To any Infragistics users:  

My team here is trying to use Microsoft's Test Manager for automated testing of our application, which uses the Infragistics WinGrid in a number of places.  We cannot seem to select a grid cell to operate on within the tests--doing so hangs the Test Manager.

Has anyone out there had success automating the Infragistics grid in Test Manager?  Any tips or tricks to share?

Conversely, what test automation tools has anyone had success with?  Perhaps there is a different tool we should be using?  (I know Infragistics, via their Test Advantage product, is supposed to work well with HP's QTP, but we have issues getting QTP to work properly with basic .NET controls so it doesn't appear to be an option...)

Any advice is appreciated...

Thanks,

Ken
