"WHATEV When we run this in the simulator, as expected we get a simple page with a Share toolbar button. Since the default behavior is to place toolbar items into the primary location, this button appears at the top right end of the navigation bar. Try it, it should work: Switching to the Secondary Toolbar.
How do we find it? Easy it will be the only UIToolbar-derived subview that isnt actually a UIToolbar (remember, they inherited that private class from it). If we find it, we pluck it out from the visual tree. This can be done easily within ViewWillAppear of the custom NavigationPage renderer: public override void ViewWillAppear (bool.

Creating a toolbar add on!
Xamarin Forms is a really great platform for mobile app development we have used it on several apps now and had much better results than when trying to use the native SDKs directly. Every now and then though you run up against a roadblock with the default renderer implementations where some feature (perhaps a key.
Of course the downside of this approach is that it only works with ToolbarItems which are using Command bindings (not Clicked events) but surely anyone using Xamarin Forms is also using some form of MVVM and Command binding right? I mean after all, we arent a bunch of VB savages! public class ToolbarRenderer : PageRenderer.
services : This is the driver class when we select the object service creating a toolbar add on (menu option)) from the GOS toolbar. For time being we will create custom toolbar your own keep this as the CL_GOS_SRV_ATTACHMENT _LIST. Class for Gen. This table can be maintained using SM30.
What is a secondary toolbar? Xamarin Forms supports the notion of Page-level toolbars. These are represented by the olbarItems collection, and each ToolbarItem represents a clickable button that is hosted within the toolbar. In fact, there are two toolbars the main primary toolbar that fills the right end of the navigation bar at the top.
Native secondary toolbar in iOS (appears at the bottom of the screen) In my case, I desperately wanted to have a bottom toolbar with the iOS Action built-in system icon (usually used for export or send or share functions). The default Xamarin Forms behavior was not an acceptable substitute. I explored many options including implementing.
Essentially, if we see any UIToolbars then we want to let them self-position themselves at the bottom (there shouldnt be more than one and then resize anything else (the pages content) to fill the remaining area. Easy enough: public override void ViewDidLayoutSubviews ewDidLayoutSubviews UIView subviews bviews. Where (v v! NavigationBar).ToArray var toolBarViews subviews. Where (v.
Remove the next service from the option which will come at last. This is very important. After following these steps, the toolbar options will look like: In the next post, we will see how we can use our custom class to generate our fully customized code i.e. Instead of the class CL_GOS_SRV_ATTACHMENT _LIST, we will use custom class ZCL_SO_LIST.

Our toolbar will then get noticed by the NavigationPage renderer above, and get placed appropriately. We also need to be sure to remove our UIToolbar when the pages view disappears otherwise the toolbar would remain visible after navigating away. And of course, all of that would be for nothing if we didnt actually wire up.
So lets see about fixing the situation. Fixing the NavigationPage Renderer First of all, lets fix the default renderer for NavigationPage. There are two things going on in the default renderer that contribute to this problem first, the NavigationPage is where we will find that ugly and unsavory private UIToolbar. Second, the default renderer performs.
Xamarin Forms is doing a few things here. First, they are creating their own UIToolbar using a private nested class (so you cant really do anything about it). Their toolbar uses custom UIViews to display the toolbar items, and you dont really get much control over the process or visual styling. In addition to this.

This just wraps the previous page with a Navigation container and also provides a Command to be bound to the Share toolbar item. Clicking Tapping the toolbar item will display a plain alert. Here is the full code for the App class (we.
This next service field must be set when we need to put the custom option in between other options. Control: We will select this, since we want to generate our output in the Custom Container. Commit Work: We will not select this option because we dont want to commit the work. Along with creating a.
An Example App In order to demonstrate this solution, lets create an extremely simple example app. I created a new Xamarin Forms app in Xamarin Studio (only bothering to select iOS platform no need to add an Android project for this demo). To this app, I added a new Content Page (XAML ) named MainAppPage.
