Forms Data Controls :: "compare" Control (TextBox) Values In Two Different GridViewRows?

I have a gridview which has TWO rows (assume this will always be the case). The grid is set in a way that whenever "Edit" is clicked, whole gridview turns into edit mode. (I mean all the rows)
Name
Age
earth
1

<<Edit>>
<<Update>>

In the GridView, I show the quantity in a text box and handle the OnTextChanged event for that textbox. Now the problem, is how can I keep the changed quantity text in session or view state, and in which row, so that I can update my GridView and bind that data again to the GridView?

When attempting to place controls in different content areas using Masterpages and trying to use a compare validator, I get the error: Unable to find control id 'txtStartDate' referenced by the 'ControlToCompare' property of 'cvlDate'. I have also attempted to set it within the c# code behind in page load: cvlDate.ControlToCompare = txtStartDate.ID and by using findControl there must be an easy way to achieve this?
I would rather specify fields in my code behind than embedding them in the .aspx page.
I also have a subtotal label control in my repeater that I would like to populate its text property by mutiplying two of the database values e.g productprice * unitprice shown in my repeater.
I need to do this in code behind, looping through the repeater. Any idea of how I can do this in C#?

I have a ListView control that makes use of a DataPager. In each row of the ListView there is a text box where the user will enter some notes relevant to that particular record. Then they use the DataPager to navigate to the second page of records. If they then return back to the first page in the ListView the text they entered is gone.
Question: Is there a way (through use of a paging event or databound event maybe?) to retain the textbox values between paging events ?
I would like the user to be able navigate backward or forward and still see the text heshe has entered.
