Use the Bold, Italic, Underline and StrikeOut properties to apply different font attributes to the group. Use the Caption property to display different parts of the caption using HTML format. Use the Font property to specify the control's font. Use the StrikeOut property to specify whether the item's font is displayed with a horizontal line through it.

The following VB sample specify that all groups should appear in strikeout:

Private Sub ExplorerBar1_AddGroup(ByVal Group As EXPLORERBARLibCtl.IGroup)
    With Group
        .StrikeOut = True
    End With
End Sub

The following C++ sample specify that all groups should appear in strikeout:

void OnAddGroupExplorerbar1(LPDISPATCH Group) 
{
	CGroup group( Group ); group.m_bAutoRelease = FALSE;
	group.SetStrikeOut( TRUE );
}

    With e.group
        .StrikeOut = True
    End With
End Sub

The following C# sample specify that all groups should appear in strikeout:

private void axExplorerBar1_AddGroup(object sender, AxEXPLORERBARLib._IExplorerBarEvents_AddGroupEvent e)
{
	e.group.StrikeOut = true;
