Re: Listbox Treeview doesnot filter data based on selection.
The ListBox option for TreeView is what it is. It is either on or off and there are no additional options (such as "Expand all nodes").
I would suggest that it is filtering based on selections, but you might not be seeing it - you should see the "beacons" to indicate selection but, unless the nodes are expanded, you may not see the actual selected values.
You might want to turn off the "Size to Data" option on the Layout tab of the properties so that you can fix the size of the list box.
You could consider going with an advanced Extension Object to do what you want, but would it be as simple perhaps to just go with a List Box and a drill-down group?
