Telerik UI for Windows Phone by Progress

This article describes how the message box info can be customized.

When the ApplicationUnhandled message is encountered a message box will be displayed to the user, inviting them to send an error report. Here is how the default message looks like:

Application Error Default Message

The default message can be easily changed by creating a new MessageBoxInfo. The MessageBoxInfo contains the following properties that will change the appearance of the MessageBox: Title; Content; Buttons. Here is an example of how to change the info:

diagnostics.MessageBoxInfo = new MessageBoxInfoModel()
    Title = "An error occured",
    Content = "Would you like to send a report that will help us resolve it faster?",
    Buttons = MessageBoxButtons.YesNo
