WPF EXTENDED MENU HOW TO

Generally there are two options for this, and interface or an abstract class.

Now to standardise the menu items so we can bind to them. Public void RemoveMenuItem(MenuItem menuItem) MenuItem parent = allMenuItems.Find(x => x.Name = parentName) Public void AddMenuItem(MenuItem item, string parentName = '') List parentItems = allMenuItems.FindAll(x => x.Parent = null) I have purposely omitted this to reduce code complexity, and in most cases, the top-level menu items will probably be fixed. This means to make it dynamic once it has been created, you may want to replace the list with an observable collection (as sub-items will be) or if left as a list, ensure we notify any binding controls (in this case the hierarchical data template) of any changes by implementing the INotifyPropert圜hanged interface in the view model. In the code below, I have set the top-level items as a list. Out top-level items will be items like ‘File’, ‘Edit’ etc. This needs to provide the ability to add and remove items to the menu, and to return our top-level items to the hierarchical data template. In this first post, I will cover the service controller and standardising our menu items.įirstly, the menu service. A way of standardising all the menu items to ensure consistency.A service to control the adding and removing of items on the menu.A WPF form with a hierarchical data template to display the menu.To create a dynamic menu, we need the following: Where necessary, I will note some options for extending the menu bar to provide increased functionality. For brevity I have limited the scope to exclude any real styling and have created a very simple example that can easily be extended.

In the next 3 posts I will demonstrate how to create a dynamic menu bar that we can add and remove items to at run time. WPF provides some really nice features allowing us to create dynamic user interfaces. Please note: This page has now been moved.
