How can I display combobox text after form load?

[yumusakg]

I can post the value of remote combobox with hiddenName. I couldn't accomplish showing the text of combobox after form load. This is a remote combo. So the store is not loaded after form load. So the combo only shows the value field...

config for combobox

Ext.ns('portal', 'portal.common');

portal.common.store_combo_company = new Ext.data.JsonStore({
    root: 'data',
    url: '../common/presentation/commondata.aspx',
    baseParams: {
        cmd: 'combo_company'
    },
    fields: [{
        name: 'ParamID',
        type: 'int'
    },
    {
        name: 'ParamDescription',
        type: 'string'
}]
    });

    portal.common.ComboCompany = Ext.extend(Ext.form.ComboBox, {
        constructor: function(config) {
            config = Ext.apply({
                store: portal.common.store_combo_company,
                valueField: 'ParamID',
                displayField: 'ParamDescription',
                fieldLabel: 'Firma',
                mode: 'remote',
                typeAhead: false,
                triggerAction: 'query',
                minChars: 2
            }, config);

            portal.common.ComboCompany.superclass.constructor.call(this, config);
        }
    });

    Ext.reg('combocompany', portal.common.ComboCompany);

apart from form's config

{
            id: 'form_contract',
            url: 'prcdata.aspx',
            xtype: 'form',
            baseCls: 'x-plain',
            labelWidth: 120,
            bodyStyle: 'padding:10px',
            defaults: { anchor: '100%', xtype: 'textfield' },
            items: [{
                fieldLabel: 'contractId',
                name: 'contractId',
                xtype: 'hidden'
            }, {
                id: 'prc_firma',
                xtype: 'combocompany',
                emptyText: 'Seçiniz',
                hiddenName: 'Firma'
            }]
}

If the store hasn't finished loading when you set a value to the combo then you will need to reset the value once the store has finished loading.

the combo retrieves 5000 rows. so i don't want to load these rows in form load... what i wanted to make is displaying combo value and text without loading combo store...

You could use setRawValue to simply display the value you want.

I usally use a combination of setValue & setRawValue. So the combobox IS aware of the to-be-used-value and correctly transmits the value but without loading the store...

thank you @fschaeffer,

setRawValue worked very well.

But it is extra code to implement this common requirement.. I think this must be functionality of combo component. An additional config item like loadValue which will bind the action.result.data.<data_item> to combobox RawValue could be easily implemented.. so we didn't have to write extra code..
