Question

我有一张小桌子，只允许我输入一行。每当我尝试添加另一行时，我都会收到一条错误，指出另一个进程更改了数据。我已经做了很多其他更多涉及的自定义，但我只是想不出这个。那里的人有什么想法吗？

非常感谢！

您获得的错误很可能是由数据库级别的主键约束违规引起的。因为您从具有2个泛型类型参数的PXGraph类继承而来，这些参数具有预先定义的一系列操作，所以PXDataSource总是尝试在EDCompanyData中插入新行，而不是更新数据库中唯一的现有记录。我建议只使用1个泛型类型参数继承PXGraph类，并仅定义“保存”和“取消”操作：

public class EDCompanyMaint : PXGraph<EDCompanyMaint, EDCompanyData>
{
    public PXSave<EDCompanyData> Save;
    public PXCancel<EDCompanyData> Cancel;

    public PXSelect<EDCompanyData> EDCompany;
}
