Have a look at this issue for some improvements: http://issues.umbraco.org/issue/U4-192. Don't think a start node can be used yet. For now I use MNTP for that: http://our.umbraco.org/forum/core/umbraco-5-general-discussion/28363-Umbraco-5-MNTP-features#comment107718

Forgot to add... to see how MNTP does this, check the source for the constructor in "umbraco.editorControls.MultiNodeTreePicker.MNTP_DataEditor".

Cheers guys! however I Cannot figure out how to set the StartNodeID

var contentTree = TreeDefinitionCollection.Instance.Single(x => x.Tree.Alias.ToUpper() == "CONTENT");

                var filteredContentTree = new TreeDefinition(typeof(FilteredContentTree),
                                                             new umbraco.BusinessLogic.ApplicationTree(true, false, 0,
                                                                       contentTree.Tree.ApplicationAlias,
                                                                       "FilteredContentTree",
                                                                       contentTree.Tree.Title,
                                                                       contentTree.Tree.IconClosed,
                                                                       contentTree.Tree.IconOpened,
                                                                       "umbraco.editorControls",
                                                                       "MultiNodeTreePicker.FilteredContentTree",
                                                                       contentTree.Tree.Action),
                                                             contentTree.App);

                TreeDefinitionCollection.Instance.Add(filteredContentTree);
                CustomTreeControl treeControl  = new CustomTreeControl
                {
                    ID = "TreePicker",
                    IsDialog = true,
                    ShowContextMenu = false,
                    DialogMode = TreeDialogModes.id,
                    Height = 300,
                    StartNodeID = 1220,
                    TreeType = "FilteredContentTree"

                };

                TreeContainer.Controls.Add(treeControl);

but it isnt obeying the startNodeId >.< it still renders from the Root node :(

Hopefully i'm missing something really stupid and its a simple fix :(

Any ideas?

Love you all..

For DAMP I also set the start node of the media tree and copied that from how it works in MNTP. I don't know exactly what I did, but I remember it did give me a little trouble. Think it's best to look for "StartNode" in the source of MNTP and see in what places it all is used. Also had some javascript involved.

Thanks guys, I got it working with an extension of FilteredContentTree

<3

Sounds like a good package ;-).

@Stephen

I'm currently to to accomplish the same thing and having some trouble. Would you mind sharing your source?

Thanks!

@Dan & everyone, I did write this into a blog post, albeit I forgot to publish the thing.
