Design Dialog

Overview

Dragging and dropping a dialog creates a view containing the dialog. The view can be selected from the Page Structure or from the tabs given at the bottom. The display of the dialog box at runtime is usually associated with the onClick event of a Button widget. You can also trigger the dialog by calling methods from JavaScript.

Design Dialog gives a Form for obtaining additional information from the user, like the name. It is a composite widget with Labels and Text widgets. It comes with two buttons **Cancel **and Save.

Script Access

Dialog widget in your project can be accessed by associating the open and close properties of the dialog with an event of any other widget. The dialog can be accessed through scripting by adding DialogService to the page controller and adding the code for open and close as shown below, here we are displaying an alert dialog on click of a button: Click event of the button should trigger the following JavaScript code:

Page.button3Click = function($event, widget) {
     Page.Widgets.designdialog1.open();
 }

For hiding dialog:

/* function called on button1 click */
        Page.button1Click = function($event, widget) {
            Page.Widgets.designdialog1.close();
        };
