Preview Section

Preview sections are non-editable regions in nodes that allow large memo fields to be displayed across all the Tree List's columns, thus the preview section's width is equal to the total column width.

 

The table below lists the main properties affecting the element's appearance:

Appearance The TreeListAppearanceCollection.Preview property.
Custom Draw Event The TreeList.CustomDrawNodePreview event.
Visibility The TreeListOptionsView.ShowPreview option. This option can be accessed using the Tree List's TreeList.OptionsView property.
Height The TreeListOptionsView.AutoCalcPreviewLineCount option and the TreeList.PreviewLineCount property.

The TreeList.MeasurePreviewHeight event.

Contents The TreeList.PreviewFieldName property and the TreeList.GetPreviewText event.
