Question

I have a base recipe class and I am using a datacontext. I overrode the insert method for the recipe in the datacontext and am trying to insert into its children. Nomatter what I do I cannot get the child to insert.Currently, just the recipe inserts and nothing happens with the child.

    partial void InsertRecipe(Recipe instance)     {         // set up the arrays         for (int x = 0; x < instance.PlainIngredients.Count; ++x)         {             instance.TextIngredients.Add(new TextIngredient()             {                 StepNumber = x + 1,                 Text = instance.PlainIngredients[x]             });         }          this.ExecuteDynamicInsert(instance);     } 

I have tried everything I can think of. I even instantiated another datacontext in the method and after the instance came back from ExecuteDynamicInsert with the id, tried to add it, and I get timeout errors.

I figured it out. Override SubmitChanges in the DataContext, and find all of the inserts and updates that are recipes. Run the algorithm to add children there.

    public override void SubmitChanges(         System.Data.Linq.ConflictMode failureMode)     {         ChangeSet changes = this.GetChangeSet();          var recipeInserts = (from r in changes.Inserts                        where (r as Recipe) != null                        select r as Recipe).ToList<Recipe>();          var recipeUpdates = (from r in changes.Updates                        where (r as Recipe) != null                        select r as Recipe).ToList<Recipe>();          ConvertTextData(recipeInserts);         ConvertTextData(recipeUpdates);          base.SubmitChanges(failureMode);     }
