Sandbox.UI.Button

Sandbox.UI.Button : api/Sandbox.UI.Button

By default Button will have the pointer-events property to none , which mean that no mouse events will get fired.

Make sure to addpointer-events: all; in the SCSS to handle mouse events like onClick in your UI.

Example:

HTML

<Button onclick="@Test">Test Button<Button/>

Button
{
    pointer-events: all;
}
