TcxCustomGridRecord.Expandable Property

Gets whether the record can be expanded and/or collapsed.

Declaration

property Expandable: Boolean read;

Property Value

Type
Boolean

Remarks

If this property returns True, then the record can be successfully expanded and collapsed using the record’s Expand, Collapse methods and the Expanded property. The Expandable property also determines whether the View’s ViewData.Expand and ViewData.Collapse methods will affect the record.

If the Expandable property returns False, the View will not paint visual elements that allow end-users to expand and collapse records.

As implemented in the TcxCustomGridRecord class, the Expandable property simply returns False. This property’s actual value depends on the record type (TcxCustomGridRecord descendant). The table below lists record classes that support expanding and collapsing and provides information on the Expandable property return value.

Record class	The Expandable property’s return value
TcxGridGroupRow	Returns True except for the case when the data controller’s dcoGroupsAlwaysExpanded option is enabled.
TcxGridMasterDataRow	Returns True if at least one of the following conditions is met: The master row has detail rows; The View’s OptionsView.ExpandButtonsForEmptyDetails option is enabled; The master row is already expanded.
TcxGridCard	Returns True if the View’s OptionsCustomize.CardExpanding property value is True.
