用到ScriptManager的頁面後台使用彈出對話方塊

Sys.WebForms.PageRequestManagerErrorException:The message received from the server could not be parsed錯誤解決方案

因為用的是Ajax的  ScriptManager +　UpdatePanel控制項

所以調用Response.Write(),Page.RegisterStartScript()等方法，就不行了

需要調用Ajax本身的ScriptManager.RegisterStartupScript（）方法；

具體格式為：

System.Web.UI.ScriptManager.RegisterStartupScript（Control control, Type type, string key,string script, bool addScriptTags）

調用方式為：

System.Web.UI.ScriptManager.RegisterStartupScript（this,this.GetType(),"KEY","alert('ss')",true);

 

現在項目中用到的列出幾個，以後可能用到的：

方法的調用：

AjaxFunc.ResponseWrite(this, this.GetType(), "alert('請登入後再使用該系統！');parent.document.location.href('../default.aspx');", true);

JS解釋：

alert('請登入後再使用該系統！');彈出訊息框

parent.document.location.href('../default.aspx');開啟指定頁

 

AjaxFunc.MessageBox(this, "Error", "輸入舊密碼不可為空！");

JS解釋：彈出訊息框

 

AjaxFunc.OpenModelUrl_EX(this.Page, "", "ShowCurveLine.aspx", 840, 550);

JS解釋：開啟模式頁面

 

AjaxFunc.OpenModelUrl_EX(this.Page, "", "ShowCurveLine.aspx", 840, 550);

JS解釋：開啟非模式頁面
