How to show only Structure Groups in Item selector

Question

We are using the item selector tool in Tridion 2011 SP1 HR1.

We are upgrading to Tridion 2013 SP1, during upgrade we build the tool with latest CoreService DLL. Web.Config is also updated with correct CoreService end points.

After deployment in DEV box everything is working fine, but we are facing an issue, On click of Custom URL link in component Item selector is getting opened, but it is showing all the organizational items, whereas we need only Structure Group to be shown as we need only Page TCMID.

We don't want to pass ItemTypes in the CustomUrl as a query parameter.

Is there any other way to pass ItemTypes so that only the structure Group will be visible in ItemSelector.

Answer 1

We don't want to pass ItemTypes in the CustomUrl as a query parameter.

Any particulair reason why not? The Item Selector was designed to show you a specific set of item types only when you supply the ItemTypes in the CustomUrl as a query parameter. You can simply set this on a per field bases in the Custom URL in your Schema.

If for any reason you don't want to do this (I would be interested to hear why, and see if that is a use case for which a feature might need to be added), you have all the source code available, and can update this yourself to make it suit your requirements.

See Pankaj's answer for a possible solution, but that change will make it a Structure Group Selector, rather than an Item Selector. Even simpler would be to change ItemSelector.aspx and hardcode the allowed types:

<form id="tree" runat="server">
    <sdl:TridionTreeView ID="TridionTreeView" runat="server" StartFromUri="tcm:0-0-0" SelectTypes="4" />
</form>

(not tested but if I remember what I wrote, I think that will do the trick without you needing to recompile and change code. Plus this would still allow you to specify a different selection of item types on the querystring to override.)

I am not sure if it is useful, but I have modified the code in ItemSelector for TridionTreeView.ascx in PopulateNode method as below. This will give you all the Structure Groups only:

public void PopulateNode(Object sender, TreeNodeEventArgs e)
        {
            XmlDocument doc = new XmlDocument();
            TcmUri uri = new TcmUri(e.Node.Value);
            if (uri.IsUriNull) // the root node
            {
                PublicationsFilterData filter = new PublicationsFilterData();
                XElement publications = _client.GetSystemWideListXml(filter);
                doc.Load(publications.CreateReader());
            }
            else
            {
                switch (uri.ItemType)
                {
                    case ItemType.Publication:
                        PublicationData pub = (PublicationData)_client.Read(uri.ToString(), new ReadOptions());
                        TreeNode tnS = CreateTreeNode(pub.RootStructureGroup.Title, pub.RootStructureGroup.IdRef);
                        if (tnS != null)
                        {
                            e.Node.ChildNodes.Add(tnS);
                        }
                        break;
                    case ItemType.StructureGroup:
                        OrganizationalItemItemsFilterData filter = new OrganizationalItemItemsFilterData();
                        filter.ItemTypes = new Tridion.ContentManager.CoreService.Client.ItemType[] 
                                                    { Tridion.ContentManager.CoreService.Client.ItemType.StructureGroup };
                        filter.Recursive = false;
                        XElement items = _client.GetListXml(uri.ToString(), filter);
                        doc.Load(items.CreateReader());
                        break;
                }
            }

            foreach (XmlElement item in doc.SelectNodes("//tcm:Item", _nsMgr))
            {
                TreeNode tNode = CreateTreeNode(item.GetAttribute("Title"), item.GetAttribute("ID"));
                if (tNode != null)
                {
                    e.Node.ChildNodes.Add(tNode);
                }
            }
        }
