Property Value

Type	Default	Description
DefaultBoolean	Default	A DefaultBoolean value that specifies if the top visible group row is always displayed when scrolling through grouped data.

Available values:

Name	Description
True	true. DefaultBoolean.True has a constant value of 0, while the standard true value corresponds to a value of 1. In Visual Basic, do not use implicit conversion of Boolean values to DefaultBoolean, and vice versa, as the conversion may produce incorrect results.
False	false. DefaultBoolean.False has a constant value of 1, while the standard false value corresponds to a value of 0. In Visual Basic, do not use implicit conversion of Boolean values to DefaultBoolean, and vice versa, as the conversion may produce incorrect results.
Default	The default behavior determined by the control’s logic.

Remarks

If the AllowFixedGroups property is set to True, the top visible group row is anchored to the top of the grid while scrolling through grouped data. In addition, a special icon is displayed to indicate that grouped data is partially visible:

The AllowFixedGroups property’s Default value is equivalent to True in server mode, and to False in regular binding mode.

The AllowFixedGroupsproperty is only in effect when the GridView.ScrollStyle property is set to its default value (a combination of the LiveVertScroll and LiveHorzScroll flags).
