  Hello Faisal,
  
  You can access the attribute value either from client side or server side.
  Here is a sample code.
  
  server side.
  

  protected void Button1_Click(object sender, EventArgs e)

     {

         RadTreeNode node = RadTreeView1.FindNodeByText("a");

         Response.Write(node.Attributes["CompanyNode"]);

     }

  
  ClientSide:
  

  function getAttribute()

    {

      treeView = $find("<%= RadTreeView1.ClientID %>");

      var node=   treeView.findNodeByText("a")

      var value= node.get_attributes().getAttribute("CompanyNode");

      alert(value);

     }

  
  Thanks,
  Shinu.

  yes i know this way to access like node.Attributes["CompanyNode"]);

but i need the scenario like. i clicked on a node and i have that value. clickednode.value. in this case how 
i can access its attribute where i dont know its attribute name node.Attributes[ attribute name????]);

With Regards,

  Hello Faisal,
  
  You can get the attribute name by the property _key.
  
  javascript:
  

  for (var i = 0; i < node.get_attributes()._keys.length; i++)

              alert(node.get_attributes()._keys[i]);//returns the attribute name.

  
  Thanks,
  Shinu.
