Dynamic grid-ish Flow-Layout using LayoutGroupControl and GroupControl

I am about to write a main menu for a Windows Forms application.
Rather than trying to explain my goal with a wall of text i made a quick(ugly) paint sketch:
As you can see here i want the Group Controls to automatically scale with their content(similar to the wrap_content attribute in android) and fit underneath each other if possible.
If anyone knows how to achieve this or even has a sample where he already did achieve it, that would help me massively!
thanks, Felix.

Border radius on Entry Xamarin Forms PCL

Is there a way to set a border radius on an Entry in Xamarin's XAML, or by using a custom renderer or something ?
Everything I've tried up to now has no effect, but for my application it would be really better if I had round borders.
Thank you in advance for your answer !
PS : I've checked this post but I've not found my answer there :)

I've posted this answer here too, but for convenience I'll just paste it below:
I'm not sure if there's something wrong with this approach or not, because it seems so simple but no one's suggesting it.
But I don't see why you can't just use a Frame with IsClippedToBounds set to true. That gives you a built-in corner radius, which you can then adjust as needed.
<Grid>
<Frame
CornerRadius ="20"
IsClippedToBounds="true">
<Editor />
</Frame>
</Grid>
I'm currently using this solution and it works for me.

I think you can use a grid with 1 row and 1 column
Inside the grid you can add your Entry and, for example, this control, in the same (the only) cell. You should have an Entry with rounded corners...
This is another useful control (XFShape). Create shapes content views from shared code for your mobile apps! For Android and iOS.

How would you create stackable rectangles in Xamarin C# for iOS?

I have a UIView that I want to fill with multiple rectangles stacked on top of each other horizontally at 100% width. They all need to have their own name and need to work for any iOS device regardless of size.
Here's a simple diagram showing what I would like to accomplish:

With Xamarin.Forms, this is achieved by using a StackLayout.

I find it difficult to control the exact sizes of StackLayouts if you're not sure of the size of your content.
If i need something to stay fixed size, i use Grids:

I would recommend XibFree for this:

They have a few great examples which covers these case as well:
