Converting from asp to asp.net with c#

[Michelle Sollicito eBarster]

Ok I know a lot of asp but not a lot of asp.net and C# so please bear
with me. I need some help converting..

In my asp project I have some styles in my head tag that change
according to a parameter passed in in the query string - fontfamily
is the variable that I store the value of the parameter in within my
asp code, and then I place that into the styles see below..

<style type="text/css">
a:link,a:visited,a:hover,a:active{font...
..ebartext{font-family:<%=fontfamily%>;...
..price{font-family:<%=fontfamily%>;fon...
..textfont{font-family:<%=fontfamily%>;...
..{font-family:arial,sans-serif;font-si...
table{background-color:transparent;}
..ebaylogo{position:absolute;z-index:40...
..ebarlogo{position:absolute;z-index:40...
..ebarlogotext{font-family:arial,sans-s...
..ebarcontainer{position:absolute;left:...
..clipdiv{position:absolute;left:0px;to...
</style>

I am not sure how to change my stylesheet from within c# and replace
it with a value passed in as a parameter.

I have gotten the value into the string variable fontfamily, but not
sure how to place that within the style??

//in my c# code default.aspx.cs I get the parameter passed in fine..
string fontfamily = "" + Request.QueryString["fontfamily"];

Can anyone help?

In ASP.NET you will need to do this from within one of the Page events, such
as Load. Here is a class I wrote (with some help from the internet and these
newsgroups):

public class CustomStyle : System.Web.UI.WebControls.Style
{
private System.Web.UI.CssStyleCollection currstyles;

public CustomStyle(System.Web.UI.CssStyleCollection custom) {
this.currstyles = custom; }
public CustomStyle(string cssvalue)
{
System.Web.UI.CssStyleCollection tempstyle = new
System.Web.UI.WebControls.WebControl(System.Web.UI.HtmlTextWriterTag.Unknown).Style;
tempstyle.Clear();
tempstyle.Value = cssvalue;
this.currstyles = tempstyle;
}

protected override void
FillStyleAttributes(System.Web.UI.CssStyleCollection
attributes,System.Web.UI.IUrlResolutionService urlResolver)
{
base.FillStyleAttributes(attributes, urlResolver);
foreach (string currkey in this.currstyles.Keys) { attributes[currkey] =
this.currstyles[currkey]; }
}
}

In your Page's Load event use a statement similar to the following:

this.Header.StyleSheet.CreateStyleRule(new CustomStyle("font-size:12px;"),
null, ".style1");

You will notice that this statement includes two key parts, the
CreateStyleRule method, which you can see details about at:
ms-help://MS.VSCC.v80/MS.MSDN.v80/MS.NETDEVFX.v20.en/cpref13/html/M_System_Web_UI_IStyleSheet_CreateStyleRule_3_9de1b1b6.htm
For the CreateStyleRule method you will be supplying three parameters, the
Style object returned by a new CustomStyle, null, and a String specifying
the CSS selector.

And the CustomStyle constructor. Although the CustomStyle class has two
constructors, the only one I ever use is the second one, which simply takes
a String of CSS declarations, just as you would enter them in a *.css file,
<style> tags, or HTML style attribute.

It took me a while and a lot of help to figure all this out (I actually got
the original CustomStyle class online, but I had to modify it to include the
second constructor), and I have been doing ASP.NET for a couple years now,
so don't feel bad about not knowing what to do. Hopefully everything I have
supplied will be enough to fix your problem. Good Luck!
