protected editor prepaireditor(action<editor> oninit) { editor editor = new editor(system.web.httpcontext.current, "editor"); editor.clientfolder = "/richtexteditor/"; editor.contentcss = "/content/example.css"; //editor.clientfolder = "/content/richtexteditor/"; //editor.clientfolder = "/scripts/richtexteditor/"; editor.text = "type here"; editor.ajaxpostbackurl = url.action("editorajaxhandler"); if (oninit != null) oninit(editor); //try handle upload/ajax requests bool isajax = editor.mvcinit(); if (isajax) return editor; //load form data if if (this.request.httpmethod == "post") { string formdata = this.request.form[editor.name]; if (formdata != null) editor.loadformdata(formdata); } //render editor viewbag.editor viewbag.editor = editor.mvcgetstring(); return editor; } //this action specified editor.ajaxpostbackurl = url.action("editorajaxhandler"); //it handle editor dialogs upload/ajax requests [validateinput(false)] public actionresult editorajaxhandler() { prepaireditor(delegate(editor editor) { }); return new emptyresult(); } this screenshot of error occurring place in prepaireditor() method
