try using following method
private void CheckState(bool p)
   {

   foreach (GridViewRow row in gdvdraftmails.Rows)
   {
   CheckBox chkcheck = (CheckBox)row.FindControl("chkcheck");
   chkcheck.Checked = p;
   }
   }

here is the solution for your code :
1. Generate CheckBox1_CheckedChanged event in ur code
2. Implement this code in above event
CheckBox chkbox = new CheckBox();
foreach (GridViewRow row in gvApplicable.Rows)
{
chkbox = (CheckBox)row.FindControl("Chk1");
if (chkbox.Checked == false)
{
chkbox.Checked = true;
}
else
{
chkbox.Checked = false;
}

}
