If you will execute mygrid.getRowsNum() method after first portion of rows was loaded it will return total number of records:

mygrid.loadXML("dynload.php",function(){
  alert(mygrid.getRowsNum());
 });

thanks, it works but if I do the code below it returning me 0:

mygrid.loadXML("dynload.php");

alert(mygrid.getRowsNum());

I need to put the number of row in a variable... It does not work if I do

mygrid.loadXML("dynload.php");

var nNumberOfRow = 0;

nNumberOfRow=mygrid.getRowsNum();

alert(nNumberOfRow);   -> return 0

Do you have any idea?

This code returns 0 because of by the time of executing alert(mygrid.getRowsNum()); any row was loaded to the grid. The only way to detect when first portion of rows was loaded is to use 2nd paramether of loadXML method. 

Ok, so I can not use it outside the function loadXML in 2nd parameters? Because this code below does not work too:

var intNumberOfRow = 0;

mygrid.loadXML("dynload.php",function(){
  intNumberOfRow = mygrid.getRowsNum();
 });

alert(intNumberOfRow); -> return 0
