    Hello,

    I would to show sum of two numberfields value into another numberfield but i don't know how to do.

    Here is my numberfield declaration :
    HTML Code:
    {
        xtype: 'numberfield',
        labelWidth: 250,
        name: 'number1',
        fieldLabel: 'Enter first number',
        minValue: 1
    },
    {
        xtype: 'numberfield',
        labelWidth: 250,
        name: 'number2',
        fieldLabel: 'Enter Second number ',
        minValue: 1
    },
    {
        xtype: 'numberfield',
        labelWidth: 250,
        name: 'result',
        fieldLabel: 'Result  ',
        minValue: 1
    },
    When user put number1 and number2 values, i want to assign automatically the sum result at third numberfield with my controller.

    Default

    Listen to change event on either field and call setValue on the third field in the event handler for each field.
