Is there a way to have a base class for a razor's code behind?

I have CampaignPage.razor:

@page "/Manager/Campaign"@implements IDisposable<PageTitle>Campaign</PageTitle><EditForm EditContext="EditContext"          OnValidSubmit="HandleValidSubmitAsync"          OnInvalidSubmit="HandleInvalidSubmitAsync"          Context="EditFormContext">...

And I have CampaignPage.razor.cs:

    public partial class CampaignPage    {...

Is there some way I can have:

    public partial class CampaignPage : OrganizationPage    {...

I tried doing this as:

public class OrganizationPage : ComponentBase{...

but that got me compiler errors.
