Due to the nature of my data I wanted to force the tree grid to dynamically load data when a node is expanded. So by default all my nodes would have a plus next to them then when you expand the node it queries my database and checks for sub items then loads them.
Is there a way to force a plus next to my nodes without loading in a fake child ?
Cheers

Yes, it possible. Please check tutorial here docs.dhtmlx.com/doku.php?id=dhtm … n_treegrid
But there is one limitation. It will not possible to open one or all nodes with API call, only with mouse click
Hi Olga,
I am using addRow to create my treegrid not xml or JSON. I understand that there is a child variable that i can set to 1 which does force the plus
addRow(new_id,text,ind,parent_id,img,child)
, however i can then not pick up the attempted expand with
mygrid.attachEvent("onOpenStart", function(nodeId,mode){
alert('change');
});
Any help would be great
Thanks
Nic
Try to use “onDynXLS” event:
grid.attachEvent(“onDynXLS”, function(start,count){
grid.addRow(…);
return false;
});
This event will be fired when you start to open node which children are not loaded yet.
