shift select records in gridview asp.net - asp.net

Question

hey guys,
i have a gridview which displays 10records per page, now i want to implement shift+click option in my gridview, when user clicks on the first row and press shift key and click on the 5th row, all the rows between 1 and 5(1 and 5 inclusive) should be selected...
can anyone suggest how should i do this in javascript.

I take it back, I found a shift+click multiple select solution for a gridview. All credit goes to mdv over at the asp forums.
var _sPreviousRow = null;
function wsCheckRange(p_oGridView, p_oControl, e) {
var l_sCheckID = p_oControl.id;
var l_aCheckIDParts = l_sCheckID.split(p_oGridView.id);
var l_sCurrentRow = l_aCheckIDParts[1].split('_')[1].substring(3);
var l_oEvent = (window.event) ? event : e;
if (l_oEvent.shiftKey) {
if (_sPreviousRow != null && _sPreviousRow != l_sCurrentRow) {
var l_iFirst = 0, l_iLast = 0;
if (parseInt(_sPreviousRow,10) > parseInt(l_sCurrentRow,10)) {
l_iFirst = parseInt(l_sCurrentRow,10);
l_iLast = parseInt(_sPreviousRow,10);
}
else {
l_iFirst = parseInt(_sPreviousRow,10);
l_iLast = parseInt(l_sCurrentRow,10);
}
for (var i = l_iFirst; i < l_iLast; i++) {
var l_sLastRow = (i <= 9 ? '0' + i : i);
var l_sCtrlNew = l_sCheckID.replace('ctl' + l_sCurrentRow, 'ctl' + l_sLastRow);
var l_oCtrlNew = $get(l_sCtrlNew);
if (l_oCtrlNew) {
l_oCtrlNew.checked = p_oControl.checked;
}
}
}
_sPreviousRow = null;
}
else {
_sPreviousRow = l_sCurrentRow;
}
}
