thanks for the other validation code. I have got that and implemented in my code but i have a doubt in that.
As we try to put string values its not allowing to do tht it gives us message its right but by mistake i have entered a wrong numerical value in the textbox then i have to use the backspace or delete to change it, but its not allowing me to do that.
as when i try to use the backspace or delete button its giving the error that only numeric data. but i should be allowed to do the changes. Then how this can be done ?
what change in the code should be made plz help..............
i think i am able to tell u what i want to and u have got whats my doubt. plz give solution to it??????????
