Dear team,

as you shown in image ,we are trying to download the document  (Excel Doc.),

after click on download file was save as without document format (without extension)

version used   =  DocumentUltimate-v5.9.7.0

I tried code below  

  DocumentViewer DocViewer2 = new DocumentViewer();
                        DocViewer2.DocumentSource =  new DocumentSource(new DocumentInfo(Convert.ToString(docpath), docpath), databyte);
                        DocViewer2.DocumentFormat = GleamTech.DocumentUltimate.DocumentFormat.Xls;
                        DocViewer2.SidePaneVisible = false;
                        DocViewer2.DownloadFileName = Convert.ToString(uniqueId);

please guide me
