Update/insert from GridView

Gridview

i have worked with grids and datasets with no problems, but i am struggling with binding the results from the WCF object so i can update/insert a row/rows using a gridview. Is this even possible? from what i have been researching, it is, I have not found any good examples similar to the following situation.

I have tried using the BindingSource and other list objects, I have also noticed that there is no value for the Datamember property to set using an object, or is there? as of now the grid loads with the data but i can do no editing.

part 1

<ServiceContract(), XmlSerializerFormat()>
Public Interface IIncedentNotifications

    <OperationContract()>
    Function GetCurrentIncedents() As List(Of IncedentNotificationsData)
    Function InsertIncedent(ByVal incedent As IncedentNotificationsData) As Byte

End Interface

    'Create a data contract first
    <DataContract()>
    Public Class IncedentNotificationsData

    <DataMember()>
    Public Property IncedentDescription As String
    <DataMember()>
    Public Property IncedentDateTime As DateTime
    <DataMember()>
    Public Property Resolved As Boolean

    End Class

Private Sub LoadIncedentGrid()

    Try
            binding.DataSource = incedentService.GetCurrentIncedents()
                binding.DataMember = "Incedents" 
                IncedentGrid.DataSource = binding.DataSource
