How to save fields to the table and prepopulate them to next window?

Hi Team

I have this front end fields and will share my code, basically need to find a way when the recipes loads. I need to find each product its specific color for that but it must be pulled from the database, i dont have the column for colors. Then i must be able to save these fields to the table. [dbo].[Adr_Batch_Suite].[Premix_Control], so that when i click Preview button, i can able to see these saved fields in this window, so far already this loads window pop up screen but not saving them need help on this. But the saved fields must be able to view on this form. Help me on my current logic. I will share back end first code, followed by front end. 

// Store procedure for dynamic queries

//Managers class access the entities(uses store procedures these entities from the database)
  


public static DataTable GetRecipeIngredients(int recipeID, string productAllocation, int NoPremix)
        {
            Managers.BatchMaterialManager.SetAdriotConnection();
            return DataAccessProvider.GetDataTable(PremixBatch.PROC_NAME_GET, new object[] { "Calculate", null, null, recipeID, productAllocation, NoPremix });
        }
