Change RadzenTabs selected tab from a RadzenTabsItem

Radzen.Blazor Components
1

I'm trying to create a hack to make the RadzenTabs validation aware,
I've created a custom RadzenRequiredValidator that have as a parameter the RadzenTabsItem that it is in, when a validation fails, i want to change the tabs to that tab.
ParentTabItem.Tabs.SelectedIndex = ParentTabItem.Index;
but it dose not seams to work , so as a work around i have a call back event that is change the selectTabIndex which is bind to the RadzenTabs SelectedIndex, this hack works, but is there a way to change the tab directly using the RadzenTabsItem

Herer is my custom validator

@inherits RadzenRequiredValidator

@code {
[Parameter]
public RadzenTabsItem? ParentTabItem { get; set; }

[Parameter]
public EventCallback<int> HaveValidation { get; set; }

protected override bool Validate(IRadzenFormComponent component)
{
    var ok = base.Validate(component);



    if (ParentTabItem is not null)
    {
        if (!ok)
        {
            ParentTabItem.Tabs.SelectedIndex = ParentTabItem.Index;
            // HaveValidation.InvokeAsync(ParentTabItem.Index);
        }
        ParentTabItem.Icon = !ok ? "priority_high" : string.Empty;
        ParentTabItem.IconColor = !ok ? "#EA3323" : string.Empty;
    }
    return ok;
}

}
thanks
