We are only using the Rad ListView, so have only needed the Lite package but it requires the SkiaSharp package as well. It seems that Map, ImageEditor, PdfViewer and DataGrid controls are added in the lite nuget package.

We have yet to upgrade our mobile app to Xamarin Forms 4.x and the latest Telerik releases due to a hard crash in Android when we leave a page containing a Telerik ListView control.   

The exception seems to mirror what is discussed here:  https://www.telerik.com/forums/null-ref-error-iorderedtraversalcontroller-updatetraversalorder

Here is what we are seeing... what is the latest on addressing this error?   We need to upgrade from Xamarin Forms 3.6.x soon.

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.

System.NullReferenceException is thrown when navigating back pages with RadListView and using Xamarin.Forms 4.0 or higher. 

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!

As the subject:

Before upgrading to the latest version of Telerik Controls, the Drag/Drop functionality worked correctly but after upgrading the list no longer updates and the item moved returns back to the original position.

Not using "ReorderEnded", everything works fine but this is needed to detect that something has been moved.

We can build on our personal development environments without issue. The issue is only on the Azure DevOps build server. We believe this to be related to a version incompatibility. Possibly the build server is attempting to reference an old library. We are seeing the issue on both iOS and Android builds. 

This issue is well documented here: 
https://www.telerik.com/forums/can%27t-resolve-the-reference-%27system-object#wNK1sRy19UOhttFJzbEshQ

Our version info:
- Build server is using  Microsoft's hosted agent with Visual Studio for Mac 7.7.4.1 (attached file with all software installed on the host build-host-software.txt)
- App is on version 3.4.0+
- Referenced libraries use .NET Standard 1.6 and 2.0
- Xamarin.Forms app is hosted in a .NET Standard 2.0 library

Could we get a hold of an older compatible version of the software that can work with our version if there is no workable solution here ?

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>
