使用ASP.NET打印Web控件时隐藏页眉和页脚

How can I hide the header like 'Page 1 of 1' and footer (url) when printing a webcontol in ASP.NET?

在ASP.NET中打印webcontol时,如何隐藏像“Page 1 of 1”和页脚(url)这样的标题?

I currently doing by opening a new page on Print button click ande in it

我目前在打印按钮上打开一个新页面,单击其中的ande

protected void Page_Load(object sender, EventArgs e)
{
    if( null != Session["Control"] )
    {
        Control ctrl = ( Control )Session["Control"];
        PrintManager.PrintWebControl( ctrl );
        Session["Control"] = null;
    }
}

This will print the header and footer. How to avoid it?

这将打印页眉和页脚。怎么避免呢?

That setting is configured by the user in their browser. Their is no way to disable it from code. You'r best bet is to include instructions on how to configure/disable the settings.

该设置由用户在其浏览器中配置。他们无法从代码中禁用它。您最好的选择是包含有关如何配置/禁用设置的说明。

You should use CSS styles and specify they apply to a media type of print. See this article for help; http://www.cantoni.org/articles/printstyle

您应该使用CSS样式并指定它们适用于介质类型的打印。请参阅此文章以获取帮助; http://www.cantoni.org/articles/printstyle

Basically create a seperate stylesheet for print styles only. If you want to hide something on the page use { display:none } as one of that elements style attributes. Then link your stylesheet in the HEAD element;

基本上只为打印样式创建单独的样式表。如果要在页面上隐藏某些内容,请使用{display:none}作为其中一个元素样式属性。然后在HEAD元素中链接样式表;

<link href="print.css" media="print" type="text/css" rel="stylesheet" />

For this we are using print class like it

为此,我们使用类似的印刷类

public static void PrintWebControl(Control ctrl)
{
    PrintWebControl(ctrl, string.Empty);
}

public static void PrintWebControl(Control ctrl, string Script)
{
    StringWriter stringWrite = new StringWriter();
    System.Web.UI.HtmlTextWriter htmlWrite = new System.Web.UI.HtmlTextWriter(stringWrite);
    if (ctrl is WebControl)
    {
        Unit w = new Unit(100, UnitType.Percentage); ((WebControl)ctrl).Width = w;
    }
    Page pg = new Page();
    pg.EnableEventValidation = false;
    if (Script != string.Empty)
    {
        pg.ClientScript.RegisterStartupScript(pg.GetType(), "PrintJavaScript", Script);
    }
    HtmlForm frm = new HtmlForm();

    pg.Controls.Add(frm);
    // done changes on below 1 line for unassigned header URL //
    frm.ResolveUrl("");
    frm.Attributes.Add("runat", "server");
    frm.Controls.Add(ctrl);

    pg.DesignerInitialize();

    pg.RenderControl(htmlWrite);
    string strHTML = stringWrite.ToString();
    HttpContext.Current.Response.Clear();        
    HttpContext.Current.Response.Write(strHTML);
    HttpContext.Current.Response.Write("<script>window.print();</script>");
    HttpContext.Current.Response.End();
}

here just change a line in form property and set

这里只需更改表单属性中的一行并设置

frm.ResolveUrl("");

so URl is not visible when page is print..i use it successfuly.

所以当页面打印时,URl不可见..我成功使用它。

If you're using Firefox, and you can have the client install this add-on.

如果您使用的是Firefox,则可以让客户端安装此附加组件。

Otherwise, if you are using Internet Explorer: google for "MeadCo ScriptX"

否则,如果您使用的是Internet Explorer:google for“MeadCo ScriptX”

(FF option is free, IE option is free for basic functionality only)
