vaibhavgg,

I know it's been 5 months, but any chance you can share your changes (ie the code)?  We are having the same issue and this is the last of the bugs with GZIP.  Also, have you noticed similiar with the document exporter and PDF's.

Thanks in advance for your help.

Great - thanks for sharing the solution in public forums, much appreciated. I will add this to the list of known potential problems, since I am sure a lot of people will find this useful.

Thanks again.

Hi Rumen,

Thanks. Before sending the webgrid for export to excel. change the Response.Contenttype. and in global.asax file check the content type and change the setting of compression type.

It works fine for me.

 Thanks

Hello,

Some technical information about the export can be found here:

Maybe you can use the application/ms-excel MIME type of the exporting (downloading) operation and check for it  in global.asax.

Hi Ivan,

Thank you for reply.

but how can i disable compression only of export?

do you have any sample code?

On button click i export the grid data in excel. for e.g. UltraWebGridExcelExporter1.Export(UltraWebGrid1)

app.Response.Filter = New DeflateStream(prevUncompressedStream, CompressionMode.Compress)

app.Response.AppendHeader("Content-Encoding", "deflate")

ElseIf acceptEncoding.Contains("gzip") Then

' gzip

app.Response.Filter = New GZipStream(prevUncompressedStream, CompressionMode.Compress)

app.Response.AppendHeader("Content-Encoding", "gzip")

End If

End Sub
