  Dynamic Data Custom Validation Validation summary

  Jun 19, 2010 03:10 PM|LINK

  Hello

  I am working with  a dynamic data site and there are some business rules I should validate before allowing an insert of new data or update

  I am working with the list details page and I have the default dynamic validator to validate the details view1 and a summary validation control

  My issue is I am able to validate but unable to display the error message in the validation summary, I get an unhandled exception, the exception is thrown but it is not handled by the validation summary

  any idea how can I achieve this

  This is what I am doing for the validation( I am using linq to entity or the ADO.Net framwork EFv4)

   public partial class MYDataContext
     {
         partial void OnContextCreated()
         {
             this.SavingChanges += new
                 System.EventHandler(OnSavingChanges);
         }

         public void OnSavingChanges(object sender, System.EventArgs e)
         {
             var stateManager =
                 ((MYDataContext)sender).ObjectStateManager;
             var changedEntities = ObjectStateManager.GetObjectStateEntries
                 (EntityState.Modified | EntityState.Added);

  
             foreach (ObjectStateEntry stateEntryEntity in
                    changedEntities)
             {
                 if (stateEntryEntity.Entity is MyEntity)
                 {
                     MyEntity uoc = (MyEntity)stateEntryEntity.Entity;
                     ValidateOutageCode(uoc.field1, uoc.field2);

                 }
             }
         }
         void ValidateOutageCode(string field1, string field2)
         {
             if (field1 == field2)
             {
                
                     throw new ValidationException("the error message I like to display in the detailsview ValidationAttribute summary");

  
             }

         }

     }
