RadGantt supports built-in localization through Global resources. Similar to other Telerik UI controls you can use the resx files to localize the control with minimum efforts.
The resource files should be placed within the App_GlobalResources folder in your application. You can either create your own language pack (see below) or use an existing one (if available for your language). Telerik controls installation wizard automatically copies the built-in resources to the App_GlobalResources in your local installation.
To change the current language/resource you should set the Culture property accordingly.
RadGantt's default Culture is taken from the page's CurrentUICulture .
Here is how to localize your Rad in simple steps:
Create a new resource file or copy an existing one from the App_GlobalResources in your installation folder
Add the resource file (resx) file to the App_GlobalResources folder in your application. Note that you should have two files as a bare minimum - RadGantt.resx and the localization file itself - for example RadGantt.en-GB.resx
Set the Culture property to the corresponding language (for example: it-IT, en-GB, ja-JP and so on)
The resource files are represented in a human-readible format (XML) and can be easily modified either in the built-in Visual Studio resource editor or directly in the file, by hand.
The process of creating a new global resource follows the same pattern as in RadEditor and RadScheduler controls.
Make a copy of the RadGantt.resx file and save it as RadGantt.YOURLANGUAGE.resx (for example: RadGantt.ja-JP.resx)
Replace the default strings with the translated ones
Set the Culture property to the relevant language
Please do not modify/remove the ReservedResource key.
We encourage that you submit your localized resource files. Your efforts will be rewarded accordingly.
