    SpreadsheetGear 2012 comes with the SpreadsheetGear Explorer sample solutions for C# and Visual Basic. The SpreadsheetGear Explorer is a helpful Windows Forms Application sample soluton for Visual Studio 2005, Visual Studio 2008, Visual Studio 2010, Visual Studio 2012 and Visual Studio 2013. See SpreadsheetGear Explorer Sample Solutions for more information.
  • How do I use SpreadsheetGear 2012 in a Visual Studio 2005 / 2008 / 2010 / 2012 / 2013 or Visual Web Developer Express Edition Web Site Project?
    Follow these getting started instructions and then refer to the live Excel Automation Samples for ASP.NET.
  • How do I add the SpreadsheetGear 2012 Windows Forms Controls to the Microsoft Visual C# 2005 / 2008 / 2010 / 2012 / 2013 Express Edition Toolbox or the Microsoft Visual Basic 2005 / 2008 / 2010 / 2012 / 2013 Express Edition Toolbox?
  • Can multiple versions of SpreadsheetGear 2012 be used at the same time on one machine?
    Yes. SpreadsheetGear 2012 includes strong named assemblies which enables the installation and use of multiple versions on one machine.
  • Why don't I see SpreadsheetGear listed under the .NET tab when using Add Reference?
    Visual Studio only looks for new .NET components once. Be sure to close and restart Visual Studio after installing SpreadsheetGear 2012.
  • Why does the IntelliSense and Dynamic Help not work in Visual Studio?
    If you recently installed a new version of SpreadsheetGear, you may need to remove any references to SpreadsheetGear assemblies from your project using the Solution Explorer window in Visual Studio. First, remove any old references, then, add any new ones back by using the .NET tab of the Add Reference dialog.

    It is also important to note that Visual Studio 2010 replaced the MS Help 2 system with the new Microsoft Help Viewer 1.0 system. This new help system does not have Dynamic Help, though it does still support IntelliSense, and pressing F1 on a term such as "IWorkbookSet".

    See SpreadsheetGear 2012 -> Getting Started -> Using Help in the SpreadsheetGear Help for more information on using the SpreadsheetGear 2012 help with Visual Studio 2005 / 2008 / 2010 / 2012 / 2013.

    Note: It may be necessary to delete any occurences of any SpreadsheetGear assemblies from your project directory before adding any new assemblies.
