I have a textbox for user to enter the asset number which consists of "AST" follow by 6 numbers. Can I customise the format of the textbox to align with our asset number and if yes, how can I do it? Thanks
Examples of the asset number? AST001234, AST000089, etc.
So
1) If the user did not enter "AST" but only enter 6 numbers, I would like the textbox to add "AST" in front of the numbers to result in format "AST000000"
2) If the user did not enter "AST" and only enter 4 numbers, I would like the textbox to add "AST and fill in missing numbers as "0" to result in format "AST004444"
3) If the user enter "AST" and only 3 numbers, I would like the textbox to fill in missing numbers as "0" to result in format "AST000333"
