Preview Section

Preview sections are non-editable regions in data rows that allow large memo fields to be displayed across all View columns, thus the preview section’s width is equal to the total column width. A preview is not displayed for the new item row and auto filter row.

 

VisualElems_GridView_PreviewSection

Note

If the Row Auto-Height or Preview Sections feature is enabled, pixel-based vertical row scrolling is not in effect. See GridOptionsBehavior.AllowPixelScrolling to learn more.

 

The table below lists the main properties affecting element appearance.

Appearance

The GridViewAppearances.Preview property.

Custom Draw Event

The GridView.CustomDrawRowPreview event.

Visibility

The GridOptionsView.ShowPreview option.

Height

The GridOptionsView.AutoCalcPreviewLineCount and GridView.PreviewLineCount properties.

The GridView.MeasurePreviewHeight event.

Contents

The GridView.PreviewFieldName property and the GridView.CalcPreviewText event.

The GridView.GetRowPreviewDisplayText method allows preview text to be returned.
