    I got the same problem with RadGrid - and it got solved here with a sample.
    The thing is - I want only one Element expanded at a time.

    So the solution (for grid) was to handle the item command.
    This command is not fireing for expand / collapse with Grid-Ajax.

    So the soltuion no longer works.
    Is there another way to achive the same task?

    Sorry for that - I got it running by setting


    This works good for the current solution.

    I guess there would be a method to make this work also with Client as load mode - but it is litte data I transfer so it does not matter.

    As Manfred states changing the load method to-

    HierarchyLoadMode ="ServerOnDemand"

    works, but it seems a shame to return to the server to fire this action. Is there a solution where this can be called from the client with HierarchyLoadMode ="Client" and a client side function action the same Single Expand?

    Hi Marcus,

    The setup relies on checking the command name, and collapsing the previously expanded item/level. This is why it needs to have a server load mode.
    If you would like to handle this logic on the client, you can use the collapse method:

    I hope this information helps.
