I Have a list called "Register" it contains a column named as "status". Now my requirement is once the status is "approved" or" rejected" that particular row shod be disabled ? is there any way to do it either through SharePoint or SharePoint Designer ?
Here is the picture of my list view .

I tried through Validation settings but i am not able to disable the row. Itried through Workflow (basic) but still it is enabled. Any help ?
