Hi Simon - thanks for this -
I created a little function as per the instructions your referred to which is
var node = eventArgs.get_node();
var myDiv = document.getElementById("myDiv");
"Category: " + node.get_text() + " - " + node.get_category();
The .get_text works find and I get the text of the node I am hovering over but the .get_category gives me null all the time. Now, my tree is being fed by a sql server table - would that affect anything. Also, if I am able to get the value of the CategoryID this way, could you tell me where I should call it from - I'm just feeling my way around here - would it be on the RadGrid1_RowDrop event - if so how?
Thanks for your patience.
