Matrix Item Grid (Table View) Notes

Trying a different approach.  Rather than trying to use the built in note feature on the matrix grid I’ve added a UsrNote to MatrixInventoryItemExt.  When SO lines are added during Add & Close I can use this to create a regular PXNote on SOLine.  However, I can’t figure out how to override or hook the AddItemsToOrder method.

// Get note
string note = PXNoteAttribute.GetNote([Matrix cache], [Matrix record]);

// Set note
PXNoteAttribute.SetNote([SOLine cache], [SOLine record], note);

Hi Zoltan,

I tried this but had no luck:

 [PXProtectedAccess]
 public abstract class SmartPanelExt_ProtectedExtension : MatrixEntryExt
 {
     [PXProtectedAccess(typeof(SmartPanelExt<SOOrderEntry, SOOrder>))]
     protected override CreateMatrixItemsHelper GetCreateMatrixItemsHelper(PXGraph graph)
     {
         return new CreateMatrixItemsHelperExt(graph);
     }

     [PXProtectedAccess(typeof(SmartPanelExt<SOOrderEntry, SOOrder>))]
     protected override void AddMatrixItemsToOrder(int? siteID) 
     { 
// I had a breakpoint set here but it was never hit after Add & Close clicked
         base.AddMatrixItemsToOrder(siteID);

         foreach (MatrixInventoryItem item in base.MatrixItems.Cache.Cached)
         {
             if (item.InventoryID == null || item.InventoryID == 0) continue;

             SOLine soOrderLine = base.Base.Transactions
                 .Select(Base, item.InventoryID, siteID);

             if (soOrderLine != null)
             {
                 MatrixMatrixInventoryItemExt ext = item.GetExtension<MatrixMatrixInventoryItemExt>();
                 if (ext != null && !string.IsNullOrEmpty(ext.UsrNote))
                 {
                     PXNoteAttribute.SetNote(Base.Transactions.Cache, soOrderLine, ext.UsrNote);
                 }
             }
         }
     }
 }

Here is my solution.  Seems to be working:

    [PXProtectedAccess]
    public abstract class SmartPanelExt_ProtectedExtension : MatrixEntryExt
    {
        [PXProtectedAccess(typeof(SmartPanelExt<SOOrderEntry, SOOrder>))]
        protected override CreateMatrixItemsHelper GetCreateMatrixItemsHelper(PXGraph graph)
        {
            return new CreateMatrixItemsHelperExt(graph);
        }

        [PXProtectedAccess(typeof(SmartPanelExt<SOOrderEntry, SOOrder>))]
        protected override void CreateNewLine(int? siteID, int? inventoryID, string taxCategoryID, decimal qty, string uom) 
        { 
            // PXTrace.WriteInformation("HIT CreateNewLine");
            base.CreateNewLine(siteID, inventoryID, taxCategoryID, qty, uom);

            SOLine soOrderLine = (SOLine)base.Base.Transactions.Cache.Current;

            if (soOrderLine != null)
            {
                MatrixInventoryItem item = base.MatrixItems.Cache.Cached.Cast<MatrixInventoryItem>().FirstOrDefault(x => x.InventoryID == soOrderLine.InventoryID);
                if (item != null)
                {
                    MatrixMatrixInventoryItemExt ext = item?.GetExtension<MatrixMatrixInventoryItemExt>();
                    if (ext != null && !string.IsNullOrEmpty(ext.UsrNote))
                    {
                        PXNoteAttribute.SetNote(Base.Transactions.Cache, soOrderLine, ext.UsrNote);
                    }
                }
            }
        }

    }

Update: after getting it to work with a custom note field I decided to try getting the built-in note from the matrix cache like ​@Zoltan Febert suggested and it works that way, too!

        [PXProtectedAccess(typeof(SmartPanelExt<SOOrderEntry, SOOrder>))]
        protected override void CreateNewLine(int? siteID, int? inventoryID, string taxCategoryID, decimal qty, string uom) 
        { 
            // PXTrace.WriteInformation("HIT CreateNewLine");
            base.CreateNewLine(siteID, inventoryID, taxCategoryID, qty, uom);

            SOLine soOrderLine = (SOLine)base.Base.Transactions.Cache.Current;

            if (soOrderLine != null)
            {
                MatrixInventoryItem item = base.MatrixItems.Cache.Cached.Cast<MatrixInventoryItem>().FirstOrDefault(x => x.InventoryID == soOrderLine.InventoryID);
                if (item != null)
                {
                    // MatrixMatrixInventoryItemExt ext = item?.GetExtension<MatrixMatrixInventoryItemExt>();
                    //if (ext != null && !string.IsNullOrEmpty(ext.UsrNote))
                    //{
                    //    PXNoteAttribute.SetNote(Base.Transactions.Cache, soOrderLine, ext.UsrNote);
                    //}

                    // Get built-in PXNote
                    string note = PXNoteAttribute.GetNote(base.MatrixItems.Cache, item);
                    if (!string.IsNullOrEmpty(note))
                    {
                        PXNoteAttribute.SetNote(Base.Transactions.Cache, soOrderLine, note);
                    }
                }
            }
        }
