Question

I was searching for reusable Grid for MVC .Net. I found one open source Grid.

In the code I found a pretty interesting class declaration which I didn’t understand
.
Can anybody tell me a detailed description of class declaration below:

public class Grid<TEntity, TSearchForm> : IGrid where  TSearchForm : SearchForm, new()
{
}

Also how do I create an instance of this class?

Answer 1

The class is a generic class, it implements IGrid.

The two generic type parameters are TEntity and TSearchForm.

TSearchForm is constrained to be SearchForm or a type that inherits from SearchForm and that it has a default constructor.
