Now we are facing issue with DevExpress grid controls with ASP.NET Zero. We created API and it is fetching the data as json. We could not pass the data to the DevExpress Grid control. The same functionality is working well with DevExpress and .NET without ASP.NET Zero.
ASP.NET Zero is giving problem to us. I am sharing the error below. We need right solution for this to use ASP.Net Zero wiht DevExpress Grid controls and other controls.
System.ObjectDisposedException: Cannot access a disposed context instance. A common cause of this error is disposing a context instance that was resolved from dependency injection and then later trying to use the same context instance elsewhere in your application. This may occur if you are calling 'Dispose' on the context instance, or wrapping it in a using statement. If you are using dependency injection, you should let the dependency injection container take care of disposing context instances.
