Breaking Changes in Version 13.0.0

Updated on Feb 16, 2026

This article lists the breaking changes introduced with the Telerik UI for .NET MAUI 13.0.0 release version.

Common

The KeyboardInfo class is moved from the Telerik.Maui.Controls assembly to the Telerik.Maui.Core assembly.

Chat

There are changes in the Chat control template.

The RadChatListView now inherits from RadCollectionView.

The input control used in the Chat is now the RadPromptInput.

If you override the default control template you have to use the following template:

XAML

<ControlTemplate x:Key="RadChatControlTemplate">
    <Grid x:Name="PART_RootGrid"
            IsClippedToBounds="True">
        <Grid telerikMauiControls:KeyboardHelper.IsTranslationTarget="True"
                IsClippedToBounds="True"
                RowSpacing="2"
                RowDefinitions="*, Auto">
            <Grid RowDefinitions="*, Auto"
                    Margin="{OnPlatform Default=10, MacCatalyst='0, 10', WinUI='0, 10'}">
                <telerikChat:RadChatListView x:Name="PART_ChatListView"
                                                telerikMauiControls:StyleHelper.InheritedStyleClass="{TemplateBinding ActualStyleClass}"

            </Grid>
        </Grid>
    </Grid>
</ControlTemplate>

The part elements must be included inside the custom template you use: PART_ChatListView, PART_PromptInput.

Do not remove the x:Name of the control's definitions inside the control template.
