Render 'object in object' in DataGridView ?

[deisler]

I have a generic list List<Order>, in which Order object has some common property such as OrderId,TotalValue and property that map to another object, called Customer{CustomerId, CustomerName}. Snippet of code for clarification :
class Order
{
string OrderId; // Property
double TotalValue; // Propery
Customer CustomerOnSign; // Property

}
class Customer
{
string CustomerId; //Property
string CustomerName; //Property
}

Now I want to populate List<Order> to DataGridView.Datasource and when I try to render Customer column, I set the column's DataPropertyName = "CustomerOnSign.CustomerName" it seems to appear nothing in the grid. If I set the DataPropertyName = "CustomerOnSign", it only appears the Customer object name but not the CustomerName property, which I want.

Just want to know is there any way to overcome this prob ? Any help is highly appreciated.

If you want to use the object you can override its ToString() method of the Customer class like

public class Customer{
private string customerName;
....

public override string ToString(){
this.CustomerName;
}
// The Properties needs to look like this one
public string CustomerName{
get{ return this.customerName;}
set {this.customerName = value;}
}
Have you dtried to debug and looked if your class is correctly filled with data ?
