Limit the numerical value in a MultiLine TextBox

The requirement is :

In a Multiline text box, user should be able to add either 8-digit numerical number or 10-digit numerical number separated by commas. 

Example: 1234567891,2345678911, and so on....

There is no limit on the overall length of text box , but the numerical values within the text box should be either 8 or 10.

I have already written the code for limiting numerical values, but don't know how to restrict values with in the text box.

Help will be appreciated.

you can use regular expression validator for the same.

Below is the regular expressions :

For Only 10 digits :

^[0-9]{10}( *, *[0-9]{10})*$

For Either 8 or 10 digits :

^(\d{8}|\d{10})( *, *(\d{8}|\d{10}))*$
