## Description

I want to hide the default expand/collapse icon in the .NET MAUI CollectionView when grouping is used. I plan to use a custom icon and style it further.

This knowledge base article also answers the following questions:

• How can I replace the default expand icon in .NET MAUI CollectionView with a custom one?
• How to hide the expand/collapse indicator in .NET MAUI CollectionView grouping?
• How to style the expand/collapse icon in .NET MAUI CollectionView?

Solution

To hide the default expand/collapse icon and use a custom icon, use either the GroupViewStyle property or remove the default indicator.

Option 1: Using GroupViewStyle

1. Remove the default expand arrow from the group template.
2. Use the GroupViewStyle property and its ExpandCollapseIndicatorStyle to style the expand indicator.

XAML

<telerik:RadCollectionView.GroupViewStyle>
    <telerik:GroupViewStyle ExpandCollapseIndicatorStyle="{StaticResource ExpandCollapseIndicatorStyle}" />
</telerik:RadCollectionView.GroupViewStyle>

3. Define the style with the target type Label.

XAML

<Style x:Key="ExpandCollapseIndicatorStyle" TargetType="Label">
    <Setter Property="TextColor" Value="Black" />
    <Setter Property="FontSize" Value="18" />
</Style>

Refer to the official documentation for more information on GroupViewStyle.

Option 2: Removing Default Indicator

1. Set the IsVisible property of the expand/collapse indicator to False in the style.

XAML

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

2. Define your custom indicator in the group template.

XAML

<telerik:RadCollectionView.GroupViewStyle>
    <telerik:GroupViewStyle ExpandCollapseIndicatorStyle="{StaticResource ExpandCollapseIndicatorStyle}" />
</telerik:RadCollectionView.GroupViewStyle>
