Question

我遇到了AutoPostBack事件的问题。我的下拉列表的AutoPostBack不起作用。它工作正常，直到我将bootstrap引入混音。

下拉

<asp:DropDownList ID="DropDownList1" runat="server" DataSourceID="namesSQL" 
    DataTextField="Name" DataValueField="EmplID" AutoPostBack="true" 
    CssClass="form-control">
</asp:DropDownList>

SQL数据源

<asp:SqlDataSource ID="namesSQL" runat="server" 
    ConnectionString="<%$ ConnectionStrings:Myapp %>" 
    SelectCommand="SELECT EmplID, EmpName, LastName, 
    { fn CONCAT(EmpName, LastName) } AS Name 
    FROM Employees 
    ORDER BY { fn CONCAT(EmpName, LastName) }">
</asp:SqlDataSource>

数据源工作正常，我列出了它，因为我知道有人会要求它......

已更新

好的，我发现当我将该页面插入另一个主页时，它有效。这是它没有工作的主人。从原来的工作，我格式化了一些div来封装内容部分，并添加了自举链接。
