[Solved] OnClientNodeClicking/ed and MultiSelect

[Peter Zolja]

Hi,

Since one of the trees was generating too much ViewState I decided to disable it and work around it using JavaScript. I need to be able to keep track of which nodes are selected. As soon as a node is selected I notify the server via AJAX.

Here's my problem:
1) If I use OnNodeClicked, the event fires only for the first click. It does not fire for subsequent selections (i.e. when I hold down Ctrl to select other nodes).
2) If I use OnNodeClicking and call get_selectedNodes() I only get back the old nodes and not the currently selected node. I assume because the event fires before the node is actually marked as selected.

So, how can I work around this?

Thanks,
Peter.

Hello Peter Zolja,

You can use the eventArgs.get_node() function to get a reference to the Node that is about to be selected (the rest of the selected Nodes you can obtain by calling the get_selectedNodes() of the TreeView).

All the best,

Thanks Simon, didn't think about doing it that way. Another way that seems to work is to use OnNodeClicking and launch a timer that does the processing. By the time the timer (I set it to 50ms) is launched all the nodes are properly selected and I can query the tree for selected nodes.
