Events

Updated on Oct 1, 2026

This article describes the Blazor Signature events and provides a runnable example with sample event handler implementations.

• OnBlur
• OnChange
• ValueChanged

OnBlur

The OnBlur event fires when the Signature loses focus.

OnChange

The OnChange event represents a user action - confirmation of the current value. It fires when the user presses Enter, or when the component loses focus.

The OnChange event is a custom event and does not interfere with bindings, so you can use it together with models and forms.

ValueChanged

The ValueChanged event fires when signature is fully drawn.
