title: How to reload the same page on a button click , with the data from database and ignoring the changes
body: <p>I have an aspx page with repeater control on it used for showing the data.The user can modify the data inside the repeater but the data will not get saved until the SAVE button is hit.
  I also have an UNDO button on the page. If the user clicks this button, I want to reload the page and discard the changes made by user (similar to UNDO functionality in MS Office)
  I need to show him the same data that was shown when the page was loaded for the first time.</p>
  
  <p>Kindly help me with this.</p>
  
  <p>Thank you ! </p>
