Modal Popup Extender中的Gridview - 回发问题？

Question

我在一个Ajax模式弹出窗口（VS2008）中有一个带gridview的C＃.Net应用程序。我有网格视图设置为每页返回10个记录启用分页。

当用户单击以在gridview中更改页面时，会有一个回传关闭模式窗口，然后使用ModalPopup.show（）重新打开它。

有什么办法可以避免整个页面的回发，只需回发gridview，同时保持模态窗口活动？目前，整个页面的回传让闪烁的印象...

而后面的代码...

public void Page_Load(object sender, EventArgs e) 
{ 

    try 
    { 
     if (!(Page.IsPostBack)) 
     { 
      GridView1.EnableViewState = true;

      GridView1.PageSize = 10; 
      GridView1.PagerSettings.Mode = PagerButtons.Numeric; 
      GridView1.Visible = true;    

     } 

     if (!m_bDisclaimerShown) 
     { 
      m_bDisclaimerShown = true; 
      mpe1.Show(); 
      TabContainer.Visible = true; 
      ScaleBar1.Visible = true; 


     } 
    } 
    catch (Exception ex) 
    { 
     ShowMsg("Error - " + ex.Message); 
    } 

}

      string strPostcode = txtPostCode.Text; 
      strPostcode = strPostcode.Substring(0, 4) + strPostcode.Substring(strPostcode.Length - 3, 3);

      SqlDataAdapter sqlAdapter = new SqlDataAdapter(sqlCmd);

      ModalPopupExtender1.Show(); 

     } 

     else

    } 
    finally 
    { 
     CloseDB(); 
    } 

}

     GridView1.DataSource = m_sqlDataTable; 
     GridView1.DataBind(); 
     ModalPopupExtender1.Show(); 

    } 
} 

protected void GridView1_SelectedIndexChanged(object sender, EventArgs e) 
{ 
    GridViewRow GVRow = GridView1.SelectedRow; 
    int iX = (int)Convert.ToSingle(GVRow.Cells[1].Text); 
    int iY = (int)Convert.ToSingle(GVRow.Cells[2].Text); 
    GridView1.Visible = false; 

    MoveMap(iX, iY); 
} 

public void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) 
{ 
    if (e.Row.DataItemIndex >= 0) 
    { 
     e.Row.Attributes["style"] = "cursor:pointer"; 
     e.Row.Attributes.Add("onMouseOver", "this.style.cursor='hand';"); 
     e.Row.Attributes.Add("onclick", ClientScript.GetPostBackEventReference(GridView1, "Select$" + e.Row.RowIndex.ToString())); 
    } 

} 

protected override void Render(HtmlTextWriter writer) 
{ 

    foreach (GridViewRow r in GridView1.Rows) 
    { 
     if (r.RowType == DataControlRowType.DataRow) 
     { 
      Page.ClientScript.RegisterForEventValidation(GridView1.UniqueID, "Select$" + r.RowIndex); 
     } 
    } 

    base.Render(writer); 
}

感谢您的建议。我已经把GridView的成...

<asp:UpdatePanel> 
<ContentTemplate> 

然而，现在模态停留，当我在网格中单击一个记录查看它不会关闭！
