You can use a stringbuilder object to iterate through the rows of the checkbox and store the value. see this tutorial

On button click on which you want to save the values in the database.
Loop through earch row of the gridview.
Find the checkbox in that row
Check if it is checked or not

foreach (GridViewRow row in GridView1.Rows)
{
   if (((CheckBox)row.FindControl("CheckBoxUpdate")).Checked)
   {
       //insert here
   }            
}

Here is a good link for the same
