Remarks

The DetailHeight property of pattern Views specifies the maximum height its clones have when an end-user expands master rows. When you change the DetailHeight property of an expanded clone view, this clone’s height is changed. A detail does not display empty space below its rows. So, the detail height cannot be greater than the height required to display all detail rows.

The following applies to Layout Views (LayoutView objects), when they are displayed as details.

Auto-height mode is enabled for detail Layout Views by default. The DetailHeight property specifies the detail’s maximum height. The detail shrinks its height to vertically fit displayed cards (see LayoutViewOptionsView.ViewMode and LayoutViewOptionsMultiRecordMode.MaxCardRows).

If you need a detail height to be fixed and equal to a specific value, disable the auto-height feature with the LayoutView.DetailAutoHeight property and specify the required height via the DetailHeight setting.

The detail auto-height feature is not in effect if card stretching is enabled via the StretchCardToViewHeight property (see LayoutViewOptionsSingleRecordMode.StretchCardToViewHeight and LayoutViewOptionsMultiRecordMode.StretchCardToViewHeight).
