Hello, I recently am getting an error with a datasource control, in the designer view only. The application sometimes builds and runs just fine (data is displayed in the gridview), but I get the error with the icon in the design view. I tried deleting and recreating the datasource, and again it first appears fine and then I get the error.

I am using LLBLGenPro 2.6.0.0 and Visual Studio 2005 Sp1. (.NET 2.0.05727)

I generated my classes using Adapter, with Template bindings SD.TemplateBindings.OracleMSSpecific.NET20

The datasource was created from a database view that was added to LLBLGen Pro as an Entity.

The datasource at first appears fine and I am able to choose the source and configure properties. And the application builds and runs. But then the error below appears and I am not able to access the properties box.

Error Creating Control- _ContactInfoschoolinfoDS 'cep.FactoryClasses.Contactinfoschoolinfoview_EntityFactory, cep' could not be set on property 'EntityFactoryTypeName'

Thanks for any suggestions, Carol

Thanks for the reference, I had seen something similar, although not exactly this posting.

Followed the suggestion which recommended:

• close pages in vs.net, so no page is open in the design view
• clean solution
• Rebuild solution in full
• open page in html
• switch to designer

And I did try closing all pages, cleaning and rebuilding the solution, but still have the same problem. I also tried changing the data source configuration, in case there was a problem with the view I selected.

I will try regenerating the classes in LLBLGen and starting again with a new page--new gridview and datasource. But other than that, not sure what to do. I'm a bit of a Visual Studio novice.

Thanks! Carol

Please make sure your application references the same version of the OrmSupportClasses as the one used in Visual Studio toolbox.

I checked the little gear icon for the LLBLGenProDataSource2 in the toolbox, and this control for adapter is version 2.6.0.0, the same version as my OrmSupportClasses. I didn't go to the file structure to actually locate anything and verify further. Is there another place I should be checking the version of OrmSupportClasses used by the Visual Studio toolbox?

I also deleted the gridview I was using as well as the datasource, and after deleting everything, closing forms and rebuilding, and then adding back first the datasource and then a new gridview, things seem to be fine. It has worked all morning, so I think all is well.

I will try and document carefully if this problem comes up again, as I'm not sure just what changed to make things work.

Thanks for your help, Carol
