Can Page_Load() Be Async

Can a Page_Load() method be async? I ask as if I have declared as such

protected void Page_Load()

Everything loads as it should. If I have it declared as such
protected async void Page_Load()

the Page_Load() breakpoint is not hit, nor does the catch() block get hit.

Now I am trying to set my Page_Load() method as async in order to have 3 different stored procedures execute to completion before the page is fully rendered. If I do not have my Page_Load() method as async I get this compile error:

The await operator can only be used with an async method.

My code is as such.

private DataSet ds1 = new DataSet();
private DataSet ds2 = new DataSet();
private DataSet ds3 = new DataSet();

protected async void Page_Load(object sender, EventArgs e)
 if (!IsPostBack)
    var task1 = GetStoreInfo();
    var task2 = GetSalespersonInfo();
    var task3 = GetManagerInfo();
    await System.Threading.Tasks.Task.WhenAll(task1, task2, task3);

async System.Threading.Tasks.Task<DataSet> GetStoreInfo()
  ds1 = RunStoredProcedureToReturnThisData();
  return ds1;

async System.Threading.Tasks.Task<DataSet> GetSalespersonInfo()
  ds2 = RunStoredProcedureToReturnThisData();
  return ds2;

async System.Threading.Tasks.Task<DataSet> GetManagerInfo()
  ds3 = RunStoredProcedureToReturnThisData();
  return ds3;

protected void PopulateAll()
  //Bind the different returned datasets

Method 1

Scott Hanselman has the magic to use async with ASP.NET lifecycle events here

Method 2

No the ASP.NET design dose not call this method using any form of Task Await, so it cannot be Asnyc
