選中的索引更改事件未在模態彈出窗口中被觸發？

Question

我有下面的代碼是應該在模式彈出運行：

#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 

我SelectedIndexChanged事件時，我改變我的項目的選擇在下拉列表中.. y是針鋒相對因此不被解僱？

Answer 1

1. 確保您已啓用的AutoPostBack上的控制，即AutoPostBack = "true"
2. 確保ViewState是通過在頁面或用戶控件指令

Answer 2

使用的onchange =「JavaScript設置EnableViewState="true"啓用：__doPostBack（」 Dropdownlist'，'Patameters'）「
