Currently, the only means to execute actions with the image editor is to use the built-in toolbar. While covering the most basic use cases, this approach limits the usage of the component in some more advanced scenarios. For this reason, it would be beneficial if some of the internals are exposed as a public API, to allow executing actions with the image editor programmatically.

I am opening this topic to collect customer feedback which features need better public exposure. When voting for a feature, please provide some details how do you intend to use it in your application, if possible, so that we can design a more intuitive and easy to use API facade for it.

If you set SelectedDate when the Calendar control is created, does not take any effect in the UI on iOS. 

As a workaround, set SelectedDate at a later stage.

Type: Bug Report

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.

Native UWP calendar in DayView/MultiDayView Mode has a property which helps you specify height between the time lines. Please provide this option for Android and iOS too.

If we have a ListView with a CheckBox inside the ItemTemplate and the whole ListView is placed in a Popup control, following the next steps:

1. Open the popup

2. Check and uncheck the CheckBox control in any of the items.

3. Click into the popup and then outside to close it.

NullReferenceException is raised on iOS.

When display is on high resolution screen (MS surface book screen 3000*2000 with 200% scale) the DataGrid is not resized correctly.  See attachments.

As an effect of this, characters, which are not contained in the StandardEncoding names, e.g. umlauts, are measured with incorrect glyph widths. This leads to incorrect glyph positioning in RadPdfViewer.

Java.Lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

For example change the IsPullToRefreshEnabled state on button click, when button is pressed several times, exception is throw.

I'm using a popup and If the device is rotated when the pop-up is open, the UI gets disorted and gets a white space on sides or becomes uneven.

Please see the attached screenshots and below code to replicate the issue. Not sure about this issue occurring on android tablets.


<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns=""

            <RowDefinition Height="*"></RowDefinition>
        <Button HorizontalOptions="Center" Grid.Row="0"
        Text="Click here to rate" 
                <telerikPrimitives:RadPopup x:Name="popup"
                    <telerikPrimitives:RadBorder CornerRadius="8" 
                        <Grid Padding="20">
                                <RowDefinition Height="30" />
                                <RowDefinition Height="20" />
                                <RowDefinition Height="40" />
                            <Label Text="Please rate your experience" />
                            <telerikInput:RadShapeRating Grid.Row="1" />
                            <Button Grid.Row="2"
                            Clicked="Button_Clicked" />

When using DataTemplates on the ListView for Android, items are constantly redrawn when data shown on the template is updated, this is obvious to the user as it flashes and doesn't look great. Note that the native ListView does not do this.

Currently, if the value contains longer text, the barcode is not expanding, just uses smaller points to accommodate it. 

In addition, the barcode does not take all the available space (with Stretch Sizing mode).
