Cancel Key press event
- by Asim Sajjad
How can I return the key, mean if I want to allow only interger value in the textbox , how can I don't allow user to not enter value other then integer, regarding, keypress event, I know there are other ways such as expression to match the string value, but I want to not assign invalid value to the textbox.
if (( value 0 a&&(value <=9))
then assigned
else
return
thanks in advance
