Today, I was working on a v8 to v13 upgrade project, and I realised that I couldn't access my [HttpPost] actions in a SurfaceController from an Ajax POST call. After trying some solutions without any luck, including Route attributes to the SurfaceController and actions, I found out that starting from Umbraco v9, the SurfaceControllers have the anti-forgery check by default as SurfaceControllers are primarily made for POSTing forms within Umbraco.  To resolve this issue, I added the following  beforeSend bit to my Ajax call and also added the [ValidateAntiForgeryToken] attribute to my actions in my SurfaceController. During tests, I also realised that I could ignore the anti-forgery token completely by adding the [IgnoreAntiforgeryToken] attribute to my actions, but this is not an option that anybody should go for as this option skips the anti-forgery token validation and makes your website more vulnerable for things like Cross-site request forgery attacks.   $ . ajax...

 As part of my job, I get involved in quite a few Umbraco upgrade projects, and recently, after upgrading an Umbraco v8 project to the latest LTS version of Umbraco (v13), I saw a new error which blocked a piece of content from being rendered correctly.  Problem The problem was happening with one Special CTA content block and all other blocks were looking good.  System.InvalidOperationException: Sequence contains no matching element    at System.Linq.ThrowHelper.ThrowNoMatchException()    at System.Linq.Enumerable.First[TSource](IEnumerable`1 source, Func`2 predicate)    at Our.Umbraco.DocTypeGridEditor.Helpers.DocTypeGridEditorHelper.ConvertValue(String id, String contentTypeAlias, String dataJson)    at Our.Umbraco.DocTypeGridEditor.Helpers.DocTypeGridEditorHelper.RenderDocTypeGridEditorItem(IViewComponentHelper helper, IHtmlHelper htmlHelper, Object model)    at AspNetCore.App_Plugins_DocTypeGridEdito r_Render_DocTypeGr...

Umbraco is a highly flexible, open-source content management system (CMS) that allows developers to easily build powerful websites. Hosting Umbraco websites on Microsoft Azure provides numerous benefits, such as scalability, security, and seamless integration with other Azure services.  In this guide, we’ll explore one of the recommended architectures for hosting an Umbraco website on Azure, including key services, configurations, and best practices to ensure performance, reliability, and ease of management. Architecture Diagram and Breakdown of Primary Azure Components Microsoft Azure is a robust cloud platform with a broad set of services that align well with the needs of a modern web application. Azure can offer hosting, storage, monitoring, security, and automatic scaling for an Umbraco website, among other features. With the right architecture, Azure enables Umbraco websites to serve traffic seamlessly, adapt to changing loads, and provide a secure environment for content ma...

Briefly Examine and Lucene Examine  is a powerful tool that simplifies data indexing and searching. It was developed by Shannon Deminick and operates on top of  the Lucene.Net Search Engine Library , which is a high-performance search library designed for .NET applications.   Examine is highly extensible, allowing users to configure multiple indexes, each with its own settings. By default, Examine provides a Lucene-based index implementation along with a Fluent API for easy data searching.   Additionally, Umbraco offers a layer known as UmbracoExamine , which provides Umbraco-specific APIs for indexing and searching content and media. The Umbraco backoffice utilizes the same search engine to return results for content, media, and various Umbraco settings, including Document Types, Data Types, and Dictionary Items. Umbraco stores all values in Examine as Strings By default, Umbraco stores all search index values as strings. This creates a significant issue when you ne...

A few years ago, I created this blog post to show how to find Umbraco v7 Nodes using a certain Umbraco Document Type.   I needed the same thing for Umbraco v8 projects, and below are some scripts that should help with this question. Find content pages that use a specific document type:  SELECT * FROM umbracoContent C INNER JOIN cmsContentType CT ON C . contentTypeId = CT . nodeId INNER JOIN umbracoNode N ON C . nodeId = N . id WHERE CT . alias = ' YourDocumentTypeAlias ' Find the latest published version of a content page by content page node id:    SELECT pt . alias , pd .* FROM umbracoPropertyData as pd INNER JOIN cmsPropertyType as pt ON pd . propertyTypeiD = pt . id INNER JOIN umbracoContentVersion as cv ON pd . versionId = cv . id WHERE cv . NodeId = 1055 and cv . [current] = 1

SOLID software design principles are guidelines that help developers create more maintainable, understandable, and flexible code. These principles apply to any object-oriented design, and they aim to reduce the complexity of software development, making it easier to manage and scale.  The acronym SOLID stands for: Single Responsibility Principle (SRP): A class should have only one reason to change, meaning it should have only one job or responsibility.         Example: Instead of one class handling multiple responsibilities (calculating, printing, saving), each class has a single responsibility.        public class Invoice  {          public void CalculateTotal() { /* ... */ }     }       public class InvoicePrinter  {         public void Print(Invoice invoice) { /* ... */ }     }     ...
