Uses a MessageDialog for displaying dialogs, customizing commands, and changing the default button.

Message dialog sample

Shows how to use a MessageDialog for displaying dialogs, setting commands and the actions they will perform, and changing the default button.

Note: This sample is part of a large collection of UWP feature samples. You can download this sample as a standalone ZIP file from docs.microsoft.com, or you can download the entire collection as a single ZIP file, but be sure to unzip everything to access shared dependencies. For more info on working with the ZIP file, the samples collection, and GitHub, see Get the UWP samples from GitHub. For more samples, see the Samples portal on the Windows Dev Center.

The Windows.UI.Popups namespace contains the MessageDialog class. You can use this class to present an urgent message that the user must acknowledge before continuing, or to present an urgent question that the user must answer.

Note The Windows universal samples require Visual Studio to build and Windows 10 to execute.

To obtain information about Windows 10 development, go to the Windows Dev Center

To obtain information about Microsoft Visual Studio and the tools for developing Windows apps, go to Visual Studio

  3. Starting in the folder where you unzipped the samples, go to the Samples subfolder, then the subfolder for this specific sample, then the subfolder for your preferred language (C++, C#, or JavaScript). Double-click the Visual Studio Solution (.sln) file.
  4. Press Ctrl+Shift+B, or select Build > Build Solution.

Run the sample

The next steps depend on whether you just want to deploy the sample or you want to both deploy and run it.
