Checkbox id changes after post action



User has a grid with checkboxes on each row, and used .pySelected as a property for the checkbox.

The checkboxes have an action defined on them to do a Post Value on Change. On initial page-load the checkbox ID's are numbered sequentially. (pySelected1, pySelected2, pySelected3, pySelected4, and so on).

On checkbox click the value is being posted, but the ID changes to 'pySelected' for each checkbox that is clicked.

User requires the checkbox ID to stay unique after a post.
