Question

目标：用户在其中输入名称的文本框应显示数据库中与名称匹配的值的列表。但是，我们实际上必须捕获ID而不是选定的Name。文本框将显示匹配的名称。

平台：VB.NET

我尝试遵循：https://blogs.msdn.microsoft.com/phaniraj/2007/06/19/how-to-use-a-key-value-pair-in-your-autocompleteextender-updated-again/

但是，这是C＃。我的代码如下：

ASPX文件：

<asp:TextBox ID="txtClass1" runat="server" />
<cc1:AutoCompleteExtender Enabled="True" runat="server" ID="nameAuto"  
                        TargetControlID="txtClass1" 
                        ServiceMethod="GetNames" 
                        ServicePath="~/WebService.asmx"    
                        OnClientItemSelected="selectedClass"
                        />

服务：

 Public Function GetNameList(ByVal prefixText As String, ByVal contextKey As String) As ArrayList

    Dim businessLayer as BL = New BL()
    Dim arrLst = businessLayer.GetNameList(prefixText, contextKey) // brings 123~John
    Dim arr2lst As New ArrayList

    For i As Integer = 0 To arrLst.Count - 1
        Dim subItem = arrLst.Item(i).ToString.Split("~")
        arr2lst.Add(AjaxControlToolkit.AutoCompleteExtender.CreateAutoCompleteItem(subItem(0), subItem(1)))
    Next
    Return arr2lst
End Function

aspx中的Javascript函数：

<script type="text/javascript" language="javascript">

    function selectedClass(source, eventArgs) {
        console.log("eventArgs");
        console.log("source");
    }

</script>

在用户类型时，我在控制台中看到错误消息：
