Difference in in EnableGroupTree and DisplayGroupTree

[redmondson92]

I am integrating crviewer.dll and craxdrt.dll (V8.5) into an ActiveX control using VB. I am trying to control the display of the group tree based on report content (ie if it contains groups) when I drill down on a subreport or group.

Generally, i have found the following:

enablegrouptree -- toggles appearance of the group tree button in the toolbar

displaygrouptree -- toggles the appearance of the group window on the left of the window

Does anyone have insight on how these 2 relate to each other??

The problem I am having is that when I close a tab, my group tree stays on even though I am turning it off? Heres my code:

Private Sub CRViewer1_CloseButtonClicked(UseDefault As Boolean)

Dim strCurRpt As String
Dim strCurTabName As String

strCurRpt = CRViewer1.GetViewName(strCurTabName)

'log message
If (mbolLogReport) Then objMessageLog.LogMessage ("Closed tab: " & strCurTabName & " which contains report: " & strCurRpt)

'check tab count and turn it off if only one tab is shown
If CRViewer1.ViewCount <= 2 Then
mbolTabViewable = False
CRViewer1.DisplayTabs = False
End If

'turn off group tree -- need to add check if there is a group or not
CRViewer1.EnableGroupTree = False
CRViewer1.DisplayGroupTree = False
mbolTreeControl = False

'enable default behavior
UseDefault = True
End Sub

Notice that I turn off the enable and display, but when I run this, the group tree stays on? Could the UseDefault be doing it? Or are there report properties that affect it too? (I have turned off the &quot;create group tree&quot; option in the Report Options). Thanks for any input.
