I need a masked text box that can accept only IBAN values. The value is of type ROkk BBBB CCCC CCCC CCCC CCCC where kk are digits, BBBB must be uppercase letters and C must be uppercase letters or numbers. Is there any way to achieve this mask using RadMaskedTextBox?

Hello,


I hope the following approach will help you to achieve the required.

ASPX:
<telerik:RadMaskedTextBox CssClass="upper" ID="RadMaskedTextBox3" runat="server" Mask="RO## LLLL aaaa aaaa aaaa aaaa"
    DisplayMask="RO## LLLL aaaa aaaa aaaa aaaa">
 </telerik:RadMaskedTextBox>


CSS:
<style type="text/css">
    .upper
    {
        text-transform: uppercase;
    }
</style>

Thanks, but it doesn't solve my problem completely. This is actually the solution i found for now, but it's not perfect because 'a' masks allow users to type in anything, so for example ~!@#$%^&*()_+ are all valid characters according to the mask.

Hello Cristian,

You can refer to this documentation topic on how to build masks:

http://www.telerik.com/help/aspnet-ajax/input_radmaskedtextboxmasks.html

The uppercase mask is L. For uppercase and numbers I'm assuming if you add <L|#>, in the place of each a in the mask Shinu offered, it should only allow them to select an uppercase letter or number. So something like this:

RO## LLLL <L|#><L|#><L|#><L|#> <L|#><L|#><L|#><L|#> <L|#><L|#><L|#><L|#> <L|#><L|#><L|#><L|#>

I hope that helps.

Unfortunately, i can't set that kind of mask, <L|#> translates as "allow only the L and # characters". The only option i see is <A|B|C...Z|1|2...9> but there should be an easier way to implement this.

I guess listing all the letters is the only to go, since I have no clue why it doesn't accept the L as being a capital letter when used in an Enumeration.
