CRUD application using C#, PostgreSQL, Windows Forms

Download Visual Studio 2022 Community and the PostgreSQL Windows installer, noting 64-bit preference and that 32-bit Windows supports up to version ten, then install and configure both.

Configure a PostgreSQL server for a C# Windows Forms CRUD app, create a dedicated user with minimal privileges and a database, and connect via pgAdmin.

Configure Visual Studio 2022 for a C# Windows Forms CRUD app with PostgreSQL. Install System.Configuration and PostgreSQL helpers, and add an app config with a local host connection string.

Configure a PostgreSQL server for the app by creating a dedicated database and a non-superuser, with limited privileges, using pgAdmin to manage servers, logins, and roles.

Set up a Visual Studio 2022 Windows Forms project with .NET 6, add app config via NuGet for PostgreSQL 14 access, and configure a connection string and helper classes.

Pull a PostgreSQL connection string from app.config into C# code, configure a data grid view, and double-click a row to populate text boxes for CRUD operations in Windows Forms app.

Learn to create a PostgreSQL table using both the graphical interface and SQL scripts, defining a serial primary key, varchar fields, and a text column while exploring schema and constraints.

Create a table and a stored procedure to insert data. Then call the procedure, commit the transaction, and verify the inserted records with a select query.

Learn to read records from a PostgreSQL database into a Windows Forms DataGridView using C# and the PostgreSQL data provider, with using blocks and error handling.

Advance the Windows Forms CRUD interface by dragging labels, text boxes, and a data grid view into place, and follow the documented naming convention to keep controls consistent.

Build a practical user interface for a CRUD application using C# and Windows Forms, connected to PostgreSQL, and apply UI design principles in a hands-on no-sound lecture.

Explain the user interface and naming conventions for controls, including the search area, the data grid, text boxes, and buttons used for create, read, update, and delete.

Adjust the user interface by refining the main form, hiding the control box, centering the startup position, and implementing a quit confirmation dialog using a message box with yes/no options.

Populate all textboxes by double-clicking a data grid view row, extract current row values, and populate each textbox to support create, read, update, and delete operations.

Implement a compact clear text boxes method for a Windows Forms CRUD app, wiring a clear button to reset all text boxes using a for-each loop.

Learn to save records in a C# Windows Forms CRUD app using PostgreSQL by collecting textbox data, building an insert query, and executing it with database connection and error handling.

Update a record in a C# PostgreSQL Windows Forms CRUD app using the data grid view, update statement, and record id, then refresh the grid and show a confirmation message.

Learn to implement delete functionality in a C# PostgreSQL Windows Forms CRUD app: confirm deletions with a dialog, remove the record by id, and refresh the data grid view.

The lecture builds a complete CRUD application in C#, PostgreSQL, and Windows Forms, illustrating inline SQL, later transitioning to stored procedures, and managing UI state for create, read, update, delete.

Explore the business logic for a Windows Forms CRUD app, wiring textboxes and buttons to create, read, update, and delete records, refresh the data grid, and manage field states.

Manage button states in a C# Windows Forms CRUD app by toggling new, save, clear, delete, and quit based on text box conditions.

Implement the update workflow in a windows forms CRUD app with C# and PostgreSQL, enabling update on selection, populating fields from the data grid, and handling clear and delete states.
