                               A reference to a TreeView-style DataWindow control  |

                               row  |

                               The TreeView level of the group  | 
                        
Return value
Returns true if the group is expanded and false if the group is not expanded. IsExpanded also returns false if the DataWindow is not a TreeView DataWindow or the row or groupLevel is invalid.
Usage
A TreeView DataWindow has several TreeView level bands (groups) that can be expanded and collapsed. You can use the IsExpanded method to test whether or not a group in a TreeView DataWindow is expanded.
Examples
The following example performs a test to determine whether the group that contains row 3 at TreeView level 2 is expanded:
boolean lb_expanded lb_expanded = dw_treeview.IsExpanded(3,2)
