    Default Default Value in ComboBox

    Default Value in ComboBox


    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...

            triggerAction: 'all',
            selectOnFocus:false,
            forceSelection: true,
            value: 20,       ---------> Default Value will be 20

    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!
