    What is the way to delete all items from RadListView on client-side? I suppose I can use deleteItem() method but it requires an index so I need to get at least items count somehow.

    I also have tried to use get_clientDataKeyValue() method but it doesn't return what I expect (array of actual items).

    Hello Andrey,

    The RadListView does not serialize the data on the client and each call to deleteItem will initialize a request to the server.
    To implement the desired functionality, I recommend that you fire a custom DeleteAll command client-side and handle it server-side and delete all RadListView items.

    I hope this helps.

    Best wishes,
