ASP.NET刷新UpdatePanel OnClientClick

Question

我有幾個更新面板，其中一個包含gridview，另一個包含detailsview。我無法在detailsview中獲得按鈕來觸發gridview更新面板的更新。我已經嘗試了幾件事（從c＃做起來也沒問題..）但是這裏是我現在擁有的......任何建議？ [...我需要 「confirmButton」 在 「SelectCarUP」 來觸發更新]

<script type="text/javascript"> 
function refreshGV() { 
      __doPostBack("<%= SelectCarUP.ClientID %>", ""); 
     }  
</script> 

Answer 1

嘗試做

ScriptManager.GetCurrent(this).RegisterAsyncPostBackControl(this.confirmButton); 

參考this ASP.net forum

OR

在您按一下按鈕代碼隱藏內部的事件處理程序調用SelectCarUP.Update()它應更新SelectCarUP面板。欲瞭解更多信息，請參閱article on MSDN。

OR

在後面的代碼，你可以爲這個按鈕添加觸發器（不知道這一點）

SelectCarUP.Triggers.Add(new AsyncPostBackTrigger() 
{ 
    ControlID = confirmButton.UniqueID, 
    EventName = "Click" 
}); 

希望這對你的作品。
