Why Use BindingList Instead of List When Binding to a DataGridView in WinForms?

Binding BindingList to DataGridView in WinForm

Problem:

When using a List to bind to a DataGridView, the DataGridView does not automatically update when new items are added to the list.

Solution:

To resolve this issue, bind the DataGridView to a BindingList instead of a List, as BindingList implements the IBindingList interface.

Code:

var list = new BindingList<Person>(persons);
myGrid.DataSource = list;

Benefits of BindingList:

• Reactivity: BindingList automatically notifies the DataGridView of any changes made to its underlying collection, ensuring that the DataGridView is always displaying the most up-to-date data.
• Additional Features: BindingList provides additional features such as sorting, filtering, and searching, which can be useful for data manipulation within the DataGridView.

Advanced Binding:

For even greater flexibility, consider using a BindingSource to bridge between the BindingList and the DataGridView. This allows for additional customization and control over the data binding process.

var list = new BindingList<Person>();
var source = new BindingSource(list, null);
grid.DataSource = source;
