Dialog Header

Updated on Oct 1, 2026

The header contains the Title and the Close Action button.

There are two ways to define a Dialog title:

• a string Title attribute of the component
• a nested <DialogTitle> render fragment.

The default Title value is null.

You can control the close action via the ShowCloseButton parameter. Its default value is true.

If you don't want to render the header, set the ShowCloseButton to false and don't set a Title.

Example

The following example demonstrates how to set up the title through a template. The close action button is also hidden.
