Use the following steps to customize or hide the expand icon in the .NET MAUI CollectionView when grouping is enabled.

• Customize the Expand Icon in .NET MAUI CollectionView Grouping
• Hide the Expand Icon in .NET MAUI CollectionView Grouping

Customize the Expand Icon

To use a custom expand icon in the .NET MAUI CollectionView when grouping is enabled, you have to use the GroupViewStyle property:

XAML

<telerik:RadCollectionView>
    <telerik:RadCollectionView.GroupViewStyle>
        <Style TargetType="telerik:RadCollectionViewGroupView">
            <Setter Property="ExpandCollapseIndicatorStyle" Value="{StaticResource ExpandCollapseIndicatorStyle}" />
        </Style>
    </telerik:RadCollectionView.GroupViewStyle>
</telerik:RadCollectionView>

Define the ExpandCollapseIndicatorStyle style to customize the expand icon. You can set a custom icon or change the text color, for example:

XAML

<ContentPage.Resources>
    <ResourceDictionary>
        <Style x:Key="ExpandCollapseIndicatorStyle" TargetType="Label">
            <Setter Property="TextColor" Value="Red" />
        </Style>
    </ResourceDictionary>
</ContentPage.Resources>

Hide the Expand Icon

To hide the expand icon set the IsVisible property of the expand indicator to False in the ExpandCollapseIndicatorStyle:

XAML

<ContentPage.Resources>
    <ResourceDictionary>
        <Style x:Key="ExpandCollapseIndicatorStyle" TargetType="Label">
            <Setter Property="TextColor" Value="Black" />
            <Setter Property="IsVisible" Value="False" />
        </Style>
    </ResourceDictionary>
</ContentPage.Resources>

Then set the ExpandCollapseIndicatorStyle to the GroupViewStyle of the CollectionView as shown below:

XAML

<telerik:RadCollectionView>
    <telerik:RadCollectionView.GroupViewStyle>
        <Style TargetType="telerik:RadCollectionViewGroupView">
            <Setter Property="ExpandCollapseIndicatorStyle" Value="{StaticResource ExpandCollapseIndicatorStyle}" />
        </Style>
    </telerik:RadCollectionView.GroupViewStyle>
</telerik:RadCollectionView>
