RadComboBox is not selecting value from dropdown in IOS, when the TabGesturerecognizer is for keyboard added in AppDeligate.

Hi Team,

There is an issue we are facing only in IOS, where when trying select any value from RadComboBox dropdown it don't get selected.

This issue only occurs when we have the below code added in AppDeligate, which is for hiding the keyboard when clicked anywhere outside of the UI:

 

NOTE: the gesture code we need in our app.

Attaching the sample project as well.

 

Thanks & Best Regards,

Mohammed Rameez Raza.

     Padding="0"
     BackgroundColor="Blue"
     TicksPlacement="None"
     TickStep="10"
     SnapMode="SnapToTicks"
     LabelsPlacement="End"
     LabelStep="10"
     StringConverter="{x:Static converters:PetDistanceStringConverter.I}"
     Minimum="0"
     Maximum="100"
     Value="{Binding Distance, Mode=TwoWay, Converter={x:Static converters:IntToDoubleConverter.I}}"

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.

[Solved] 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?
