DataGrid Grouping when binding to class that contains collections of other classes.

[Ashley]

Hi,

I have a data structure similar to the one below where one class contains a colleciton of another class as one of it's fields:

Product
{
    String name
    String desription
    Address[] addresses
}

Address
{
    String state
    String suburb
}

Within a data grid which I am binding to the Product class, I want to display only the Product "name" field but have it grouped by the "state" field of the first item of the addresses collection (within my data I am ensuring that every Product has at least one Address)

So my data grid would look somthing like:

VIC
    - Product Name 1
    - Product name 2
NSW
    - Product Name 3
    - Product Name 4

Is this possible? To date I can only get grouping working on fields within the Business (or top level) class, not fields from the Address (or nested) class.

Hello Ashley,

I am sorry to say that the current implementation of the RadGrid does not support this kind of logic. You can achieve your goal using many-to-many relational database and a hierarchical structure. To get an idea for the practical realization you could take a look at the following post.
