Problem with a datalist event

The DataList:

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

           开发者_如何学JAVA              <asp:LinkButton ID="LinkButton1" runat="server">'<%# Eval("ThreadTitle") %>'</asp:LinkButton>
                        <br />
                        <br />
                    </ItemTemplate>
                </asp:DataList>

And the sql dataSource:

           <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">

The code behind event:

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

The event never gets triggered!! no matter how many times I press the button link.. Why is that :( ..

Try

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

Try specifying CommandName for selection.

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

Alternatively, you could use a ButtonColumn

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