I think if the requirement is to allow the input in the format 1234,2345 then the following ValidationExpression
(\d+,)*\d+ for any number of digits in each set
and
(\d{4},)*\d{4} for exactly four number of digits in each set
may suffice.

hi VJ it is working fine on first line on multiline textbox but fail to work when enter valid 4 digit case id on next line.

Use the following expression
(\d+,\r?\n?)*\d+
(\d{4},\r?\n?)*\d{4}
It matches , entered at the end of the line.
Hope, this may serve the purpose.
Thank you.
