I am slowly getting a hang of JSON. At this point I am stuck with the issue of populating a datagrid in VB.NET from a JSON response. The JSON response is something like

{  
   "inventory": [
   {
     "ItemId": 123,
     "category": "A",
     "Description": "xyz",
     "Code": "2",
     "company": "Z",
     "quantity": 5,
     "price": 2.5,
    }
 ]
}

The code I am using is

    Public Class Inventory
        Public Property ItemId As Integer
        Public Property description As String
        Public Property Code As String
        Public Property category As String
        Public Property company As String
        Public Property quantity As Integer
        Public Property Price As Integer
    End Class

 Dim parsedObject = JObject.Parse(response)

        Dim docs = JArray.FromObject(parsedObject("inventory")).Select(Function(x) x.ToObject(Of MyClass.Inventory)())
        Dim invenList = docs.Select(Function(x) x).OrderBy(Function(x) x.description).ToList
       
        myGrid.DataSource = invenList
        myGrid.DataBind()



I am able to populate a datagrid using the code above. Now I need to group by description, code, category and get Sum(Quantity) and Max(Price). How can I modify my LINQ query for that?
