在 Acumatica 中按事件动态更改 PXSelector

Question

我在形成动态选择器时遇到了一些问题，下面我将想象一下已经完成了什么。 我需要根据所选 AssetId 动态生成选择器。 AssedInfo 选择器必须根据 AssetId 中选择的信息类型返回信息。我试过了，分步骤：

public class NSIAssetLinkInfo: IBqlTable
    {
        #region AssetId
        [PXDBString(500, IsUnicode = true, InputMask = "")]
        [PXUIField(DisplayName = "Asset Id")]
        [PXStringList(
            new string[]
            {
                "AssedInfo","GLTran"
            },
            new string[]
            {
                "AssedInfo","GLTran"
            })]
        public virtual string AssetId { get; set; }
        public new abstract class assetId : PX.Data.BQL.BqlString.Field<assetId> { }
        #endregion

        #region AssetInfo
        [PXUIField(DisplayName = "Asset Information")]
        [PXDBString(500, IsUnicode = true, InputMask = "")]
        public virtual string AssetInfo { get; set; }
        public abstract class assetInfo : PX.Data.BQL.BqlString.Field<assetInfo> { }
        #endregion
    }

在这里，我创建了一个按钮和一个应该动态形成我们的选择器的事件。 并且选择器将形成的事件还必须返回不是所有的列，而只返回必要的列，例如“AssetID - RecordType”，如果你是准确的，那么你只需要我将指出的那些列，而不是全部。 added button to panel

我正在努力遵循你的榜样与你所说的你需要做的事情。看起来您希望将 AssetID 中的允许值列表正确设置为预定义列表。如果您使用 RowSelected 事件并预定义您的允许列表，这将比您的示例简单得多。下面是一个非常精简的示例，显示了我如何使用 1 个示例列表完成此操作。您可以根据允许的组合定义多个列表，并根据您的条件为 listattr 指定所需的类型。

protected void _(Events.RowSelected<XXMyDAC> e)
{
    if(*condition*) // Substitute your conditional logic here
    {
        SelectableValues listattr = new SelectableValues();
        PXStringListAttribute.SetList<XXMyDAC.myField>
            (e.Cache, row, listattr.AllowedValues, listattr.AllowedLabels);
    }
}

public class SelectableValues : PXStringListAttribute
{

    public string[] AllowedLabels = new string[]
    {
            Messages.MyLabel1,
            Messages.MyLabel2
    };

    public string[] AllowedValues = new string[]
    {
            MyValue1,
            MyValue2
    };
}

如果您需要限制从数据库而不是从预定义列表返回的值，您可以直接在 DAC 中或通过图中的 CacheAttached 对 DAC 字段使用 PXRestrictorAttribute。这是一个非常简单的示例，它使用一个名为 UsrXXMyCondition 的自定义字段添加到 INLocation（通过 DAC 扩展 INLocationExt）。

[PXMergeAttributes(Method = MergeMethod.Append)]
[PXRestrictor(typeof(
    Where<INLocationExt.usrXXMyCondition, NotEqual<ConditionType.condition1>>
    ), "")]
protected virtual void INTran_ToLocationID_CacheAttached(PXCache sender) { }
