extjs 4 combobox , How to disabled tab and enter key

Question

I am using extjs 4.0.7. I want to disabled tab and Enter key event when user using Combobox. I have tried to use keyUp and KeyDown event. But I didn't get any alert for it.

Here is my code:

{
  xtype: 'combo',
  store: ds,
  id:'UserBO_SelectComponentId',
  displayField: 'displayName',
  valueField: 'userId',
  typeAhead: false,
  hideLabel: true,
  disabled: false,
  hideTrigger:true,
  multiSelect:true,
  delimiter: ";",
  anchor: '100%',
  triggerAction: 'all',
  listeners: {
     change: function( comboField, newValue, oldValue, eOpts ){
       selectUserCallBack2(newValue,'UserBO_SelectComponentId',comboField,oldValue);
     },
     select:function(comboField,oldValue){
        testRec(comboField,oldValue)
     },
     keypress:function(comboField,e){
        disabledKeysOnKeyup(comboField,e)
     }
  },
  listConfig: {
     loadingText: 'Searching...',
     enableKeyEvents: true,
     emptyText: 'No matching posts found.'
  }, 
  pageSize: 10 
}

Can anyone please suggest what is the problem here?

The keyup, keydown and keypressed events only fire if enableKeyEvents is set to true. Default this is set to false, so you need to add enableKeyEvents:true to the combobox config. And then do special treatment for enter and tab key.
