    Default Unanswered: Combo box - reset problem

    Unanswered: Combo box - reset problem


    Hi All,

    I want to achieve chained combo box . I mean 3 level combo boxes,

    Level 1 - Country

    Level 2 - State

    Level 3 - City.

    It works fine.


    But the problem is if user try to change the country name, the state and city combo box is not getting reset


    Code:
    var Country = new Ext.form.ComboBox(
        {
            name            : 'Country',
            editable        : false,
            id                : 'Country',
            fieldLabel        : 'Country '+mandatoryField,
            store            : CountryStore,
            bodyStyle        : 'padding:15px',
            loadmask        : false,
            displayField    : 'countryname',
            valueField        : 'countryid',
            allowBlank        : false,
            anchor            : '95%',
            typeAhead        : true,
            forceSelection    : true,
            queryMode        : 'local',
            triggerAction    : 'all',
            listeners         : 
            {  
                select: function(combo, record, index) 
                {
                    var val = Ext.getCmp('Country').getValue();
                    var record = Ext.getCmp('Country').findRecord(Ext.getCmp('Country').displayField, val); 
                    var ctry = record.get('countryid');
                    Ext.getCmp("State").getStore().removeAll();
                    Ext.getCmp("State").setValue('');
                    Ext.getCmp("City").getStore().removeAll();
                    Ext.getCmp("City").setValue('');
                } 
            }    
        });
        CountryStore.load();
        
        
        var State = new Ext.form.ComboBox(
        {
            name            :'State',
            id                :'State',
            fieldLabel        :'State'+mandatoryField,
            store            : StateStore,
            mode            : 'remote',
            displayField    : 'statename',
            valueField        : 'stateid',
            allowBlank        : false,
            editable           : false,
            anchor            :'95%',
            triggerAction    : 'all',
            typeAhead        : true,
            queryMode        : StoreQueryMode,
            forceSelection    : true,
            listeners    : 
            {
                select: function(combo, record, index) 
                {
                    var val = Ext.getCmp('Country').getValue();
                    var record = Ext.getCmp('Country').findRecord(Ext.getCmp('Country').displayField, val); 
                    var ctry = record.get('countryid');
                    
                    var val = Ext.getCmp('State').getValue();
                    var record = Ext.getCmp('State').findRecord(Ext.getCmp('State').displayField, val); 
                    var stat = record.get('stateid');
                    
                    Ext.getCmp("City").getStore().removeAll();
                    Ext.getCmp("City").setValue('');
    
                }
            }
        });
        StateStore.load();
        
    
        var City = new Ext.form.ComboBox(
        {
            name            : 'City',
            id                : 'City',
            fieldLabel        : 'City'+mandatoryField,
            store            : CityStore,
            loadmask        : true,
            mode            : 'remote',
            displayField    : 'cityname',
            valueField        : 'cityid',
            allowBlank        : false,
            typeAhead        : true,
            forceSelection    : true,
            queryMode        : 'local',
            anchor            : '95%',
            triggerAction    : 'all'
        });
        CityStore.load();

    Hi renganathan,

    I read your post and I think you are getting this issue because of problem with your store in Country combobox. I can't see your store and model configuration, but there is a problem with:

    valueField: 'countryid'

    If this configuration is wrong, event 'select' or 'change' will not work for you, I think event 'select' will fire only once.

    Please check your model for Country store and I think this should helps. And by the way, you can simply clear comoboxes using this:

    Ext.getCmp("City").reset();
    Ext.getCmp("State").reset();

    Please, be careful with removeAll() method, if your store will fire sync with database, it will remove your all data.

    Thanks.
