如何在 fieldupdate 上設置值

Question

您好，我的自定義項目仍有問題，我正在使用 acumatica，我需要在 pxselect 或字段更新上獲取相應的字段，您能告訴我一種方法嗎？我已經嘗試了我在這里學到的所有內容。

所以這是我創建的代碼

 public class APTranExt : PXCacheExtension<PX.Objects.AP.APTran>
        {
            #region UsrWholdingATC
            [PXDBString(10)]
            [PXUIField(DisplayName = "WholdingATC")]
            [PXSelector(
            typeof(Search<withholdingtaxx.atc>),
                typeof(withholdingtaxx.taxRate))]
            public virtual string UsrWholdingATC { get; set; }
            public abstract class usrWholdingATC : PX.Data.BQL.BqlString.Field<usrWholdingATC> { }
            #endregion

            #region UsrWholdingrate
            [PXDBDecimal]
            [PXUIField(DisplayName = "Wholdingrate")]

            public virtual Decimal? UsrWholdingrate { get; set; }
            public abstract class usrWholdingrate : PX.Data.BQL.BqlDecimal.Field<usrWholdingrate> { }
            #endregion

            #region UsrWholdingamount
            [PXDBDecimal]
            [PXUIField(DisplayName = "WholdingAmount")]

            public virtual Decimal? UsrWholdingamount { get; set; }
            public abstract class usrWholdingamount : PX.Data.BQL.BqlDecimal.Field<usrWholdingamount> { }
            #endregion
            [Serializable]
        public class withholdingtaxx : IBqlTable
        {
            #region IDNbr
            [PXDBInt(IsKey = true)]
            [PXUIField(DisplayName = "IDNbr")]
            public virtual int? IDNbr { get; set; }
            public abstract class idNbr : PX.Data.BQL.BqlInt.Field<idNbr> { }
            #endregion

            #region Atc
            [PXDBString(50, IsUnicode = true, InputMask = "")]
            [PXUIField(DisplayName = "Atc")]
            public virtual string Atc { get; set; }
            public abstract class atc : PX.Data.BQL.BqlString.Field<atc> { }
            #endregion

            #region Type
            [PXDBString(50, IsUnicode = true, InputMask = "")]
            [PXUIField(DisplayName = "Type")]
            public virtual string Type { get; set; }
            public abstract class type : PX.Data.BQL.BqlString.Field<type> { }
            #endregion

            #region Description
            [PXDBString(400, IsUnicode = true, InputMask = "")]
            [PXUIField(DisplayName = "Description")]
            public virtual string Description { get; set; }
            public abstract class description : PX.Data.BQL.BqlString.Field<description> { }
            #endregion

            #region TaxRate
            [PXDBString(50, IsUnicode = true, InputMask = "")]
            [PXUIField(DisplayName = "Tax Rate")]
            public virtual string TaxRate { get; set; }
            public abstract class taxRate : PX.Data.BQL.BqlString.Field<taxRate> { }
            #endregion

            #region Bir_form
            [PXDBString(50, IsUnicode = true, InputMask = "")]
            [PXUIField(DisplayName = "Bir_form")]
            public virtual string Bir_form { get; set; }
            public abstract class bir_form : PX.Data.BQL.BqlString.Field<bir_form> { }
            #endregion
        }
        }

一切從這里工作得很好我成功地創建了一個自定義表來自 pxselector 的顯示表

所以我需要的是當我選擇 atc 值時，我還需要提取稅率並將其放在 wholdingrate 字段中，謝謝您的幫助

順便說一下，我試圖在這里放一些代碼，但是當我在調試模式下運行時它沒有命中 fieldupdate

protected void APTran_UsrWholdingATC_FieldUpdated(PXCache cache, PXFieldUpdatedEventArgs e)
    {

      var row = (APTran)e.Row;

    }

當我在調試模式下運行時，它不會命中 fieldupdate

通常發生這種情況是因為字段編輯器控件沒有將CommitChanges屬性設置為True ：

當CommitChanges在編輯器控件上設置為True時，當用戶更改值后控件失去焦點時，將調用FieldUpdated事件：

protected void APTran_UsrWholdingATC_FieldUpdated(PXCache cache, PXFieldUpdatedEventArgs e)
{
  APTran tran = e.Row as APTran;

  if (tran != null)
  {
    APTranExt tranExt = tran.GetExtension<APTranExt>();

    if (tranExt != null)
    {
       decimal? value = [...];
       cache.SetValue<APTranExt.usrWholdingrate>(tran, value);
    }
  }
}
