}

建立後，自動完成功能不顯示滾動條。請教我。

添加一個div來保存y軸上的滾動溢出列表元素將有助於自動完成擴展。

請嘗試以下更改aspx頁面：

<!DOCTYPE html> 

<html xmlns="http://www.w3.org/1999/xhtml"> 
<head runat="server"> 
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 
    <title></title> 
</head> 
<body> 
    <form id="form1" runat="server"> 
     <asp:ScriptManager ID="ScriptManager1" runat="server"> 
     </asp:ScriptManager> 
     <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> 
     <div id="listPlacement" style="height:100px; overflow-y:scroll;" ></div> 
     <ajaxToolkit:AutoCompleteExtender 
      ID="TextBox1_AutoCompleteExtender" 
      runat="server" 
      CompletionInterval="50" 
      CompletionSetCount="40" 
      CompletionListElementID="listPlacement" 
      EnableCaching="False" 
      MinimumPrefixLength="0" 
      ServiceMethod="GetAutoCompTestListAAAA" 
      ServicePath="AutoCompList.asmx" 
      TargetControlID="TextBox1"> 
     </ajaxToolkit:AutoCompleteExtender> 
    </form> 
</body> 
</html>
