How can I pass a hidden field value to AjaxFileUpload control server side event. If it is possible by ContextKeys property than please show me the example.
I have a AjaxFileUpload as below. There is a id that i will get in client side passed from gridview. Now how can i pass that id to UploadComplete event so that I can access folder path based on that id on server side.
<ajax:AjaxFileUpload ID="AjaxFileUpload1" AllowedFileTypes="png,jpg,zip,ipa" önUploadComplete="AjaxFileUpload1_UploadComplete" runat="server"/>
Thanks in advance...
