Formatting a text field in MM / YYYY

Question

I have a text box in my web forms (ASP.NET Web Forms) that I want to display something like this:

MM / YYYY

I want this "/" to be in the middle when the user enters the month and year. How to do it in C #?

Answer 1

Take a look at the MaskedTextbox class (for Windows Forms anyway ... I see that you have now specified it as Web Forms).

Answer 2

I would look at the jQuery plugin for nested input:

https://plugins.jquery.com/maskedinput/

It seems like this is perfect for what you need to do.

The implementation is as follows:

jQuery(function($){ $("#date").mask("99/99/9999"); $("#phone").mask("[phone]"); $("#tin").mask("99-9999999"); $("#ssn").mask("999-99-9999"); }); 

Here you can see the demo:

Answer 3

If you are using Windows Forms, check out the MaskedTextBox class. If you are using WPF, look at the FilteredTextBox or possibly MaskedTextBox . If WebForms is ASP.NET, there are other options, such as a masked text field or various jquery features.

Answer 4

We will use a date control that supports the selection of the month / year OR split the field into two separate fields, one month for the other throughout the year.

For a web application, it's usually best to just split it up. That way you cover most of the possibilities.

If you insist on keeping it in one field and don’t want to use a specially designed control, then don’t worry about the oblique line and parse as soon as the field is published ... But this should be the last resort.
