自定义网格空

Posted 2023-02-21

真的很简单但令人生气的问题。

1）创建了一个DB脚本，用于向数据库添加字段并发布。 2）根据改变的表创建一个新的DAC。 3）创建了一个新的屏幕和图形。 4）改变图形以指向＃2中创建的DAC。

问题：网格是空的，我无法让它显示任何东西。

通过从数据库加载生成的DAC（无更改）：

  [Serializable]
  public class INItemXRef : IBqlTable
  
    #region InventoryID
    [PXDBInt(IsKey = true)]
    [PXUIField(DisplayName = "Inventory ID")]
    public virtual int? InventoryID  get; set; 
    public abstract class inventoryID : IBqlField  
    #endregion

    #region SubItemID
    [PXDBInt(IsKey = true)]
    [PXUIField(DisplayName = "Sub Item ID")]
    public virtual int? SubItemID  get; set; 
    public abstract class subItemID : IBqlField  
    #endregion

    #region AlternateType
    [PXDBString(4, IsKey = true, InputMask = "")]
    [PXUIField(DisplayName = "Alternate Type")]
    public virtual string AlternateType  get; set; 
    public abstract class alternateType : IBqlField  
    #endregion

    #region BAccountID
    [PXDBInt(IsKey = true)]
    [PXUIField(DisplayName = "BAccount ID")]
    public virtual int? BAccountID  get; set; 
    public abstract class bAccountID : IBqlField  
    #endregion

    #region AlternateID
    [PXDBString(50, IsKey = true, IsUnicode = true, InputMask = "")]
    [PXUIField(DisplayName = "Alternate ID")]
    public virtual string AlternateID  get; set; 
    public abstract class alternateID : IBqlField  
    #endregion

    #region Descr
    [PXDBString(256, IsUnicode = true, InputMask = "")]
    [PXUIField(DisplayName = "Descr")]
    public virtual string Descr  get; set; 
    public abstract class descr : IBqlField  
    #endregion

    #region Uom
    [PXDBString(6, IsUnicode = true, InputMask = "")]
    [PXUIField(DisplayName = "Uom")]
    public virtual string Uom  get; set; 
    public abstract class uom : IBqlField  
    #endregion

    #region CreatedByID
    [PXDBCreatedByID()]
    public virtual Guid? CreatedByID  get; set; 
    public abstract class createdByID : IBqlField  
    #endregion

    #region CreatedByScreenID
    [PXDBCreatedByScreenID()]
    public virtual string CreatedByScreenID  get; set; 
    public abstract class createdByScreenID : IBqlField  
    #endregion

    #region CreatedDateTime
    [PXDBDate()]
    [PXUIField(DisplayName = "Created Date Time")]
    public virtual DateTime? CreatedDateTime  get; set; 
    public abstract class createdDateTime : IBqlField  
    #endregion

    #region LastModifiedByID
    [PXDBLastModifiedByID()]
    public virtual Guid? LastModifiedByID  get; set; 
    public abstract class lastModifiedByID : IBqlField  
    #endregion

    #region LastModifiedByScreenID
    [PXDBLastModifiedByScreenID()]
    public virtual string LastModifiedByScreenID  get; set; 
    public abstract class lastModifiedByScreenID : IBqlField  
    #endregion

    #region LastModifiedDateTime
    [PXDBDate()]
    [PXUIField(DisplayName = "Last Modified Date Time")]
    public virtual DateTime? LastModifiedDateTime  get; set; 
    public abstract class lastModifiedDateTime : IBqlField  
    #endregion

    #region Tstamp
    [PXDBTimestamp()]
    [PXUIField(DisplayName = "Tstamp")]
    public virtual byte[] Tstamp  get; set; 
    public abstract class tstamp : IBqlField  
    #endregion

    #region UsrNoteID
    [PXDBGuid()]
    [PXUIField(DisplayName = "Usr Note ID")]
    public virtual Guid? UsrNoteID  get; set; 
    public abstract class usrNoteID : IBqlField  
    #endregion

    #region UsrTemp
    [PXDBString(20, IsUnicode = true, InputMask = "")]
    [PXUIField(DisplayName = "Usr Temp")]
    public virtual string UsrTemp  get; set; 
    public abstract class usrTemp : IBqlField  
    #endregion

    #region Noteid
    [PXDBGuid()]
    [PXUIField(DisplayName = "Noteid")]
    public virtual Guid? Noteid  get; set; 
    public abstract class noteid : IBqlField  
    #endregion
  

屏幕图（仅改变视图以使用上面的DAC）：

using System;
using PX.Data;

namespace PennAirSales

  public class INItemXRefBLC : PXGraph<INItemXRefBLC>
  

    public PXSave<INItemXRef> Save;
    public PXCancel<INItemXRef> Cancel;


    public PXFilter<INItemXRef> MasterView;
    public PXFilter<INItemXRef> DetailsView;

    //[Serializable]
    //public class MasterTable : IBqlTable
    //

    //

    //[Serializable]
    //public class DetailsTable : IBqlTable
    //

    //
  

ASPX（无变化）

这是如此直截了当我无法理解为什么没有数据被拉（在一般查询中可以看到数据很好），看起来这是非常明显的我错过了...

答案

您需要一个不是过滤器的视图（PXSelect vs PXFilter）

尝试：

public PXSelect<INItemXRef> DetailsView;
