Hi,

Is it possible for me to have an entity throw an exception or something if a user trys to change the value of a field for an already existing object?

In other words, they can only specify an initial value and then not change it?

Cheers,

Ian.

I think you can use Field Validation. Please refer to the LLBLGen Pro manual: "Using the generated code -> Validation per field or per entity"

I just had the web app set IsChanged to false on the fields upon an update.
