掌握/详细信息ASP.NET C＃DataGrid？

Question

我想用DataGrid而不是GridView或其他任何东西显示数据Master / Details stype。目前我必须手动输入一个下拉列表。那么每当我们点击Master DataGrid中的一个主项目然后它链接到Details DataGird时，如何自动完成它，如下所示：

    private void BindGridMaster()
    {
        grdReceivedNote.DataSource = ReceivedNoteService.ReceivedNote_GetByAll();
        grdReceivedNote.DataBind();
        if (grdReceivedNote.PageCount <= 1)
        {
            grdReceivedNote.PagerStyle.Visible = false;
        }
        else
        {
            grdReceivedNote.PagerStyle.Visible = true;
        }
    }
    private void BindGridDetails()
    {
        grdReceivedNoteDetails.DataSource = RevNoteDetailsService.RevNoteDetails_GetByAll();
        grdReceivedNoteDetails.DataBind();
        if (grdReceivedNoteDetails.PageCount <= 1)
        {
            grdReceivedNoteDetails.PagerStyle.Visible = false;
        }
        else
        {
            grdReceivedNoteDetails.PagerStyle.Visible = true;
        }
    }
    protected void grdReceivedNote_ItemDataBound(object sender, DataGridItemEventArgs e)
    {
        ListItemType itemType = e.Item.ItemType;
        if ((itemType != ListItemType.Footer) && (itemType != ListItemType.Separator))
        {
             if (itemType == ListItemType.Header)
             {
                 object checkBox = e.Item.FindControl("chkSelectAll");
                 if ((checkBox != null))
                 {
                      ((CheckBox)checkBox).Attributes.Add("onClick", "Javascript:chkSelectAll_OnClick(this)");
                 }
            }
            else
            {
                 string tableRowId = grdReceivedNote.ClientID + "_row" + e.Item.ItemIndex.ToString();
                 e.Item.Attributes.Add("id", tableRowId);
                 object checkBox = e.Item.FindControl("chkSelect");
                 if ((checkBox != null))
                 {
                      e.Item.Attributes.Add("onMouseMove", "Javascript:chkSelect_OnMouseMove(this)");
                      e.Item.Attributes.Add("onMouseOut", "Javascript:chkSelect_OnMouseOut(this," + e.Item.ItemIndex.ToString() + ")");
                      ((CheckBox)checkBox).Attributes.Add("onClick", "Javascript:chkSelect_OnClick(this," + e.Item.ItemIndex.ToString() + ")");
                  }
            }
       }
   }
   protected void grdReceivedNoteDetails_ItemDataBound(object sender, DataGridItemEventArgs e)
   {
       ListItemType itemType = e.Item.ItemType;
       if ((itemType != ListItemType.Footer) && (itemType != ListItemType.Separator))
       {
            if (itemType == ListItemType.Header)
            {
                object checkBox = e.Item.FindControl("chkSelectAll");
                if ((checkBox != null))
                {
                    ((CheckBox)checkBox).Attributes.Add("onClick", "Javascript:chkSelectAll_OnClick(this)");
                }
           }
           else
           {
                string tableRowId = grdReceivedNote.ClientID + "_row" + e.Item.ItemIndex.ToString();
                e.Item.Attributes.Add("id", tableRowId);
                object checkBox = e.Item.FindControl("chkSelect");

                }
           }
       }
  }
