Globalization and Controls in C#

December 24, 2011 Leave a comment

Over the last couple of years I have found myself seeing “globalization” being added as a requirement more and more frequently. Microsoft has done an amazing job making it easy to easily implement a display interface that is culture friends. The CultureInfo Class provides an easy to use way of displaying dates, currency, digit grouping and so on.

In an effort to show once again how easy and time saving it is to create your own controls I created a simple “globalized” phone number formatting (masked) text box.

The idea is to create two dictionaries, one with the phone number formatting with area code and one without. Overriding the OnCreateControl to select the appropriate Mask to apply. I couldn’t find a way to get the phone number formatting from the CultrueInfo, it doesn’t look like there’s a way. Basically I have the dictionary that you can add full codes, language code only or country code only. It will look for the full code first, if there’s no match it will look for the country code and lastly the language code. Finally if there is no matches on any of the above it will return the entry with the key “”. It’s the default for when globalization is off as well. The property Globalize is intended to be able to disable the globalization just in case.

As always you can download the sample  here.

Wiki article on the subject is here.
