Localization

Wisej.NET fully supports localization using .NET and Visual Studio standard localization features.

Localizing the UI

All top-level controls in Wisej.NET support UI localization.

To enable localization features for a Form, Page, UserControl, or Desktop component:

1. In design mode, set the Localizable property to true
2. Once enabled, you can switch languages in the designer

Use the Language dropdown property to select the language for localization:

UI localization allows changing multiple properties per language switch, commonly:

• Size
• Location
• Text
• Colors
• Images

Localizing the System

Wisej.NET supports full localization of system resources including:

• MessageBox buttons
• Calendar control labels (month/day names)
• Standard numeric, percentage and currency formatting/parsing

Built-in Formats

• Numeric, Percentage, Date, and Currency

  Handled automatically for all supported languages worldwide.

• Date Labels: Months and Day Names

  Handled automatically for all supported languages worldwide.

• System Resources

  Wisej.NET system resources are localized in:

  • English
  • German
  • French
  • Italian
  • Turkish
  • Spanish
  • Portuguese

  For other languages, create a Resources-[LANG].resx file in either:

  • Root project folder
  • /Resources folder

  Add localization labels as needed. See How to: Create a Localized Resource File.

  Label	Description	Default Value
  $Ok	OK Button in MessageBox/system dialogs	OK
  $Cancel	Cancel Button in MessageBox/system dialogs	Cancel
  $Yes	Yes Button in MessageBox/system dialogs	Yes
  $No	No Button in MessageBox/system dialogs	No
  $Retry	Retry Button in MessageBox/system dialogs	Retry
  $Ignore	Ignore Button in MessageBox/system dialogs	Ignore
  $Abort	Abort Button in MessageBox/system dialogs	Abort
  $Next year	Next-year navigation tooltip in calendar controls	Next Year
  $Next month	Next-month navigation tooltip in calendar controls	Next Month
  $Last year	Last-year navigation tooltip in calendar controls	Last Year
  $Last month	Last-month navigation tooltip in calendar controls	Last Month
  $Offline	Offline connectivity loss notification	Offline

Localizing Resources

Beyond system localization, you'll likely need to localize application resources (strings, images, etc.).

Create .resx files as needed using the approach above. See How to: Create a Localized Resource File.

Use the ResourceManager class to retrieve localized values. Wisej.NET handles thread culture switching for client requests.

C#

var RS = new ResourceManager("Localization.Resources", this.GetType().Assembly);
var title = RS.GetString("Title");

VB.NET

Dim RS as ResourceManager = new ResourceManager("Localization.Resources", Me.GetType().Assembly)
Dim title as String = RS.GetString("Title")

Detecting/Switching Browser Language

Wisej.NET automatically detects browser language and switches application/system resources accordingly.

You can force a specific language for the application (user session) by:

1. Setting the culture property in Default.json (default is "auto"). See Configuration.
2. Using one of these methods:
   • Assign Application.CurrentCulture property
   • Add lang URL parameter (e.g., http://localhost/myapp?lang=de for German)

When current culture changes from the session's initial culture, Wisej.NET raises the Application.CultureChanged event.

warning

Designer-localized controls update only at creation. No built-in mechanism exists to change already-created controls. To update existing controls either:

• Re-create the container and call InitializeControl
• Write custom code to reapply resources
