I need to create a picker which have 2 columns in xamarin forms like timepicker. I am using Picker control. Is there any way through which we can make multiple columns in Picker?
We've developed a two-column picker for Xamarin.Forms (Android and iOS).
Sample:
https://github.com/HorusSoftwareUY/MaterialDesignControlsPlugin#materialdoublepicker
Screenshots:
Android
iOS
We added this control to MaterialDesignControls NuGet (https://www.nuget.org/packages/Plugin.MaterialDesignControls/), where you can find other interesting controls with the material design look and feel.
Contributions are welcome!
Try Syncfusion Cascading control for Xamarin, they are free if your company earn less than $1 million dollar in revenue.

I need to design bottom navigation bar like I attached image using xamarin.forms common code for both android and IOS. Can anybody refer any link or library tool to do this?
You should check the xamarin community toolkit, this is certainly possible to create with the tabview.

Is there a way to define a Label in Xamarin Forms (XAML or code-behind) AppXYZ that can be updated from the Xamarin Android AppXYZ.Android: MainActivity.cs and AppXYZ.iOS:Main.cs? i.e. upon an event in Android (e.g. BlueTooth) set a short text in a common Forms elements? After viewing many example, no clarity yet. MessageCenter perhaps?
In Android Project: MainActivity.cs (for example):
FormsAppXYZ.LabelXYZ.Text = "Updated string";
If not possible, then proper way to do this with Xamarin Android Native ? appreciated since I'll have to mix in the label into a shared Xamarin Forms Tabbed GUI.
Depending on how much Bluetooth work you need to do, my first suggestion would be to use MessagingCenter as you have already alluded to.
The other obvious approach would be to use a third party plugin, as I don't believe Xamarin have released one. I am currently aware of these two:

There are good numbers of post of this but not of them are simple one. One of them is below one which is look simple https://developer.xamarin.com/recipes/ios/content_controls/navigation_controller/add_a_nav_bar_bottom_toolbar/
I am new to xamarin and currently using xamarin form to develope an cross plate form app. It looks above example is using xamarin native not xamarin form? Can same example will work for xamarin form? Or for this kind of UI manipulation xamarin native is better than xamarin form. As i am new to xamarin, should i focus on xamarin native instead of xamarin form for serious app development.
Thanks,

Please click here for Bottom Navigation Bar for Xamarin Forms.
This will look like below:
You could build it on your own with a ControlTemplate.
No CustomRenderer is needed.

We are trying to present territory map view with different controls in android and iOS platform using xamarin.forms or Xamarin Native. Is there any map control avaialble to present territory map view in xamarin forms?
It looks like Syncfusion has something similar to what you want in their Maps
Is it possible to mix iOS Storyboards and Xamarin Forms within one application? I have a bunch of views that are easier to be created in Forms, but some which are heavily customized so we would need to create some of them in native code.
I would like to use Storyboards to create the native parts, but can't seem to find a way to navigate from a Forms page to a Storyboard and vice versa.
I don't mind doing it from code, just need to know the direction to look into and if it's even possible.
You can create native views using the concept of Custom Renderers (see links below). The idea is that you create a Xamarin Forms Control that's shared between all platforms and which old common properties (like colors, general data etc), and do the native rendering on the iOS/Android/WP projects.
So, for your storyboard, you can create it usign Xamarin.iOS, and render using a Custom Renderer. The link posted by #GSerg in the comments have some information and examples, but you can take a closer look at the oficial documentation as well:
Introduction to Custom Renderers
Customizing Controls on Each Platform
Customizing Control Rendering in Xamarin.Forms (video)
Also, for more real world examples you can take a look at the Xamarin Forms XLabs project.
Thanks to Rafael Steil's answer. I looked at the links and a few more samples.
Notably:
Custom Renderer Map
Using Xamarin Forms alongside Storyboard
And I created a sample project to show the back-and-forth navigation between Xamarin Forms and pages created in Storyboards. You can find it over here:
