TdxCustomNavBar.OnGetGroupHint Event

Enables you to override or hide hints displayed for NavBar groups.

Declaration

property OnGetGroupHint: TdxNavBarGetGroupHintEvent read; write;

Remarks

This event occurs every time a NavBar group is about to display its hint, even if the group’s Hint property value is an empty string.

The Sender parameter provides access to the NavBar control that raised the OnGetGroupHint event. Cast the parameter value to the TdxNavBar class to access the control’s API members.

Use the AGroup parameter to identify and access the group that is about to display a hint.

The AHint parameter specifies the group’s hint text within an OnGetGroupHint event handler. Assign a text string to the parameter to override an existing hint. To hide the hint, assign an empty string instead.

Note

The OnGetGroupHint event occurs only if the OptionsBehavior.Common.ShowGroupHint property is set to True.
