9 The DesignerOptionService service

The DesignerOptionService service is an abstract class of the namespace System.ComponentModel.Design. It provides methods for management of the option of design like the use of SnapLines, Grid or Smart Tags, etc (To consult the MSDN to know all its methods, properties and events). One recovers this service via the GetService method of the DesignSurface class, while passing the System.ComponentModel.Design. DesignerOptionService  type in parameter. 

Let us examine somebody of these methods, properties and events:

- The GetOptionValue method which turns over the value of the option passed in parameter.

- The SetOptionValue method   which defines a value in an option.

There is no DesignerOptionService service by defect in DesignSurface. We will use the System.Windows.Forms.Design. WindowsFormsDesignerOptionService class which will facilitate the management of this service to us:

class Designer : System.ComponentModel.Design.DesignSurface {     public Designer()     {         // Service of creation of name         ServiceContainer.AddService( typeof(System.ComponentModel.Design.Serialization.INameCreationService), new NameCreationService());         // Service of management of the toolbox             ServiceContainer.AddService( typeof(System.Drawing.Design.IToolboxService), new ToolBoxService());           // Service of view of the host         ServiceContainer.AddService(typeof(ViewService), new ViewService());           // Service of management of the menus        ServiceContainer.AddService( typeof(System.ComponentModel.Design.IMenuCommandService), new MenuCommandService(this.ServiceContainer));           // Management of options of design         System.Windows.Forms.Design.WindowsFormsDesignerOptionService designerOptionService = new System.Windows.Forms.Design.WindowsFormsDesignerOptionService();         // It is specified that one goes use the grid to place the components         designerOptionService.CompatibilityOptions.ShowGrid = true;         ServiceContainer.AddService( typeof(System.ComponentModel.Design.DesignerOptionService), designerOptionService);     } }

To compile and launch the project and here what you obtain:

From now on one can move the controls according to the grid which has just appeared.
