Localization
Updated over 6 months ago
To localize RadVirtualGrid to display control text and messages in a specific language:
-
All required classes for localization are defined in Telerik.WinControls.UI.Localization namespace.
-
Start by creating a descendant of the RadVirtualGridLocalizationProvider 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 RadVirtualGrid Strings
C#
public class MyRadVirtualGridLocalizationProvider : RadVirtualGridLocalizationProvider
{
public override string GetLocalizedString(string id)
{
switch (id)
{
case RadVirtualGridStringId.NoDataText: return "No data to display";
case RadVirtualGridStringId.FilterFunctionBetween: return "Between";
case RadVirtualGridStringId.FilterFunctionContains: return "Contains";
case RadVirtualGridStringId.FilterFunctionDoesNotContain: return "Does not contain";
case RadVirtualGridStringId.FilterFunctionEndsWith: return "Ends with";
case RadVirtualGridStringId.FilterFunctionEqualTo: return "Equals";
case RadVirtualGridStringId.FilterFunctionGreaterThan: return "Greater than";
case RadVirtualGridStringId.FilterFunctionGreaterThanOrEqualTo: return "Greater than or equal to";
case RadVirtualGridStringId.FilterFunctionIsEmpty: return "Is empty";
case RadVirtualGridStringId.FilterFunctionIsNull: return "Is null";
case RadVirtualGridStringId.FilterFunctionLessThan: return "Less than";
case RadVirtualGridStringId.FilterFunctionLessThanOrEqualTo: return "Less than or equal to";
case RadVirtualGridStringId.FilterFunctionNoFilter: return "No filter";
case RadVirtualGridStringId.FilterFunctionNotBetween: return "Not between";
case RadVirtualGridStringId.FilterFunctionNotEqualTo: return "Not equal to";
case RadVirtualGridStringId.FilterFunctionNotIsEmpty: return "Is not empty";
case RadVirtualGridStringId.FilterFunctionNotIsNull: return "Is not null";
case RadVirtualGridStringId.FilterFunctionStartsWith: return "Starts with";
case RadVirtualGridStringId.FilterFunctionCustom: return "Custom";
case RadVirtualGridStringId.FilterOperatorNoFilter: return "No filter";
case RadVirtualGridStringId.FilterOperatorCustom: return "Custom";
case RadVirtualGridStringId.FilterOperatorIsLike: return "Like";
case RadVirtualGridStringId.FilterOperatorNotIsLike: return "NotLike";
case RadVirtualGridStringId.FilterOperatorLessThan: return "LessThan";
case RadVirtualGridStringId.FilterOperatorLessThanOrEqualTo: return "LessThanOrEquals";
case RadVirtualGridStringId.FilterOperatorEqualTo: return "Equals";
case RadVirtualGridStringId.FilterOperatorNotEqualTo: return "NotEquals";
case RadVirtualGridStringId.FilterOperatorGreaterThanOrEqualTo: return "GreaterThanOrEquals";
case RadVirtualGridStringId.FilterOperatorGreaterThan: return "GreaterThan";
case RadVirtualGridStringId.FilterOperatorStartsWith: return "StartsWith";
case RadVirtualGridStringId.FilterOperatorEndsWith: return "EndsWith";
case RadVirtualGridStringId.FilterOperatorContains: return "Contains";
case RadVirtualGridStringId.FilterOperatorDoesNotContain: return "NotContains";
case RadVirtualGridStringId.FilterOperatorIsNull: return "IsNull";
case RadVirtualGridStringId.FilterOperatorNotIsNull: return "NotNull";
case RadVirtualGridStringId.FilterOperatorIsContainedIn: return "ContainedIn";
case RadVirtualGridStringId.FilterOperatorNotIsContainedIn: return "NotContainedIn";
case RadVirtualGridStringId.AddNewRowString: return "Click here to add a new row";
case RadVirtualGridStringId.PagingPanelPagesLabel: return "Page";
case RadVirtualGridStringId.PagingPanelOfPagesLabel: return "of";
case RadVirtualGridStringId.BestFitMenuItem: return "Best Fit";
case RadVirtualGridStringId.ClearSortingMenuItem: return "Clear Sorting";
case RadVirtualGridStringId.SortDescendingMenuItem: return "Sort Descending";
case RadVirtualGridStringId.SortAscendingMenuItem: return "Sort Ascending";
case RadVirtualGridStringId.PinAtRightMenuItem: return "Pin at right";
case RadVirtualGridStringId.PinAtLeftMenuItem: return "Pin at left";
case RadVirtualGridStringId.PinAtBottomMenuItem: return "Pin at bottom";
case RadVirtualGridStringId.PinAtTopMenuItem: return "Pin at top";
case RadVirtualGridStringId.UnpinColumnMenuItem: return "Unpin Column";
case RadVirtualGridStringId.UnpinRowMenuItem: return "Unpin Row";
case RadVirtualGridStringId.PinMenuItem: return "Pinned state";
case RadVirtualGridStringId.DeleteRowMenuItem: return "Delete Row";
case RadVirtualGridStringId.ClearValueMenuItem: return "Clear Value";
case RadVirtualGridStringId.EditMenuItem: return "Edit";
case RadVirtualGridStringId.PasteMenuItem: return "Paste";
case RadVirtualGridStringId.CutMenuItem: return "Cut";
case RadVirtualGridStringId.CopyMenuItem: return "Copy";
default:
return base.GetLocalizedString(id);
}
}
}
To apply the custom localization provider, instantiate and assign it to the current localization provider:
Assigning the Current Localization Provider
C#
RadVirtualGridLocalizationProvider.CurrentProvider = new MyRadVirtualGridLocalizationProvider();
The code provided above illustrates the approach to be used to localize the RadVirtualGrid and is not intended as a full translation.
