here make upload file dose not work update panel

public void buttonsend_click(object sender, system.eventargs e) {     uploadedfilelog.innerhtml = "";      if (radupload1.uploadedfiles.count > 0)     {         foreach (telerik.web.ui.uploadedfile postedfile in radupload1.uploadedfiles)         {             uploadedfilelog.innerhtml += "<b>uploaded file information</b>: <hr />";             uploadedfilelog.innerhtml += "<b>nick name</b>: " + nicktextbox.text;              if (!object.equals(postedfile, null))             {                 string filname = postedfile.filename;                 string tim = datetime.now.second.tostring() + "-" + datetime.now.minute.tostring() + "-" + datetime.now.hour.tostring() + "-" + datetime.now.day.tostring() + "-" + datetime.now.month.tostring() + "-" + datetime.now.year.tostring();                 postedfile.saveas(server.mappath("~/files/test/") + tim + "#" + filname);                 if (postedfile.contentlength > 0)                 {                     uploadedfilelog.innerhtml += string.format("<br /><b>filename</b>: {0}", postedfile.filename);                     uploadedfilelog.innerhtml += string.format("<br /><b>file size</b>: {0} bytes", postedfile.contentlength);                 }                 else                 {                     uploadedfilelog.innerhtml += "<br />no uploaded files yet.";                 }             }             else             {                 uploadedfilelog.innerhtml += "<br />no uploaded files yet.";             }         }     }   }  protected void save_click(object sender, eventargs e) {     uploadedfilelog.innerhtml = "";     uploadedfilelog.innerhtml += radupload1.uploadedfiles.count.tostring();     if (radupload1.uploadedfiles.count > 0)     {          foreach (telerik.web.ui.uploadedfile postedfile in radupload1.uploadedfiles)         {             uploadedfilelog.innerhtml += "<b>uploaded file information</b>: <hr />";             uploadedfilelog.innerhtml += "<b>nick name</b>: " + nicktextbox.text;              if (!object.equals(postedfile, null))             {                 string filname = postedfile.filename;                 string tim = datetime.now.second.tostring() + "-" + datetime.now.minute.tostring() + "-" + datetime.now.hour.tostring() + "-" + datetime.now.day.tostring() + "-" + datetime.now.month.tostring() + "-" + datetime.now.year.tostring();                 postedfile.saveas(server.mappath("~/files/test/") + tim + "#" + filname);                 if (postedfile.contentlength > 0)                 {                     uploadedfilelog.innerhtml += string.format("<br /><b>filename</b>: {0}", postedfile.filename);                     uploadedfilelog.innerhtml += string.format("<br /><b>file size</b>: {0} bytes", postedfile.contentlength);                 }                 else                 {                     uploadedfilelog.innerhtml += "<br />no uploaded files yet.";                 }             }             else             {                 uploadedfilelog.innerhtml += "<br />no uploaded files yet.";             }         }     } }

uploading files requires full postback.

also, try using radasyncupload, radupload has been obsolete 2 years now.

you can read on both things here http://www.telerik.com/help/aspnet-ajax/asyncupload-overview.html

here example:

        <asp:updatepanel id="updatepanel1" runat="server">             <contenttemplate>                 <telerik:radasyncupload runat="server" id="radasyncupload1"></telerik:radasyncupload>                 <asp:button id="button1" text="work files" onclick="button1_click" runat="server" />             </contenttemplate>         </asp:updatepanel>

and

protected void button1_click(object sender, eventargs e) {     foreach (uploadedfile file in radasyncupload1.uploadedfiles)     {         file.saveas(server.mappath("~/images/" + file.getname()), true);     } }

of course, add more complex logic here. checking existing files, creating proper file names, handling user permissions, etc.
