hi all,

 i'm new to .NET(C#), so i need  some advice on making a printer friendly page. let me explain my situation.

 
I have a couple of pagelayouts(aspx)  which are based on a masterpage which has a layout.css style sheet(<link href="/_layouts/layout.css" rel="stylesheet" />). Now on all the pagelayout i have a little imagebutton(print) when pressed will open another page which is a printer friendly one.

Now i have a print.css which hides all the unnecesarry stuff of the page. This print.css will be in the masterpage too, so all pagelayout automatically use this.

 What i want to achieve is the following. When clicking the imagebutton, the same page needs to open, but only with the print.css activated.

I heard that its possible to when clicking the imagebutton to sent a querystring in the url forexample marketsector.aspx?print=true. Now in the masterpage i need to built some kind of control to read this querystring and if print=true to  use the print.css and if not to use the normal layout.css .

 So i have the idea of how this all will need to work, but not so much how to implement it all... i need to knwo the following:

-  When pressing the imagebutton how can i automaticcaly add "?print=true" to my url?

- And how do i retrieve this querystring from the masterpage?

- and now some kinda if else loop in de materpage to choose from the 2 styles?

I have 20 pagelayouts all based on this masterpage and all will have a imagebutton for a printerfriendly page using the print.css. So its obvious to built the control in the masterpage rather then in all the pagelayouts right?

any help and or links to similar topics are welcome !

 i already figured out how to sent the ?print=true query string from the imagebutton... can someone help me to built to control to switch between the normal and print css sheets...

 all help/suggestions are really welcome...
 

 Try this

<link rel="Stylesheet" type="text/css" href="style.css" media="screen" id="stylie" runat="server" />

in code behind:

 Private Sub Login_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If request.querystring("print") = "true" Then
            stylie.Href = "style2.css"
        End If
    End Sub
 

 thanks for the suggestion.. that seems logical.. only i use C# and how do i add a code-behind file to an existing masterpage?

 and if i want to open the page with the print.css in a new browser which command can i use?
 

I did the following i made a control in a seperate printcontrol.cs file. I registered it on the masterpage directives with a tagprefix pc.

printcontrol.cs 

1        public class PrintControl :Page
2        {
3            protected override void OnLoad(EventArgs e)
4            {
5               //base.OnLoad(e);
6                if (Request.QueryString["Print"] == "true")
7                {
8                    this.Response.Write("< link href=\"/_layouts/print.css\" rel=\"stylesheet\" />");
9                }
10               else
11               {
12                   this.Response.Write("< link href=\"/_layouts/grontmij.css\" rel=\"stylesheet\" />");
13               }
14           }
15       }

  now when i added the following line to the masterpage where i initially added the original css..

<pc:PrintControl id="printcontrol1"  ></pc:PrintControl>

but when i try it nothing happens, in fact it doesnt render a thing, so now not even 1 one the styles is loaded... and if i add a runat=server to the printcontrol tag is crashes...

Is something wrong here guys... please help me out... and forgive my coding skills... i'm a newbie... 

Hi,

wiske80:

can someone help me to built to control to switch between the normal and print css sheets...

If you want to switch between the normal and print css sheets, you can try to like below:

 protected void Page_Load(object sender, EventArgs e)
    {
        HtmlLink links = new HtmlLink();
        links.Attributes.Add("rel", "stylesheet");
        if (Request.QueryString["Print"] == "true")
        {
            link.Href = "/_layouts/print.css";
        }
        else
        {
            links.Href = "/_layouts/grontmij.css";
        }
        this.Page.Header.Controls.Add(links);
    }

Hope it helps.

 thanks.. that worked fine... thanks alot for the help
