Question

我正在为员工时间活动屏幕（EP307000）制作表单模型。我正在构建一个额外的网格来显示给定月份的所有数据。为此，我需要一个允许用户选择月/年组合的字段。我已经构建了自定义PXSelector并获取了所有数据来填充它，但我遇到的问题是每当焦点转移到该字段时，描述字段都被隐藏，并且只显示自然键。例如，如果用户选择2017年6月，则该字段中存储的值应为“20170630”，但显示给用户的值应为“2017年6月”。

“From Week”和“Until Week”PXSelector字段具有我想要的功能，但我似乎无法复制它。这就是宣布“直到周”的方式：

#region TillWeek
public abstract class tillWeek : IBqlField
{
}
[PXDBInt]
[PXWeekSelector2(DescriptionField = typeof(EPWeekRaw.shortDescription))]
[PXUIField(DisplayName = "Until Week", Visibility = PXUIVisibility.Visible)]
public virtual int? TillWeek { set; get; }
#endregion

下面的图片显示了字段之间的差异。 “From Week”字段看起来不同，因为我从PXWeekSelector2中删除了“DescriptionField = typeof（EPWeekRaw.shortDescription）”。

这是自定义选择器的代码：

public class MonthYearSelectorAttribute : PXCustomSelectorAttribute
{

    public MonthYearSelectorAttribute()
        : base(typeof(DateInfoExt.dateInt), new Type[]{ typeof (DateInfoExt.monthName), typeof (DateInfoExt.year)})
    {
        DescriptionField = typeof(DateInfoExt.description);
    }

    public override void FieldVerifying(PXCache sender, PXFieldVerifyingEventArgs e)
    {
    }

    protected virtual IEnumerable GetRecords()
    {
        DateTime currentDate = DateTime.Now;
        PX.SM.DateInfo dateInfo = PXSelect<PX.SM.DateInfo, Where<PX.SM.DateInfo.month, Equal<Required<PX.SM.DateInfo.month>>, And<PX.SM.DateInfo.year, Equal<Required<PX.SM.DateInfo.year>>>>>.Select(this._Graph, currentDate.Month, currentDate.Year);
        int? currentDateInt = dateInfo.DateInt;
        int? pastDateInt = dateInfo.DateInt - 50000;

        foreach(PX.SM.DateInfo result in PXSelectGroupBy<PX.SM.DateInfo, Where<PX.SM.DateInfo.dateInt, LessEqual<Required<PX.SM.DateInfo.year>>, And<PX.SM.DateInfo.dateInt, GreaterEqual<Required<PX.SM.DateInfo.dateInt>>>>, Aggregate<GroupBy<PX.SM.DateInfo.month, GroupBy<PX.SM.DateInfo.year>>>, OrderBy<Asc<PX.SM.DateInfo.year, Asc<PX.SM.DateInfo.month>>>>.Select(this._Graph, currentDateInt, pastDateInt))
        {
            DateInfoExt ext = new DateInfoExt();
            ext.Year = result.Year;
            ext.MonthName = result.MonthName;
            ext.DateInt = result.DateInt;
            ext.Description = result.MonthName + "-" + result.Year.ToString();
            yield return ext;
        }
    }
}
public class DateInfoExt : IBqlTable
{
    public DateInfoExt()
    {
    }
    [PXString]
    [PXUIField(DisplayName = "Description")]
    public virtual string Description { get; set; }
    public abstract class description : IBqlField
    {
    }
    [PXDBString]
    [PXUIField(DisplayName = "MonthYear", IsReadOnly = true)]
    public virtual string MonthYear { get; set; }
    public abstract class monthYear : IBqlField
    {
    }
    [PXDBString]
    [PXUIField(DisplayName = "Month Name", IsReadOnly = true)]
    public virtual string MonthName { get; set; }
    public abstract class monthName : IBqlField
    {
    }
    [PXDBInt]
    [PXUIField(DisplayName = "Year", IsReadOnly = true)]
    public virtual int? Year { get; set; }
    public abstract class year : IBqlField
    {
    }
    [PXDBInt(IsKey = true)]
    [PXUIField(DisplayName = "Date (Integer)", IsReadOnly = true, Visible = false)]
    public virtual int? DateInt { get; set; }
    public abstract class dateInt : IBqlField
    {
    }
}
public class PMTimeActivityFilterExt : PXCacheExtension<PX.Objects.EP.EmployeeActivitiesEntry.PMTimeActivityFilter>
{

    public abstract class month : IBqlField
    {
    }
    [PXDBInt]
    [MonthYearSelector]
    [PXUIField(DisplayName = "Month", Visibility = PXUIVisibility.Visible)]
    public virtual int Month
    {
        get; set;
    }
}

提前致谢

尝试＃1 ：这可能是您在PXSelector控件上设置为文本的 DisplayMode 属性ASPX？

<px:PXSelector runat="server" DataField="Month" ID="edMonth" ... DisplayMode="Text"/>

尝试＃2：以下是框架支持的唯一可实现的结果 - Year-Month 组合，后跟 MonthName Year 描述在括号内：

将无法显示Month选择器内的一个字段的值，并通过其他字段在下拉网格中排序记录 - 框架根本不支持此类行为。

要获得上述结果，您应将DateInfoExt描述字段中使用的PXUIFieldAttribute的Visible设置为false：

public class DateInfoExt : IBqlTable
{
    ...
    public abstract class description : IBqlField { }
    [PXString()]
    [PXUIField(DisplayName = "Description", Visible = false)]
    public virtual string Description { get; set; }
    ...

}

稍微改变DateInfoExt DAC的Description字段如何填充delagate中的值：

foreach (PX.SM.DateInfo result in PXSelectGroupBy<PX.SM.DateInfo, 
    Where<PX.SM.DateInfo.dateInt, LessEqual<Required<PX.SM.DateInfo.year>>, 
        And<PX.SM.DateInfo.dateInt, GreaterEqual<Required<PX.SM.DateInfo.dateInt>>>>, 
    Aggregate<GroupBy<PX.SM.DateInfo.month, GroupBy<PX.SM.DateInfo.year>>>, 
    OrderBy<Asc<PX.SM.DateInfo.year, Asc<PX.SM.DateInfo.month>>>>.Select(this._Graph, currentDateInt, pastDateInt))
{
    DateInfoExt ext = new DateInfoExt();
    ext.DateInt = result.DateInt;
    ext.Year = result.Year;
    ext.MonthName = result.MonthName;
    ext.Description = string.Format("{0}-{1} ({2} {0})", result.Year, result.Month, result.MonthName);
    yield return ext;
}

这就是我在Aspx中声明 Month 选择器的方式：

<px:PXSelector runat="server" DataField="Month" ID="edMonth" CommitChanges="True" TextMode="Search" ValueField="DateInt" DisplayMode="Text"/>

是否可以仅在自定义PXSelector中显示DescriptionField？
