I'm evaluating EntityDac.

I would like to know how to make the entity property setter run when a value of an EntityDataSet field is modified.

I would also like to know what strategy to perform validation rules for a given entity before the data is sent to the database when the SaveOnPost property of EntityDataSet is turned on or when SubmitChanges is called in context.

If I modify the values directly in the entity, everything works fine, but when I need to use an EntityDataSet, everything seems to follow a different path.

I need to use the EntityDataSet for controls that do not support LiveBinds, such as devexpress.

Additional info: Im using Attribute-mapped objects

Could anyone help?
Not a good start considering I'm evaluating this product. I opened a ticket on this subject and until now I got no answer.

Attribute-mapped objects have certain limitations comparing to the Code Mapped Entities available in our product. We will consider the issue of overcoming some of these limitations, and especially those listed in your description. For a detailed and complete analysis of the issue, please compose and send us a sample that demonstrates the Attribute-mapped issues which you encountered when developing your application. In addition, we will need the model used in this sample. Please use the e-support form (https://www.devart.com/company/contactform.html)
