Question

我的datalist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dataList标记：

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

这是sqldatasource：

<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)
{

}

我希望在其中一个事件处理程序中获取与所选行相关联的ThreadID（通过单击datalist中的行）并从所选的特定行中获取ThreadTitle参数。

我怎样才能完成这项任务？

我基本上想要检索我提供给sqldatasource的sql参数，这些参数与点击的特定行有关!!

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

Answer 1

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")
}

Answer 2

我认为，以下代码将起作用：

protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e) {
    DataRowView rowView = e.Item.DataItem as DataRowView;
    int threadID = Convert.ToInt32(rowView["ThreadsID"]);
}

OR

protected void DataList1_SelectedIndexChanged(object sender, EventArgs e) {
        DataRowView rowView = DataList1.SelectedItem.DataItem as DataRowView;
        int threadID = Convert.ToInt32(rowView["ThreadsID"]);
    }
