To provide a custom designer for a Component or System.Windows.Forms.Control, you should decorate the class with this attribute. (See EditorAttribute for information on custom type editors for a specific property within a component).

You can specify the DesignerTypeName: the name of the type that implements the System.ComponentModel.Design.IDesigner interface on behalf of our designable class. You can also specify the base type of the designer with DesignerBaseTypeName. While this would default to System.ComponentModel.Design.IDesigner, you can specify a different System.ComponentModel.Design.IDesigner-derived interface such as System.ComponentModel.Design.IRootDesigner

public sealed class DesignerAttribute : Attribute {
// Public Constructors
   public DesignerAttribute(string designerTypeName);
   public DesignerAttribute(string designerTypeName, string designerBaseTypeName);
   public DesignerAttribute(string designerTypeName, Type designerBaseType);
   public DesignerAttribute(Type designerType);
   public DesignerAttribute(Type designerType, Type designerBaseType);
// Public Instance Properties
   public string DesignerBaseTypeName{get; }
   public string DesignerTypeName{get; }
   public override object TypeId{get; }
// overrides Attribute
// Public Instance Methods
   public override bool Equals(object obj);  // overrides Attribute
   public override int GetHashCode();  // overrides Attribute
}
