Default Value in ComboBox

[deepakmehta22]

Hi,
This is regarding the default value selection in Combo Box.
Problem : I have created new Combo Box and given the "Empty text" some default value which should be there while initial loading of Combo.But when i change the value of Combo to something else i lost my Default Value.For eg when combo loads the default value is 'Pick a Region ...' but when i changed to something else the default value is lost..

So how it can be retained.Any Idea ???

Here are my Setting::

new Ext.form.ComboBox({
fieldLabel:'Office Region',
name:'userRegion',
id:'settingsRegCombo',
store: getRegDS(),
valueField:'id',
displayField:'text',
typeAhead: true,
mode: 'local',
triggerAction: 'all',
emptyText:'Pick a Region ...',
selectOnFocus:true,
resizable:false,
forceSelection:true,
allowBlank:true,
blankText:"Pick a Region"

});

Thanks a lot for the help...

var combo = new Ext.form.ComboBox({
        store: ['10', '20', '30'],
        triggerAction: 'all',
        selectOnFocus:false,
        forceSelection: true,
        value: 20,       ---------> Default Value will be 20
        editable: false
    });

Awesome tip! I also learned that one can define the local store variables in-line. Too kewl! This helped me tremendously. I only added a hiddenName to send data to the database and have it automagically load the comboBox when the record is being edited.

Thank you!
