How to use aggregate on nested members

[Katie]

Hi, 

I am using telerik rad gridview to display customers. My customer object have another class as a property. 

So the object looks like: 

public class Product
{
public int ProductID {get; set;}
public decimal Amount {get; set;}
public string ProductName {get; set;}
}

public class Customer
{
public int CustomerID {get; set;}
public Product CurrentProduct {get; set;}
public string FirstName {get; set;}
public string LastName {get; set;}
}

 
Now I binding a list of customers to the grid and displaying Product Info too. But how do I do an aggregate function? Normally I would put Amount as the source field for the function.

Hello,

 You could try to create your own custom aggregate function. Please refer to the custom aggregates example in the wpf demos or to this online example.  

All the best,
