The TreeList extension provides a preview feature that allows each node to display a preview.
Preview areas allow large memo fields or custom data to be displayed across all the columns within the TreeList.
To enable the Preview feature, set the Settings.ShowPreview property to true.
You can specify the required data source field via the PreviewFieldName property to bind node previews to data.
Use the Styles.Preview property to access the style settings used to paint previews.
