MessageBox

Displays a modal message box, also known as a dialog box, that can contain text, buttons, and symbols that inform and instruct the user.

The Wisej.NET MessageBox cannot be instantiated directly. Display messages by calling the static MessageBox.Show method, which accepts parameters for message, title, buttons, and icon configuration.

MessageBox.Show("An unexpected error occurred.", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);

Here's the code for a MessageBox with the title "Error", the text "An unexpected error occurred.", an OK button, and an Error icon. The MessageBox will look like this:

Note that the MessageBox appearance changes based on the theme. The above image uses the Bootstrap theme.

For a full list of properties, methods and events see the API documentation.
