I have a working WebDataGrid that updates and deletes correctly.  I added the RowAdding behavior to the WebDataGrid <ig:RowAdding />.  Now when I visit the WebDataGrid I Double Click on the grey row and begin adding the data into each cell then hit enter it gives me a very long error.

Asycn request failed

[NullReferenceException]: Object not set to an instance of an object.

Here is my grid

<ig:WebDataGrid ID="dgvStaff" runat="server" Width="100%"
EnableDataViewState="True" DataKeyFields="stfGID" ClientIDMode="Static"
AutoGenerateColumns="False" onrowsdeleting="dgvStaff_Deleting"

Any idea what I am missing here?
