Getting values from textbox in a datagrid

I have a Datagrid with five Columns

Serail
Product
Price
Qty(textbox)
Order(Button)

now i want user to enter the Qty and clicks order for that column i shud get Text entered in the qty and Serial of the Product

can please nay one help me out

i don't want to put another button or link for edit and update

Qty field is not in the database

I'm assuming you're already handling the button click event?

PHP Code:

---

//Get the integer counter number for the row whose button was clicked

Then, 

TextBox txtQty = (TextBox)dgGridName.Items[counter].FindControl("txtQuantity"); 


---

txtQty.Text will then give you the value.

I Am Using Asp.Net If anyone can halp me in this

Am I invisible? :confused:
