DevExpress: ASPxGridView 后台设定选中某一行

网上没有找到解决方案，试了N次，终于解决了。这里暂时提供2种方案:

// 选中某一行
        public static void FocusGridRowByKeyValue(DevExpress.Web.ASPxGridView.ASPxGridView grv, string sKeyFieldValue)
        {
            grv.SettingsBehavior.AllowFocusedRow = false;
            grv.SettingsBehavior.AllowFocusedRow = true;
            grv.FocusedRowIndex = -1;
            grv.Selection.SelectRow(grv.FindVisibleIndexByKeyValue(sKeyFieldValue));
            bool bBackToPage = grv.MakeRowVisible(sKeyFieldValue);// 可以定位回到某一页去
        }

        // 选中某一行
        public static void FocusGridRowByKeyValue(DevExpress.Web.ASPxGridView.ASPxGridView grv, string sKeyFieldName, string sKeyFieldValue)
        {
            object oValue = null;
            for (int i = 0; i < grv.VisibleRowCount; i++)
            {
                oValue = grv.GetRowValues(i, sKeyFieldName);
                if (oValue != null && oValue.ToString() == sKeyFieldValue)
                {
                    grv.SettingsBehavior.AllowFocusedRow = false;
                    grv.SettingsBehavior.AllowFocusedRow = true;
                    grv.FocusedRowIndex = -1;
                    grv.Selection.SelectRow(i);
                    bool bBackToPage = grv.MakeRowVisible(sKeyFieldValue);// 可以定位回到某一页去
                    break;
                }
            }
        }

调用例子：

          

if(Request.Params["id"] != null && Request.Params["id"].Trim() !="")          
           {               
                    FocusGridRowByKeyValue(grv_User, "UserID", Request.Params["id"].ToString());            
          }
 或
 
            if(Request.Params["id"] != null && Request.Params["id"].Trim() !="")          
            {               
                    FocusGridRowByKeyValue(grv_User,Request.Params["id"].ToString());           
             }
