add all children in treeview

im using the same function as the LLTreeView example (InitWorkspace, addLLNodes) to populate my listTreeView with LLTreeNodes.

What's the easiest way to make it populate the entire livelink database below a given node, into the listTreeView? I'm asking because when i attempt to use a recursive function to iterate through the nodes in the treeview (I'm really interested in applying new permissions to the LLTreeNodes that the Nodes in the treeview represent) I can only apply the changes to the first layer of children below the visible folders in the treeview. Would calling the addLLNodes recursively be the easiest way? If i could get a little help on that it'd be greatly appreciated. I'm jsut not sure what to do once the first AddLLNodes completes. Should i be using something like this pseudo code once addLLNodes returns:

foreach(TreeNode n in (the newly generated Nodes from addLLNodes))
{
            cast LLNode to TreeNode
            check that the TreeNode has Children
            foreach(TreeNode tn in n.Node.Nodes)
                         addLLNodes(tn)
}

or is there a better way?
Thanks in advance

Hi, Jonathon.

I'm not sure populating the tree view with the all of the nodes from the enterprise workspace is a good idea since there could be a very large number.

Are you getting an error when trying to apply new permissions?

I was going about it wrong, sorry about that. But I have a new problem if you can help that'd be great.

Basically, I have a reference folder who has a set of permission. I want to apply the permissipons of that reference folder to a folder and all it's subfiles/folders (i call the folder to apply permissions to top folder)

private void SetPermissions_Click(object sender, EventArgs e)
        {
            Node node = fDocManService.GetNode(fDocsAuthentication, TopFolder_ID);
            LLTreeNode treeNode = new LLTreeNode();
            treeNode.Data = node;
            Set_Node_Permissions(node);
        }

private void Set_Node_Permissions(LLTreeNode LLtreeNode)
        {
            foreach (LLTreeNode node in LLtreeNode.Nodes)
            {
                // If the current node has child nodes, call the CheckAllChildsNodes method recursively.
                NodeRights noderights = fDocManService.GetNodeRights(fDocsAuthentication, node.ID);
                //noderights.OwnerGroupRight.RightID = Convert.ToInt32(rGroupID);
                //noderights.OwnerRight.RightID = Convert.ToInt32(rOwnerID);
                //MessageBox.Show(node.Text);
                if (node.ChildCount > 0)
                {

                    this.Set_Node_Permissions(node);
                }
            }
}

The program compiles and runs but the problem is that I need an LLTreeNode to determine the ChildCount, but the LLtreeNode.Nodes field is always 0 so the foreach loop never runs. The ChildCount is correct though. I'm not really sure what to do here, so any help would be greatly appreciated. Thanks

sorry that should be

Set_Node_Permissions(treeNode);
not
Set_Node_Permissions(node);

The LLTreeNode.Nodes property has to be assigned values. You've only assigned a value to the Data property.

At any rate, the DocumentManagement service has a method that might be of interest to you: updateNodeRightsContext().

After you call this, method, call updateNodeRights() with the returned context object to determine the status of the operation (it could take a long time).

Hey Scott, I'm a alittle confused at how you'd use that to replace the Group Owner ID, Owner ID and ACL list.

When i bring up UpdateNodeRightsContext, i only get the option for passing it a NodeRights[], but doesn't seem to indicate how you set those particular values. I assume using noderights is read only right? Since i tried assigning the new value using noderights, but that didn't work.

Hi, Jonathon.

To replace the Owner, OwnerGroup, and Public rights you can simply call UpdateNodeRightsContext with an array of NodeRight objects (note that it is not the NodeRights object) that have the Type property set properly ("Owner", "OwnerGroup", and "Public", respectively). For the ACL rights it's a little trickier since both the Type and the RightID are used to identify the entry in the list.

If you wanted to replace all of the ACL rights entries with the ones from your source node, you would first have to remove all existing entries from each node and then add the new ones. The addition could be done using a single call to UpdateNodeRightsContext since the set of NodeRight objects would be consistent, but the deletion would have to be done on a node-by-node basis because the NodeRight objects that need to be removed could be different for each one.

Thanks,

Scott

thanks Scott that did the trick.

I just have on emore question if you can help me with it.

I'd like to be able to search through the available LiveLink groups given keywords and names. I'm trying to use the MemberService.GetSearchResults, but I'm not sure what to do about the pagehandle object that you need. I don't see it used anywhere else in the example. If that the right method to be using how do I set up the PageHandle object?

Thanks

sgrasley

Hi, Jonathon.

First instantiate a MemberSearchOptions object and set its properties for the search you want to do. Then you can pass it to SearchForMembers(), which returns an instance of PageHandle. Pass this object to GetSearchResults() and you'll get an instance of MemberSearchResults, which has the list of members in its Members property.

thanks,

Scott
