Unfortunately treeGrid hasn't appropriate method which can allow you to disable node images for the particular row. Bu if you know ids of the parent nodes, you can disable it's images via DOM. For example following code will hide item images for all rows which has children:

mygrid.loadXML("test_list.xml",function(){
                mygrid.forEachRow(function(id){
                if (mygrid.hasChildren(id)){
                    var cell=mygrid.cellById(id,0).cell.firstChild.childNodes[1].style.display="none";
                }
            })
});

Hi,

I am not creating the rows with xml. I have a dto object that is passed to the client side with asp.net ajax. I am creating the rows using addRow function.

You should execute code bellow only after grid was fully loaded. You can use "onXLE" event. 

mygrid.attachEvent("onXLE",function(){
  mygrid.forEachRow(function(id){
  if (mygrid.hasChildren(id)){
  var cell=mygrid.cellById(id,0).cell.firstChild.childNodes[1].style.display="none";
  }
  })
});

>>I am creating the rows using addRow function.

After rows was added to the treeGrid you can catch "onRowAdded" event which containg information about row id which was added:

mygrid.attachEvent("onRowAdded",function(id){

mygrid.cellById(id,0).cell.firstChild.childNodes[1].style.display="none";

}
