Ajax自动完成扩展程序在vb .net中不起作用 [英] Ajax Autocomplete extender is not working in vb .net

问题描述

嗨专家，

我想在我的项目中添加ajax autocomplete extender，它是在vb中创建的。

但是服务方法没有调用。它工作不正常请帮我解决这个问题。



我的代码是

 <   asp：TextBox     ID   =  txtSearch    runat   =  server    AutoCompleteType   =  FirstName   >  <   / asp：TextBox  >  
 <   asp：AutoCompleteExtender  < span class =code-attribute>   ID   =  ACEtxtSearch    runat   =   server    MinimumPrefixLength   =  0  
   
   ServiceMethod   = < span class =code-keyword> GetCompletionList   已启用  =  True    TargetControlID   =  txtSearch    
   
   EnableCaching   =  true    FirstRowSelected   =  true  
   
   CompletionInterval   =  10    CompletionSetCount   =  10    CompletionListCssClass   =  completionList    CompletionListItemCssClass   =  listItem  
   
   CompletionListHighlightedItemCssClass   =  itemHighlighted > ;  
 <   / asp：AutoCompleteExtender  >  

vbcode

< WebMethod（）> _ 
 函数 GetCompletionList（ ByVal  prefixText  As  字符串， ByVal  count 作为 整数）作为 字符串（）
 
 结束 功能 

请帮我解决这个问题

提前谢谢

解决方案

更改你的网页方法签名如下

< system.web.script.services.scriptmethod（），> System.Web.Services.WebMethod（）> _ 
 公开 共享 功能 GetCompletionList（ ByVal  prefixText  As   String ，< span class =code-keyword> ByVal  count 作为 整数）作为列表（  字符串）
 
 
 结束 功能 

最好在 ASP.Net中的AJAX AutoCompleteExtender示例中关注词干[ ^ ]

change your web method signature as below

Public Shared Function GetCompletionList(ByVal prefixText As String, ByVal count As Integer) As List(Of String)


End Function
