Hi,
I am facing a problem. I have inserted some data into a listview control.
The displaying data size is 3 records per page and the listview control has more than 5 records which are bound to a datatable.
But, when I try to get data from listview control using javascript then only 1st 3records are getting but not all records.
So how to get all records of the control, can you help me pls.
If any mistake forgive me.

Thanks in advance

What I have tried:

var lv = window.document.getElementById('tConsignment')

for (var i = 2; i < lv.rows.length - 1; i++)
     {
         //get the reference of 1st column that is Srlno index 0
         if (lv.rows[i].cells[0].textContent != "")
         {
             node = xmlDoc.createElement("Item");
             //get the reference of 1st column that is Srlno index 0
             var AttributeNode = xmlDoc.createAttribute("Srlno");
             AttributeNode.nodeValue = lv.rows[i].cells[0].textContent;
             node.setAttributeNode(AttributeNode);}
}
