Adding a new/custom section to umbraco, sample project

Simon Justesen, has a great post describing how to add new sections and trees inside umbraco (part 1, part 2).

To make it easier to get started, I thought I would provide some starter sourcecode for a demo custom section.

You can download the sourcecode here

Steps to get this running on your umbraco installation:

- Copy the assembly (CustomUmbracoSection.dll) to the \bin directory

- Copy the file custom.gif to \umbraco\images\tray\ directory

- Make a ‘custom’ directory in \umbraco and copy the editCustom.aspx page to \umbraco\custom directory

- Insert a new row in the umbracoApp table

INSERT INTO [umbracoApp]

- Insert a new row in to umbracoAppTree table

INSERT INTO [umbracoAppTree]

- Update the \umbraco\config\create\UI.xml file, add:

  <nodeType alias=”initcustom”>
        <create assembly=”CustomUmbracoSection” type=”Tasks.CustomTasks” />
        <delete assembly=”CustomUmbracoSection” type=”Tasks.CustomTasks” />

After these steps are completed you will have to enable the new section for your user.


Then it should show up as the last icon in the sections (called custom, with a HAL’s camera eye icon).


In the custom section you’ll find this:


So just a sample node that will open a demo edit page.

    Thanks for a great head start.
    I had to insert a row into the umbracoUser2app table to get it working - but now i’m flying

    I can’t get this to work I’m afraid. :(
    I’m using umbraco 4.5.2. My custom area is not added to the UI and if it put breakpoints in my CustomTasks and Tree classes, none of them are hit.

    Is there more documentation on this functionality anywhere?

    Hmm, I just bought a umbraco webTV subscription hoping to get this to work… I did find the solution to my problem in the video, so I thought I’d share…

    I followed the tutorial here but the “custom” node just didn’t appear among the “sections” nodes for my admin user. The trick, as explained in the video, is to force a cache rebuild as the umbracoApp table is cached by umbraco. The way you update the cache is simply to update the timestamp for the web.config, so open the web.config and save it… and voila, the “custom” node appears :-)

    Also, remember to add the section to the needed language files, see e.g.

    BTW: using umbraco 4.7

    I have followed the tutorial but the custom section is not appearing for me. i have cleared the cache and tried but still its not coming. I also noticed that there are some more entries other than default sections in “umbracoApp” and “[umbracoAppTree]” table, those are also not appeared. Please guide me to get this working for me.. Thanks.

    in version 4.11.8 there isn’t ‘umbracoApp’ and ‘umbracoAppTree’ tables, you must do changes in ‘trees.config’ and ‘applications.config’.
