I am using a text box control to input PostCode. The Format in which the postcode should be entered is 'A9A9A9'(alternate alpha and numbers). I have set the Input Mask property as '!9!9!9' (so that the alphabets are stored as capital letters) and the format property as K(so that the entire control is selected for data entry). Despite the restrictions I can enter a value of '123456'. Please help. Is there any other property I can set to stop accepting '123456' as a value.
Thank you.
