Solution 1

implement some javascript calculate the price and quantity. By firing the script on the quantity text box onBlur event you could then update the prices accordingly.

<input type="text" id="txtQuantity" onblur="calcualteValues()">

Thanks for the solution but there can be no of products ,so should I use the scrip in each text box???
Please elaborate the solution.

yes add the script to each product but pass the id of the textbox into the script:
<input type="text" id="txtQuantity1" önblur="calcualteValues(txtQuantity1.ClientId)"> or something similar.

Your javascript should then be function(idOfControl){};

5 for this because server-side handling of TextChanged is a terrible user experience and doing it with client-side script is the correct answer.

ed: even if you need some server-side information, you should do it with client script and AJAX

Thanks. things like this should always be done client side as you said. Takes too much pain to do it server side and is slower.
