hello i have repeater to show the data and i have text editor to insert the data in repeater and i have fileupload control to upload the file.
when insert data in editor and attach file then i press the submit button then whole page refresh i try with updatepanel but failed..i want insert data with file upload inside repeater without refreshing the whole page.tell me as soon as possible thanks in advance.

Can you post up some code? If you have added a script manager and an update panel around the section you want to update via AJAX it should work.
