Question

我扩展了SOOrderEntry图并添加了以下代码，以便更新与当前要更新的当前行相关的同一销售订单上的另一行：

protected virtual void SOLine_RowUpdating(PXCache cache, PXRowUpdatingEventArgs e)
{
    if (e.NewRow == null)
    {
        return;
    }

    SOLine soLine = (SOLine)e.NewRow;

    SOLine relatedLine = Base.Transactions.Search<SOLine.inventoryID> 
    (456);

    if (relatedLine != null)
    {
           relatedLine.Qty = soLine.Qty;
           relatedLine.CuryUnitPrice = 24.20;

           Base.Transactions.Update(relatedLine);
           Base.Transactions.View.RequestRefresh();
    }
}

当我尝试通过更新当前行上的数量进行测试时，相关行上的单价只会在我更新数量时每隔一次更新一次。相关物料是非库存物料，其中当前物料是库存物料。

我正在18.102.0048的Sales Demo环境中进行此操作

我尝试过此操作，但现在扩展价格始终为0.00：

protected virtual void SOLine_RowUpdating(PXCache cache, PXRowUpdatingEventArgs e)
{
    if (e.NewRow == null)
    {
        return;
    }

    SOLine soLine = (SOLine)e.NewRow;

    SOLine relatedLine = Base.Transactions.Search<SOLine.inventoryID> 
(456);

    if (relatedLine != null)
    {
       SOLine oldRelatedLine = PXCache<SOLine>.CreateCopy(relatedLine);
       relatedLine.Qty = soLine.Qty;
       relatedLine.CuryUnitPrice = 24.20;

       Base.Transactions.Cache.RaiseRowUpdated(relatedLine, oldRelatedLine);

       Base.Transactions.Update(relatedLine);
       Base.Transactions.View.RequestRefresh();
    }
}

Answer 1

当一个字段的计算值取决于另一个字段的值时，有时需要触发事件以重新计算该值。

在某些情况下，仅需要为您修改的字段触发事件。使用C＃赋值运算符（=）或SetValue方法分配值不会触发事件处理程序，SetValueExt方法将：

// Doesn't trigger events
relatedLine.Qty = soLine.Qty;
cache.SetValue<SOLine.qty>(relatedLine, soLine.Qty);

// This will trigger events
cache.SetValueExt<SOLine.qty>(relatedLine, soLine.Qty);

在某些情况下，您也需要为整个行触发事件。您可以使用RaiseXxxYyy方法执行此操作。我在示例中使用了Current，但如果Current不是要修改的行，则可能必须对其进行修改：

SOLine oldRowCopy = PXCache<SOLine>.CreateCopy(Base.Transactions.Current);
Base.Transactions.Current.Qty = soLine.Qty;
Base.Transactions.Cache.RaiseRowUpdated(Base.Transactions.Current, oldRowCopy);

编辑：

看着更新的问题，可能不会有太大的区别，但我建议您切换这两行的顺序：

   Base.Transactions.Cache.RaiseRowUpdated(relatedLine, oldRelatedLine);
   Base.Transactions.Update(relatedLine);

赞：

// You want the value in Cache to be updated
Base.Transactions.Update(relatedLine);

// After Cache value is set you want to raise the events
Base.Transactions.Cache.RaiseRowUpdated(relatedLine, oldRelatedLine);
