无法根据操作事件的销售订单更新销售报价屏幕中的自定义字段

Question

我在销售报价屏幕中创建了一个操作来创建销售订单。正在创建销售订单。如果创建了销售订单，我希望将创建的订单编号填充到销售报价屏幕的自定义字段中，并禁用操作按钮。虽然我在系统中没有收到任何错误。 当我刷新销售报价屏幕时，我得到了确切的结果，但不是在单击 Create SO Action 期间。

我不确定我哪里出错了。请参考下面的代码和图片：谢谢。 以下是我的代码：

  public class QuoteMaint_Extension : PXGraphExtension<QuoteMaint>
  {

        #region Event Handlers

        protected void CRQuote_RowSelected(PXCache cache, PXRowSelectedEventArgs e)
        {
            var row = (CRQuote)e.Row;
            CRQuoteExt quoteExt = PXCache<CRQuote>.GetExtension<CRQuoteExt>(row);

            if (quoteExt.UsrOrderNbr != null)
            {
                createSalesOrder.SetEnabled(false);
            }
            else
            {
                createSalesOrder.SetEnabled(true);

Answer 1

在定义 SOLine 键之前，从 transLine 对象获取 DAC 扩展。尝试在将transLine 插入数据视图后移动GetExtension 调用。

SOLine transline = new SOLine();
SOLineExt _soLext = PXCache<SOLine>.GetExtension<SOLineExt>(transline);

模式应该是这样的：

1. 创建空的 DAC 对象
2. 在数据视图中插入 DAC 对象
3. 获取 DAC 扩展并分配自定义字段
4. 在数据视图中更新 DAC 对象
