Question

I have the following Data Structures:

List<Customer> currentCustomers {...}

public class Customer 
{
    public string ID { get, set }
    public string Name { get, set } 
    [...]
    public List<Products> { get, set } 
}

I have a customers DataGrid bound to the currentCustomers List.
What I would like to be able to do is bind a second DataGrid to the selected item within customers to display all the Product information for that Customer.

i.e. The user clicks on a Customer within the Customers DataGrid, this then automatically updates a second DataGrid based on that Customers Products.

Is this even possible?

If so, is there a resource around that will tell/show me how this is done?

Answer 1

Just bind it to SelectedItem property:

<DataGrid x:Name="customersList" CanSelectMultipleItems="false" ... />

<DataGrid x:Name="customerDetails" 
          ItemsSource = "{Binding ElementName = customersList, 
                                  Path = SelectedItem.Products}">
