re: Binding the GridView control to a complex (deep) business object

The easiest way to do this is to extend the BoundField and provide your own implementation for GetValue

For Example:

public class EnhancedBoundField : BoundField

{

protected override object GetValue(Control controlContainer)

{

object component = null;

string dataField = this.DataField;

if (controlContainer == null)

{

throw new HttpException("DataControlField_NoContainer");

}

component = DataBinder.GetDataItem(controlContainer);

if ((component == null) && !base.DesignMode)

{

throw new HttpException("DataItem_Not_Found");

}

// use reflection to get the data from your child...

}

Remove the "[" "]" from the property name ([City.name]) and it work.

By the way, nice post dude.

Now I found another problem...

How can I set this same property AssociatedProduct.Name as a DataKeyName?

Thanks.

Well, in your grid view should write as bellow:

<%# DataBinder.Eval(DataBinder.Eval(Container.DataItem, "AssociatedProduct"), "Name")%>

please try..
