This sample code enables you to substitute a default SaveDocumentCommand with a CustomSaveFileCommand class object, providing additional functionality.
public static class MyFactoryHelper {
public static void SetMyNewCommandFactory(RichEditControl control) {
var myCommandFactory = new CustomRichEditCommandFactoryService(control, control.GetService<IRichEditCommandFactoryService>());
control.ReplaceService<IRichEditCommandFactoryService>(myCommandFactory);
}
}
public class CustomRichEditCommandFactoryService : IRichEditCommandFactoryService {
readonly IRichEditCommandFactoryService service;
readonly RichEditControl control;
public CustomRichEditCommandFactoryService(RichEditControl control,
IRichEditCommandFactoryService service) {
this.control = control;
this.service = service;
}
public RichEditCommand CreateCommand(RichEditCommandId id) {
if (id == RichEditCommandId.FileSave)
return new CustomSaveDocumentCommand(control);
return service.CreateCommand(id);
}
}
public class CustomSaveDocumentCommand : SaveDocumentCommand {
public CustomSaveDocumentCommand(IRichEditControl control)
: base(control) {
}
protected override void UpdateUIStateCore(ICommandUIState state) {
base.UpdateUIStateCore(state);
// Disable the command if the document has less than 5 paragraphs.
state.Enabled = Control.Document.Paragraphs.Count > 5;
}
protected override void ExecuteCore() {
// Cancel execution if the document contains less than 7 paragraphs.
if (Control.Document.Paragraphs.Count > 7)
base.ExecuteCore();
else MessageBox.Show(@"You should type at least 7 paragraphs to be able to save the document.",
"Please be creative", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
