combobox beforeselect

[seltzlab]

Hi all,
it seems that the beforeselect event of a combobox fires before the select event but the select event does not wait the beforeselect handler has returned.. it simply fire immediately after.
There's a way to fire the select event only after the beforeselect handler has finished?

Thanks a lot,
Antonio

Hello Antonio,

I've been having the same problem with comboboxes, and have not yet found a solution. It seem that the SQLiteStore ignores this, as far as I can tell, but it shouldn't as its just an extension of Ext.data.Store.

Anybody can comment on this?

Hi!
It's hard to understand.
Can you give some example code, please?

Ext.override(Ext.form.ComboBox,
    {
        onListSelectionChange: function(list, selectedRecords) {
            var me = this;
            // Only react to selection if it is not called from setValue, and if our list is
            // expanded (ignores changes to the selection model triggered elsewhere)
            if (!me.ignoreSelection && me.isExpanded) {
                var allowSelect = true;
                var lastSelectedRecord = me.picker.getSelectionModel().lastSelected;


                if (lastSelectedRecord != undefined)
                    allowSelect = me.fireEvent('beforeselect', me, lastSelectedRecord) !== false;
                    
                if(allowSelect)
                {
                    if (!me.multiSelect) {
                        Ext.defer(me.collapse, 1, me);
                    }
                    me.setValue(selectedRecords, false);
                    if (selectedRecords.length > 0) {
                        me.fireEvent('select', me, selectedRecords);
                    }
                    me.inputEl.focus();


                } else {
                    me.picker.getSelectionModel().deselect(lastSelectedRecord);
                }
            }
        }
 });
