I am using a treeview with ClientSideOnItemClick="treeview_itemclick_handler". The code for that function is:
function treeview_itemclick_handler(e, eventInfo) {
if (!window.confirm("Are you sure?")) {
return false;
}
}
When I click on a treeview node, the alert comes up fine, and clicking 'Cancel' does stop the postback, but the node I click on does get the "selected" style, so it appears that the selected node has been changed. How can I stop this from happening, so that if the user clicks 'Cancel' the selected node is not changed?
Thanks,
Bobby

Hi Bobby,
Try use ClientSideOnItemMouseDown instead of ClientSideOnItemClick. An item is selected on mouse down, not on mouse click.
Thanks

Ok-- I've switched to ClientSideOnItemMouseDown, and now the "click" server event is being raised even before I can address the alert, and the node "drag" begins even if I click "Cancel"-- I'll keep working with it to find the right combination and let you know if I absolutely can't resolve it myself-- thanks for the help!

Ok-- I think I know how to handle it but I need to know the selected node client-side.
How can I get the selected node of a treeview client-side?
My plan is to (1) store the selected node in a local js var
(2) if the item click is cancelled, set the selected node back to the original selected node. Like:
var TreeView1 = eo_GetObject("<%= TreeView1.ClientID %>");
var selectedNode = ????? HOW DO I GET THIS?
function treeview_itemclick_handler(e, eventInfo)
{
if (!window.confirm("Are you sure?")) {
eo_GetObject("<%= TreeView1.ClientID %>").SetSelectedNode(selectedNode);
return false;
}
}

Cool! Glad you worked out! I believe the latest build (from our download page) supports getSelectedNode on client side TreeView object.

Got the new version (2.16) and now I am getting an error that the treeview object doesn't support the method setSelectedNode(node, false). Has this method been removed? I can verify that my local var TreeView1 does correctly point to the tree, and that the node var does point to the correct node.
Also, with the new version I am now getting license errors. Do I need to download a new license file or put it somewhere different with this new version?
Thanks,
Bobby

Hi Boddy,
Try selectNode. That function should be there.
Thanks
