CRM 2013 introduces a couple of client side dialog methods under the Xrm.Utility library. The goal is to remove the use of window.open and window.confirm and replaces them with alertDialog and confirmDialog and to support these alert messages in CRM for Tablets. Also, the key difference is that these methods will not block code until a user closes them. However, they contain a callback function parameter to indicate what code should be executed depending on the user’s response.
The Xrm.Utility.alertDialog(message,onCloseCallback) method displays a dialog box that contains a message passed as a parameter. Optionally, you can also execute another method (onCloseCallback) when the OK button is clicked.
var message = "Alert Dialog ! "; Xrm.Utility.alertDialog(message, onCloseCallback);
The Xrm.Utility.confirmDialog(message, yesCloseCallback, noCloseCallback) method displays a confirmation dialog box that contains an optional message and an OK and a Cancel button. A callback method can be set to run after each of the button is clicked.
var message = "Confirmation Dialog ! "; Xrm.Utility.confirmDialog(message, null, null);
Again in this case, the methods are only available for “Updated Entities”. You can see my previous post to get the list of entities on which this will not work.
