一、UserControl調用所在頁面的其他內容（代理實現）

UserControl代碼

?

Code
using?System;
using?System.Collections.Generic;
using?System.Linq;
using?System.Web;
using?System.Web.UI;
using?System.Web.UI.WebControls;
using?System.Web.UI.HtmlControls;
using?System.Collections;

public?partial?class?UserControl_Welcome?:?System.Web.UI.UserControl
{
????public?delegate?void?ButtonClickEventHandler(object?sender,?EventArgs?e);
????public?event?ButtonClickEventHandler?ButtonClick;
????protected?void?Page_Load(object?sender,?EventArgs?e)
????{
???????
????}
????protected?void?btnOrder_Click(object?sender,?EventArgs?e)
????{
????????ButtonClick(sender,e);
????}
}

?

頁面代碼

Code
using?System;
using?System.Collections.Generic;
using?System.Linq;
using?System.Web;
using?System.Web.UI;
using?System.Web.UI.WebControls;
using?System.Web.UI.HtmlControls;
using?System.Text;

public?partial?class?_Default?:?System.Web.UI.Page
{

????protected?void?Page_Load(object?sender,?EventArgs?e)
????{
????????Welcome1.ButtonClick?+=?new?UserControl_Welcome.ButtonClickEventHandler(Welcome_ButtonClick);

????}
????public?void?Welcome_ButtonClick(object?sender,?EventArgs?e)
????{
????????TabContainer1.ActiveTabIndex?=?1;
//由于用的AJAX控件，所以完成后AJAX控件要手動更新
????????UpdatePanel5.Update();
????}

?

二、javascript實現部分打印

??? 1、在頁面的代碼頭活末尾部處加入JavaScript：

Code
<script?language=javascript>???
function?doPrint()?{???
bdhtml=window.document.body.innerHTML;???
sprnstr="<!--startprint-->";???
eprnstr="<!--endprint-->";???
prnhtml=bdhtml.substr(bdhtml.indexOf(sprnstr)+17);???
prnhtml=prnhtml.substring(0,prnhtml.indexOf(eprnstr));???
window.document.body.innerHTML=prnhtml;???
window.print();???
}???
</script>? ??? 2、在頁面正文處加上<!--startprint-->與<!--endprint-->標識。

??? 3、添加打印按鈕，執行JavaScript
