title: Preventing multiple users to edit the same list item in sharepoint 2010
body: <p>We have developed a custom webpart with multiple controls and deployed on sharepoint 2010 site which accepts inputs from the user and once the user clicks on the submit button all the values are stored in the sharepoint list with one of the columns being a hyperlink. When the user clicks on this hyperlink , through the query string he will redirected to the same form again.</p>
  
  <p>I would like to know if the user has clicked on this hyperlink to make editions to this form, can we avoid another user from making changes to this form?</p>
  
  <p>Please share your thoughts on this.</p>
