Contour, adding custom validation without using code first 4

Just a quick post to share the answer to a question I got on the forum.

So as you can see in the code first examples, creating Contour forms code first also allows for an easy way to add extra (custom validation)

But there is also a way to add custom rules when you are designing the form in the UI.

There is an event you can hook into to add validation errors, a typical case for this would be a password and repeast password field where you need to make sure the input is the same.


So in the form designer these are just 2 password fields with no link


And to add the extra validation rules

    public class ContourValidation : ApplicationEventHandler
        protected override void ApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
            FormRenderController.FormValidate += FormRenderController_FormValidate;
        void FormRenderController_FormValidate(object sender, Umbraco.Forms.Mvc.FormViewEventArgs e)
            if (e.Form.Name == "FormWithExtraValidation")
                var s = sender as Controller;
                if (s != null)
                    var pwf = e.Form.AllFields.SingleOrDefault(f => f.Caption == "Password").Id.ToString();
                    var rpwf = e.Form.AllFields.SingleOrDefault(f => f.Caption == "Repeat password").Id.ToString();
                    var password = e.Context.Request[pwf];
                    var repeatpassword = e.Context.Request[rpwf];
                    if(password != repeatpassword)
                        s.ModelState.AddModelError(rpwf, "passwords don’t match");

So hook into the FormValidate event of the FormRenderController that will fire when a form validates

You can then add extra model errors to the modelstate

Integrate Umbraco Contour with third party service, post to Podio App 1

Just a quick blog post with an example on how to attach a third party service to Contour (the Umbraco form builder).

You can attach extra functionality to a Contour form by setting up workflows,

So by default a Contour form will store it’s data but if you want extra stuff (like sending an email) you can do that by adding a workflow..

There are several out of the box workflows you can use…now in my case I wanted to extend Contour to post it’s record date to a podio app

So first of all I need a podio API key, you can get that here

Once that is settled we can use the API, there is even a .net library available

Next of course is to setup an app in podio, that’s pretty easy with the app builder,

So I just created a new app that has a single item and that item has a single text block (that’s the text block we’ll populate with contour record data)


Now I’m all set the create the workflow, here is the code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Xml;
using System.Xml.XPath;
using Podio.API;
using Podio.API.Model;
using Podio.API.Utils.ItemFields;
using Umbraco.Forms.Core;
using Umbraco.Forms.Core.Enums;
using Umbraco.Forms.Data;
using Umbraco.Forms.Data.Storage;
namespace Contour.Addons.Podio
    public class AddRecordToPodioSpace : WorkflowType
        [Umbraco.Forms.Core.Attributes.Setting("Client id")]
        public string ClientId { get; set; }
        [Umbraco.Forms.Core.Attributes.Setting("Client secret ")]
        public string ClientSecret { get; set; }
        public string UserName { get; set; }
        public string Password { get; set; }
        public string AppId  { get; set; }
        public string PodioTextFieldId { get; set; }
        public AddRecordToPodioSpace()
            this.Id = new Guid("55517EB2-8D61-483C-A3DA-7850FCE05996");
            this.Name = "Send record to podio space";
            this.Description = "Send record to podio space";
        public override List<Exception> ValidateSettings()
            List<Exception> l = new List<Exception>();
            if (string.IsNullOrEmpty(ClientId))
                l.Add(new Exception("’ClientId’ setting has not been set"));
            if (string.IsNullOrEmpty(ClientSecret))
                l.Add(new Exception("’ClientSecret’ setting has not been set’"));
            if (string.IsNullOrEmpty(UserName))
                l.Add(new Exception("’UserName’ setting has not been set’"));
            if (string.IsNullOrEmpty(Password))
                l.Add(new Exception("’Password’ setting has not been set’"));
            return l;
        public override WorkflowExecutionStatus Execute(Record record, RecordEventArgs e)
                RecordsViewer viewer = new RecordsViewer();
                XmlNode xml = viewer.GetSingleXmlRecord(record, new System.Xml.XmlDocument());
                XPathNavigator navigator = xml.CreateNavigator();
                XPathExpression selectExpression = navigator.Compile("//fields/child::*");
                selectExpression.AddSort("@pageindex", XmlSortOrder.Ascending, XmlCaseOrder.None, "", XmlDataType.Number);
                selectExpression.AddSort("@fieldsetindex", XmlSortOrder.Ascending, XmlCaseOrder.None, "",
                selectExpression.AddSort("@sortorder", XmlSortOrder.Ascending, XmlCaseOrder.None, "", XmlDataType.Number);
                XPathNodeIterator nodeIterator = navigator.Select(selectExpression);
                string list = "<dl>";
                while (nodeIterator.MoveNext())
                    list += "<dt><strong>" +
                                nodeIterator.Current.SelectSingleNode("caption").Value) + ": </strong><dt><dd>";
                    XPathNodeIterator values = nodeIterator.Current.Select(".//value");
                    while (values.MoveNext())
                        list +=
                                .Replace("\n", "<br/>") + "<br/>";
                    list += "</dd>";
                list += "</dl>";
                Client client = Client.ConnectAsUser(ClientId,
                Item i = new Item();
                var textField = i.Field<TextItemField>(PodioTextFieldId);
                textField.ExternalId = PodioTextFieldId; 
                textField.Value = list;
                client.ItemService.AddNewItem(Convert.ToInt32(AppId), i);
            catch (Exception ex)
                return WorkflowExecutionStatus.Failed;
            return WorkflowExecutionStatus.Completed;

