[1]HoverMenuExtender应用

来源: 发布时间: 2013-10-28

AjaxControlToolkit控件，当然是在Ajax下应用。在aspx页面或母版页中应该要写上：

<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>

TargetControlID指定要显示信息的控件，PopupControlID指定鼠标移动上时显示的信息。

<asp:Label id="Label30" runat="server" ForeColor="Blue" Text="帮助！"></asp:Label>
<cc1:HoverMenuExtender ID="HoverMenuExtender1" runat="server" TargetControlID="Label30" PopupControlID="pMessage" PopupPosition="Right" OffsetX="0" OffsetY="15">
</cc1:HoverMenuExtender>

以下为显示信息的Panel。

<asp:Panel ID="pMessage" runat="server" Css Width="300px">
<div>
<div ><strong>
使用帮助</strong></div>
...
</div>
</asp:Panel>

Css如下：

.HoverMenuStyle
{
filter:alpha(opacity=70); /*IE*/
-moz-opacity:0.7; /*MOZ , FF*/
opacity:0.7; /*CSS3, FF1.5*/
background: #fff6bf;
text-align: left;
padding: 5px;
border: 1px solid #ffd324;
z-index: 1;
color:MenuText;
}

效果图：

有关LocalReport、DeviceInfo和PrintDocument的内容已经介绍得差不多了，稍后会给出一个继承自 System.Drawing.Printing.PrintDocument的组件EMFStreamPrintDocument。但是现在，来看一下如何进行自定义纸张票据打印时的页面设置。页面设置窗体如下图所示：

如何添加、删除自定义大小的纸张、枚举系统的打印机？以前在博客园的一篇随笔中参加过讨论，见http://wormday.cnblogs.com/archive/2005/12/22/302635.aspx。当然还是使用Win32 API，以下是我封装的一个关于打印机控制的类[以前用VB实现过比这个类还要多的关于打印机控制的功能，但是在C#中感到还是挺困难的，所以这次只给出了够用的功能：获取当前指定打印机的状态、删除已经存在的自定义纸张、指定的打印机设置以mm为单位的自定义纸张(Form)、获取本地打印机列表、获取本机的默认打印机名称、设置默认打印机、判断打印机是否在系统可用的打印机列表中、判断表单是否在指定的打印机所支持的纸张列表中、判断指定纸张的宽度和高度和在文本框中指定的宽度和高度是否匹配、英尺到厘米的转换]：

来源: 发布时间: 2013-10-28

Html.ActionLink只支持文字链接，现在我们利用C#的扩展方法写一个Html.ActionLinkWithImage()让其支持图片链接的功能。
一、首先新建一个静态类，将命名空间在改在System.Web.Mvc下，代码如下

代码复制 - 运行

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace System.Web.Mvc
{
public static class MyHelpler
{
public static MvcHtmlString ActionLinkWithImage(this HtmlHelper html, string imgSrc, string actionName)
{
var urlHelper = new UrlHelper(html.ViewContext.RequestContext);

string imgUrl = urlHelper.Content(imgSrc);
TagBuilder imgTagBuilder = new TagBuilder("img");
imgTagBuilder.MergeAttribute("src", imgUrl);
string img = imgTagBuilder.ToString(TagRenderMode.SelfClosing);

string url = urlHelper.Action(actionName);

TagBuilder tagBuilder = new TagBuilder("a")
{
InnerHtml = img
};
tagBuilder.MergeAttribute("href", url);

return new MvcHtmlString(tagBuilder.ToString(TagRenderMode.Normal));
}
public static MvcHtmlString ActionLinkWithImage(this HtmlHelper html, string imgSrc, string actionName,string controllerName,object routeValue=null)
{
var urlHelper = new UrlHelper(html.ViewContext.RequestContext);

string imgUrl = urlHelper.Content(imgSrc);
TagBuilder imgTagBuilder = new TagBuilder("img");
imgTagBuilder.MergeAttribute("src", imgUrl);
string img = imgTagBuilder.ToString(TagRenderMode.SelfClosing);

string url = urlHelper.Action(actionName, controllerName, routeValue);

TagBuilder tagBuilder = new TagBuilder("a")
{
InnerHtml = img
};
tagBuilder.MergeAttribute("href", url);

return new MvcHtmlString(tagBuilder.ToString(TagRenderMode.Normal));
}
}
}

二、在view下使用：

代码复制 - 运行

@Html.ActionLinkWithImage(Url.Content("~/Content/images/index_1.gif"), "Index")

@Html.ActionLinkWithImage(Url.Content("~/Content/images/index_2.gif"), "List","Admin", new { id=1})
