Simultaneous Binding to Multiple Data Sources

The .Net Grid enables simple connection to different data sources simultaneously. The component model has IListSource interface that enables objects to return a list that can be bound to a data source. In the following example the grid uses this interface to bind multiple data sources.

public class MultipleDataSources : IListSource
{
    private readonly IList _listSource = new ArrayList();

    public IList GetList()
    {
        return _listSource;
    }

    public bool ContainsListCollection
    {
        get { return true; }
    }
}

public void PopulateGrid(Grid grid)
{
    BindingList<Order> orders = new BindingList<Order>();
    //Populate orders...

    BindingList<Strategy> strategies = new BindingList<Strategy>();
    //Populate strategies...

    //Combine multiple data sources in the MultipleDataSources object
    MultipleDataSources multipleSources = new MultipleDataSources();
    multipleSources.GetList().Add(orders);
    multipleSources.GetList().Add(strategies);

    //Bind the grid to datasources
    grid.DataSource = multipleSources;
}
