Description John Miller [MSFT] 2014-07-16 18:16:06 UTC
### Overview: 

    I have a ScrollView that has its Content set to a Grid that I am dynamically populating it's rows after loading the page's data. On Android the ScrollView behaves correctly, on iOS, the Grid renders outside of the bounds of the ScrollView.

### Steps to Reproduce: 

    Attached (private) is sample code for a page that replicates the issue.

### Actual Results: 

    Attached are two images showing the results on iOS vs Android.

### Expected Results: 

    The content would render the same on both platforms, inside the scrollview.

### Build Date & Platform: 

    XF 1.2.1

It is now showing the same behavior in Android (and no longer in iOS oddly enough).
Comment 5 Eric Grover 2014-08-07 15:54:28 UTC
The problem is definitely a result of dynamically adding controls to the scrollview dynamically after loading data.
Comment 8 John Miller [MSFT] 2014-08-12 17:27:10 UTC
Possible workaround:

Set IsClippedToBounds = true after binding data to the controls in the ScrollView.

We have tried to reproduce this issue by following the steps mentioned in comment 7 and observed that for android this is working fine. But when we try to check this issue for iOS, we are getting an error and when we clicked on 'Continue Execution' button, screen gets loaded for few seconds and observed that scroll view is not clipped inside the gray rectangle.

Comment 10 Eric Grover 2014-08-21 09:10:45 UTC
I am not seeing this issue currently in iOS.  The problem does occur (without the IsClippedToBounds = true workaround) on Android in the latest stable  build, and when I tried the 1.2.3 pre-release 1, the IsClippedToBounds workaround no longer works.

BTW, I have not tried running the app in Xamarin Studio, I work in Visual Studio via the build host on the mac, so I don't know if that is the reason you are seeing the error that I am not.

This should be resolved
