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

when using the justify toolbar item it does not justify the text. 

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";
}

When adding a RadCalendar with Day ViewMode in a TabView and switching tabs, null ref exception is thrown. 

Workaround: Set TabView.IsContentPreserved to True 

System.ArgumentOutOfRangeException: Count cannot be less than zero.
Parameter name: count
   at System.String.Remove(Int32 startIndex, Int32 count)
   at Telerik.XamarinForms.Input.MaskedInput.MaskParser.ConstructCandidateTextForMaskTypeRegex(String oldText, Int32 startIndex, Int32 selectionLength, String enteredText, Boolean userDeletes, Int32& insertIndex)
   at Telerik.XamarinForms.InputRenderer.UWP.MaskedInputFormsTextBox.CreateCandidateText(KeyRoutedEventArgs e, Int32& actualInsertIndex)

The issue can be reproduced in SDK Browser application MaskedInput/Features/Regex Mask example IP and email masks when enter symbol like ., @, etc.

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.

In Xamarin R1 2023 (version 2023.1.117), there's an issue which Combobox placeholder is not showing when search is enabled. Placeholder only shown when isEditable is set to false.

This issue only present in the latest version. As I've tried to downgrade to the old version and it's working fine. 

Please fix it, thanks.

I have a Xamarin.Forms app, but I only am using it for UWP at the moment. The plan is to have Android and iOS later, but I am having issues with the RadNumericInput (Xamarin.Forms) and how the decimal key is handled.

Here is my XAML

<tkInput:RadNumericInput Grid.Row="4" Grid.Column="1" Value="{Binding Price, Mode=TwoWay}" StringFormat="{}{0:C2}" />

Right now, "Price" will default to 0. The UI will initially show $0.00 because of the StringFormat. That is working fine. When I put focus into the control, I only see 0, that is also fine. The issue is when I try to type a decimal. The value disappears and I see an issue in my Output that says -- Binding: can not be converted to type 'System.Int32'

Example steps:

• With the value set to 0.00
• Focus the control -- you will now see just 0
• Press the decimal key (aka the period key)
• Notice the error in the Output window in VS and also the control shows nothing at all
• If you press the decimal key again, you will see two decimals in the control

**** Also, the Version of the Telerik controls I am using is -- 2019.2.603.360. The drop down below doesn't let me choose that version.

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.
