I've posted this yesterday on asp forum but no one replied so perhaps I'll have better luck here.

For some reason the OnUpdating method does not pull new values from the grid which is in edit mode. I've search and have come across several blogs and sites, some sugesting that an ObjectDataSource is required in order to use the "e.NewValue" construct others provide code to the contrary.

I don't get any errors - the variables in the code file would contain the old values rather then new ones.

I don't want to use the ODS way of manipulating the data. My delete method works but not the update one. Can you suggest what is wrong with the code? Here is what I've got:

aspx file:

<asp:GridView ID="gvBlack" runat="server" AutoGenerateColumns="False" OnRowUpdating="gvBlack_OnUpdating" OnRowEditing="gvBlack_RowEditing">
