Select rows limits?

Is there a way to select maximum number of rows per table instead of doing as many as you want? Using this http://www.datatables.net/release-datatables/examples/api/select_row.html

There isn't a built in way of doing it, but you could add a bit of logic to the selection event handler which would not select the row clicked on if there are a certain number already selected.

@allan - Thanks for your response. This is a what I came up with. So far it is working great :)

[code]

/* Add/remove class to a row when clicked on */
$('.dataGrid tbody tr').bind('click', function() {
var $_this, $_table, $_selected, i, thisRow, thisClass, tableRows = $(".dataGrid tbody tr"), trLen;
trLen = tableRows.length;
// Get the row that's just been clicked
$_this = $(this);
// Get its parent table
$_table = $_this.parents('table').first();
// Get all of the rows within it that have been selected
$_selected = $_table.find('tr.row_selected');
// If the row is already selected
if ($_this.is('.' + ROW_SELECTED_CLASS)) {
// Remove the selection
$_this.removeClass(ROW_SELECTED_CLASS);
// Remove class disabled class
$(".dataGrid tbody tr").removeClass('disabled');
} else {
// If it is not already selected
// If the number of already selected rows is less than the max
if ($_selected.length < MAX_ROWS) {
// Add the selection
$_this.addClass(ROW_SELECTED_CLASS);
}
//Add disabled class when max selected
if($_selected.length === MAX_ROWS - 1) {
