When you add Telerik .NET MAUI controls that use icons, such as ComboBox, AutoComplete, etc, there are font-related exceptions in the output.

Although the exceptions do not affect the behavior and appearance of the controls, they make the output hard to read.

If a RadComboBox is used as an ItemTemplate for a ListView or CollectionView on MacCatalyst, the application crashes every time you attempt to open the dropdown with the following exception:

System.InvalidOperationException: Event registration is overwriting existing delegate. Either just use events or your own delegate: Microsoft.Maui.Controls.Handlers.Items.ReorderableItemsViewDelegator`2[Microsoft.Maui.Controls.ReorderableItemsView,Microsoft.Maui.Controls.Handlers.Items.ReorderableItemsViewController`1[Microsoft.Maui.Controls.ReorderableItemsView]] UIKit.UIScrollView+_UIScrollViewDelegate

If we have a TreeView control inside a Popup, and the TreeView is operated with a finger, everything works perfectly.
However, if there is interaction with the treeview items with a stylus (Samsung Galaxy Tab S6), the app crashes regularly.

when adding a RadButton in a Vertical Stack and the button has icon by using the font image source, the icon and button are not displayed. If you add height to the button, then it works.

Workaround:

1) Set the icon directly to the Button Text

2) Keep the font image source but set a height to the button

3) Use MAUI button.

Release 6.5.0
After dynamically setting SelectedItems on a multi select RadComboBox, it renders out all the items instead of showing the collapsed tokens view.  I believe this is because RadComboBox.HideTokens is not getting called in this situation.

Since migrating to MAUI .NET8 GA 8.0.3 (and Telerik 6.5) - on iOS the RadListView keeps repeatedly triggering the defined LoadOnDemand command to get more items even though list has not been scrolled by user. 

the behavior is valid for the command, event and collection and when automatic load on demand mode is used. 

 

When using manual mode, it works as expected.

For desktop users, it would be great if the Entry field of the Date/DateTime/Time Picker (which is currently readonly) had a MaskedInput mode so they can enter the date directly with the keyboard

If a "long" placeholder value is set when the user selects a few of the items from the multi-select combobox and taps off of the combobox, the combobox is left displaying extra whitespace below.

I tested Android and iOS only. Other platforms i cannot test at the moment.

 

Given the following implementation of the Combobox i observ different behaviour if the bound item is a enum or a class.

<telerik:RadComboBox x:Name="a"
                     ItemsSource="{Binding CloudProviders}"
                     SelectedItem="{Binding SelectedCloudProvider}"
                     IsClearButtonVisible="False">
    <telerik:RadComboBox.ItemTemplate>
        <DataTemplate>
            <Grid HeightRequest="40"
                  Padding="10">
                <Label Text="{Binding Title}"
                       TextColor="{DynamicResource DisabledTextColor}"
                       FontSize="14" />
            </Grid>
        </DataTemplate>
    </telerik:RadComboBox.ItemTemplate>
    <telerik:RadComboBox.SelectedItemTemplate>
        <DataTemplate>
            <Grid HeightRequest="40"
                  Padding="10">
                <Label Text="{Binding Title}"
                       TextColor="{DynamicResource DisabledTextColor}"
                       FontSize="14" />
            </Grid>
        </DataTemplate>
    </telerik:RadComboBox.SelectedItemTemplate>
</telerik:RadComboBox>

 

If the Itemssource is a Array of a enum type it works as intended.

If the Itemssource is a Array of classes the initial selected display member is not visible. The moment i tap into the closed combobox, the selected member is visible.

 

The attached screenshots show the page after loading and after touching into the white area(combobox) once.

 

For Localization and more details, we want to use classes. Is this a bug or do we have a issue in our code here?

The iOS app loads a long time when the "IsItemsReorderEnabled" property is set to true and the screen orientation is changed while staying on the page.

When updating to .net8 the following snippet doesn't work with target net8 (maui 8.0.3). Same works with net7 (up to 7.101).
Stops me from targeting net8.


<telerik:RadListView.FooterTemplate>
    <DataTemplate>
        <Grid
            BackgroundColor="{AppThemeBinding Dark={StaticResource ListElementColorDark},
                                              Light={StaticResource ListElementColorLight}}"
            IsVisible="{Binding CanSearchMore}">
            <telerik:RadBorder Padding="8,10" Style="{StaticResource ListItemContainer}">
                <Label HorizontalOptions="Start" Text="{Binding SearchMoreText}" />
            </telerik:RadBorder>
            <Grid.GestureRecognizers>
                <TapGestureRecognizer Command="{Binding SearchMoreCommand}" />
            </Grid.GestureRecognizers>
        </Grid>
    </DataTemplate>
</telerik:RadListView.FooterTemplate>

1. TapGestureRecognizer: Command is not executed / Click not detected
2. Style: Having a PointerOver in "ListItemContainer" works with net7. Doesn't work with net8

When programatically trying to add an item to RadComboBox.SelectedItems (in multiple selection mode) similar to this answer, we get an ArgumentOutOfRangeException on iOS.  It works fine on Android.

The stack trace is strange:

Currently the exposed by DataForm Validate/Commit and Cancel commands can be used to initiate the corresponding actions from an external UI. Make bindable commands that can be executed from the ViewModel.

Currently Telerik MAUI controls doesn't seem to support Light and Dark Themes(Modes). It will be really helpful to have this feature built in the controls or through styles supported by those controls so that these controls blend in nicely with the Light and Dark Themes supported by the app.

There would be a blank space on the left side of DataGrid when the user keeps double clicking (editing) on different cells quickly.
