Hi
I will like to know if I have a selected row

This is my code

[code]
var oTable;
$(document).ready(function() {
oTable = $('#example').dataTable( {
"bProcessing": true,
"sAjaxSource": "tomacorrienteslist.jsp",
"bFilter": false,
"bSort": false,
"bInfo": true,
"bPaginate": false,

"aaSorting": [[ 4, "desc" ]],
"aoColumns": [
{ "mData": "codigo" },
{ "mData": "descripcion" },
{ "mData": "xbee_id" }
],
"sDom": 'T<"clear">lfrtip',
"oTableTools": {
"sRowSelect": "single",
"aButtons": [ ]
}
} );


} );

Look at:
http://www.datatables.net/extras/tabletools/api and you'll want fnGetSelected

Yes But I am getting this error
Uncaught TypeError: Cannot call method 'fnIsSelected' of null
[code]
var oTT = TableTools.fnGetInstance( 'example' );

if ( oTT.fnIsSelected( $('#example tbody tr:eq(0)')[0] ) ) {
alert( 'First row is selected' );
} else {
alert( 'First row is not selected' );
}
[/code]

Any idea why?

I have the answer.
If someone has the same issue I live the source code
[code]
var oTable = $('#example').dataTable( {
"bProcessing": true,
"sAjaxSource": "tomacorrienteslist.jsp",
"bFilter": false,
"bSort": false,
"bInfo": true,
"bPaginate": false,
"sDom": '<"clear">lfrTt',
"aaSorting": [[ 4, "desc" ]],
"aoColumns": [
{ "mData": "codigo" },
{ "mData": "descripcion" },
{ "mData": "xbee_id" }
],
"oTableTools": {
"sRowSelect": "single",
"aButtons": [ ]
}
} );

$( "#editar" )
.button()
.click(function() {
oTT = TableTools.fnGetInstance( 'example' );
var filas=oTT.fnGetSelectedData();
if(filas.length == 0){
alert( 'First row is not selected' );
}
else{
alert( 'First row is selected' );
$( "#editar_data" ).modal( 'show' );
}
