Hello all,

I am stuck with a trivial problem. I want to format data entered by user into text boxes separated with comma.
Ex : 12,345.00 instead of 12345 . It should also contain the decimal part.
I tried with ajax masked edit extender but my client is not comfortable as it shows commas and dots while typing.
I am looking for easy client side formatting as I have many text boxes. Once user enters data , format should change as above. I am attaching my code using ajax extender though it may not help with my problem. Please help me. Thanks in advance :)

   Mask="9,999,999.99"
