Move to next steps in code (RadzenSteps)

In general we don't recommend setting properties of components directly as this rarely updates the UI and is against the Blazor declarative nature. What you should do instead is create a property that stores the selected index and update it instead. Then use @bind-SelectedIndex so it is kept in sync.

<RadzenSteps @bind-SelectedIndex="@selectedIndex">

void Button0Click()
{
  selectedIndex = 1;
}
