Question

我必须根据配置屏幕中的字母设置在口罩中显示价格。

我正在尝试为DAC字段编写自定义属性，以便可以在报表中使用该属性。

我在下面给出了现有代码。函数调用工作正常，我正在使用它来获取价值，但是我无法将其用作DAC属性

#region PXPriceMaskAttribute
[AttributeUsage(AttributeTargets.Method | AttributeTargets.Property | AttributeTargets.Parameter | AttributeTargets.Class)]
public class PXPriceMaskAttribute : PXStringAttribute
{
    #region Ctor
    public PXPriceMaskAttribute()
         : base()
    {

    }
    #endregion
    #region Implementation
    /// <exclude/>
    /// 
    public static string GetPriceMask(PXGraph grp , decimal? val)
    {
        string _maskedstring = string.Empty;
        decimal value = val ?? 0m;
        int ivalue = Convert.ToInt32(Math.Floor(value));
        if (ivalue > 0)
        {
            MemoSetUp setUp = PXSelect<MemoSetUp>.Select(grp);
            char[] arr = ivalue.ToString().ToCharArray();
            char prevvalue = ' ';

            foreach (char cval in arr)
            {

上面的代码不起作用。解决此问题的最佳方法是什么。

更新

我创建了一个BQL评估器并附加到DAC，它始终返回零。

public class PriceRounding<PriceField> : BqlFormulaEvaluator<PriceField>, IBqlOperand
        where PriceField : IBqlField
    {
        public override object Evaluate(PXCache cache, object item,
                                        Dictionary<Type, object> pars)
        {
            PXFieldState fState = cache.GetStateExt<PriceField>(item) as PXFieldState;
            return GetSortOrderValueExt(Convert.ToDecimal(fState.Value));
        }

        public decimal GetSortOrderValueExt(decimal dVal)
        {
            dVal = Math.Round(dVal, 0);
            decimal divider = (dVal <= 5000) ? 25m : (dVal <= 10000) ? 50m : (dVal <= 100000) ? 100m : 500m;
            decimal reminder = dVal % divider;
            if (reminder > 0)
            {
                decimal diff = divider - reminder;
                dVal = dVal + diff;
            }
            return dVal;
        }
    }

DAC字段

#region RetailPrice
        public abstract class retailPrice : PX.Data.IBqlField
        {
        }
        protected decimal? _RetailPrice;
        [PXDBDecimal(2)]
        [PXUIField(DisplayName = "Retail Price")]
        [PXFormula(typeof(PriceRounding<InfoInventoryItemAttributeExtNV.retailPrice>))]
        public virtual decimal? RetailPrice
        {
            get
            {
                return this._RetailPrice;
            }
            set
            {
                this._RetailPrice = value;
            }
        }
        #endregion

Answer 1

考虑使用自定义BQL函数（源自BqlFormulaEvaluator）–您可以引用PX.Objects源代码的公式子文件夹中提供的现成的自定义BQL函数。或者，您可以参考KB article，其中使用了此类自定义BQL函数HierarchySorting。

Answer 2

与使用BQL公式评估程序相比，以下代码对我来说自定义四舍五入效果很好

.datepicker({...})

在DAC中使用

$(...).datepicker is not a function

创建自定义属性
