the following exceptions occur when upgrading to Xamarin.Forms v 4.0:
System.NotSupportedException: Unable to activate instance of type Telerik.XamarinForms.DataControlsRenderer.Android.ListView.TemplateCellContainer
System.NullReferenceException: Object reference not set to an instance of an object
at Telerik.XamarinForms.InputRenderer.iOS.SegmentedControlRenderer.OnElementDetached
UPDATE:
The issue is confirmed to be in Xamarin.Forms framework. A fix is already provided. The Xamarin.Forms 4.3 version will contain the fix.
Hi there,
We're struggeling with the radentry control. For login purposes we use one for the password and one for the email. When we set IsPassword=true this does show dots instead of words, but some basic stuff isn't working.
1) The normal entry with IsPassword=true does also hide the suggestion tab that is above the keyboard. We also tried hiding this with other settings but to no result. This control should also hide suggestions since it is a password and we don't want to cache this in any way.
2) When we replace the radentry password field with a xamarin entry password field (so set IsPassword=true on both) then we also get the password fill option. In this case Samsung keypass. I imagine if people are using autofillers such as samsung, google, or something else, that this should also work since i'm stating the field is a password field.
Tested on android with multiple devices.
Thanks in advance!

When the SelectionMode of the RadCalendar is Range and you have set a MaxDate - you should not be able to select dates after the MaxDate. However, swipe-selecting cells which are disabled is working. Available in the R3 2018 SP release.
When there are only two items in the ItemsSource and users reorder them, the underlying collection is not reordered Edit: Avalable in R3 2017 SP release.
This can be reproduced using an image with binding for its source.
If the source data has only zero values initially, when the values are changed, the chart does not update its axis range. Available in minor release 2017.3.927. It will also be available in the R3 2017 SP release.
Available in the R3 2017 release.
I met an issue related to Xamarin.Forms RadListView (telerik component) which occurs only on iOS platform, while working fine on Android. More details here - http://www.telerik.com/forums/radlistview-not-fitting-on-ios
Multiple selected items that were selected become unselected when being filtered out. Steps to reproduce: 1 - Select multiple items 2 - Apply filter where some or all of the selected items are filtered out 3 - Remove filter Observe: 1 - The items that were previously selected have lost their selection state after returning 2 - Items that were not filtered, or selected while filter was active, retain selection state
When Maximizing and Restoring the application's window, the RadSideDrawer's MainContent sometime gets measured wrong. This results in a corrupt state where all the main content is off-screen when the app is in the Restored state.
This can be tricky to reproduce without guidance, therefore I've recorded a video (attached) to demonstrate how to reproduce it as fast as possible with the code below:
<ContentPage ...> <telerikPrimitives:RadSideDrawer DrawerLength="400" AreGesturesEnabled="false" DrawerLocation="Bottom" DrawerTransitionType="SlideInOnTop" DrawerTransitionDuration="0.2" IsOpen="False" VerticalOptions="FillAndExpand"> <telerikPrimitives:RadSideDrawer.DrawerContent> <StackLayout VerticalOptions="FillAndExpand" BackgroundColor="GreenYellow"> <Label Text="DrawerContent" VerticalOptions="FillAndExpand"/> </StackLayout> </telerikPrimitives:RadSideDrawer.DrawerContent> <telerikPrimitives:RadSideDrawer.MainContent> <StackLayout Orientation="Vertical" VerticalOptions="FillAndExpand" BackgroundColor="LightBlue" Margin="0" Padding="10"> <Button Text="Telerik" FontSize="Large" BackgroundColor="Orange" HorizontalOptions="FillAndExpand" /> </StackLayout> </telerikPrimitives:RadSideDrawer.MainContent> </telerikPrimitives:RadSideDrawer></ContentPage>
There are 2 approaches to customize the theme -> directly override the resources in the BlueResources dictionary or create a custom resource dictionary and merge it instead of the BlueResources one. If you take the first approach in a .NET standard project and override one of the colors -> an ArgumentException is thrown: Use the second approach as a workaround where you create a custom resource dictionary, copy all the colors from the original one and modify them within your custom one. Available in the R3 2018 SP release.
We have a RadCalendar and we set the CalendarViewMode to "Year". And we tap on an arbitrary month in order to open it (change the ViewMode to "Month"). EXPECTED result: The selected (tapped) month is opened, i.e. the ViewMode is changed to "Month". And this is happening on Android. ACTUAL result: On iOS the result is this exception: System.InvalidCastException: Unable to cast object of type 'TelerikUI.TKCalendarYearPresenter' to type 'UIKit.UIView'
Item tapped is raised after hold gesture in IOS listview. The control should recognize a hold gesture is initiated and item tapped event should not be raised.
Available in minor release 2017.3.927. It will also be available in the R3 2017 SP release.
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.
