How do you update checkbox while clicking on a button and then refresh the datalist.. here Im using a column as Isfavourite with datatype as int and with values as 0 and 1. so certain items will have values 0 and others will have 1.. now initially when I display the datatlist in the webpage it will have all items which has the value 1. now when i click on the checkbox the clicked checkbox will be updated with the value of 0 and that particular row should disappear from the list on a button click .. can anyone help me with the code or any link..
eg:items,price and is favourite are my 3 columns

Items  Price  Isfavourite
  a      1        1 
  b      4        1
  c      5        0
  d      6        1

Now I will select all rows where IsFavourite is 1

Items  Price  Isfavourite
  a      1        1 
  b      4        1
  d      6        1

now when I click on a check box say adjacent to a and then click on the submit button the new datalist to be displayed should be like this

Items  Price  Isfavourite
   b      4        1
  d      6        1

Hope you have understood my point
