c自定义web控件

‘壹’ C#的webbrowser控件如何实现类似手机的拖动效果

需要自定义webbrowser的mousedown和mouseup事件，然后根据位置控制滚动条的位置！
1.引用mshtml;
using mshtml;

2.定义全局变量：
private Point p=new Point(0,0); //用来记录上次鼠标按下时的坐标

3.在form_actived事件中定义事件：
webbrowser1.Document.MouseUp += new HtmlElementEventHandler(Document_MouseUp);

webbrowser1..Document.MouseDown += new HtmlElementEventHandler(Document_MouseDown);

4.定义webbroser的mousedown事件
private void Document_MouseDown(object sender, HtmlElementEventArgs e)
{
p = e.ClientMousePosition; //记录下鼠标按下时的位置并赋值给p
}

5.定义webbroser的mouseup事件
private void Document_MouseUp(object sender, HtmlElementEventArgs e)
{
IHTMLDocument2 document = (IHTMLDocument2)WB1.Document.DomDocument;
document.parentWindow.scrollBy(e.ClientMousePosition.X - p.X, e.ClientMousePosition.Y - p.Y); //要滚动的位置

}

‘贰’ C# 自定义web控件编写

参考一下：在页面引用就可以 这只是简单的自定义控件
namespace MyServerControl
{
[DefaultProperty("Text")]//(打开属性时)默认选择的属性
[ToolboxData("<{0}:ServerControl1 runat=server></{0}:ServerControl1>")]//自定义服务器控件在页面上面显示的标记
public class ServerControl1 : WebControl
{
[Bindable(true)]//是否通常绑定
[Category("外观")]
[DefaultValue("")]
[Description("显示的文本")]//属性的描述
[Localizable(true)]
public string Text
{
get
{
String s = (String)ViewState["Text"];
return ((s == null) ? "[" + this.ID + "]" : s);
}

set
{
ViewState["Text"] = value;
}
}
private string imageurl;
[Description("要显示图片的路径")]//属性的描述
[Category("样式")]
[EditorAttribute(typeof(ImageUrlEditor), typeof(UITypeEditor))]//让属性里面有选择图片的按钮”...“
public string Imageurl
{
get { return imageurl; }
set { imageurl = value; }
}
[Bindable(true)]//是否通常绑定
[Category("字体")]
[DefaultValue("")]
[Description("设置文本框的字体的大小单位为px")]//属性的描述
[Localizable(true)]
public string Fontsize
{
get {
String font = (String)ViewState["Fontsize"];
return ((font == null) ? "14px" : font+"px");
}
set { ViewState["Fontsize"] = value; }
}
protected override void Render(HtmlTextWriter Write)
{
string path="";
if(imageurl!=null)
{
path = this.ResolveClientUrl(Imageurl);//取图片路径对应的在客户端的路径
}
WebColorConverter wcolor = new WebColorConverter();//进行颜色转换为RGB格式//在RGB和color间切换的对象
Write.Write("<input type=\"text\" id=\"" + this.ID + "\" name=\"" + this.ID + "\" style=\"background-color:" + wcolor.ConvertToString(base.BackColor) + " ;background-image:url(" + path + "); font-size:" + Fontsize + "\" value=\"");
Write.Write(Text);
Write.Write("\"/>");
}
}
}

‘叁’ 请教vc中用cwebBrowser2控件实现网页模拟点击的问题

如果只是要实现点击下按钮的话应该可以

你可以遍历所有控件，然后判断是INPUT，判断是BUTTON类型，然后判断ID（通过网站源代码看）是不是这个按钮的，然后就check()就可以了。
C/C++ code

MSHTML::IHTMLElementCollection *objAllElement=NULL;

MSHTML::IHTMLDocument2 *objDocument=NULL;

CString strUrl,strTemp;

strUrl=m_ctrlWeb.GetLocationURL();//得到当前网页的URL

if(strUrl.IsEmpty())

return;

objDocument=(MSHTML::IHTMLDocument2 *)m_ctrlWeb.GetDocument(); //由控件得到IHTMLDocument2接口指针

objDocument->get_all(&objAllElement); //得到网页所有元素的集合

//由于所有页面下载完后都会执行这个函数，所以必须根据URL判断消息来源网页

‘肆’ 如何通过javascript操作web控件的自定义属性

举个例子吧，比如操作TextBox控件，TextBox控件中没有IsNotNull属性，但是可以自己添加一个IsNotNull属性，从而作为一个标记来方便编写程序。

虽然IDE会提示“IsNotNull不是TextBox的属性”这个警告信息但是也不妨碍使用！

代码：
<asp:TextBox ID="TextBox1" runat="server"
IsNotNull="e"></asp:TextBox>
编写Javascript代码：

<script language=javascript
type="text/javascript">
function getClick()
{
var
c=document.getElementById("<%=TextBox1.ClientID %>");

if(c.IsNotNull == 1)
{
alert("IsNotNull is 1");

}
else if(c.IsNotNull == 0)
{
alert("IsNotNull is
0");
}
else
{
alert(c.IsNotNull);
//不是0或者1时会显示IsNotNull的属性值
}
}
</script>

//web.Url=newUri(url);
web.Navigate(url);
//等待网页加载
while(web.ReadyState<WebBrowserReadyState.Complete)Application.DoEvents();
HtmlDocumenthtmldoc=web.Document;//已经获取到html
//下面自己解析
for(inti=1;i<=10;i++)
