Ovveride Create Shipment logic

 @Kandy Beatty @Laura02 

I am trying to take quantity that package have and item that package have on shipment screen packages tab
But if i do in this way 
 

        public virtual void CreateShipment(CreateShipmentArgs args, CreateShipmentDelegate baseMethod)
        {
            baseMethod(args);

            var packages = Base.Packages.Select().FirstTableItems;

            foreach (var package in packages)
            {
                var test = package.InventoryID;
                var test1 = package.Qty;

}

inventoryID is null and Qty is 0.0. As i understood CreteShipment have this logic when it's calculating weight for package based on qty and item. How can i get this values? I goes throught CreateShipment method and have not found anything that could help me with that problem

Yes. For now i have this
 

public delegate void CreateShipmentDelegate(CreateShipmentArgs args);
        [PXOverride]
        public virtual void CreateShipment(CreateShipmentArgs args, CreateShipmentDelegate baseMethod)
        {
            baseMethod(args);

            var packages = Base.Packages.Select().FirstTableItems;

            foreach (var package in packages)
            {
                var salesOrder = (SOOrder)PXSelectJoin<SOOrder,
                            InnerJoin<SOLine, On<SOOrder.orderType, Equal<SOLine.orderType>,
                                                And<SOOrder.orderNbr, Equal<SOLine.orderNbr>>>>,
                            Where<SOLine.lineNbr, Equal<Required<SOLine.lineNbr>>>>
                            .Select(Base, package.LineNbr);

                if (salesOrder != null)
                {

                }

                /*SelectedPackageContents selectedPackageContents = new SelectedPackageContents
                {
                    ShipmentLineNbr = package.LineNbr,
                    ShipmentNbr = package.ShipmentNbr,
                    PackedQty = package.Qty,
                };

                SelectedPackageContentsView.Insert(selectedPackageContents);*/
            }
        }

When shipment creating i want to make something like this
 

But in upper grid i can not take Qty of items in package and also there is no InventoryID in package. The main problem not to take Qty for package

Yes. It is my custom grid
