問題的一個DataList事件

Question

DataList控件：

<asp:DataList ID="DataList2" runat="server" 
        DataSourceID="AllQuestionsResponded" 
        GridLines="Horizontal" DataKeyField="ThreadsID" 
        onselectedindexchanged="DataList2_SelectedIndexChanged"> 
        <ItemTemplate> 

         <asp:LinkButton ID="LinkButton1" runat="server">'<%# Eval("ThreadTitle") %>'</asp:LinkButton> 
         <br /> 
         <br /> 
        </ItemTemplate> 
       </asp:DataList> 

和SQL數據源：

  <asp:SqlDataSource ID="AllQuestionsResponded" runat="server" 
       ConnectionString="<%$ ConnectionStrings:CP_AllQuestionsAnswered %>" SelectCommand="SELECT ThreadTitle, ThreadsID 
FROM Threads 
WHERE ThreadsID IN (SELECT ThreadsID 
FROM Comments 
WHERE UsersID=@UserID) 
" onselecting="AllQuestionAskedDataSource_Selecting"> 

事件背後的代碼：

protected void DataList2_SelectedIndexChanged(object sender, EventArgs e) 
{ 
    Server.Transfer("AnswerQuestion.aspx?x=" + DataList2.DataKeyField + "&question=" + DataList2.SelectedValue + "&time=" + DateTime.Now); 
} 

的事件從未被觸發！無論多少次，我按下按鈕鏈接。爲什麼是:(..

Answer 1

嘗試指定的CommandName選擇。

<asp:LinkButton ID="LinkButton1" CommandName="Select" runat="server">'<%# Eval("ThreadTitle") %>'</asp:LinkButton> 

或者，你可以使用ButtonColumn

<asp:BoundColumn ButtonType="LinkButton" 
        HeaderText="ColumnHeader" 
        DataField="LinkButton" 
        CommandName="Select" /> 

Answer 2

嘗試

<asp:LinkButton ID="LinkButton1" runat="server" command="Select" autopostback="True">
