Pure client-side treeview state persistance

[Jonathan]

Hi,

I am trying to persist a treeview's state purely using client side code
I am currently trying to use get_clientState & set_clientState and saveClientState & updateClientState, but with little success.

Currently all nodes are loaded via webservice (MVC) and use checkboxes

Do you have suggestions on the best way to accomplish this?

Thanks

Hello Jonathan,

I am not sure exactly what you mean by 'state', but you can always iterate over all nodes and check whether they are checked, expanded etc. and you can store this info with the approaching planning to use. Later you can use the same information to set the same states back to the nodes.

Kind regards,

Just to continue, currently new nodes are loaded on demand through a WebService. Upon clicking a button, information from this tree is used on the server side (through an ajaxrequest), but the new nodes aren't showing up, even with an updateClientState() call on client-side.

Any suggestions?

Hi Edward,

The experienced behavior is the expected one since you are using the WebService Load on Demand. Please refer to the following help topic for more information.
