问题：警告 1 “System.Web.UI.Page.IsClientScriptBlockRegistered(string)”已过时:“The recommended alternative is ClientScript.IsClientScriptBlockRegistered(string key). http://go.microsoft.com/fwlink/?linkid=14202” H:\网站\JiChen\JiChen\Default.aspx.cs 19 18 JiChen


解决办法：
            ClientScriptManager CSM = Page.ClientScript;
            string ScriptName = "clientScript";
            if (!CSM.IsClientScriptBlockRegistered(ScriptName))
            {
                string strScript = "\n";
                CSM.RegisterStartupScript(this.GetType(), ScriptName, strScript);
            }

RegisterClientScriptBlock也一样

用ClientScriptManager代替,如:

  string   str   =   "SetColumnByCheckBox() ";
                        ClientScriptManager   cs   =   Page.ClientScript;
                        cs.RegisterStartupScript(this.GetType(),   " ",   str,   true);
