Custom Code Tracing & Exception Logging in Dynamics 365 v.9

October 28, 2018

As a Solution Architect I often review Microsoft Dynamics 365 custom server and client side code. One of the most common rejects regards tracing and exception handling mechanisms, or their absence. Some code constructs may have empty Try/Catch blocks or none at all, other catch exceptions and just re-throw. As for tracing, code often contains debugging ‘aids’ such as alerts and debugger statements or no tracing notifications at all. Why is this a reject? Unhandled raw exceptions float to UI, confusing and frustrating users while exposing internal implementation details to potential attackers System Administrator is unaware of custom code exceptions unless users decide...

Drag & Drop File Upload Revisited

October 18, 2018

Finally found the time for overdue maintenance on the Drag & Drop solution I created two years ago. Why revisit? First of all, as the CodePlex platform, previous home of this solution, is being decommissioned, downloading the component got the whole CodePlex project and few visitors commented that they could not find the actual solution. So now you can download an unmanaged solution from it’s  new home @ Github. Second, I fixed a major bug related to the plural name of some entities. For most entities, appending ‘s’ to the entity schema name would result in the matching entity name for Web API. Some...

Microsoft Portal – Retrieve Dynamics 365 Data Asynchronously – Part 2

October 15, 2018

In part 1 of this post I demonstrated building and using a service which receives a FetchXML query and returns Dynamics 365 data to any Portal page in an asynchronous manner as a JSON object. This service is similar to the SDK’s RetrieveMultiple message. In this part 2, I’ll demonstrate a different service, which like the SDK Retrieve message, receives a record type, record id (GUID) and columns set to return the required data as a JSON object. This is useful when you already have a specific Dynamics 365 record id at hand and you want to retrieve additional data for...

Microsoft Portal – Retrieve Dynamics 365 Data Asynchronously – Part 1

October 12, 2018

Leveraging Colin Vermander brilliant article on using Liquid Templates to return JSON, I would like to demonstrate creating and using a ‘service’ to asynchronously retrieve Dynamics 365 data into any portal page. Why is this useful? Liquid Templates tags are rendered on server side before a response is returned to the browser, so FetchXML tag will return a static result once the page is returned. But what about responding dynamically to client side events such as option selection, button click or expending an element to view more details? Sending the page to the server again is no longer an option if you want...
