How to capture data on form without submit button 2

[jupiter8]

I am writing a shopping basket and want to basket total to be updated everytime someone changes the quantity without having to click on a 'update basket' button.

So I have made 'Autopostback' true for each quantity field. The quantity fields are added dynamically so I don't know how many there will be and I want to know is there a way to capture the changes without writing a onchange event for each button.

I.e. can I loop through the form and update the quantities on postback, my attempts so far have failed as I can't work out how to run the code on postback with a button triggering the event.

Yeah sure. Either rebuild the dynamically created controls and retrieve their text value or look at Request.Form.

I would appear that I could solve this problem by using the ontextchanged to fire a sub routine. But I can not see how I might add such an event to the TextBox control dynamically from the code behind page.

Any Ideas

Use AddHandler to add handles to dynamically creted controls