So all the settings I need for podio are public properties marked with the settings attribute (so I can set those up when inserting the workflow)

THen the actuall workflow code will loop through all the record data and create html list. So you see it doesn’t matter how many fields you have it will pass all of them, this code is actually borrowed from the default send email workflow code, you can get all default providers code here (sourcecode tab at the bottom)

THen it wil make use of the podio api to create a new item and add it …

When I know deploy this to the site, I see a new workflow type


When choosing that type I can setup the settings


So when the settings are valid and the workflow is attached the form will now post to podio when it’s submitted (if workflow is attached to submitted stage)


So now I have a reusable component that I can deploy whenever I need a form that needs to integrate with podio!

Advanced property editor for Umbraco v7, single file deployment 3

One of the community packages that is in progress of being migrated to v7 is uComponents, as you may know the current v4/v6 version is compiled into a single assembly so it’s easy to deploy and to update (since it’s just a single file).

As a test I wanted to see if that’s also possible with v7 prop editors (so embed the views and controllers in the assembly).

If you have seen some of the v7 prop editor examples out there you know that to define your extra components you’ll need to create a manifest file (no more need for vs)

You can also define your prop editors in code (all the core ones are defined like that) just take a look at 

So if I take the char limit example the manifest file becomes

 [PropertyEditor("Example", "Example Editor", "/App_Plugins/Example/Resource/editor.html", ValueType = "TEXT")]
    [PropertyEditorAsset(ClientDependencyType.Javascript, "/App_Plugins/Example/Resource/controller.js")]
    public class ExamplePropEditor : PropertyEditor
        protected override PreValueEditor CreatePreValueEditor()
            return new ExamplePreValueEditor();
        internal class ExamplePreValueEditor : PreValueEditor
            public ExamplePreValueEditor()
                //create the fields
                Fields.Add(new PreValueField()
                    Description = "Enter the number of chars to limit on",
                    Key = "limit",
                    View = "requiredfield",
                    Name = "Number of chars"


THe editor and controller is still the same but in vs make sure to set the build action of the js and html file to embedded resource


Final bit is getting the controller and view out of the assembly and this is done with a simple controller

   public class EmbeddedController : Controller
        public FileStreamResult Resource(string id)
            var resourceName = Assembly.GetExecutingAssembly().GetManifestResourceNames().ToList().FirstOrDefault(f => f.EndsWith(id));
            var a = typeof(EmbeddedController).Assembly;
            return new FileStreamResult(a.GetManifestResourceStream(resourceName), GetMIMEType(id));
        private string GetMIMEType(string fileId)
            if (fileId.EndsWith(".js"))
                return "text/javascript";
            if (fileId.EndsWith(".html"))
                return "text/html";
            if (fileId.EndsWith(".css"))
                return "text/stylesheet";
            return "text";

Of course since it’s a normal mvc controller it isn’t auto routed and I need to setup the routing

    public class RouteConfig
        public static void RegisterRoutes(RouteCollection routes)
                name: "Example",
                url: "App_Plugins/Example/{action}/{id}",
                defaults: new { controller = "Embedded", action = "Resource", id = UrlParameter.Optional }


And make sure that the route get’s registered when the application starts

 public class StartUpHandlers : ApplicationEventHandler
        protected override void ApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)

So now we can fetch the embedded resource by requesting




And that’s it, build and just deploy the assemby to the umbraco v7 instance

Analytics for Umbraco 7 1

Led by Warren Buckley and in collab with Anders Bjerner we released a new package for Umbraco v7 today!


The package adds a new section to your Umbraco v7 installation which allows you to view your Google Analytics statistical information directly inside Umbraco. So it’s easy for content editors, site owners to view stats without having to move to a google account and the google analytics site.

Of course your site needs to have a google analytics profile and it needs to have the necessary script includes to gather stats. The package will simply interact with the google analytics API to fetch data and display those in the Umbraco backoffice.


Just get it from and go to developer/packages/install local package in your Umbraco backoffice


Then follow the installation wizard and as a final step you should see this screen


Then use the button to move to the new section.


Make sure to clear your cache if you are getting 404 error messages and then hit f5 (v7 needs some good cache busting)

Next you’ll see the settings screen where you need to authorize against google analytics and select the correct profile( again the package won’t gather stats that is done by google analytics so make sure that is setup for the site first).


