Detecting User Screen Resolution
|
 |
|
To detect a user's screen resolution the use of some type of client-side
script will be necessary. Below you will see a javascript example that can be
used to detect the screen resolution:
|
|
|
|
res = “&res=“ + screen.width + “x“ + screen.height + “&d=“ +
screen.colorDepth
top.location.href = “detectscreen.aspx?action=set“ +
res
|
|
|
The above code needs to be placed within script tags and is written as if it
were being run on a page named detectscreen.aspx. The server side code that can
then be used to place the screen resolution values into a session variable would
be:
|
|
if(Request.QueryString[“action“] != null){
Session[“ScreenResolution“] =
Request.QueryString[“res“].ToString();
Response.Redirect(“default.aspx“);
}
|
|
|
The above server-side code would be placed in the Page_Load method of the
detectscreen.aspx page. To use the detectscreen.aspx you could either set your
website to call it first or you could redirect to this page from your existing
main page.
