asp.net – Handles子句需要在包含类型或其基类型之一中定义的WithEvents变量

我收到了错误

Handles clause requires a WithEvents variable defined in the containing type or one of its base types.

在以下代码中..

Public Sub selCurrentManuf_SelectedindexChanged(ByVal sender As System.Object,ByVal e As System.EventArgs) _
    Handles selCurrentManuf.SelectedindexChanged

    End Sub

随附的下拉列表如下……

<asp:DropDownList  
   OnSelectedindexChanged="selCurrentManuf_SelectedindexChanged" 
   selectedvalue='<%#Container.DataItem("c1_manufidcurrent")%>' 
    ID="selCurrentManuf" 
    Runat="Server" 
    DataTextField="c4_Desc" 
    DataValueField="c4_manufid"
    DataSource="<%# GetCurrentManuf() %>" 
    autopostback="true" 
 ></asp:DropDownList>

解决方法

升级旧页面时遇到此问题.问题在于Inherits属性@Page指令有错误的命名空间.

>更正Inherits属性的名称空间>删除设计器文件中的命名空间或在设计器代码中与其匹配
