写的GridView更新的方法，代码如下：
 protected void GridView1_OnUpDateCommand(object sender,  
 GridViewUpdatedEventArgs e)
    {
        string pk = GridView1.DataKeys[e.RowIndex]["ID"].Value.
                    ToString();//获取主键
        GridViewRow gvr = GridView1.Rows[e.RowIndex];

        string strName = ((TextBox)gvr.FindControl("textName")).Text;
        string strSex = ((TextBox)gvr.FindControl("textSex")).Text;
        string strBrithday = ((TextBox)gvr.FindControl
                             ("textBrithday")).Text;
        string strQQ = ((TextBox)gvr.FindControl("textQQ")).Text;

        try
        {
            objMenBer.UpDate(pk, strName, strSex, strBrithday, strQQ);
            this.Alter("记录更新成功！");
            Data_Bind();

        }
        catch (Exception ex)
        {
            this.Alter(ex.Message);
        }
    }
为何老是提示错误：
1、“System.Web.UI.WebControls.GridViewUpdatedEventArgs”并不包含“RowIndex”。
2、“GridView1_OnUpDateCommand”的重载均与委托“System.Web.UI.WebControls.GridViewUpdateEventHandler”不匹配    
高手们，这是怎么回事呢？困扰好几天了。

谢谢各位了。哈哈！
