jQuery/JS Common - utils - ui - dialog - Methods
This section describes the methods exposed by the DevExpress.ui.dialog object.
alert(message, title)
Creates an alert dialog message containing a single "OK" button.
A Promise that is resolved with the dialog result data when the dialog is closed. It is a native Promise or a jQuery.Promise when you use jQuery.
The "alert" dialog is a notification dialog consisting of an alert message and a single button that closes the dialog.
Pay attention to the recommendations given for using modality in the Modal Contexts article. In certain scenarios it may be better to display a modal view instead.
confirm(message, title)
Creates a confirm dialog that contains "Yes" and "No" buttons.
A Promise that is resolved with a Boolean value specifying whether the user has clicked the "Yes" or "No" button when the dialog is closed. It is a native Promise or a jQuery.Promise when you use jQuery.
The "confirm" dialog enables you to confirm the operation you are going to complete. The dialog shows a message and suggests two choices: "Yes" and "No". Note that the confirm dialog returns a Deferred object that contains a Boolean value indicating whether a user confirmed or canceled the action. Use the following code to obtain dialog results.
var showConfirm = function () {
    var result = DevExpress.ui.dialog.confirm("Are you sure?", "Confirm changes");
    result.done(function (dialogResult) {
        alert(dialogResult ? "Confirmed" : "Canceled");
    });
};Pay attention to the recommendations given for using modality in the Modal Contexts article. In certain scenarios it may be better to display a modal view instead.
custom(options)
Creates a custom dialog.
An object representing the dialog.
To create a custom dialog (with a custom set of buttons), call the DevExpress.ui.dialog.custom(dialogOptions) method. Specify configuration options for the dialog using the fields of the object passed as a parameter.
Unlike the alert and confirm methods, the custom method does not display the dialog. Call the show() method of the created dialog instance to show the dialog.
var showDialog = function () {
    var myDialog = new DevExpress.ui.dialog.custom(dialogOptions);
    myDialog.show();
};The show() method returns a Promise that is resolved with the dialog result. Use the following code to obtain the dialog result.
var myDialog = DevExpress.ui.dialog.custom(dialogOptions);
myDialog.show().done(function(dialogResult){
    alert(dialogResult);
});Use the hide() method to close the dialog before any button is clicked. The following code displays a dialog, and hides it if no button is clicked within 5 seconds.
var showDialog = function () {
    var myDialog = DevExpress.ui.dialog.custom({
        title: "Self hiding dialog",
        message: "This dialog will close after 5 seconds",
        buttons: [{ text: "Close now" }]
    });
    myDialog.show();
    setTimeout(function () { myDialog.hide(); }, 5000);
}Pay attention to the recommendations given for using modality in the Modal Contexts article. In certain scenarios it may be better to display a modal view instead.
