Hello Tammy,

It has been a while since you have made this post, in case you still need any support about it please feel free to contact us. Regarding this issue, I reviewed your requirements and I can suggest you try catching the event SelectedItemChanged of the XamDataGrid and in the handler to set:

       private void xdg_SelectedItemsChanged(object sender, Infragistics.Windows.DataPresenter.Events.SelectedItemsChangedEventArgs e)

        {

            xdg.SelectedItems.Records.Clear();

            xdg.SelectedItems.Cells.Clear();

            xdg.ActiveRecord = null;       

        }

And also to change the color of the DataRecordCellArea brushes that is displayed when the selection is made. To do this you can try:

        <Style TargetType="{x:Type igDP:DataRecordCellArea}">

            <Setter Property="BackgroundHover" Value="Transparent"/>

            <Setter Property="BackgroundActive" Value="Transparent"/>

            <Setter Property="BackgroundSelected" Value="Transparent"/>

            <Setter Property="BorderActiveBrush" Value="Transparent"/>

            <Setter Property="BorderHoverBrush" Value="Transparent"/>

            <Setter Property="BorderSelectedBrush" Value="Transparent"/>

        </Style>

If you still need any assistance on the matter, please do not hesitate to ask.
