Is possible get the selected checkbox in the grid and send the list of the years selected in a URL?
for example, if I select only the year 1995 and 1996, send a url with this values:
filter_years.cfm?years=1995,1996
In this case I have a Iframe and I have a routine when it received the values in a url, update the page with information of the years 1995 an 1996 only.
But I don´t know, how to do this. 
Is possible send in a url the years selected, when I press the checkbox of any years?
for example:
if the year 1995 and 1996 are selected and then I click the checkbox 1996, send in a url
filter_years.cfm?years=1995
if i select again the 1996, send in a url:
filter_years.cfm?years=1995,1996
In my case, I have a xml next:
<?xml version='1.0' encoding='ISO-8859-15'?>
<rows>
<head>
<column type='tree' width='160'>Year</column>
<column type='ch' width='60'>apply</column>
<afterInit>
<call command='setEditable'><param>true</param></call>
<call command='setColSorting'><param>int,int</param></call>
<call command='setColAlign'><param>left,center</param></call>
</afterInit>
</head>
<row id='1995'>
<cell>1995</cell>
<cell>1</cell>
</row>
<row id='1996'>
<cell>1996</cell>
<cell>1</cell>
</row>
<row id='1997'>
<cell>1997</cell>
<cell>1</cell>
</row>
</rows>
And my html is this:
<script>
mygrid = new dhtmlXGridObject('gridbox');
mygrid.selMultiRows = true;
mygrid.imgURL = "../includes/codebase/imgs/";
mygrid.setColumnMinWidth(50, 0);
mygrid.init();
mygrid.setSkin("dhx_skyblue");
mygrid.enableAlterCss("even", "uneven");
mygrid.loadXML("../xml/series/years.xml");
</script>
