I have recently reinstall Visual Studio, open my project and added a Syncfusion GridControl. When I compile my project, I have this outpout: Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object. at Syncfusion.Core.Licensing.FusionLicenseProvider.GetLicense(LicenseContext context, Type type, Object instance, Boolean allowExceptions) at System.ComponentModel.LicenseManager.ValidateInternalRecursive(LicenseContext context, Type type, Object instance, Boolean allowExceptions, License& license, String& licenseKey) at System.ComponentModel.LicenseManager.ValidateInternal(Type type, Object instance, Boolean allowExceptions, License& license) at System.ComponentModel.LicenseManager.Validate(Type type, Object instance) at Syncfusion.Core.Licensing.LicensedComponent..ctor(Type type) at Syncfusion.Windows.Forms.Grid.GridControl..ctor(GridModel model) at Syncfusion.Windows.Forms.Grid.GridControl..ctor() It is a problem of Licensing because I work with the evaluation version Is This system of system of Licensing integrated in the full version ?

I have actually the same exact problem in a project that I upgraded from to I also have a webservices which even if I disable it that makes no difference. I have the nullexception on one form, but if I add a new form and put syncfusion stuff on it in the same exact project, that new form works perfectly, but as soon as I open the old converted one, it gives the nullexception again. I even put back code to access the webservices and the new form and it was working just right. I think that turning webservice off to make it work was a pure coincidence. I doubt that the webservice has something to do with it. I beleive it''s something with the resource file. That''s my point of view. That''s a sure headache problem and I''m hungry for a fix! ;-) Cheers, Mike

Hi Jonathan, Mike As per Stefan''s posting in the forums: http://www.syncfusion.com/Support/forums/message.aspx?MessageID=28002 we now have an internal build that we are currently testing. Jonathan, I created Direct-Trac incident and updated it with download instructions and an unlock key. (incident: 18182) Mike, if you want to get this build, kindly open a support incident. Note, that we are still internally testing this build and we hope to ship it as soon as possible. Thanks once again for your cooperation. Regards Arun

Thanks Arun. Actually, I already have Direct track incident #17889 and #18093 with no really conclusion. You could easely put it there. Best regards, Michel
