Custom Section with multiple trees and actions

I created a custom section which loads a tree. The root tree has two nodes.

The create action on the two main nodes should preform a seperate action. So far I have this:

        public override void Render(ref XmlTree tree) {
           if (string.IsNullOrEmpty(this.NodeKey)) {
               //Add the first level
               XmlTreeNode xNodeProfileKeywords = XmlTreeNode.Create(this);
               xNodeProfileKeywords.NodeID = "manageProfileKeywords";
               xNodeProfileKeywords.NodeType = "manageProfileKeywords";
               xNodeProfileKeywords.Text = "Profiel sleutelwoorden";
               xNodeProfileKeywords.Icon = "folder.gif";
               xNodeProfileKeywords.HasChildren = true;
               xNodeProfileKeywords.Source = this.GetTreeServiceUrl(xNodeProfileKeywords.NodeID);
               xNodeProfileKeywords.Menu.Clear();
               xNodeProfileKeywords.Menu.AddRange(new List<IAction>() { ActionNew.Instance });
               tree.Add(xNodeProfileKeywords);

               XmlTreeNode xNodeCompanies = XmlTreeNode.Create(this);
               xNodeCompanies.NodeID = "manageStringTranslations";
               xNodeCompanies.NodeType = "manageStringTranslations";
               xNodeCompanies.Text = "Vertaalbare tekst";
               xNodeCompanies.Icon = "folder.gif";
               xNodeCompanies.HasChildren = true;
               xNodeCompanies.Source = this.GetTreeServiceUrl(xNodeCompanies.NodeID);
               xNodeCompanies.Menu.Clear();
               xNodeCompanies.Menu.AddRange(new List<IAction>() { ActionNew.Instance });
               tree.Add(xNodeCompanies);

           } else if (this.NodeKey == "manageProfileKeywords") {
               using (MyHypothekerUmbracoEntities rep = new MyHypothekerUmbracoEntities()) {
                   var allProfileKeywords = rep.ProfileKeywordSet.OrderBy(pk => pk.Keyword);
                   foreach (var profileKeyword in allProfileKeywords) {
                       XmlTreeNode xNode = XmlTreeNode.Create(this);
                       xNode.NodeID = profileKeyword.ProfileKeywordID.ToString();
                       xNode.Text = profileKeyword.Keyword;
                       xNode.Icon = "hyp_profiles_16.png";
                       xNode.Action = "javascript:openProfileKeyword('" + xNode.NodeID + "')";
                       tree.Add(xNode);
                   }
               }
           } else if (this.NodeKey == "manageStringTranslations") {
               using (MyHypothekerUmbracoEntities rep = new MyHypothekerUmbracoEntities()) {
                   var allReplacements = rep.StringReplacementItemSet.OrderBy(r => r.StringReplacementKey);
                   foreach (var replacement in allReplacements) {
                       XmlTreeNode xNode = XmlTreeNode.Create(this);
                       xNode.NodeID = replacement.StringReplacementId.ToString();
                       xNode.Text = replacement.StringReplacementKey;
                       xNode.Icon = "hyp_profiles_16.png";
                       xNode.Action = "javascript:openStringTranslation('" + xNode.NodeID + "')";
                       tree.Add(xNode);
                   }
               }
           }
       }

In the UI.XML I tried to add this code to make teh magic happen:

    <nodeType alias="manageProfileKeywords">
        <header>Profile keywords</header>
        <usercontrol>/create/simple.ascx</usercontrol>
        <tasks>
            <create assembly="TamTam.Umbraco.Exensions" type="Sections.Custom.Tasks.ProfileKeywordsTasks" />
            <delete assembly="TamTam.Umbraco.Exensions" type="Sections.Custom.Tasks.ProfileKeywordsTasks" />
        </tasks>
    </nodeType>
    <nodeType alias="manageStringTranslations">
       <header>String translations</header>
       <usercontrol>/create/simple.ascx</usercontrol>
       <tasks>
           <create assembly="TamTam.Umbraco.Exensions" type="Sections.Custom.Tasks.StringTranslationsTasks" />
           <delete assembly="TamTam.Umbraco.Exensions" type="Sections.Custom.Tasks.StringTranslationsTasks" />
       </tasks>
   </nodeType>

But when I call the create a new item from the subroot items I get the following message

Server Error in '/' Application.

Input string was not in a correct format.

Anyone has any idea if this is the right way to go, what I am doing wrong or have another idea.

Hi Frank,

First off, looks like you are trying to Parse a string to an integer but something goes wrong - maybe your string is not a number (maybe because you are not hitting your usercontrol)?

Have you tried debugging to see what goes on in your usercontrol? And whether your Create action hits the right usercontrol (this is the standard umbraco create control right: <usercontrol>/create/simple.ascx</usercontrol>)?

Does the create action actually work on the rootnode or is it both root and subnode thats not working?

Hi again,

Here is the code that is throwing the exception in the simple.ascx usercontrol:

int nodeId = -1;
if (umbraco.helper.Request("nodeId") != "init")
    nodeId = int.Parse(umbraco.helper.Request("nodeId"));

Thought it might help you in the right direction - as you can se the "nodeId" querystring is parsed to an integer, which seems to fail.

Could it be these two nodes that are causing you problems (?):

xNodeProfileKeywords.NodeID = "manageProfileKeywords";

xNodeCompanies.NodeID = "manageStringTranslations";

Hi Morten,

Thanks for your reply, it really helped to solve the problem. Underneath my solution.

I gave the NodeID's for my second level items a string value because the rootnode has the value "init'. So I didn't think it should cause an issue. But you were right that this caused the issue. To make a workaround I decided to create a new page, to handle the creation of an new item.

So my UI.xml will look something like this:

    <nodeType alias="manageProfileKeywords">
        <header>Profile keywords</header>
        <usercontrol>/create/dbitem.ascx</usercontrol>
        <tasks>
            <create assembly="TamTam.Umbraco.Exensions" type="Sections.Custom.Tasks.ProfileKeywordsTasks" />
            <delete assembly="TamTam.Umbraco.Exensions" type="Sections.Custom.Tasks.ProfileKeywordsTasks" />
        </tasks>
    </nodeType>
    <nodeType alias="manageStringTranslations">
        <header>String translations</header>
        <usercontrol>/create/dbitem.ascx</usercontrol>
        <tasks>
            <create assembly="TamTam.Umbraco.Exensions" type="Sections.Custom.Tasks.StringTranslationsTasks" />
            <delete assembly="TamTam.Umbraco.Exensions" type="Sections.Custom.Tasks.StringTranslationsTasks" />
        </tasks>
    </nodeType>

I copied the code from simple.ascx.cs to my dbitem.ascx.cs and changed the code to:

int nodeId = -1;
int.TryParse(U.helper.Request("nodeId"), out nodeId);

This will make everything work as it should.

Maybe this code could be placed in the next release, to fix these kind of problems.

Thanks agian.
