a link from the last version from ASP .NET package?

I downloaded from docs.dhtmlx.com/doku.php?id=dhtmlxgrid:excel but i guess this version is outdated.

Iam open class ExcelWritter and i found full methods commented (eg.:insertHeader) … exists some new version with all finished methods?

the latest version of the export tool can be downloaded from here
s3.amazonaws.com/uploads.hipcha … 121115.zip

However, insertHeader and insertFooter still hasn’t been implemented. Currently export library for ASP.NET doesn’t support inserting images in header or footer
