Today I will show how to load information into a grid from an XML file, this is something very easy to do and useful when developing applications.
One of the most interesting components from ExtJS are the grids, which provide us the ability to display information in a simple and orderly way.
Many times it is necessary to create specific validations for our applications and are necessary to achieve the correct functionality, this tutorial explains how we can create “vtype’s” to validate our ExtJS forms.
The validations are very important when we’re saving the information the user entered, we should always validate the information we receive. In today’s tutorial we will see how to use the validations ExtJS provides.
Sometimes the information we use in our applications is grouped into categories, in these situations the linked combos will help us to maintain these connections in a simple way.
Today we will see how to send the information submitted in a form of Ext JS to the server in order to save it in a database or manipulate it in any way.
In today’s topic we will see how to fill out a form using Ajax to make a request to the server, we will request the information with an identifier we’ll send as a parameter.
Today we will talk about the DateField component. This component provides an “input” type formatted date from a calendar very well stylized. DateField in Ext JS is a very complete component since it offers many configuration options. In this tutorial we will discuss the most important settings.
Today we will talk about a very complete component: the ComboBox. We will see how to configure a Combo Box locally and remotely. I will describe some of the properties used in the configuration, we will create a template so our ComboBox will have a nice format and finally we will see the different variations that ExtJS offers for the ComboBox, for example the TimeField.
Among the many types of panels that ExtJS offers, we have the Ext.FormPanel component, a component that provides all the functionality of a common form in HTML but with methods and specific functions of ExtJS.
