Safely Handling AliasedValue in Dynamics 365 Plugins

Developing plugins for Dynamics 365 often involves extracting and manipulating data from linked entities using FetchXML. One common challenge in this scenario is handling the AliasedValue objects that Dynamics 365 returns when querying attributes from these linked entities.

Enhancing Dynamics 365 Plugin Reliability with Specific Exception Logging

When developing plugins for Dynamics 365, handling exceptions robustly and providing clear, actionable error messages can significantly improve the maintenance and usability of your solutions. This article discusses a practical tip for logging specific exceptions to streamline troubleshooting and enhance system reliability.

Optimizing Large-Scale Data Updates in Dynamics 365 with Asynchronous Plugins and Flexible FetchXML

Introduction

In Dynamics 365, it's not uncommon to encounter scenarios where vast quantities of records require updates or complex manipulations. Naively processing large volumes in a single operation can strain performance and lead to timeouts. This article presents a strategy to tackle such challenges, emphasizing asynchronous processing, plugin chaining, and flexible FetchXML-driven initiation.

Understanding Relationship Types in Dynamics 365: N:N vs. 1:N & N:1

When modeling data relationships in Dynamics 365, understanding the distinction between N:N (Many-to-Many) and 1:N & N:1 (One-to-Many & Many-to-One) relationships is crucial. These relationship types serve different purposes and have unique characteristics.

Dynamics 365 Data Retrieval: Comprehensive Guide

Retrieving data effectively in Dynamics 365 (D365) is crucial for custom solutions' performance and scalability. This article explores different methods for data retrieval - QueryExpression, FetchXML, RetrieveMultiple, and direct record retrieval, providing complete sample codes for each scenario and a comparative analysis to help choose the right approach for specific needs.

Integrating Client-Side Scripts with Server-Side Plugins in Dynamics 365

Introduction

Integrating front-end actions with back-end server plugins in Dynamics 365 allows for robust process automation and enhanced user interaction. This article presents a generalized approach, showcasing a client-side script that triggers a custom action, subsequently invoking a server-side plugin for comprehensive business logic execution.

Pagination Methods in Dynamics 365 Integration: An In-Depth Guide

Introduction

When working with Dynamics 365, especially when integrating it with other systems, you'll often have to retrieve large sets of data. However, due to performance considerations, APIs usually impose a limit on the number of records you can fetch in a single request. This necessitates the use of pagination to get the entire dataset. This guide aims to provide a comprehensive understanding of different pagination methods, their advantages and drawbacks, and how to apply them in Dynamics 365 integration scenarios.

    var tabContext = formContext.ui.tabs.get("tab_Bed_Assignment"); // get the tab context by its name
 
    // Register the event handler for the tab's state change event
    tabContext.addTabStateChange(filterSubgridBedAssignments);
    filterSubgridBedAssignments(executionContext);
 
    
   
}
 
function filterSubgridBedAssignments(executionContext)
{

    var subgrid = formContext.getControl("subgrid_BedAssignments");

What's the $ in front of a string in C#?

`What's the $ in front of a string in C#?`

Reference

$ is short-hand for String.Format and is used with string interpolations, which is a new feature of C# 6. As used in your case, it does nothing, just as string.Format() would do nothing.

What's the @ in front of a string in C#?

Reference

It marks the string as a verbatim string literal - anything in the string that would normally be interpreted as an escape sequence is ignored.
