    Default Answered: Adding & Removing Select Event Listener From Grid

    Answered: Adding & Removing Select Event Listener From Grid


    Good day all!!!

    I have a girdpanel to which I'm a select listener function to from my controller. See code below:

    Code:
    init: function()
    {
    this.control(
    {
    'registrationWindow gridpanel[name=Member]':
    {
    select: this.onMemberSelect
    },
    });
    },
    
    onMemberSelect: function(grid, record, index, eOpts)
    {
    console.log('firing member select');
    },
    Now what I'm trying to do is add a new row


    remove the select listener

    select the row (should not fire select event because it has been remove)

    add the select listener



    This is my code, see below:

    Code:
    onAddMember: function(button, e)
    {
    this.getMemberStore().removeAll(false);
    this.getMemberStore().suspendAutoSync();
    this.getMemberStore().insert(0, this.getMemberModel().create());
    this.getMemberStore().resumeAutoSync();
    
    this.getMemberSearchGrid().getSelectionModel().un('select', this.onMemberSelect, this); //select listener is not being remove and console still outputs 'firing member select'
    this.getMemberSearchGrid().getSelectionModel().select(0);
    this.getMemberSearchGrid().getSelectionModel().on('select', this.onMemberSelect, this);
    
    this.showMemberEditWindow(this.getMemberSearchGrid().getSelectionModel().getSelection()[0]);
    },
    Any help is greatly appreciated

  2. You could just call suspendEvents/resumeEvents.

    Thanx...

    That worked great:

    Code:
    this.getMemberDependantGrid().getSelectionModel().suspendEvents(false);
    this.getMemberDependantGrid().getSelectionModel().select(0);
    this.getMemberDependantGrid().getSelectionModel().resumeEvents(false);

    Just out of curiosity; how would I be able to acheive the same thing using removeListener and addListener.

    The code you have looked ok. I know that un is REALLY picky about getting the exact same params as the on. It may be that the control does something different like wrapping the callback so that it doesn't match the function you are passing in. I'd have to check the code to be sure.
