I have an AJAX enabled application that uses the WebTree and works well. However, I am adding search capability that requires the use of javascript on the client to react to a row onclick event on a table. I wrote a javascript function to handle the click event and search my tree to get to the correct node. However, I want to force a partial postback to that the UltraWebTree_NodeClick event is fired. I would think that using .NeedPostBack = true; would work, but nothing seems to happen. Please see my code below.
function SetNode(cat1, cat2, cat3){ var tree = igtree_getTreeById("UltraWebTree1"); var nodes = tree.getNodes(); for (var i = 0; i < nodes.length; i++){ if (nodes.getDataKey() == cat1){ nodes = nodes.getChildNodes(); for (var x = 0; x < nodes.length; x++){ if (nodes[x].getDataKey() == cat2){ nodes = nodes[x].getChildNodes(); for (var y = 0; y < nodes.length; y++){ if (nodes.getDataKey() == cat3){ //Found IT! nodes.setSelected(true); //Force the post back! tree.NeedPostBack = true; }; }; }; }; }; }; }
Ideally the user would not see the postback - it would be exactly as if the user had clicked on the themselves.
Thanks,

Hi Rob,
I would use the WARP panel in this scenario. Place the Tree in a WARP panel, and use the Warp's .refresh client-side function to force a partial refresh.

I am trying to do a similar thing for part of my application, but shoehorning another panel in underneath the tree is going to be a significant effort. Is there any way to do a node.click(); or similar client function?
