HowTo suspend change event when drop to a node on treeview

[delagoutte]

Hello,

I have a drag and drop functionality between a unidbgrid and a unitreeview.

 

For do that i,'m using this code :

on unidbgrid

function beforeInit(sender, config)
{
    config.enableColumnMove = true;
    config.viewConfig = 
      {
        plugins: 
          {
            ptype: 'gridviewdragdrop',
            dragGroup: 'MainGridDrag',
            dropGroup: 'UserTreeDrop'
          }
                     
        }
}

on treeview :

function beforeInit(sender, config)
{
  config.viewConfig= 
  {
    plugins: 
      {
        ptype: 'gridviewdragdrop',
        dragGroup: 'UserTreeDrop',
        dropGroup: 'MainGridDrag',
        enableDrag: false
      },
    listeners: 
      {
       beforedrop: function(node, data, overModel, dropPos, opts) {
        this.droppedRecords = data.records;
        data.records = [];
        },
      drop: 
        function(node, data, overModel, dropPos, opts) 
          {
            var SelectRec = '';
            Ext.iterate(this.droppedRecords, 
              function(record) 
              {
                if (SelectRec == '') 
                {SelectRec += record.get('id')}
                else 
                {SelectRec += '-'+record.get('id')};        
              });
              
          ajaxRequest(sender, "_ddrop", ["GridSel=" + SelectRec , "TreeSel=" + overModel.get('id')]);
          this.droppedRecords = undefined;
      }
    }
  }
} 

the functionality must working like outlook, i have records on unidbgrid that i  affect on directory(treeview node) with drag and drop functionality.

After when i click on node that is doing a filter on grid for having the record affected to this directory

 

 

My problem is when i drop record on treeview the onchange event is fired before drop event.

How to suspend event onchange when i'm using drag and drop ?

 

i'm trying 

sender.getSelectionModel().suspendEvents(true); on beforedrop

and

ajaxRequest(sender, "_ddrop", ["GridSel=" + SelectRec , "TreeSel=" + overModel.get('id')]);           sender.getSelectionModel().resumeEvents(); on drop

but it don't work. Any Idea ?
