Exception occurs when there are no items in the collection and load on demand mode is automatic: 

public ViewModel()
{
    this.Source = new ObservableCollection<string>();
    //for (int i = 0; i < 14; i++)
    //{
    //    this.Source.Add(string.Format("Item {0}", i));
    //}
    this.LoadItemsCommand = new Command(this.LoadItemsCommandExecute);
}

Occasionally the DataGrid horizontal scrolling does not work properly after changing its ItemsSource.  Still, tapping on any item, make it possible to scroll again.

Watermark text is not displayed on Android. 

Workaround: 

set the WatermarkText property in code-behind with some delay:

Device.BeginInvokeOnMainThread(() =>
{
    mask.WatermarkText = "enter e-mail here";
}

Bound Items to the ListPicker.ItemsSource= {B, C, D}
Open picker.

Do not scroll or tap anything, just press OK

Expected -> SelectedItem = B
Actual -> SelectedItem remains A.

Hi Team,

Currently, you have ScrollItemIntoView support. However, that does not work unless you have rows and a reference to the data item.

I need an explicit mechanism to pick a specific X/Y cell position, or at least a column index, that can be scrolled to so that I can have horizontal scrolling capability.

For example, imagine a DataGrid that has only one row, but a 100 columns, I would like to be able to do this:

// Option 1 - Use the ItemsSource column reference
var dataTableColumn = this.myDataTable.Columns[50];
this.MyDataGrid.ScrollIntoView(dataTableColumn);

// Option 2 - Better!  
// This supports any possible data source type
var telerikColumn = this.MyDataGrid.Columns[50];
this.MyDataGrid.ScrollIntoView(telerikColumn);

// Option 3 - Ideal
// Useful for every possible occasion
var x = 5;
var y = 12;
this.MyDataGrid.ScrollIntoView(x, y);

When having the following code on a button click 

private void Button_Clicked(object sender, System.EventArgs e)
{
       this.chart.Zoom = new Size();
}

The chart zoom is reset first time, but when zooming again and pressing the button, the zoom level does not reset. You have to pan the chart, then zoom reset works. 

This code resets the zoom:

private void OnResetZoomClicked(object sender, EventArgs e)
{
	this.chart.Zoom = new Size(1, 1); // This line is added as a workaround to reset the Zoom level
	this.chart.Zoom = new Size();
}

When the RadShadow is added inside the Xamarin ListView cell, and then when scrolling through the ListView, the content in the cell disappear.

Solution:
Use Telerik Xamarin RadListView control instead.

Using a DynamicResource to set the GaugeRange Color property does not work:

<!-- does not work -->
<gauges:GaugeRange Color="{DynamicResource GrayBackgroundColor}" ... />

Using a StaticResource works as expected:

<!-- works -->
<gauges:GaugeRange Color="{StaticResource GrayBackgroundColor}" ... />

Side-Note:
Using DynamicResource for Indicator Fill works as expected.

Some cultures have Monday as a first day of week. When device language and culture change, the RadCalendar first day of week remains Sunday, not Monday. 
There is an inconsistence in the behavior. Android Calendar changes the day to Monday. iOS not.

Having a ComboBox inside the RadListView ItemTemplate. 

Binding the ComboBox SelectedItems. 
On UWP when PropertyChanged is called on an item in the ListView, it fires the ComboBox SelectedItems CollectionChanged with action Remove, which is wrong behavior. And as a result the ComboBox SelectedItems collection is cleared. 

On Android an iOS works as expected, the ComboBox SelectedItems collection is not cleared.

The image editor is a great start, but missing a critical feature - image drawing / annotation. The ability to draw lines, shapes or text onto an image. Should allow this to be done when pinch / zoom is in progress. Items drawn should be amendable until saved. Opportunity to retrieve the annotation only data separately to the image so you can preserve the original.
