Question

I have an asp:DetailsView with several columns, e.g. Foo, Bar.

I want to fill it with an anonymous type, i.e.:

gridView.DataSource = new { Foo = 1, Bar = "2" };
gridVeew.DataBind();

But getting next error:

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

How can I do what I want?

Answer 1

The DataSource property expects a collection. The value you are assigning is not a collection.

You will have to create a collection and put the anonymous typed instance into that collection. The following should probably work (though I’ve not tested it with DataSource):

gridView.DataSource = new[] {new {Foo = 1, Bar = "2"}};
