How do I get absolute position deriving from Control instead of WebControl?

[Teemu Keiski]

I remember Nikhil Kothari discussing about this at ASP.NET Forums and he
said it is impossible unless you derive from WebControl.

I have a server control that I derived from
System.Web.UI.WebControls.WebControl. I want the change it to derive from
System.Web.UI.Control so that it does not have all the extraneous
properties. Like a superfluous third nipple, I want them gone.

I can live with not having Height, Width, or TabIndex. I used to just take
these properties and insert them into the content I produced from my
overridden Render. I can implement these myself. No problem

I used to take the Attributes property, grab Style from if and plop it in my
rendered content to absolutely/relatively position my control. The
Attributes property never existed in Control.

How can I get the position of my control if the page is in GridLayout or
FlowLayout when deriving from Control?

-------vbcode-------
Protected Overrides Sub Render(ByVal output As System.Web.UI.HtmlTextWriter)
strObjectText = Replace(strObjectText, "[ABSPOSTOKEN]",
Me.Attributes("style"))
Return strObjectText
End Sub

I very much doubt that. Logically it doesn't make sense. If WebControl
derives from Control, then how does WebControl do it? Somewhere someone
wrote the code to posittion a WebControl. All I want is that code, you know?

Yeah, it doesn't. I believe the IDE has also something to say about that (as
controls are positioned there, although it just should be attributes that
handle the placing) . Sure it is coded somewhere. You might just need
appropriate tools to dig it out.

I tackle this "resizing and moving" deriving from Control, about a year and
half ago, just as an experiment while learning how the design-time support
worked.

The main issue is that the provided designers, when it comes to moving and
resizing were built for handling with WebControl-derived classes only, you
can notice that looking at all the explicit checks that ControlDesigner
makes looking if its designing a WebControl-derived class. This sounds
pretty logical also, as WebControl offers the minimum required
functionallity that is needed in order to be moved and resized while Control
doesn't provide that.

That said, you *could* actually make some of this stuff work for a
Control-derived class. I remember having coding a Control-derived class that
could be resized and it worked okay. But the additional code required isn't
worth it when compared to inheriting from WebControl (even if you may be
inheriting some stuff you don't really want). After giving it a shot, I've
always recommended several times in many posts to inherit from WebControl in
order to get this funcionallity.

btw, it has been publicy said that vNext will include some kind of
intermeditate control between WebControl and Control just to provide this
functionallity.
