I'm encountering a problem where the UltraWebGrid Export function is taking several minutes to respond. I'm rendering the grid to a standard aspx page along with a "View as PDF" button. Clicking this button triggers a postback which sets some style properties and then the following:
objExporter.ExportMode = Infragistics.WebUI.UltraWebGrid.Exporter.ExportMode.DownloadobjExporter.Format = Infragistics.Documents.Reports.Report.FileFormat.PDFobjExporter.DownloadName = FilenameobjExporter.Export(objGrid, objGridSection, objMS, True)
It's the last line where things get hung up. Interestingly, if I skip adding the grid control to the page on post back, the PDF loads nice and quickly. It also doesn't display all of the styling so this isn't a great option. Also, most of our reports are in a Reports subfolder. Those few that are in the root folder also load nice and quickly. Not really sure why this would make a difference, but any insight here would be appreciated.
The UltraWebGrid is part of an old toolset, that was retired in 2011. We are not longer eligible to provide support for that. I can recommend to investigate differences between pages that load the pdf nice and those that hang out, there should be a reason for the behavior.
