Normally, the list of "closed" groups is visible to all users. (registered or not)
Then only members can access. Right?
But there is a way to hide the list of groups closed to users who are not members of those groups?
(e.Item.ItemType == ListViewItemType.DataItem)
SnGroupDTO group = ((ListViewDataItem)e.Item).DataItem
e.Item.Visible = group.IsPublic;
I fill out a new web application in which is contained my webpart?
