Hi,
I have a problem with the data access designer configuration for a readonly triggered column.
I tried to set column property "kind" like "Calculated" but when I tried to save a record of this table, the value changed anyway.
After that, I tried to change, in Model Operation settings, the value of "IsBackendCalculated" to true but, again, when I saved the value changed anyway.
After, I tried to set column property "kind" like "PersistentReadOnly" but when I tried to save I have this exception:
"An exception of type 'Telerik.OpenAccess.Exceptions.InvalidOperationException' occurred in Telerik.OpenAccess.Runtime.dll but was not handled in user code
Additional information: The update of field 'CentralScada.DAL.OpenAccess.DomainModels.Equipment._isMonitored' is not allowed."
Have you got some advices for me? I use the database first approach.
Thank you.
