Question

asp.net中怎么可以把div标签当做服务器控件来使用呢?

比如打个比方,服务器控件双击的话,可以直接进入后台代码区,但是DIV默认的情况下是用户控件来使用的,但我想当做服务器控件使用并且可以产生单击事件.应该怎么做?
不可以,我试过了,不行啊!当双击的时候还是进入javaScript语言.跟本就不能在服务器端运行.

Answer 1

要单机事件！就要写成服务器控件！自己写个事件！
class Longn : WebControl, IPostBackEventHandler, INamingContainer
{
public Longn()
: base(HtmlTextWriterTag.Div)
{ }

private string Text
{
get;
set;
}
protected override void RenderContents(HtmlTextWriter writer)
{
writer.AddAttribute(HtmlTextWriterAttribute.Value, Text);
writer.AddAttribute(HtmlTextWriterAttribute.Name, this.ClientID);
writer.AddAttribute(HtmlTextWriterAttribute.Type, "text");
writer.RenderBeginTag(HtmlTextWriterTag.Input);
writer.AddAttribute(HtmlTextWriterAttribute.Onclick,Page.ClientScript.GetPostBackEventReference(this,"onclick"));
writer.AddAttribute(HtmlTextWriterAttribute.Value, "确定");
writer.AddAttribute(HtmlTextWriterAttribute.Type, "button");
writer.RenderBeginTag(HtmlTextWriterTag.Input);
writer.RenderEndTag();
// base.RenderContents(writer);
}
protected override void OnLoad(EventArgs e)
{
Text = HttpContext.Current.Request.Form[this.ClientID];
base.OnLoad(e);
}
public event EventHandler Onclick;
public void RaisePostBackEvent(string eventArgument)
{
if (Onclick != null)
{
Onclick(this, EventArgs.Empty);
OnBubbleEvent(eventArgument, new CommandEventArgs(Text, "ppp"));
}
}
protected override bool OnBubbleEvent(object source, EventArgs args)
{
bool fl = false;
CommandEventArgs cmd = args as CommandEventArgs;
if (cmd != null)
{
fl = true;
HttpContext.Current.Response.Write(cmd.CommandName);
}
return fl;
}

}

Answer 2

在DIV中加上 runat="server" 如果要在后台访问，加id=“名字”

Answer 3

在DIV中加上 runat="server"
-----------------------------------
你还是多看书吧
要用容器类控件用<asp:Panel></asp:Panel>吧

Answer 4

runat="server" id="divID",后台直接判断divID了
