Javascript using window.location seems to lose state

Not sure what forum so let me know if I'm in the wrong place.
I have a main window with a ajax grid that has a column of links that uses javascript and window.location to go to another page to show check stub information. When I use the backbutton on the browser everything persists on main window. Ok so far.
If I navigate to the window with the show check stub information, there is a 'Print' button that again thru javascripts prints the grid with the check info on it. (Code I got of the internet with some minor changes I made).view plaincopy to clipboardprint?function Print() { var curVisible = true; var grid_obj = document.getElementById('<%= grdVoucherDetail.ClientID %>'); for (var i = 1; i < grid_obj.rows.length-1; i++) { grid_obj.rows[i].cells[8].style.display = curVisible ? "none" : "inline"; grid_obj.rows[i].cells[9].style.display = curVisible ? "none" : "inline"; } if (grid_obj != null) { var new_window = window.open('print.html'); //print.html is just a dummy page with no content in it. new_window.document.write(grid_obj.outerHTML); new_window.document.close(); new_window.focus(); new_window.print(); new_window.close(); } curVisible = false; for (var i = 1; i < grid_obj.rows.length-1; i++) { grid_obj.rows[i].cells[8].style.display = curVisible ? "none" : "inline"; grid_obj.rows[i].cells[9].style.display = curVisible ? "none" : "inline"; } } function Print() {
var curVisible = true;
var grid_obj = document.getElementById('<%= grdVoucherDetail.ClientID %>');
for (var i = 1; i < grid_obj.rows.length-1; i++) {
grid_obj.rows[i].cells[8].style.display = curVisible ? "none" : "inline";
grid_obj.rows[i].cells[9].style.display = curVisible ? "none" : "inline";
}
if (grid_obj != null)
{
var new_window = window.open('print.html'); //print.html is just a dummy page with no content in it.
new_window.document.write(grid_obj.outerHTML);
new_window.document.close();
new_window.focus();
new_window.print();
new_window.close();
}
curVisible = false;
for (var i = 1; i < grid_obj.rows.length-1; i++) {
grid_obj.rows[i].cells[8].style.display = curVisible ? "none" : "inline";
grid_obj.rows[i].cells[9].style.display = curVisible ? "none" : "inline";
}
}

Now after the print and closing that popup I click the backbutton again and things don't seem to persist.
I did notice that the pageload of the main window (one I'm going back to) gets triggered after the printing of the grid where if I don't click the print button and go back the pageload does not get triggered.
Any ideas would be appreciated. I have searched and searched for an answer and am getting nowhere. When this happens I usually feel that I've done something stupid. Oh well
Thanks for any help that you can give me
