Hello,

I'd been testing the trial version of the Telerik chart control for Xamarin in an Android app. Because it was working well, I'd purchased a license yesterday. And, I replaced the NuGet trial package with the license package. So far, so good.

However, now, when I try to build the project, it fails. (I've tried building both the Release and Debug version.)

The errors I see are below:

Severity Code Description Project File Line Suppression State
Error failed linking references. Ble.Client.Android
Error resource style/MainTheme.Base (aka com.companyname.ble.client:style/MainTheme.Base) not found. Ble.Client.Android
ErrorNU1301       Failed to retrieve information about 'Xamarin.AndroidX.AppCompat' from remote source 'https://packagesource/FindPackagesById()?id='Xamarin.AndroidX.AppCompat'&semVerLevel=2.0.0'. Ble.Client.Android D:\2023_devwork\BLE_Xamarin\XamarinBleCodeBehind-main\XamarinBleCodeBehind-main\Ble.Client\Ble.Client.Android\Ble.Client.Android.csproj 1

Any thoughts as to what might have broken, and, what I need to do in order to resolve the issue? (In case it helps, I'm including a screen capture of the Visual Studio 2022 output window.)

Thanks!

The scrollbar on UWP is blocking the content (including the options button which is also not clickable because of it

Workaround: Add a style for the column header and apply margin to the Options button:

 

 

 

 

Some cultures have Monday as a first day of week. When device language and culture change, the RadCalendar first day of week remains Sunday, not Monday. 
There is an inconsistence in the behavior. Android Calendar changes the day to Monday. iOS not. 

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. 

Telerik.UI.for.Xamarin NuGet package is missing Telerik.UI.for.Xamarin.Documents.Fixed.FormatProviders.Image.Skia package reference.

The value of DisplayedTextFontSize is not respected when DisplayedTextFont is set on iOS.

For SelectionMode = Miultiple, we need SelectedItems property to be bound to the VM collection to get the selection items, however, when i am using the control, I am not able to find SelectedItems property for RadComboBox. Am i missing something?

Unable to deploy Xamarin app with Telerik Document Processing dlls when AOT is true in Release configuration.

An error with text like is displayed in Visual Studio:

XABLD7028: System.IO.FileNotFoundException: Could not find file '...\....Droid\obj\Release\120\aot\armeabi-v7a\libaot-Telerik.Documents.Fixed.dll.so'

 

DataBindingComplete event of the DataGrid should be fired when the associated data (ItemsSource) has been successfully bound to the control or any data operation like Group, Sort or Filter is applied.  Currently the event handler is not called as expected.

 

LongPress is called on element that is already disposed. 

ObjectDisposedException is thrown:

at Telerik.XamarinForms.Common.NativeGestureRecognizer.ToDip
 at Telerik.XamarinForms.Common.GestureListener.OnLongPress

Stack-Trace

 

The issue occurs on the following device:

Android: 12
Manufacturer: samsung
Model: SM-G970U

With the Telerik UI for Xamarin release 2022.1.222.1 SkiaSharp version was updated to 2.80.3 
but inside the Telerik.UI.for.Xamarin.SkiaSharp NuGet package the SkiaSharp.Views.Forms version is not updated. The version is 1.68.0

TimePicker allows you to create custom Accept and Cancel commands, still, currently there isn't a way to bind a command parameter and then use it in the corresponding command Execute method.

Hi Team,

Were are using RadCalendar- Agenda View mode.

In that

a)we have to add an icon in some specific appointments. 
b)We also need a clicked event on that icon  to show a TOOL-TIP with some details in it. 

Have attached a snapshot for your reference.

Please let it know the possibilities

 

Thanks,

Vinu Priya

 

Please refer to this issue: https://feedback.telerik.com/xamarin/1509502-errors-with-latest-versions-of-androidx

Hello this problem seems to be still prevalent in "Release" mode when using the individual libraries as well, in my case I am referencing the lite libraries from telerik nuget (Telerik.UI.for.Xamarin.Input.Lite + Telerik.UI.for.Xamarin.DataControls.Lite 2021.3.915.1).

There are no error when the workaround for this is to set Linking to "None". Project is latest XF 5.0.0.2196 with all latest AndroidX libraries: Project targets Android 10 (Q)

Combobox, selection mode multiple.

Select the third item:

 

And you get this:

(also note the +1 circle going over the border)

 

However, set selected items programatically, and you get this:

There's plenty of space in the control.

Open the dropdown:

Still plenty of space, but... the button has disappeared.

Collapse it by clicking somewhere outside the control and you get back to the measurement bug:

I see there are Tokens inside of the AutoComplete but standalone options would be great to have in the Telerik UI for Xamarin suite

The app crashes randomly when scrolling through the images loaded from the tagit app. 
The crash occurs on iPhone SE 2020 iOS 14.8, it doesn't crash every time you scroll through the images, the crash appears randomly.  

crash on iPhone X iOS 14.8

The issue cannot be reproduced on iPhone 12 ProMax iOS 14.8.

Hi Team,

Is it possible to show the "Current Time(Red Line)- indicator" in RadCalendar. We have attached the sample image for your reference. 

Thanks,

Vinu.
