Eval Vs Bind Asp Net

Eval vs Bind in ASP.NET

When you start working with ASP.NET, sometimes it’s difficult to understand what is the difference between Eval and Bind for data binding controls in ASP.NET.

If you need to display data on the screen from DataSource, it’s enough to use Eval. It’s something like a read-only method from DataSource.

But if you need to edit data inside of the grid, you have to use the Bind method because it provides two-way binding. You can read data from DataSource, and you can write data back. Usually, you have to use this method if you need to quickly develop a WebPages and display and edit data from one table or simple view.

If you try to modify some rows in Data Grid and want to make changes in the code-behind class (OnUdpdating event), data with the Eval method will not be available instead of the Bind method.
