Hello,

With the 2022.2.606 LIB version (from 6 Jun 2022), a HighlightedBackground property has been introduced for the GridViewCell element. From this version onwards, the highlighted search results of the GridView can be modified through the HighlightTextBlock's HighlightBrush (foreground) and the cell's HighlightedBackground (background). This can be achieved through two implicit styles for example:

<telerik:RadGridView x:Name="gridView" ShowSearchPanel="True" ItemsSource="12345">
    <telerik:RadGridView.Resources>
        <Style TargetType="telerik:GridViewCell" BasedOn="{StaticResource GridViewCellStyle}">
            <Setter Property="HighlightedBackground" Value="Purple"/>
        </Style>
        <Style TargetType="telerik:HighlightTextBlock" BasedOn="{StaticResource HighlightTextBlockStyle}">
            <Setter Property="HighlightBrush" Value="Lime"/>
        </Style>
    </telerik:RadGridView.Resources>
</telerik:RadGridView>

The BasedOn in the above styles is needed only for the NoXaml version of the assemblies. They can also be defined on app level (App.xaml).

Best Regards,
