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!

 

Martijn

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.

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'
