Force Validate on Step

The Change even will not fire if validation fails. Here is the actual implementation.

internal async System.Threading.Tasks.Task SelectStep(RadzenStepsItem step, bool raiseChange = false)
    {
        var valid = true;

        if (EditContext != null)
        {
            valid = EditContext.Validate();
        }

        var newIndex = steps.IndexOf(step);

        if (valid || newIndex < SelectedIndex)
        {
            SelectedIndex = newIndex;

            if (raiseChange)
            {
                await Change.InvokeAsync(SelectedIndex);
                await SelectedIndexChanged.InvokeAsync(SelectedIndex);
                StateHasChanged();
            }
        }
    }
