c# - ASP.NET刷新UpdatePanel OnClientClick

我有几个更新面板，一个包含一个gridview，另一个包含一个detailsview。我无法在detailsview中获得按钮才能触发gridview更新面板的更新。我已经尝试了几件事（也可以通过c＃来做。）但是，这就是我现在所拥有的...有什么建议吗？ [...我需要“ confirmButton”来触发“ SelectCarUP”中的更新]

          </ContentTemplate>
     </asp:UpdatePanel>
</asp:TableCell>

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

最佳答案

尝试做

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

请参阅this ASP.net forum

要么

在您的按钮上，单击调用SelectCarUP.Update()后的代码内的事件处理程序。它应该更新SelectCarUP面板。有关更多信息，请参考article on MSDN。

要么

在后面的代码中，您可以为此按钮添加触发器（对此不确定）

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

希望这对您有用。
