Description Jon Goldberger [MSFT] 2014-10-03 15:14:46 UTC
## Description

In a Forms ContentPage whose content is a RelativeLayout that includes some controls, though all of the controls are rendered properly using the default page renderer, if using a custom page renderer controls that do not set the size explicitly do not render. Tested this on Forms versions and

## Steps to reproduce

1. Open the attached test project and restore packages.
2. Launch the iOS project to a simulator or device.

## Expected result

Page that shows should have two labels and a button.

## Actual result

Page only displays one label and a button.

## Further test to confirm that second label is rendered using the default page renderer

3. In the App.cs file of the Forms project, change:

return new RightSideMenuPage();


return new MainPage();

4. Launch iOS app.

## Expected result

Page shows with two labels and a button.

## Actual result

As expected.

## Notes 

Look in MainPage.cs of the Forms project and note that for the second Label, only the x and y values are given. This is the Label that is not rendering using the custom page renderer, but does using the default renderer.
