问题描述

我试图在表单上添加modelpopExtender控件，并为registring标记前缀添加引用标记

作为'ajax'但仍然出错。下面的代码中会出现什么问题。

 <％@    注册    assembly   =  AjaxControlToolkit   命名空间  =  AjaxControlToolkit    tagprefix   =  ajax   ％>  
< ; ajax：ModalPopupExtender ID =   mpeUser runat =    server 
 TargetControlID =   hfUserID 
 PopupControlID =    pnlAddPopup 
 BehaviorID =   mpeUserBehavior 
 DropShadow =   true 
 CancelControlID =   imgClose 
 PopupDragHandleControlID =   popupheader /> 

解决方案

将此添加到顶部源码和查看天气所有的dll都可用。\

 <％@    注册    assembly   =  AjaxControlToolkit   命名空间  =  AjaxControlToolkit    tagprefix   =  asp   ％>  

Am trying to add modelpopExtender control on form and also added reference tag
for registring tag prefix as a 'ajax' but still I get error . What will be the problem in the code below.

<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="ajax" %>

        TargetControlID="hfUserID"
        PopupControlID="pnlAddPopup"
        BehaviorID="mpeUserBehavior"
        DropShadow="true"
        CancelControlID="imgClose"
        PopupDragHandleControlID="popupheader"  />
