Message box
A message box asks one question and returns the answer: true for yes, false for no, null for cancel. Use it instead of writing a dialog component when the content is a sentence and two or three buttons.
Acknowledge
With only yesText, the box has a single button. Await the call; it completes when the box closes.
Yes, no and cancel
Three answers map to true, false and null. Name the buttons after their effect, not “Yes” and “No”.
Last answer: none · Not asked yet.
MessageBoxOptions and dialog options
MessageBoxOptions groups the texts; MarkupMessage renders trusted HTML. The second argument takes the usual DialogOptions.
Declared in markup with custom content
A MudMessageBox in the page accepts any content and custom buttons. Open it with ShowAsync through a component reference.
