c# - 获取数据列表行详细信息

Question

我的数据列表中有以下 itemTemplate

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

            </ItemTemplate>

这是我的数据列表标记:

   <asp:DataList ID="DataList1" runat="server" 
            DataSourceID="AllQuestionAskedDataSource"
            GridLines="Horizontal" DataKeyField="ThreadsID" >

这是 sql 数据源:

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

我正在尝试使用以下事件处理程序之一:

protected void DataList2_SelectedIndexChanged(object sender, EventArgs e)
{

}
protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
{

}

我想在其中一个事件处理程序中获取与所选行关联的 ThreadID(通过单击数据列表中的行)并从所选的特定行获取 ThreadTitle 参数..

我怎样才能完成那个任务？

我主要是想检索输入到 sqldatasource 中的与单击的特定行相关的 sql 参数!!

自己解决了:

    protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
{
    LinkButton link = (LinkButton)e.Item.FindControl("LinkButton1");
    string threadTitle = link.Text;

    string recordID = (DataList1.DataKeys[e.Item.ItemIndex]).ToString();
    string special = "";
}
enter code here

你可以这样做..

protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
{
    // Will give you current data key value
    Int32 threadID = Convert.ToInt32(e.CommandArgument); 
    // if you want value of your control
    (ControlTypd)e.Item.FindControl("ControldId")
}
