Syntax
public class MainFrameBarManager : BarManager, IThemeProvider, IDisposable, ISupportInitialize, IBarItemsRepository, ISerializable, IDeserializationCallback, IIgnoreWorkingArea, IVisualStyle, IMessageFilter
Remarks

Make sure to take a look at the BarManager's documentation before you start using this derived class.

You should associate an instance of this class with a form that will be the main form in an MDI scenario or the single top-level form in an SDI scenario.

Note that in an MDI scenario, optionally you can provide the MainFrameBarManager prior knowledge of the all the child form types that it might parent, in order that the menus and tool bars provide a seamless interface to the user even though they are part of different child forms' BarManager. You do this using the MainFrameBarManager's RegisterMdiChildTypes(Type[]) method.

If you do not call the RegisterMdiChildTypes method, the child menus will be added/merged with the parent menus as and when the child forms are added to the mdi parent.

When using this class in a SDI Form, it is recommended that you put all your controls in the form within a System.Windows.Forms.Panel with the DockStyle.Fill property set, so that they resize as the menu's height changes. This is necessary because the menus occupy the client area of the form. This is not necessary if you are using this in an MDI Container (IsMdiContainer property set to true).

Examples

Take a look at our XPMenus samples under the Tools\Samples\Menus Package folder for usage example.

Remarks

Specifies the UserControl that will be used in the Customization dialog to allow the end user to customize the application's menu structure.

This property allows you to provide a custom look for the customization dialog in your application. To do so, derive a class from the default CustomizationPanel class (the Visual Studio make this a snap using the "Add/Add Inherited Control..." menu item in the Solution Explorer view, even providing your derived class with a design time to work with), instantiate that class and assign that instance to this property, all this from within your form's constructor.

Property Value
Type Description
System.Boolean

True if it available; False otherwise.
Remarks

If the application is run for the very first time then user-customization info will not be available and this method will return false. For subsequent runs, this method will return true if the user-customization info persistence is turned on through the AutoPersistCustomization property, false otherwise.

Overridden. See LargeIcons.

Declaration
public override bool LargeIcons { get; set; }
Property Value
Type Description
System.Boolean

MainMenuBar

Returns the main-menu toolbar in the form.

Declaration
public Bar MainMenuBar { get; set; }
Property Value
Type Description
Bar

A Bar object. Can be null.
Remarks

During design-time a Bar is designated as the main-menu by including the IsMainMenu enum in the BarStyle property.

However, during runtime, a new Bar instance is created by merging the main-menus of the mdi container and all the mdi children. This merged main-menu Bar is exposed through this property. You can modify insert items into the main-menu during runtime in code, if necessary, through this bar.

Merging takes place when you call RegisterMdiChildTypes(Type[]) or when the form gets activated. If you call this property before merging takes place then the Bar in the Bars collection with the BarStyle property containing the IsMainMenu enum will be returned. Will return null, if no such bar exists.

Indicates whether, on application shutdown all persisted information should be reset.

Declaration
public virtual bool ResetCustomization { get; set; }
Property Value
Type Description
System.Boolean
Remarks

Note that setting this property will reset the persisted information only when application is shutdown and so the reset state will be seen only when the application is restarted (not as soon as this property is set).

SelectedItem

Gets or sets the selected bar item. (overridden property)

Declaration
public override BarItem SelectedItem { get; set; }
Property Value
Type Description

Parameters
Type Name Description
AppStateSerializer serializer

The state serializer.
System.Boolean loadBarsState

LoadCustomizationInfo(AppStateSerializer)

Loads the user customized information from the specified persistence medium.

Declaration
protected virtual void LoadCustomizationInfo(AppStateSerializer serializer)
Parameters
Type Name Description
AppStateSerializer serializer

A reference to the AppStateSerializer instance.
Remarks

This method is not public because loading and saving of the user customized info needs to be performed at a specific time and the framework doesn't support calling this method at any other time.

To customize this persistence mechanism, please override this method and provide a custom AppStateSerializer instance.

LoadDesignerBarState()

Resets the toolbar positions to the default designer set positions.

Declaration
public void LoadDesignerBarState()
Remarks

Calling this method will move the toolbars to the designer set positions. Note that this applies only the toolbars in the MainFrameBarManager not the ones in the ChildFrameBarManager (that manages a MDI Child). This is because the toolbars in an mdi child do not have any positional information associated with them.

RegisterMdiChildTypes(Type[])

Registers the MDI child form types that could be created during the course of an MDI application.

Declaration
public virtual void RegisterMdiChildTypes(Type[] formTypes)
Parameters
Type Name Description
System.Type[] formTypes

An array of Form types.
Remarks

Explicit MDI Merging:

Calling this method merges the menus and toolbars of the child forms with that of the main form (in an MDI scenario), immediately. The toolbars from the child forms will then be available in the "Toolbars List" for user-customization.

You should call this in either your MDI Parent Form's constructor or Load event handler.

This method is intended to support the following scenario. In an MDI app, you might want the XPMenus framework to merge the child form types's menus and toolbars that the MDI Parent will be parented to during the course of the application, even before the child forms are visible. Doing so will then present a seemless interface to the user with the toolbars and menus from all the different child form types being available for user-customization, all the time.

Also a dummy instance of the child form types will be created at this time to retrieve the bar items, requiring the child types to include a default constructor.

Take a look at our User's Guide (section MDI Merging) for more information on how the MergeType, MergeOrder and the Text properties of BarItems influence the merge behavior of those BarItems.

Automatic MDI Merging:

If you do not call this method explicitly with your child form types, the framework will call it for you when a child form (with XPMenus) gets loaded and then automatically unregister (using the UnregisterMdiChildTypes(Type[], Boolean) method) the child form type when all the corresponding instances of the child type are closed.

Delayed MDI Merging:

Sometimes you will dynamically load new child form types into your MDI. In such cases you could optionally call this method in a later stage after you access these new types and before instances of such types get parented by the MDI parent. If you do not call this method, the child's menus will still be merged (see above "Automatic MDI Merging"), but they will be removed when the child form is closed.

In such dynamic child-form loading scenarios, you might also not know whether your child forms are associated with a ChildFrameBarManager in order for you to register such types using this method. You can determine that using the GetManagerFromForm(Form) method.

Use the UnregisterMdiChildTypes method to "unmerge" toolbars and menus from one or more child form types. Take a look at the method reference for more information.

Exceptions
Type Condition
System.ArgumentException

Will be thrown if either of the types in the array is not derived from the Form class, if either of the types do not have a default constructor, if the passed in types do not have a ChildFrameBarManager associated with them or if the form associated with this MainFrameBarManager is not an MdiContainer.

Declaration
[Obsolete("ProvidePersisteceID is deprecated, please use ProvidePersistenceID instead.")]
public event ProvidePersistenceIDEventHandler ProvidePersisteceID
Event Type
Type Description
ProvidePersistenceIDEventHandler
Remarks

The default persistence logic assumes that there will be only a single MainFrameBarManager in an application. But that might not be the case if you have more than 1 MDI parent. In such cases, the persisted state of one MDI parent will get overridden by the other since the default logic doesn't distinguish these 2 different instances.

ProvidePersistenceID

Declaration
public event ProvidePersistenceIDEventHandler ProvidePersistenceID
Event Type
Type Description
ProvidePersistenceIDEventHandler
Remarks

The default persistence logic assumes that there will be only a single CommandBarController in an application. But that might not be the case if you have more than 1 MDI parent. In such cases, the persisted state of one MDI parent will get overridden by the other since the default logic doesn't distinguish these 2 different instances.
