See more:

DashboardEntities dbentities = new DashboardEntities();
           //var List= dbentities.sp_singlecopltable("2");
           GridView1.DataSource = dbentities.singlecobs("2");
           GridView1.DataBind();

I am binding data to gridview in asp .net Using using Entity Framework
for that I have Code on Page Load as above

But it throwing excepton at

GridView1.DataSource = dbentities.singlecobs("2");

Data source is an invalid type.  It must be either an IListSource, IEnumerable, or IDataSource.

What I have tried:

DashboardEntities dbentities = new DashboardEntities();
//var List= dbentities.sp_singlecopltable("2");
GridView1.DataSource = dbentities.singlecobs("2");
GridView1.DataBind();

I'm going to assume that "singlecobs" returns a single object of some type. A GridView is designed to show a collection of objects of a given type, not a single object. The error is complaining that it can't treat the datasource you are giving it as a collection.

If you want the grid to show a single object\row you need to make a collection that contains your single object. There are various ways to do this, but the below makes an array that contains your object.

GridView1.DataSource = new YourType[] { dbentities.singlecobs("2") };

Replace "YourType" with whatever type is returned by "singlecobs".
