💡 X++ Tip: Keep the Same Record Selected After Refresh in a Form or Data Source

 When you refresh a form data source in Dynamics AX or Dynamics 365 for Finance and Operations, the current selection is often lost — the cursor jumps back to the first record. This can be frustrating, especially if you want the user to remain on the same record after an update or refresh. Here’s a simple and reliable way to restore the cursor to the same record after the data source is refreshed. 🧩 Scenario Suppose we have a form displaying records from MyTable . When we refresh the data source — for example, after updating a field or calling executeQuery() — we want the form to return to the same record the user was viewing before the refresh. ✅ Solution: Use ds.cursor() We can achieve this using a record buffer and the cursor() method of the data source. public void refreshDataSource() { MyTable myTableRec; // buffer to store current record // Store the current record myTableRec = MyTable_ds.cursor(); // Refresh the data source MyTable_ds.r...

Introduction to X++ Variables

 X++ is a high-level programming language used primarily in Microsoft Dynamics 365 Finance and Operations. Understanding how variables work in X++ is fundamental for managing data and performing various operations within the ERP system. What is a Variable? A variable in X++ is an identifier that points to a memory location where data of a specific type is stored. The characteristics of a variable, such as size, precision, default value, and range, depend on its data type. Variables are crucial for storing and manipulating data during the execution of a program. Variable Scope The scope of a variable defines where it can be accessed within the code: Instance Variables : Declared in class declarations and accessible from any method within the class or its extensions. Local Variables : Declared within a method and can only be accessed within that method. Declaring Variables When you declare a variable, memory is allocated, and the variable is initialized to its default value. Variable...

Introduction to X++ (Detailed X++ Language Reference)

  Introduction to X++ X++ is a high-level programming language designed for enterprise resource planning (ERP) systems and database applications. It combines object-oriented, application-aware, and data-aware paradigms to facilitate complex business process management and data manipulation. Key Features of X++ Classes : System Classes : Provide core functionalities, such as file handling, collections, and data manipulation. Application Classes : Manage various business processes specific to ERP systems. Reflection : Allows introspection of classes to dynamically access properties and methods at runtime. Tables : Access to Relational Tables : X++ allows direct interaction with database tables using syntax similar to SQL. Keywords : Includes keywords for data definition and manipulation, akin to SQL. Reflection : Supports introspection on tables for dynamic access to fields and methods. User Interface : Forms and Reports : X++ provides the ability to create and manipulate UI elements...
