When I use e. in an event handler all Intellisense wants to show me is:

// Event handler
protected void BuildNewFileButton_Click(Object sender, EventArgs e)
{
   // can only 'see" these properties of e
   e. [Equals | GetHashCode | GetType | ToString ]
   // can only 'see" these properties of sender
   sender.[Equals | GetHashCode | GetType | ToString ]
}

// BuildNewFileButton control declaration
<asp:Button ID="BuildNewFileButton"
       OnCommand="BuildNewFileButton_Click"
       CommandName="FileStructure"
       CommandArgument="NoExtensions"
       Text="Build New File"
       runat="server"/>

The control declares a CommandName and CommandArgument and even though they
are properties documentation at MSDN shows they can be referenced (get) the
CommandArgument property through e as follows...

// Get value of CommandArgument
protected void BuildNewFileButton_Click(Object sender, EventArgs e)
{
   if(e.CommandArgument == "NoExtensions")
   // do something...
}

I've read the documents at MSDN [1,2] but I really still don't get how to
use an [OnCommand | OnClick] method with CommandName, and CommandArgument
properties...

...What am I failing to understand here?
