Test Project from Customer

We have a report of an issue related to columns in GridView. This is related to case https://xamarin.desk.com/agent/case/88195

This occurred after encountering this bug with the same customer: https://bugzilla.xamarin.com/show_bug.cgi?id=22950
This link is for versioning information and the sake of organization only. The bugs are not related.

Sample provided by customer is attached. Android and iOS do not match screenshot provided. We assume the WinPhone version was the only version changed. If this is not the case, we will request an updated sample.

## Customer report 

Screenshots sent by the customer are attached in zip file.

Customer didn't test in iOS, but it mirrors what I see in Android. I have been unable to test in WinPhone. Proposed issues:

1. When type is GridLength.Auto or Star the "value" should be ignored but when I put 0 I get an exception.
Width = new GridLength(0, GridUnitType.Auto)

2. With the code below, the customer expects the image named "expected". Instead, he sees the image named "actual". He wants to put all three labels in the right corner, and his goal is the image "goal". All three images are in the Screencaps.zip file.

## Associated code:

class FrameHeader : Grid
Label dbStatus, gpsStatus, operaionStatus;

public FrameHeader()
//Padding = new Thickness(20, 0);
//HorizontalOptions = LayoutOptions.FillAndExpand;
//ColumnSpacing = 20;

RowDefinitions = new RowDefinitionCollection
new RowDefinition { Height = GridLength.Auto },
new RowDefinition { Height = GridLength.Auto },
ColumnDefinitions = new ColumnDefinitionCollection
new ColumnDefinition { Width = new GridLength(1, GridUnitType.Auto) },
new ColumnDefinition { Width = new GridLength(1, GridUnitType.Auto) },
new ColumnDefinition { Width = new GridLength(1, GridUnitType.Star) }

Children.Add(operaionStatus = new Label
Text = "Operation Status",
HorizontalOptions = LayoutOptions.Center,
Font = Font.SystemFontOfSize(24),
}, 0, 0);
Grid.SetColumnSpan(operaionStatus, 3);

Children.Add(dbStatus = new Label
Text = "DB",
//HorizontalOptions = LayoutOptions.EndAndExpand,
//Font = Font.SystemFontOfSize(24),
BackgroundColor = Color.Red
}, 0, 1);

Children.Add(gpsStatus = new Label
Text = "GPS",
//HorizontalOptions = LayoutOptions.End,
//Font = Font.SystemFontOfSize(24),
BackgroundColor = Color.Red
}, 1, 1);

Children.Add(gpsStatus = new Label
Text = "WEB",
//HorizontalOptions = LayoutOptions.End,
//Font = Font.SystemFontOfSize(24),
BackgroundColor = Color.Red
}, 2, 1);

Screencaps from customer.
Comment 2 Yuri 2014-09-18 11:36:05 UTC
I think there was a confusion as I reported 2 bugs. The screenshots are related to Grid and code in the bug is correct too but the attached project is for another bug for relative layout where Constraints are not calculated properly. Please use code in the bug but not attached project.
Comment 3 Dominic N [MSFT] 2014-09-18 11:40:51 UTC
Thank you Yuri. I have marked said project as obsolete.

If you do have a project file we can use to run tests on the issue in this report and would like to upload that here, it would be highly useful! Thanks!
