Instead of binding a whole collection to a grid, I want selected fields to be bound. E.g. Northwind database/ Order Details ( havin 5 rows / fields) I want to bind only 3 fields.

How is that been done. I couldn't find a hint in your samples code

It dependsd if you are developing a web or windows application.

In windows app: define tableStyels and GridColumnStyles ofr the datagrid in hand. In Web app: you should manually define asp:BoundColumn(s) inside the <Columns> tag or visually by using the columns collection property of the datagrid.

You can also go for a typedList or dynamicList instead of using the entityCollection. Where you can select specific fields to be added to the lists.

Sorry, I didn't describe correctly.

I am developing a windows applikation. All what i need is 3 columns out of n, which are in the collection. Is there any way as a sort of SELECT col1, col2, col3 FROM Collection

All you have to do is to work with the Grid's "TableStyles" property, define a tableStyle and add the columns (which map to fields) you want, you may choose not to add a field or to add it and have it hidden.
