Hi in my country we can phone anyone by only 7 number... Eg 2345897
and sometimes we represent it in this format 234-5897 by a - (negative)..
i want to tell the txtPhoneNumber that after 3 numbers ahve been entered a negative should be place and it should comes automatically ...
i do not want any user to press on the negative frm the keyboard..
I need help 4 this ..
