A base class for implementing custom services used to substitute the default command factory service.
Namespace : DevExpress.XtraSpreadsheet.Services
Assembly : DevExpress.Spreadsheet.v25.2.Core.dll
NuGet Package : DevExpress.Spreadsheet.Core
public class SpreadsheetCommandFactoryServiceWrapper :
ISpreadsheetCommandFactoryService
Public Class SpreadsheetCommandFactoryServiceWrapper
Implements ISpreadsheetCommandFactoryService
All commands in the SpreadsheetControl are created using the command factory service. You can substitute the default command factory service with its descendant designed to create a custom command instead of the default command. Subsequently, the specified custom command is used in all SpreadsheetControl operations instead of the replaced command.
The following code snippet demonstrates a custom service used to substitute the Clear Contents formatting commands located in Ribbon and context menu with a custom command.
public class CustomService : SpreadsheetCommandFactoryServiceWrapper {
public CustomService(ISpreadsheetCommandFactoryService service)
: base(service) {
}
public SpreadsheetControl Control {get;set;}
public override SpreadsheetCommand CreateCommand(SpreadsheetCommandId id)
{
if (id == SpreadsheetCommandId.FormatClearContents || id == SpreadsheetCommandId.FormatClearContentsContextMenuItem)
return new CustomFormatClearContentsCommand(Control);
return base.CreateCommand(id);
}
}
Public Class CustomService
Inherits SpreadsheetCommandFactoryServiceWrapper
Public Sub New(ByVal service As ISpreadsheetCommandFactoryService)
MyBase.New(service)
End Sub
Public Property Control() As SpreadsheetControl
Public Overrides Function CreateCommand(ByVal id As SpreadsheetCommandId) As SpreadsheetCommand
If id = SpreadsheetCommandId.FormatClearContents OrElse id = SpreadsheetCommandId.FormatClearContentsContextMenuItem Then
Return New CustomFormatClearContentsCommand(Control)
End If
Return MyBase.CreateCommand(id)
End Function
