Detecting screen resolution in server code?

[Bjorn Sagbakken]

Can screen resolution be detected with server code (in Page_Load) ?

I have tried this:
public int Width =
Convert.ToInt32(System.Windows.Forms.Screen.Primar yScreen.WorkingArea.Width);
public int Height =
Convert.ToInt32(System.Windows.Forms.Screen.Primar yScreen.WorkingArea.Height);

and sure enough, I get a couple of numbers; Width=1024 and Height=738 when
running at 1024x768 - but I also get the same numbers when running at
1280x1024 (?) - so I just don't know what I'm actually reading here.

The idea is to rescale some controls to make the best out of the actual
resolution, and if I could do this server side I would be happy. But if
client script is the only way, well then that's the way.

Anyone with an opinion on this?

Do you mean the resolution on the client machine? You can get in on client
side with javascript as window.screen.width and window.screen.height and
pass these values to server side in hidden input controls.

Have you tried something like

int width = System.Windows.Forms.Screen.PrimaryScreen.Bounds.W idth;
int height = System.Windows.Forms.Screen.PrimaryScreen.Bounds.H eight;

Yes, now I have. I get the same result as before.
But when I read the other answers, I realize this would only give me the
resolution on the server, not on the client.
So a client script is probably the neccessary approach anyway.

Very good idea. Thanks a lot.

Right. So now this works very well:
Height=window.screen.height
I write the height/width into a hidden field. Upon the first UpdatePanel
postback this value is stored in a session variable so I can re-use this on
various actions. Great.

Just one more issue:
Ideally I want to dynamically detect the actual client browser size if this
isn't in maximized mode.
I tried "availHeight" instead of height, but the result is not quite clear
(?)
Any tip?

You will also have to update the values when the user changes the
browser size.

I know. That will be the next task.
