    Default Unanswered: setValue of a combobox with valueField

    Unanswered: setValue of a combobox with valueField


    This is my model for my combo

    Code:
    Ext.define('ExtJS.myApp.ComboModel', {
        extend: 'Ext.data.Model',
        alias: 'widget.combomodel',
        fields: [
            { name: 'ID', type: 'int' },
            { name: 'title', type: 'string' }
         ]
    });
    This is comboStore
    Code:
    this.comboStore = Ext.create('Ext.data.Store', {
                model: 'ExtJS.myApp.ComboModel',
                autoLoad: true,
                scope: this,
                proxy: {
                    type: 'ajax',
                    scope: this,
                    url: 'myApp/GetRecords',
                    reader: {
                        type: 'json',
                        root: 'data'
                    }
                }
            });
    Code:
    this.myComboBox = Ext.create('Ext.form.ComboBox', {
                store: this.comboStore,
                queryMode: 'local',
                displayField: 'title',
                valueField: 'ID'
            });
    This is the json object I get for my store:
    Code:
    {"ID":"111","title":"Ext Page 1"}
    now when I try to set the value of the combobox like this.
    Code:
    this.myComboBox.setValue('111');
    the combobox shows "111" instead of "Ext Page 1"

    What would I have to do so that the combobox displays displayField while setting valueField

    Are you setting the value *before* the store loads? this problem is an indication that you probably are.

    Why don't you use this.myComboBox.select('111') function of combo.

    Girish... thanks for your answer... I tried using select. It show up as '111' on the combobox. I actually want to show 'Ext Page 1'. And then when I try to save the value of the combobox. I want to save '111'. but either doing getRawValue or getValue gives me the displayField.

    Hi Jay... I tried setting the value after loading the store too, but get the same result. However, when I select a different item from the dropdown, I get the id numbers. It's not giving the right value only when I am trying to set a default value.
