Gridview - OldValues collection from ExtractValuesFromCell method contains NewValues

[lightgram]

Hello

I am having problems extracting the OldValues collection from the RowUpdating event in my GridView.

Every time I access this I am getting the values from the NewValues collection in both OldValues and NewValues. I am fairly sure that the data is not being rebound prior to the updating event.

I have posted my code below.

Thanks in advance.
