  <p>Please refer the uploaded image which got when I run my web application.</p>
  
  <p>Now i want to edit the values which i select from gridview and fill given checkboklist control with only checked items which is in database.</p>
  
  <p>For example when I click <kbd>edit</kbd> for the item whose id is 5, it has 2 values "Yellow" and "Brown", so now only that values in checkboxlist control should be checked.</p>
