That solves it, thanks.

Hello,

If you set the theme property of the XamDataGrid, you have to define any other styles for it in the Resources of the XamDataGrid. This is because WPF supports only one local style. Once the element finds a style by going up the element tree, it stops. This happens when using themes - the elements find their theme styles in the XamDataGrid's resouces.

You can also try to set the style based on the theme like this:

<Style TargetType="{x:Type igDP:DataRecordPresenter}" BasedOn="{x:Static Themes:DataPresenterOnyx. igDP:DataRecordPresenter}">

The style:

    <Style x:Key="MyDataRecordCellAreaStyle" TargetType="{x:Type igDP:DataRecordCellArea}">
        <!--Disable highlighting active record-->
        <Setter Property="BackgroundActive" Value="{x:Null}" />
        <Setter Property="BorderActiveBrush" Value="{x:Null}"/>
       
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type igDP:DataRecordCellArea}">
