deselectRow(index) & getSelectionModel() index

[iBeb]

Hi there,

I'm experiencing a issue with getSelectionModel() and deselectRow().
I have a grid with a RowSelectionModel. There's one button to delete selected rows.
But before to delete the row, I have to check is one field in record.data is not equal to a certain value. Regarding this, I allow or not to delete the row, and deselect the row if not allowed.

    ,delRoom:function(p){
        p.getSelectionModel().each(function(item,index){
            if(item.data.parent_id==1||item.data.r_room_id==1){
                Ext.ux.Toast.msg(__('shared.popup.avertissement'),__('travel.popup.roomError'));
                p.getSelectionModel().deselectRow(index);
            }
        },this);
        return true;
    } 

The thing is getSelectionModel().each() returns the index of the row inside the selection, and to deselect a row you need the index of the row inside the grid

So as you can see, my function doesn't work, because I don't use the good index to deselect a row.
I don't know how to make the two indexes match.
Which method could I use from Ext.grid.GridPanel or Ext.grid.RowSelectionModel to make it work?

Thanx in advance,

You can define the row index from store. In this case it will look like:

 
p.getSelectionModel().deselectRow(p.getStore().indexOf(item));
