How to combine confirm MessageBox with beforeselect event on treegrid?

[kramarskiy]

I'm facing a problem that i need to ask user for an action when he switches from node to node on treegrid, i'm using beforeselect event within controller and Ext.MessageBox.confirm, so after user pushes the button on messagebox i need to be able select the node he wanted to select or cancel the selection. My problem is that confirm message passes the node to be selected, i can't return false because beforeselect event function works behind the messagebox. Does anyone know how to make it working ?

                        var check = this.makeCheck();
                        var out = false; //or true - depends on question in alert
                        if(check){
                            Ext.MessageBox.confirm('Confirm', 'Are you sure you want to do that?',                      function(btn){

                                out = true;  //or false - depends on question in alert
                                
                            }, this);

                        return out;
}
                }

HI!

try this:-

 beforeselect: function(view, record,  index,  options) { 
    var check = this.makeCheck(); 
    if(check){
          Ext.MessageBox.confirm(
                   'Confirm'
                   , 'Are you sure you want to do that?'
                   , function (btn) {
                       if (btn == 'yes') {
                           // do what ever you want here...
                       }
                   }
               );
    }
}

suppose after pressing yes button i want to cancel selection, how can i do that? if i return false after i check yes button it doesn't work, treegrid revices nothing(that means that row can be selected) before user takes an action and press Yes button

why you need to cancel if it is already confirm by user in confirm box?

[kramarskiy]

ok, what if user presses No button?

[kramarskiy]

yes, but it doesn't work that way ... that is question!

you may return false if user clicks on NO button

[sword-it]

it should work, have you checked API Docs?

beforeselect( Ext.selection.RowModel this, Ext.data.Model record, Number index, Object eOpts )
Fired before a record is selected. If any listener returns false, the selection is cancelled.
