Welcome to the FoxLearn
Today we will learn how to export datagridview to text file
First, You need to create a simple UI that allows you to receive product data from the northwind database, then export data from datagridview to text file
A text file is a kind of computer file that is structured as a sequence of lines of electronic text
A text file exists within a computer file system
The end of a text file is often denoted by placing one or more special characters, known as an end-of-file marker, after the last line in a text file
We will use entity framework to retrieve data from the product table in the northwind database
Entity Framework is an object-relational mapper that enables .NET developers to work with relational data using domain-specific objects
It eliminates the need for most of the data-access code that developers usually need to write
You can download the Northwind database below this video
You can use Progress Bar and BackgroundWorker to handle export data
The BackgroundWorker class allows you to run an operation on a separate, dedicated thread
Time-consuming operations like downloads and database transactions can cause your user interface to seem as though it has stopped responding while they are running
When you want a responsive UI and you are faced with long delays associated with such operations, the BackgroundWorker class provides a convenient solution
To set up for a background operation, add an event handler for the DoWork event
Call your time-consuming operation in this event handler
To start the operation, call RunWorkerAsync
To receive notifications of progress updates, handle the ProgressChanged event
To receive a notification when the operation is completed, handle the RunWorkerCompleted event
