How to implement IDataSource interface for a custom generic collection in C#

Question

Hello All:

I am using DataView in SharePoint. I want to bind a collection of objects to the DataView. But when I am trying to bind it is giving the error that the collection does not implement IDataSource interface. Can anybody tell me how to extend the collection class to implement IDataSource interface?

Thanks Ashwani

Answer 1

An interface is a public contract- implementing an interface means that the class implements each of the methods declared in the interface. Your collection class will have to be defined as implementing IDataSource:

public class MyClass : IDataSource

and then implement each IDataSource method:

DataSourceView IDataSource.GetView(string viewName)
{
//your code here
}
...etc.

See MSDN for more details
