You can find a more in-depth example by taking a look at the SDKExamples apps. Find them at the following location on the PC you installed UI for Xamarin on:
C:\Program Files (x86)\Telerik\UI for Xamarin R1 2017\Examples
Here's a screenshot of the folder:
Specifically, you want to open the XamarinForms solution.
Once it's open, take a look at the SDKBrowser (Portable) > Examples > DataForm > Editors
There are also many other demos in there such as GroupLayouts
(where you can find the GridLayout which should give you the alignment you're looking for).
Here's a screenshot to help you find it quickly.
If you have any further questions after implementing it, please reply back with the problematic code so that we can debug directly.
