When the Telerik Xamarin toolbox is in a partial-height tab (i.e. half the height), there isn't a scrollbar to see the off-screen controls.

Workaround: 
Make the toolbox full height of the tab to see all the controls. Here's a video demonstrating https://www.screencast.com/t/cUjIC0sx4

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:

    <ContentPage.Resources>
        <ResourceDictionary>

            <telerikGrid:DataGridColumnHeaderStyle x:Key="headerstyle"
                                           TextColor="Black" OptionsButtonMargin="0,0,20,0" 
                                                   OptionsButtonFontSize="30"
                                           BorderColor="Black" 
                                           BorderThickness="2"/>
        </ResourceDictionary>
    </ContentPage.Resources>
    <Grid>
        <telerikGrid:RadDataGrid ItemsSource="{Binding Items}" BackgroundColor="Red" AutoGenerateColumns="false">
            <telerikGrid:RadDataGrid.Columns>
                <telerikGrid:DataGridTextColumn PropertyName="Country" HeaderStyle="{StaticResource headerstyle}"/>
                <telerikGrid:DataGridTextColumn PropertyName="Capital" HeaderStyle="{StaticResource headerstyle}"/>
            </telerikGrid:RadDataGrid.Columns>
        </telerikGrid:RadDataGrid>
    </Grid>

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.

Do you have plans to develop controls for the UNO platform?

 

There are other companies that have already stated that they are working on it, for example,

Release R1 2021 SP1

When building against XF5 and after migrating a project you can get the following error:-

Severity Code Description Project File Line Suppression State
Error failed linking file resources. App1.Android
Error '5dp' is incompatible with attribute verticalOffset (attr) float [weak]. App1.Android
Error '10dp' is incompatible with attribute horizontalOffset (attr) float [weak]. App1.Android

It appears to be a conflict between

<PackageReferenceInclude="Xamarin.Google.Android.Material"Version="1.2.1.1" />

and Telerik assemblies.

If a dummy app is built with that Nuget it all works fine until the Nuget

<PackageReference Include="Telerik.UI.for.Xamarin" Version="2021.1.119.1" />

is added.

So you can have one or the other but not both.

Please see this GitHub thread where its discussed more and a sample app is posted.

(I am user Gmotagi in it)

RdBusyIndicator BusyContent data binding does not work. If a string constant is assigned to the     

 

     <telerik:RadBusyIndicator
                HorizontalOptions="FillAndExpand"
                VerticalOptions="FillAndExpand"
                IsBusy="{Binding IsBusy}"
                IsVisible="{Binding IsBusy}"
                AnimationContentHeightRequest="60"
                AnimationContentWidthRequest="60"
                AnimationType="Animation3"
                AnimationContentColor="{DynamicResource BrandPrimaryColor}">
                <telerik:RadBusyIndicator.BusyContent>
                    <Label Text="{Binding BusyContent}" HorizontalOptions="Center"/>
                </telerik:RadBusyIndicator.BusyContent>
      </telerik:RadBusyIndicator>

 

RdBusyIndicator BusyContent data binding does not work for the above Label inside the "telerik:RadBusyIndicator.BusyContent". If a string constant is assigned to the Text(for example "Loading..."), then it works perfectly.

The view model 100% has the property "BusyContent" with a value. By the way, the IsBusy and IsVisible data binding work fine.
