WinForms DataBinding to Objects - What is the equivalent to a DataRelation for allow navigation of Parent/Child Relationships?

Question

WinForms databinding has very solid support for navigating related DataTables via DataRelation objects, but I'm having a difficult time finding resources for implementing similar functionality for databinding against a business object.

Does anyone know of an equivalent to the DataRelation object, or know of any resources on implementing equivalent functionality, for databinding to an object with related items?

Answer 1

If I understood you correctly and you are looking for kind of master-detail BO relations I think you can find tip in my post you already answered :)

    // create binding sources
    BindingSource bs1 = new BindingSource(Persons, null);
    BindingSource bs2 = new BindingSource(bs1, "Parents");

    // bind to grid
    dataGridView1.DataSource = bs1;
    dataGridView2.DataSource = bs2;
