Question

I am debugging an application to comprehend the steps until an event of interest.

Didn't find an explanation here: https://msdn.microsoft.com/en-us/library/dd409859.aspx (Call Hierarchy)

Who can explain what "Call Sites" and "Location" are intended for?

UPDATE Based on the answer that it is character number.

My guesses are that:

Call Sites are the objects in memory calling the method.
Location has the ClassName | FileName - (LineNumber, ??)

What is the 9 for?

You're half correct. The "Call Sites" column are the lines in the source itself from where that specific function is being referenced.

The "Location" column is the actual file, line number and character position the specified call is referenced at.

So in the image you posted, the first line reads:

ReportPanels(0).Initialize(GlobalVariables.employee, expd) | ReportView.vb - (30,9)

This reads as:

A call to Initialize is being made by ReportPanels(0) in the file ReportView.vb on line 30 at character position 9 (white space in front is included in this count).

I hope that can help.
