Use Required field validators. In fact it reduces the loading time and its need very samll validating time when compared to validate it in the code behind.

When all required fields satisfied execute your code in the submit button click event

To use required field validator refer this

if you want to do a validation in one go of foreach then you need repeater or gridview control or datagrid or if you have all textbox straight i would suggest you to do a one by one
