how to pass javascript input type=text value back to code behind (vb.net)

Hi All,

i'm a newbie here, i have been struggling for some times on this. I have a gridview, and in rowdatabound, i will dynamically create a table with the required data and checkbox will be added dynamically too. for each checkbox, i have 2 hidden textbox keeping the id , cause i will retrieve the id base on the selected checkbox.

I was thinking of using javascript to retrieve the data, i could retrieve the data, but how do i pass the id back to code behind for further process?

Any help would be greatly appreciated.

Thank you
