protected void upload(object sender, ajaxcontroltoolkit.ajaxfileuploadeventargs e) { string s = dropdownlist1.selectedvalue; string t = dropdownlist2.selectedvalue; string path= string path = server.mappath("~/mca/" + s + "/" +t+ "/")+e.filename } //both s , t first value of dropdownlist if other value selected , that's uploading not done per directort structure.
both dropdownlist have several values , postback property true both list.
how exact selected value of list ?
issue request.form["__viewstate"] = null when ajaxfileupload onuploadcomplete event called.
fix issue (c# code):
set dropdown selection in session @ page load.
protected void page_load(object sender, eventargs e) { if (request.form["__viewstate"] != null) session["path"] = "//" + dropdownlist1.selectedvalue + "//" + dropdownlist2.selectedvalue + "//"; } use session value creation of filepath:
protected void upload(object sender, ajaxcontroltoolkit.ajaxfileuploadeventargs e) { string path = string.empty; if (session["path"] != null) path = server.mappath("~//mca" + (string)session["path"]) + e.filename; }
