So I have Treeview that reads Channel Data from a remote Hierarchical DataSource:
So as above, tree nodes (child channels) are retrieved on an as needed bases, when a node is opened, this is donw by executing this URL: "/planner/channelnodes/forTree/1" (for example I expans the first node).
So this is where my issue starts, Id like to implement serverFitlering as well, how can I also execute a filter (ie. add the filter param to the URL) when a tree node is expanded and the read URL is executed? Is there a way to execute a read and filter together or to append the 'filter' param & value to the read URL during a 'requestStart' or 'parameterMap' or a read request?
Thanks and kind Regards,
