Binding Grid to a sub class property

[Alessandro]

I am binding a grid to a list of objects such as:

ObservableCollection<ListItem> List

Wherby the ListItem is defined as:

public class ListItem
{
  public int Id;
  public string Title;
  // some other properties
  public Item TheItem;
}


the class "Item" is defined as:

public class Item
{
   public string Name;
   public string Location;
   public string Brand;
   public string Area;
}

Question 1

  I am binding my grid to the List of ListItems and therefore want to show its properties. I also want to show properties of the Item class it contains. My thinking is that the only way to do this is to dynamically construct the columns and bind them programatically. Am I correct in this thinking?

Question 2
 
  I am using a selector for specifing the detail panes. These Detail pains are setup to bind to an Item class, NOT to a ListItem class (this is becuase I reuse the usercontrol elswhere). Can I modify the binding of the Detail item so that it does not bind to the default ListItem (to which the grid items bind) but rather to a contained object of the ListItem? How and where would I do this? Thanks for all your help!

Hello Xavier,

You can bind the columns easily by using:

DataMemberBinding={Binding Item.Name}
DataMemberBinding={Binding Item.Location}, etc.

As for question 2 - do you mean the Row Details? If so, I am afraid this is not possible. The DataContext of the details presenter would be of type ListItem and you cannot change that. So, you could use the same Binding as the columns in this case.

Kind regards,

hi Veselin,

With your example below:
DataMemberBinding={Binding Item.Name}
DataMemberBinding={Binding Item.Location}, etc.

I am noticing if I do this, then these two columns are no longer sortable, and we can not filter them either. Is this a known functionality? What is the workaround? Please advice.

Thanks.

Yes.

Hi,

I've made a small project in order to reproduce the issue but sorting and filtering work as expected. Can you confirm that your scenario is the same? Is there something specific that I have missed?
