I have had a look at the tutorial "VS.NET: Design time databinding with windows forms"

I am using Infragistics Grid and I would like to display parent and child rows in the same grid.

If I dynamically bind the grid's datasource to a DataAccessAdapter it works ok.

How can I use an entity collection at design time which requires prefetched data?

I tried the following in the form load event handler

    private void Form1_Load(object sender, EventArgs e)
    {
        PrefetchPath2 CommsPath = new PrefetchPath2((int)EntityType.CasesEntity);
        CommsPath.Add(CasesEntity.PrefetchPathCommunicationsLog);
        adapter.FetchEntityCollection(entityCollection1, null, CommsPath);
    }

seems to work ok. Still feels like I am flying half blind.

You've got it right.
