hi

Add(CI)

MyDatabaseEntities dc = new MyDatabaseEntities();
try
{
dc.Empmodeles.Add(CI);
dc.SaveChanges();

message = "Successfully Saved!";
}

finally

dc.Dispose();
}

Error:'object' does not contain a definition for 'Add' and no extension method 'Add' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?)

What type is "dc.Empmodeles"?

Look at the error message; your Empmodeles class does not contain an Add method.

Look at the defintion of your MyDatabaseEntities class, and see what type the Empmodeles property returns. I'm guessing it returns an generic object rather than a specific user or system collection datatype. If so, then you need to cast the property return to the appropriate class in order to use the Add method.
If not, then you need to look at the class type it does return and work out why it either doesn't contain an Add method, or why you think it should!

Sorry, but we can't do any of that for you!
