Fetching MySQL Data and Populating ComboBox in C#


In C# applications, integrating data from a MySQL database into user interface components, such as a ComboBox, is a common task. This tutorial aims to demonstrate the process of connecting to a MySQL database, retrieving information from the “genres” table, and displaying it within a ComboBox.

Establishing Connection:

The code snippet begins by establishing a connection to a MySQL database using the MySqlConnection class. The connectionString variable contains the necessary connection details, such as server name, credentials, and database name.

Fetching Data from MySQL Table:

A SQL query is formulated to retrieve all records from the “genres” table in the database.

A MySqlCommand object is created with the SQL query and the MySqlConnection instance to execute the query against the database.

Populating ComboBox:

A ComboBox (cmbGenre) in the C# application is designated to display the retrieved data.

The ‘ValueMember’ property is assigned the column name “genre_id” from the DataTable, representing the value for each ComboBox item.

Similarly, the ‘DisplayMember’ property is set to “genre_name,” representing the visible text for each ComboBox item.

Error Handling:

The try-catch block is used for error handling, ensuring that any exceptions during database operations are caught and displayed as a MessageBox for user notification.

C# Code:

This tutorial outlined the process of fetching data from a MySQL database table named “genres” and populating it into a ComboBox in a C# application. Understanding database connectivity and data retrieval mechanisms is fundamental for developing interactive and data-driven applications in C#.
