Question

我有以下代码应该以模态弹出方式运行：

#region events


protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        dt = DataObj.GetDataTable("GetScheduleNames");
        foreach (DataRow myrow in dt.Rows)
        {
            SchedNameLst.Add(Convert.ToString(myrow["ScheduleName"]));
        }
        SchedNameListDD.DataSource = SchedNameLst;
        SchedNameListDD.DataBind();

    }
}

 protected void SchedNameListDD_SelectedIndexChanged(object sender, EventArgs e)
{
    // should be in selected index fired event
    SchedName.Text = SchedNameListDD.SelectedItem.Text;
    string name = SchedNameListDD.SelectedItem.Text;
    dt = DataObj.GetDataTable("GetSchedDetails", name);

    foreach (DataRow myrow in dt.Rows)
    {
        StartTime.Text = myrow["StartTime"].ToString();
        EndTime.Text = myrow["EndTime"].ToString();
    }
    dt = DataObj.GetDataTable("GetSchedDetailsSat", name);
    foreach (DataRow myrow in dt.Rows)
    {
        SatSt.Text = myrow["StartTime"].ToString();
        SatEt.Text = myrow["EndTime"].ToString();
    }
 }


#endregion

当我在下拉列表中更改我的项目选择时，我的selectedIndexChanged事件不会被触发..是这样的吗？

Answer 1

确保您已在控件上启用了AutoPostBack，即AutoPostBack = "true"
通过在Page或UserControl指令中设置EnableViewState="true"，确保启用了viewstate

Answer 2

使用onchange =＆＃34; javascript：__ doPostBack（＆＃39; 下拉列表＆＃39; <＃> Patameters ＆＃39;）＆＃ 34;

在模态弹出窗口中没有触发选定的索引更改事件？
