| UX Component | User-defined Sub-themes to Style UX Component Controls | Many of the controls on a UX component allow you to specify a sub-theme. The sub-theme controls various aspects of a control's appearance and also behavior. For most of the controls there are several built-in sub-themes to chose from. For example, buttons have sub-themes that can make the button look like a 'back' or 'next' button. A powerful aspect of sub-themes is the fact that it is very easy for developers to create their own sub-themes to create highly customized appearances for controls on a UX. In this video we show how a custom sub-theme for a window can be created and used. Watch Video - Part 1 Watch Video - Part 2 Download Component |
| UX Component | Getting a Pointer to a Parent or Child Component So You Can Call Methods of the Parent or Child Component | The ability to re-use components and open a child component in a window, div, TabbedUI pane, Panel, or embed into a parent component is one of the most powerful aspects of the Alpha Anywhere architecture. When you open a component from a parent component, you will often want to get a pointer to the child component so you can manipulate it in your Javascript code in some way. For example, you might want some code in the parent component to read a control in the child, or set a value in the child. Similarly, you might want some code in the child component to read or set a control in its parent. The .getParentObject() and .getChildObject() methods are used to get pointer to an object's parent or child objects. In this video, we show how this is done.

| Grid Component | Putting the Search Part in a Pop-up Window | In this video we show how the Search part of a Grid component can be shown in a window. By default, the Search part is shown on the page directly above the Grid part, but by showing the Search Part on in a window, you can save space on the page.

| UX Component | Example App Showing How to Synchronize an Embedded UX Component when a Value in a Parent UX Component Changes | A common pattern when building mobile applications is to break the application into multiple sub-components and then embed child components into the parent component. Using this pattern, you break your application into manageable pieces. However, when you follow this pattern, it is often necessary to synchronize the embedded child component when a value in the parent component changes. In this video we show a sample application that shows customers in the sample Northwind database. An embedded UX component shows the orders for the selected customer. When the user selects a different customer, the embedded 'Orders' UX component is synchronized.

| UX and Grid Component | Handling Missing Images | When a UX or Grid component displays images, there is a possibility that an image referenced in an image tag is missing. A new onImageError client side event allows a developer to programmatically handle this situation and decide what image to display in place of the missing image. Watch Video |
| UX Component - List Control | Custom Layout - Setting a List Item Size to Fill the Screen - Understanding the 'Fill' Option for List item size and Custom Scrolling Options. | When you are working with a List control that uses a free-form layout for the List, you can set the height (and width in the case where the List is set to scroll horizontally) of each 'row' (i.e. 'item') in the List. In addition to setting an explicit size (say 200px) for an item height or width, you can also use the special 'fill' keyword to indicate that the item should fill the viewport. When you use the 'fill' option, it is often desirable to customize the way in which the List scrolls, so that it scrolls in discrete amounts (for example the size of the viewport) rather than scrolling continuously. By setting the item size to use the 'fill' keyword, and by customizing the List scrolling, it is possible to make a List behave much like a Panel Card in a Panel Navigator. In this video we show how these options are used. Watch Video - Part 1 Watch Video - Part 2 |