So hit the Authorise button and you should see a new window popup


Login with google and then authorize the application (this will give it access to the stats)

Once that is done you should get a confirm message


Closing that will reload the settings screen and allow you to choose an account and profile

So select and then save the settings



Once the profile is selected you can view stats Smile

Dashboard will show some stats sfrom latest 7 days


Fur further stats, just select something from the tree, on those detailed stats you can also specify a date range (that will be remembered when moving between stats)


So that’s a quick intro, make sure to give it a try

Config tree On Umbraco v7 0

Another package ready for umbraco v7 (well actually thanks to the awesome work by Per and Shannon it already worked on v7 it just needed some super small UI updates, updating tree icon and updating save button)


Also added ctrl-s support for saving the file

There is no spoon 1.0 Release (matrix prop editor for Umbraco v7) 0

I’ve just released a packaged version of the matrix prop editor I created as an example prop editor for Umbraco v7.

The package is available for download on (this if for Umbraco v7 only)

The settings looks like


So you can set

  • initial number of cols and rows
  • let the content editor add/remove rows
  • Show row labels
  • define labels for rows and cols

An example of the editor (with manage rows enabled)


Advanced property editors for Umbraco v7, dynamic prevalue editors 0

Working with the value from 1 prevalue editor on the other, that’s easily possible with Umbraco v7 Smile

Since you can access the editorState

As an example I’ve updated the matrix prop editor

What I wanted to do is to make it possible to setup headers for the rows and columns but since the amount of rows and columns isn’t fixed…

So first step is to create a new view and controller for the custom prevalue editor (just use what you know from creating prop editors)

And then use that as a prevalue editor

                    label: "Labels",
                    description: "Enter the labels for the cols/rows",
                    key: "rowheaders",
                    view: "~/App_Plugins/MatrixEditor/matrixlabeleditor.html",

Then in the controller it’s possible to inject the editorState and access the other prevalues

    function ($scope,editorState) {
    $scope.current = editorState.current;
    $scope.rows = _.where($scope.current.preValues, {key: "rows"})[0];
    $scope.cols = _.where($scope.current.preValues, {key: "cols"})[0];

(using some underscore the easily fetch the correct prevalue)

So once I have the amount of rows and cols I can dynamic build up my editor

<div ng-controller="Nibble.MatrixLabelEditor" class="matrix-label-editor">
            <h6>Column labels</h6>
            <div  ng-repeat="label in model.value.collabels track by $id($index)" class="lbl-cont">
                <input type="text" ng-model="model.value.collabels[$index]"/>
            </div >
         <h6>Row labels</h6>
         <div ng-repeat="label in model.value.rowlabels track by $id($index)" class="lbl-cont">
            <input type="text" ng-model="model.value.rowlabels[$index]"/>

collabels and rowlabels are both arrays

The end result looks like


And then of course the prop editor view needs to be updated to include the headers (only for cols atm)

<div ng-controller="Nibble.MatrixEditor">
              <th ng-repeat="head in model.config.rowheaders.collabels">{{head}}</th>
            <tr ng-repeat="row in model.value">
                <td ng-repeat="col in row  track by $id($index)">
                     <input type="text" ng-model="row[$index]"></td>


For a quick demo check out

As a final touch I’ll need to get rid of refreshing the page but haven’t figured that one out yet

Sourcecode is available on github

Advanced property editors for Umbraco v7, prevalue editors 1

As you could see in the 2 prop editors for Umbraco examples it’s super easy to add config options to your v7 prop editors (,

As it mentions in the manifest docs there is a prevalues part where you can setup your config options…


prevalues: {
            fields: [
                    label: "Number of chars",
                    description: "Enter the number of chars to limit on",
                    key: "limit",
                    view: "requiredfield",
                    validation: [
                            type: "Required" 

Results in

Changing the type of prevalue editor

Of course you aren’t limited to a simple text input if you take a look at the available out of the box types (found in \Umbraco\Views\prevalueeditors )

You’ll find


So if I want to update my matrix prop editor to have numeric prevalues (since I need to define number or rows and columns)

I just need the name of the view (and don’t need the .html)

That then becomes

            fields: [
                    label: "Number of columns",
                    description: "Enter the number of columns",
                    key: "cols",
                    view: "number",
                    validation: [
                            type: "Required" 
                    label: "Number of rows",
                    description: "Enter the number of rows",
                    key: "rows",
                    view: "number",
                    validation: [
                            type: "Required" 

And results in


Using prop editors as prevalue editors

It’s also possible to plug in custom prevalue editors, all  you need to do is point it to a view and you can use a prop editor as a prevalue editor!

So adding this

                    label: "Testing",
                    description: "Test",
                    key: "test",
                    view: "~/App_Plugins/MatrixEditor/matrixeditor.html",
                    validation: [
                            type: "Required" 

Will make it possible to use the matrix prop editor as a prevalue editor on it’s own settings


Currently you’ll have to manually check in your controller if the config has values or not since it’s not possible to set default values that get passed to the prevalue editor (but should be possible soon)
