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?

Intellisense is working, EventArgs is a generic base event that knows
nothing about commands.
OnClick="Button_Click"
corresponds to:
protected void Button_Click(object sender, EventArgs e){.. generic event
whereas
OnCommand="Button_Command"
corresponds to :
protected void Button_Command(object sender, CommandEventArgs e){
switch ( e.CommandName ) {
case "Cancel":
// do stuff
Response.Redirect( "RegistrantList.aspx" );
break;
}
}
that's my foggy interpretation of things at hand ;)

Good point about the CommandEventArgs e parameter but the MSDN document
shows the control using an OnCommand="CommandBtn_Click" attribute pair
which is inconsistent with what your comments suggest [would | should]
coincide with one another, e.g. OnCommand="CommandBtn_Command or
OnClick="CommandBtn_Click" wouldn't you think?

After last reply I used the CommandEventArgs e as the parameter for the
click event handler as you reminded and I see what you mean in your last
reply about the name value of the attribute being an arbitrary string.
When the OnCommand attribute is used within a corresponding control
declaration we must use CommandEventArgs e as the parameter in the event
handler but the event handler type can be either <String>_Click or
<String>_Command.
Now, why would we want to choose _Click or _Command? It seems we want to use
_Command when needing to bubble properties up to another event handler but
again I'm still shady on that too. Going to sleep on it tonight. I had an in
patient procedure today (epidural) and the narcotics are all worn out and
I'm really exhausted. Thanks for helping me think through this Dabbler...

I think you are missing my point, the name of the event handler is truly
arbitary, it could be <string>_Click, <string>_Command or <string>_ummagumma.
The attribute name determines the event type, not the attribute value, e.g.
OnCommand or OnClick, not <string>_Command or <string>_anything.
Hope you feel better in the morning ;)

I feel great this morning thanks.
I probably didn't convey it clearly but I understood you. I still need to
really understand the scope of using the OnCommand attribute. Command to
what for example? BTW, its a quibble but I wrote <String>_EventName to
follow the consensus naming convention. An event would not ordinarily be
named using camel case. Are you a maverick ? ;-)
