I have a gridview and I used the following code to read the new values when updating data

string test = e.NewValues[3].ToString();

i got the following error.

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

How many columns does your gridview contains ? Remember that an index starts at 0 and not at 1

Perhaps this solves the problem: string test = e.NewValues[2].ToString();

if e.NewValues.Count >= 4 then
    string test = e.NewValues[3].ToString()
end if

Did you try something like this:
e.NewValues["MyColumnName"].ToString()

I tried

string test = e.NewValues["record_name"].ToString();

and got an error saying 'Object reference not set to an instance of an object.'

i ran a test to see how many columns the code thinks is present. I used

e.NewValues.Count

My result equaled 0

Therefore string test = e.NewValues[3].ToString() would never work. I am really stuck on this one!
