How do I get the Code Review Id in a custom section of the code review page? - visual-studio-2017

Question

I am writing a visual studio extension that has a section on the code review page. I would like access to the information about the rest of the code review page, specifically what code review is current on the page being displayed. I should be able to access the workitemId but so far I have not figured out how.
Edit
Using Cole's suggestion I have accessed the PageContent but I do not know what type I should cast the content to. Nor do I know when it will be available. I would like access both when I initialize my section, and later. Here is my code when I try to initialize the section:
public override object SectionContent
{
get
{
if (base.SectionContent == null)
{
var teamExplorerPage = this.GetService<ITeamExplorerPage>();
var pageContent = teamExplorerPage.PageContent;
this.model.CodeReviewId = pageContent;
base.SectionContent = new CodePlusTeamExplorerSectionView(this.ServiceProvider, this.model);
}
return base.SectionContent;
}
}
When I debug the code I see that a DataContext is available on the PageContent, but I do not know what type to cast the pageContent (orITeamExplorerPage) to, to gain access to it. Also the DataContext has a CodeReviewId property which seems like the value I need but it is null at this point of the Lifecycle. If I want to retrieve some additional data based on the CodeReviewId when/where is it available?

I am still trying to figure out how to get it earlier in the lifecycle of the page but from an event like a button click in the page I can retrieve the value using reflection. This seems like a bit of a hack, perhaps someone else has a better way, but here it is.
private void Button_Click(object sender, RoutedEventArgs e)
{
var teamExplorer = this.GetService<ITeamExplorer>();
var currentPage = teamExplorer.CurrentPage;
var currentContent = currentPage.PageContent;
Type type = currentContent.GetType();
PropertyInfo pi = type.GetProperty("DataContext");
var dataContext = pi.GetValue(currentContent);
Type contextTypetype = dataContext.GetType();
PropertyInfo contextTypePi = contextTypetype.GetProperty("CodeReviewId");
var codeReviewId = contextTypePi.GetValue(dataContext);
var context = new Dictionary<string, object>();
context.Add("WorkItemId", codeReviewId);
teamExplorer.NavigateToPage(new Guid(TeamExplorerPageIds.ViewCodeReview), context);
}
