    Hi,

     We need to programatically de-select a particular node in the ListView control. Listview has option - selectable: "multiple". We don't want to use clearSelection() as it will remove selection for all the nodes.

     Please let me know how we can achieve this.

    Thanks a lot.

    Hello Abhishek,


    In the current case you should use the select() method and select all required nodes without the one that should be deselected.

    Let me know if this was the information that you were looking for.

    Hi Dimiter,

     I tried your suggestion but could not achieve the item de-selection.
    This is the code I tried - 

    var remainingElementsToSelect = listView.select().not(itemToDeSelect);
    listView.select(remainingElementsToSelect);

    But still the 'itemToDeSelect' remains selected. 

    Thanks in advance.

    Hi Abhishek,


    Please excuse me for the inconvenience. I missed the fact that the select() method does not override the selection, but only adds to the existing one. I would suggest to clear the current selection, before applying the new one.
    E.g.
    var remainingElementsToSelect = listView.select().not(itemToDeSelect);
    listView.clearSelection();
    listView.select(remainingElementsToSelect);
