Localization
To localize RadFilterView to display control text and messages in a specific language:
All required classes for localization are defined in Telerik.WinControls.UI namespace.
Start by creating a descendant of the RadFilterViewLocalizationProvider class.
Override the GetLocalizedString(string id) method and provide a translation for the label and user messages. If a translation is not provided, the default value will be returned. This behavior is guaranteed by the call to the base GetLocalizedString method in the default clause of the switch statement in the example.
Below is a sample implementation of an English localization provider:
Localizing RadFilterView Strings
public class EnglishFilterViewLocalizationProvider : Telerik.WinControls.UI.FilterView.RadFilterViewLocalizationProvider
{
public override string GetLocalizedString(string id)
{
switch (id)
{
case RadFilterViewStringId.ClearCategoryFilterMenuItem: return "Clear Filter";
case RadFilterViewStringId.ClearAllFiltersMenuItem: return "Clear All Filters";
case RadFilterViewStringId.BooleanCategoryTrue: return "True";
case RadFilterViewStringId.BooleanCategoryFalse: return "False";
case RadFilterViewStringId.NumericCategoryFrom: return "From:";
case RadFilterViewStringId.NumericCategoryTo: return "To:";
default: return base.GetLocalizedString(id);
}
}
}
Public Class EnglishFilterViewLocalizationProvider
Inherits Telerik.WinControls.UI.FilterView.RadFilterViewLocalizationProvider
Public Overrides Function GetLocalizedString(ByVal id As String) As String
Select Case id
Case RadFilterViewStringId.ClearCategoryFilterMenuItem
Return "Clear Filter"
Case RadFilterViewStringId.ClearAllFiltersMenuItem
Return "Clear All Filters"
Case RadFilterViewStringId.BooleanCategoryTrue
Return "True"
Case RadFilterViewStringId.BooleanCategoryFalse
Return "False"
Case RadFilterViewStringId.NumericCategoryFrom
Return "From:"
Case RadFilterViewStringId.NumericCategoryTo
Return "To:"
Case Else
Return MyBase.GetLocalizedString(id)
End Select
End Function
End Class
To apply the custom localization provider, instantiate and assign it to the current localization provider:
Assigning the Current Localization Provider
RadFilterViewLocalizationProvider.CurrentProvider = new EnglishFilterViewLocalizationProvider();
InitializeComponent();
RadFilterViewLocalizationProvider.CurrentProvider = New EnglishFilterViewLocalizationProvider()
InitializeComponent()
