ArgumentOutOfRange指定单声道datagridview的数据源时出现异常

ArgumentOutOfRange在datagridview中分配数据源时发生异常。ArgumentOutOfRange指定单声道datagridview的数据源时出现异常

编辑：此代码工作正常，当我使用列表代替BindingList。

环境：单声道4.0.12。 C＃WinForm应用程序

代码：

public class DataGridViewStudyReference : CustomControls.DataGridViewDataEntry<StudyRefrenceValueBusinessObjectNew> 
{ 
} 

public class DataGridViewDataEntry<BindingSourceType> : DataGridView 
{ 
     public void ResetDataSource() 
     { 
      if (DataEntrySource == null) 
      { 
       DataEntrySource = new BindingList<BindingSourceType>(); 
       this.DataSource = DataEntrySource; 
      } 
      else 
      { 
       DataEntrySource.Clear(); 
      } 
     } 
} 

public class StudyRefrenceValueBusinessObjectNew 
{ 
    public long StudyReferenceID { get; set; } 

    public long StudyID { get; set; } 

    public int GenderValue { get; set; } 

    public int AgeInitial { get; set; } 

    public int AgeFinal { get; set; } 

    public string TextValue { get; set; } 

    public int ValueInitial { get; set; } 

    public int ValueFinal { get; set; } 

}

满异常详细信息是如下

消息：

索引小于0或大于或等于列表计数。参数名称：索引1

任何人可以帮助我，为什么这个异常发生的？

我得到了问题的原因。

在我的DataGridView AutoSizeColumnsMode模式设置为AllCell我改变它为None。然后删除此错误。单声道框架中的列大小计算似乎存在内部问题，我认为这是单声道框架的错误。但目前我的问题已解决。
