Question

真正简单却令人生厌的问题。

1）创建一个DB脚本以将字段添加到数据库中并发布。 2）根据更改后的表创建一个新的DAC。 3）创建一个新的屏幕和图形。 4）更改图形以指向在＃2中创建的DAC。

问题：网格为空，我无法显示任何内容。

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（仅更改为使用上面的DAC的视图）：

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（无更改）

                <px:PXGridColumn DataField="AlternateType" Width="70" />

        <ActionBar >

    </px:PXGrid>
</asp:Content>

这太简单了，我无法理解为什么没有数据被提取（可以在通用查询中看到数据很好），似乎很明显我很想念...

Answer 1

您需要的视图不是过滤器（PXSelect与PXFilter）

尝试：

public PXSelect<INItemXRef> DetailsView;

自定义网格为空
