This is not a problem, but a solution to a problem that I had that I thought others might want for reference.

Issue: I have a treeview populated via an xml file that shows the entire menuing. I have parent-node 'groups' like reports, but under it, I might have several sub-group childnodes that I want to display or not depending on the users login role(s).

Say a person has two roles: ahsaa, officials. Both have reporting needs, but they may not be inclusive. ahsaa role might be the parent-parent role that has everything displayed, but it makes/made no sense to duplicate menu options multiple times siply due to that issue.

So, xmlfile section:

<folder name="Reports" id="Reports">
<folder name="AHSAA" id="AHSAA">
<demo name="Sports Clinic"></demo>
</folder>
<folder name="Officials" id="Officials">
<demo name="Sports Clinic"></demo>
</folder>
<folder name="Coaches" id="Coaches">
<demo name="Sports Clinic"></demo>
</folder>
</folder>

Has parent of 'Reports' and several childnodes (ahsaa, officials, coaches)

In my situation, if I do nothing all three childnodes are displayed. However, the reports avaialble to the official might not be valid for the coaches, whom are sub-set of officials in certain functions. So, in order to display officials reporting needs, but not display coaches, the code I found that worked is:

If Roles.IsUserInRole(memUser.UserName.ToString, "REPORTS_OFFICIALS") Then
For Each node2 As EO.Web.TreeNode In tvOption.Nodes
If node2.Text = "Reports" Then
tvOption.Nodes(node2.Index).Visible = True

'get childnodes and filter based on roles type
For Each cnode As EO.Web.TreeNode In node2.ChildNodes

' we need to check to see if user also has report roles for other sections, like Officials, Coaches, etc.

'Role - AHSAA
If Not Roles.IsUserInRole(memUser.UserName.ToString, "REPORTS_AHSAA") Then
'user not in AHSAA role, so remove
If node2.ChildNodes.Item(cnode.Index).Text = "AHSAA" Then
node2.ChildNodes.Item(cnode.Index).Visible = False
End If
End If

'Role - Coaches
If Not Roles.IsUserInRole(memUser.UserName.ToString, "REPORTS_COACHES") Then
' user not in Coaches role, so remove
If node2.ChildNodes.Item(cnode.Index).Text = "Coaches" Then
node2.ChildNodes.Item(cnode.Index).Visible = False
End If
End If
Next
Exit For
End If
Next
End If
End If

so, based on this, I can have a user in multiple 'report' roles, and then check on design time what if anything I need to display/not. Yes, I know there is somewhat duplication on checking if user is in other roles for the 'parent role', but unless I limit them to a single report-role, the sysadmin type could check multiple checkboxes that represent roles.

Anyway, thought I throw this out in case anyone was having similar 'concept' issues like I did/had until Jack put me on the right path (e.g., figure it out yourself!!! and look at examples in code/forum). Really Jack, thanks. your comments helped me think clearer on functionality vs.coding.
