I would like to create a error bar like the Mail app of Windows 10.
It shows the error and few seconds later, it is hidden with an animation that move the panel to the edge.
I suspect that I could use EdgeUIThemeTransition or PaneThemeTransition but I am not clear how to use it. The image show the error panel (red color). Is must be a StackPanel? a Popup? ...
Its probably made by creating custom Panel (Grid / StackPanel ...), injected into the view by xaml or code behind. The animation can be easily created manually by code.
Use DoubleAnimation to animate the TranslateX of the Transfomer of the panel for example.

My goal is to view the content of the bottom page from the top of the other content page. In order to accomplish this, I used PushModalAsync to navigate and set the BackgroundColor property of the navigation page to Transparent. I can view the content on the bottom page on Android. However on the iOS platform, a black color is always displayed and I am unable to read the content of the bottom page. Why is the background color always black even when it is set to be transparent in PushModalAsync?
Note: The iOS platform displays a white screen when I change the navigation to PushAsync.
Expected Behavior:
Background color should not be black and it should be transparent when navigating using PushModalAsync
Actual Behavior:
Background color is always black even when the content page background color is set as transparent when navigating using PushModalAsync

If you want to do EXACTLY like that, it is not possible (it will require so much work that you can't expect someone to provide you the solution here).
On iOS that control (ViewController) is drawn that way in that presentation mode. So as long as you use that control and that mode it will work that way irrelevant if you use Xamarin or something else. As ViewControllers are most basic controls it is not realistic to replace them with something else. But you can replace presentation mode. In Xamarin.Forms you can do that this way:
<ContentPage ...
xmlns:ios="clr-namespace:Xamarin.Forms.PlatformConfiguration.iOSSpecific;assembly=Xamarin.Forms.Core"
ios:Page.ModalPresentationStyle="FormSheet">
...
</ContentPage>
This will result in somewhat different visual presentation but that is the only way to have one ViewController drawn over another without going into some deep customization that would require tons of code, especially on Xamarin.Forms.
You can also try some other values, but the default value will not work.
In iOS, the hierarchy is managed by the view controller. Each page has a separate view controller. A page consists of a window, a root view, and a subview. You cannot see the layout of the previous page by setting the background color to be transparent.
For more details, you can refer to the following documents:

I am using Visual basic 2010 for coding. I have develop the code on desktop. Where I have adjusted form as per my desktop screen. I am going to run the application on Laptop. When I run the app the screen is not fitting to Laptop screen. SO I deciede to include vertical scroll. If moved up and down we can see all the parameter.
How can I do it?
I have added image for reference.
The scroll bar(s) should be inside the individual TabPages. You should set the Anchor and/or Dock properties of the TabControl so that it resizes with the form and set the AutoScroll property of each TabPage to True if you want it to display scroll bars if and when any of its child controls are outside its viewable area.
How do I get the new toolbar item style of OSX Yosemite?
I created a standard toolbar, but the buttons don't have that button-like look. Do I need to drag actual buttons to the toolbar to get this look?
What I have:
What I want (that round bezel and white background):
There are two types of items in toolbars, image items and view items. It looks like you have an image item. You seem to want a view item where the view is an NSButton configured as a round textured button. So, yes, you should drag actual buttons to the toolbar.
I would not attempt to control the button background. You should use the button as-is to get the default system appearance. Apple recommends using a PDF template image (all black with the alpha channel used to make the image). The button itself would not have a title/label. Rather that would be on the containing toolbar item.
It looks like you may have applied an internal blue "glow" or highlight to your image. Generally, you should not do that. Let the frameworks apply appropriate effects to the template image automatically based on the button state and shows-state-by mode.

Works just fine for my Cocoa app under Yosemite -
are you actually setting the template property for your icon images..?
From the NSImage docs:
The 'template' property is metadata that allows clients to be smarter
about image processing. An image should be marked as a template if it
is basic glpyh-like black and white art that is intended to be
processed into derived images for use on screen.
I am trying to show an entrybox after tapping an image.
I have this:
And I want to achieve this after tapping on the keyboard image:
The gesture is not a problem I add this lines:
keyboard.GestureRecognizer.Add(new TapGestureRecognizer((view,args) =>
{
ShowEntryBox();
})):
The problem is that I do not know how I can show the entry box, I use XAML. I tried relativelayout and I saw samples of absolutelayout but I can not achieve it.
I am using Xamarin forms to android and ios App.
Perhaps try a Grid?
In the center cell you can create two child controls:-
*) Label control.
*) Entry control.
and then give these controls each a name and set the appropriate .IsVisible value on each of these two controls accordingly, or alternatively hook the IsVisible for each of these controls into a ViewModel and set the state there instead.
I am trying to create an animation to a control.
So think of the animation and control of a now playing page on most touch screen devices. You see the control (album photo) and swipe either way and get it to slide off the screen and then the next control (album photo) slides on in its place.
I am not asking for you to code me this, but I am having trouble wrapping my head around a way that this could be done.
The control content is always changing, when you swipe one way, an image is removed from the view and then the next is added.
What you need is FlipView control which can get you the interface you described.
