Yeah, PDFs have pretty much rendered the PSRs obsolete. However....

Another option is to keep track of each NODE of the tree and it's state (expanded or collapsed) in an array, then when you open the second DW"


dw_2.SetRedraw (FALSE)

// bulk copy the data  from dw_1 into dw_2
// - the easiest case is when the contents are identical, then you can ShareData between the DWs.

FOR (ll_node = 1 TO ll_num_of_nodes)

   lb_expanded = lb_node_state_array [ll_node]

   IF (lb_expanded) THEN
      // Expand the node
   ELSE
      // collapse the node
   END IF

NEXT

Hi Mahound;

   The PSR is the "original" DWO source plus the DWO's primary data buffer. It does not track the state of the Tree itself. Thus, when your PSR is imported into another DW Control, the tree will open collapsed.

    Saving the Treeview DWO though to a PDF will preserve the current "state" of the tree.

Regards ... Chris
