I suggest using javascript for this task (to prevent postback for each click)

give all your checkboxes an data-rowId attribute and each row the same id.
give all your textboxes a class (or other attribute) to know which ones to calculate.

Then add an event on all your checkboxes.

JavaScript

$('input[type="checkbox"]').on('click', function(){
   var rowId = $(this).attr('data-rowId');

   var sum = 0;
   $('#'+rowId+' input.calculateMe').each(function(){   
      var currentTextbox = $(this);
      var val = parseFloat(currentTextbox.val());
      sum += val;
   });

   $('#txtSumEveryting').val(sum);
});

hi,

you can do it in gridview itemdatabound event where you can find id of that record on checkbox click. and there you will have values for calculations and store in where you want.
