Description

I want to remove the tree indentation in the Telerik TreeDataGrid for .NET MAUI control. This involves customizing the appearance of the ExpandCollapseIndicator to eliminate the space allocated for tree levels.

This knowledge base article also answers the following questions:

• How to control indent spacing in Telerik TreeDataGrid for .NET MAUI?

Solution

To remove the tree indentation, set the LevelIndentation property of the TreeDataGridExpandCollapseIndicatorAppearance to 0. Apply this style to the ExpandCollapseIndicatorStyle property of the TreeDataGrid.

1. Define a style for TreeDataGridExpandCollapseIndicatorAppearance in your XAML.

2. Set the LevelIndentation property value to 0.

<Style x:Key="style" TargetType="telerik:TreeDataGridExpandCollapseIndicatorAppearance">
    <Setter Property="LevelIndentation" Value="0" />
</Style>

3. Assign this style to the ExpandCollapseIndicatorStyle of the TreeDataGrid.

<telerik:RadTreeDataGrid x:Name="treeDataGrid"
                         ExpandCollapseIndicatorStyle="{StaticResource style}" />
