RadMaskedTextBox

[Elisabeth]

I'm trying to use the RadMaskedTextBox. What I need to do is to allow the user to enter 3 different formats.

Below are examples

123

123-456

123-456-789

If he enters 132 then there is nothing different but if he types in 1234 then as soon as he enters 4, I need to display the dash. It is the same for 7. I can't use a validator as I need it on the entry and not when he is validating the page.

I thought about using a mask but I don't want to display the dash when the page loads in case he only types in 3 digits. I thought about a regular expression but I don't know how to implement only when the user is typing and not validating.

Maybe the RadMaskedTextBox is not the right control to use.

Thank you for your help.

Hello Elisabeth,

I am afraid this functionality is not provided out-of-box. You will need to use the client events of the input to implement your logic ( OnValueChanged event for instance ).

I hope this helps.

Hi Eyup,

thanks for your reply.

I ended up using OnKeyPress and OnValueChanged and it works fine.

Regards.
