Crash in MAUI Android .NET 9 Telerik MAUI 8.0.0

Hi,

Just updated to .NET 9 and Telerik MAUI 8.0.0.

Getting a crash when using a RadDataGrid on android 5.1.1 (this version is supported by .NET 9). The crash was not happening on .NET 8 and Telerik MAUI 7.0.0.

        <telerik:RadDataGrid x:Name="dataGrid" ItemsSource="{Binding Items}" AutoGenerateColumns="False">

            <telerik:RadDataGrid.Columns>
                <telerik:DataGridTextColumn PropertyName="Name" SizeMode="Auto"/>
                <telerik:DataGridTextColumn PropertyName="Value" SizeMode="Stretch"/>
            </telerik:RadDataGrid.Columns>
            <telerik:RadDataGrid.GroupDescriptors>
                <telerik:PropertyGroupDescriptor PropertyName="Section"/>
            </telerik:RadDataGrid.GroupDescriptors>
        </telerik:RadDataGrid>

It looks like Telerik.Maui.Handlers.RadTextInputHandler.MapCustomCursorColor is trying to call to a function that does not exist in android 5.1.1.

Add FontAutoScalingEnabled for Items in .Net Maui Controls

I currently have a RadComboBox. I mainly want to use the default stylings (apart for some colors as you can see in the code), but I want to disable FontAutoScalingEnabled on every text/label items.

<telerik:RadComboBox Grid.Column="0" Grid.Row="0"
                     ItemsSource="{Binding MyItems}"
                     SelectionMode="Single"
                     Placeholder="{x:Static resx:Labels.ItemCategory}"
                     SelectedIndex="{Binding SelectedItemIndex, Mode=TwoWay}">
    <telerik:RadComboBox.Style>
        <Style TargetType="telerik:RadComboBox">
            <Setter Property="BackgroundColor" Value="{StaticResource White}"/>
            <Setter Property="TextColor" Value="{StaticResource Black}"/>
            <Style.Triggers>
                <DataTrigger Binding="{Binding SelectedItem}" Value="True" TargetType="telerik:RadComboBox">
                    <Setter Property="BackgroundColor" Value="{StaticResource Primary}"/>
                    <Setter Property="TextColor" Value="{StaticResource White}"/>
                </DataTrigger>
            </Style.Triggers>
        </Style>
    </telerik:RadComboBox.Style>
</telerik:RadComboBox>

How can I set FontAutoScalingEnabled  for all labels in the ComboBox (selectable Items and selectedItem).

 

Thanks in advance!

CollectionView Shows Extra Items in Groups with Multiple Entries

I setup a CollectionView with grouping based on an attribute of the item.  Everything seems to be working, except in the groups with more than one item there are a couple extra items in the list.  One is the name of the group, and the other is 'Grand Total'

If I click on them the Item tapped handler receives a string.  I do not see anything to turn this behavior on/off.  My setup for the RadCollectionView is pretty basic


    <telerik:RadCollectionView x:Name="RadCollectionView"
                         BackgroundColor="Transparent" VerticalOptions="Fill"
                         ItemsSource="{Binding SymbolItems}"
                         ItemViewStyle="{StaticResource SymbolItemStyle}"
                         SelectionMode="Single"
                         SelectedItem="{Binding SelectedSymbolItem}"
                         ItemTapCommand="{Binding SymbolClickedCommand}">
      
      <telerik:RadCollectionView.GroupDescriptors>
        <telerik:PropertyGroupDescriptor PropertyName="Parent" />
      </telerik:RadCollectionView.GroupDescriptors>


      <telerik:RadCollectionView.ItemTemplate>
        <DataTemplate x:DataType="edit:SymbolItem">
          <Grid ColumnDefinitions="40, *" Margin="40,0,0,0">
            <ffImage:CachedImage Grid.Column="0" Grid.Row="0" HeightRequest="60"
                                 Source="{Binding ImageSource}"/>
            <Label Grid.Row="0" Grid.Column="1"
                   VerticalOptions="Center"
                   FontAttributes="Bold"
                   FontSize="17"
                   VerticalTextAlignment="Center"
                   Margin="10,0,0,0"
                   Text="{Binding Name}"/>
          </Grid>
        </DataTemplate>
      </telerik:RadCollectionView.ItemTemplate>
    </telerik:RadCollectionView>




      <Style x:Key="SymbolItemStyle" TargetType="telerik:RadCollectionViewItemView">
        <Setter Property="VisualStateManager.VisualStateGroups">
          <VisualStateGroupList>
            <VisualStateGroup Name="CommonStates">
              <VisualState Name="Normal">
                <VisualState.Setters>
                  <Setter Property="BackgroundColor" Value="Transparent" />
                </VisualState.Setters>
              </VisualState>
              <VisualState Name="Selected">
                <VisualState.Setters>
                  <Setter Property="BackgroundColor" Value="LightGrey" />
                  <Setter Property="BorderColor" Value="#0A3A82"></Setter>
                  <Setter Property="BorderThickness" Value="2"></Setter>
                </VisualState.Setters>
              </VisualState>
            </VisualStateGroup>
          </VisualStateGroupList>
        </Setter>
      </Style>

What is required to remove these items from the view?

Thanks -Joe

Print (or share) PDFs from RadPdfViewer

Hi folks,

 

Is there any way to print a document directly from the RadPdfViewer or even share the document (e.g., iOS Share Menu) to select the system print functionality or move the document to a different place/app?

RadListView Set SelectedItem from code

I have a RadListView I am setting up to replace the standard Maui ListView.

One thing I need to do is set the Selected item in the ViewModel as part of a filter so filtered item is already selected.  This seems to be an issue with doing this in the RadListView.


<telerik:RadListView x:Name="RadListView" 
                     BackgroundColor="Transparent" VerticalOptions="Fill"
                     ItemsSource="{Binding SymbolItems}"
                     SelectionMode="Single" SelectionGesture="Tap" IsGroupHeaderSticky="True"
                     SelectedItem="{Binding SelectedSymbolItem, Mode=TwoWay}" >

I setup the SelectedItem to fire off the Notify (this uses Prism base class) 

public SymbolItem SelectedSymbolItem
{
	get => _selectedSymbolItem;
	set => SetProperty(ref _selectedSymbolItem, value);
}

But when I set the SelectedItem I get an exception

Value cannot be null. (Parameter 'indexPath')
   at ObjCRuntime.ThrowHelper.ThrowArgumentNullException(String argumentName) in /Users/builder/azdo/_work/1/s/xamarin-macios/src/ObjCRuntime/ThrowHelper.cs:line 28

   at Telerik.Maui.Controls.Compatibility.DataControls.RadListView.UpdateSelectedItem()
   at Telerik.Maui.Controls.Compatibility.DataControls.RadListView.OnPropertyChanged(String propertyName)

The value being set is definitely not null.

Also I notice that the Setter seems to be getting invoked twice, so if I put a breakpoint my code goes in and executes the setter, and then seems like the framework does something and invokes it again which throws the exception.

Can SelectedItem in a RadListView be set be using the bound property? (like with any general TwoWay binding).  If not how could this be achieved?
