Hello,
Thanks for reporting this problem. This is certainly weird to hear. The common thing between all these controls is that they are located in the same assembly.
If you are using version Infragistics 2008.2 for .NET 3.5 - the name of the assembly is Infragistics2.Web.v8.2.dll for .NET 2.0 or Infragistics35.Web.v8.2.dll for .NET 3.5. It is located in the install folder of Infragistics default installation, typically something similar to
C:\Program Files\Infragistics\NetAdvantage for .NET 2008 Vol. 2 CLR 2.0\ASP.NET\Bin
Just open your toolbox, click choose items for the Infragistics Tab on the toolbox and navigate to the DLL files and add it manually - this should hopefully resolve the problem until we check out what is going on with the installer.
