# What is difference between Eval() and Bind() method in Asp.Net?

The difference between Eval and Bind is that Eval function is used to bind data to control inside a DataBound control, but it cannot update the values back to the database.

On the other hand, Bind function can be used to bind data to control inside a DataBound control and also it can update the values back to the database.

But the above explanation did not give me clear idea and hence I wrote two examples in order to illustrate the functioning Eval and Bind functions in ASP.Net.

## There are basically two difference in between them...

**Eval()** is Unidirectional where as Bind() is Bi-Directional.

**Eval()** can combine more than two filed where as Bind() cannot do this Operation.

Eval is used for unidirectional (readonly) data binding, while Bind is for bi-directional (editable) databinding.
