从另一个绑定的自定义字段填充未绑定的字段

提问于

我要求在SalesOrder屏幕上有一个字段，并且相同的字段也应出现在Shipment屏幕上，也用于相应的SalesOrder . 并且用户应该能够在屏幕上更新这些字段 .

我在“销售订单”屏幕上创建了一个绑定字段，用户可以将其保存 . 然后我在“货件”屏幕上创建了一个未绑定的字段，以显示“销售订单”中的文本 . 为此，我编写了一个SOShipment_RowSelected事件，稍后用户将其更新到数据库，我写了SOShipment_RowUpdated . 但是，当我尝试编辑该字段时，它会触发RowSelected事件并覆盖编辑并返回相同的原始值 .

我尝试过使用SOShipment_ShipmentNbr_FieldUpdated和SOShipment_ShipmentNbr_FieldUpdating事件，但每次都没有触发 .

这是缓存扩展的代码 -

public class SOOrderExtension : PXCacheExtension<SOOrder>
{
	#region UsrNotesText
	[PXDBString(255)]
	[PXUIField(DisplayName = "Pick List Notes")]
	public virtual string UsrNotesText { get; set; }
	public abstract class usrNotesText : IBqlField { }
	#endregion
}
	
public class SOShipmentExtension : PXCacheExtension<SOShipment>
{
	#region UsrNotesText
	[PXString(255)]
	[PXUIField(DisplayName = "Pick List Notes")]
	public virtual string UsrNotesText { get; set; }
	public abstract class usrNotesText : IBqlField { }
	#endregion
}

SOShipmentExtension代码 -

public class SOShipmentEntryExtension : PXGraphExtension<SOShipmentEntry>
{
	PXSelect<SOOrder> soOrder;

	protected virtual void SOShipment_RowSelected(PXCache sender, PXRowSelectedEventArgs e)
	{
		if (e.Row != null)
		{
			SOOrder order = PXSelectJoin<SOOrder,
				LeftJoin<SOOrderShipment, On<SOOrder.orderNbr, Equal<SOOrderShipment.orderNbr>,
					And<SOOrder.orderType, Equal<SOOrderShipment.orderType>>>,
				LeftJoin<SOShipment, On<SOOrderShipment.shipmentNbr, Equal<SOShipment.shipmentNbr>>>>,
				Where<SOShipment.shipmentNbr, Equal<Current<SOShipment.shipmentNbr>>>>.Select(Base);

			if (order != null)
			{
				SOOrderExtension orderExt = PXCache<SOOrder>.GetExtension<SOOrderExtension>(order);

				SOShipment soShipment = Base.Document.Current;

				SOShipmentExtension ext = PXCache<SOShipment>.GetExtension<SOShipmentExtension>(soShipment);
				ext.UsrNotesText = orderExt.UsrNotesText;
			}
		}
	}

	protected virtual void SOShipment_RowUpdated(PXCache sender, PXRowUpdatedEventArgs e)
	{
		SOShipment oldRow = (SOShipment)e.OldRow;
		SOShipment newRow = (SOShipment)e.Row;

		if (oldRow != null || newRow != null)
		{
			SOShipmentExtension oldExt = PXCache<SOShipment>.GetExtension<SOShipmentExtension>(oldRow);
			SOShipmentExtension newExt = PXCache<SOShipment>.GetExtension<SOShipmentExtension>(newRow);


			if (oldExt.UsrNotesText != newExt.UsrNotesText)
			{
				{
					SOOrder order = PXSelectJoin<SOOrder,
					LeftJoin<SOOrderShipment, On<SOOrder.orderNbr, Equal<SOOrderShipment.orderNbr>,
						And<SOOrder.orderType, Equal<SOOrderShipment.orderType>>>,
					LeftJoin<SOShipment, On<SOOrderShipment.shipmentNbr, Equal<SOShipment.shipmentNbr>>>>,
					Where<SOShipment.shipmentNbr, Equal<Current<SOShipment.shipmentNbr>>>>.Select(Base);

					soOrder.Current = order;

					if (order != null)
					{
						SOOrderExtension orderExt = PXCache<SOOrder>.GetExtension<SOOrderExtension>(order);

						orderExt.UsrNotesText = newExt.UsrNotesText;
						soOrder.Update(order);
					}
				}
			}
		}
	}
}

有什么建议？

    诀窍是在别处初始化UsrNotesText .

    您可以使用PXDefault属性：

    [PXDefault(typeof(Search<SOOrderExtension.usrNotesText, Where< [...] >>))]

    或FieldDefaulting事件处理程序：

    public void SOShipment_UsrNotesText_FieldDefaulting(PXCache sender, PXFieldDefaultingEventArgs e)
{
   e.NewValue = [...]
}

    有时您还希望在用户更改未重新触发默认值的关键字段时重新初始化：

    public void SOShipment_ShipmentNbr_FieldUpdated(PXCache sender, PXFieldDefaultingEventArgs e)
{
    SOShipment shipment = e.Row as SOShipment;

    if (shipment != null)
    {
        SOShipmentExtension shipmentExt = PXCache<SOShipment>.GetExtension<SOShipmentExtension>(shipment);

        if (shipmentExt != null)
        {
            shipmentExt.UsrNotesText = [...];
        }
    }
}

    在这种情况下，使用RaiseFieldDefaulting手动重新触发FieldDefaulting事件通常是更好的选择 .

    但是，您选择初始化的方法避免在RowSelected中设置字段值，因为有时在您不想初始化自定义字段时调用该事件 .
