If any of TextBox is not equal to 0, then multiply the value with 7. How can I do it? If users enter values like 3 or 4 in few text boxes, then those values should be multiplied with 7 and other Text Boxes with default value 0 should be ignored. How to achieve this in a simple way.
I created like this, but not satisfied since the block size will increase when no. of products get increased. So, Can the method you suggested solve that?
You need to begin learning about lists for storing all your product data, then how to work with the lists to present your products without having to create display components for each products.
You can use a listview for this, and combine its functionality with a notifier for user interaction.
