ASP.NET Datagrid problem

Having a problem using the Datagrid editing functions (ASP.NET)

Basically, i'm using the following code to update the datasource with the inbuilt editing functionality of the datagrid.
(function for on_Update)

ds = (DataSet)Session["Source"];
DataRow row;
row = ds.Tables[0].Rows.Find(dgRejectGrid.DataKeys[e.Item.ItemIndex]);

int UserTimeID = int.Parse(row.ItemArray[0].ToString());
TextBox RejectNotes = (TextBox)e.Item.Cells[2].Controls[1];

string str = RejectNotes.Text;

Basically the control is found that isn't the problem, the only problem is the RejectNotes.Text always returns as empty string "".
I'm using the exact same code somewhere and it works fine!  
I've setup the textbox correctly with the correct databindings.
DataBinder.Eval(Container, "DataItem.AuthRejectText")

I've deleted the datagrid and started again but i get the same problem.

Any ideas?

what exactly returns  (TextBox)e.Item.Cells[2].Controls[1] ?
does ((TextBox)e.Item.Cells[2].Controls[1] ).Text is also empty?
if it is try this

TextBox RejectNotes = (TextBox)e.Item.Cells[2].FindControls("yourtextboxid");

(TextBox)e.Item.Cells[2].Controls[1]   returns  'Textbox'

and yes ((TextBox)e.Item.Cells[2].Controls[1] ).Text  returns an empty string

the last suggestion i've also tried which doesn't work.  

Don't understand...

can you post the code you use in your html

may be you can try to use this
DataBinder.Eval(Container.DataItem, "AuthRejectText") ( if AuthRejectText is your field's name )

What should i use as the first param of DataBinder.Eval?  

C:\Inetpub\wwwroot\TimeManagement\RejectTime.aspx.cs(109): 'System.ComponentModel.Container' does not contain a definition for 'DataItem'

When do you receive this error? when you type
this :
<%# DataBinder.Eval(Container.DataItem,"AuthRejectText") %>

or this :
<%# DataBinder.Eval(Container,"DataItem.AuthRejectText") %>
??

By the way look you use <%# DataBinder.Eval(Container.DataItem,"AuthRejectText") %> in the template of the current column. Other way you don't have DataItem object
