With SpreadsheetGear controls, a 6,000 KB Excel workbook is loaded into the WorkbookView control in less than a second. This is over 100 times faster than other controls being tested so far.
Robbe Morris (Microsoft MVP - C# Co-founder of EggHeadCafe.com and former Gartner Sr. Software Engineer) says "ASP.NET and Microsoft Excel is a dangerous combination. ASP.NET and SpreadsheetGear is a match made in heaven. When you need your web or Windows app to interact with Excel files with lightening speed and no COM crashes, SpreadsheetGear for .NET is what you use. This product truly separates the men from the boys in the spreadsheet control marketplace."
With one safe managed assembly, SpreadsheetGear 2009 enables developers to easily add scalable ASP.NET Excel Reporting, dynamic Dashboards from Excel Charts and Ranges, powerfulWindows Forms Spreadsheet Controls, comprehensive Excel Compatible Charting, the fastest and most complete Excel Compatible Calculations and much more.
Simon Black (Software Architect, Nokia) says "SpreadsheetGear for .NET is a fantastically powerful spreadsheet component which is very easy to use and expand. We delivered our mandatory customer requirements well before time so we had plenty of time to implement the nice-to-have requirements nobody ever manages to deliver."
I will be evaluating SpreadsheetGear control this weekend so will post more details soon but initial feedback from top architects sounds very impressive.
