Hi i am new to this
I created a masked text box but dont know how to define a mask
For example i want the textbox to allow only numbers and maximum size of input must be 4
Another would be that the maximum size should be 2 and it can allow values 0-9 and a-f (yes i am looking for hexadecimal input)
Is there a way i can make a Textbox or Masked Text Box to conform to a Regular Expression(System.Text.RegularExpressions)???
