Gridview无法找到modalpopupextender控件
本文关键字：modalpopupextender 控件 Gridview | 更新日期: 2023-09-27 18:08:41
我有一个列"View" ID= "lnkViewContact"的gridview。点击此链接，将显示注册模式popupextender。这个弹出窗口对所有行都是类似的。但是当我运行它时，我得到的错误是"找不到控件lnkViewContact"。如何解决。另一种选择是通过使用Onclick事件上的链接单击，但我不想做一个回发打开Popupextender。下面是我的代码:

当你提到'一种选择是使用Onclick事件上的链接点击，但我不想做一个回发打开Popupextender '时，这是有点混乱。如果你想要一个OnClick事件，你将不得不进行回发。以下是一个建议。
…这部分是你的代码....
<asp:LinkButton ID="lnkFake" runat="server"></asp:LinkButton>
<cc1:ModalPopupExtender ID="mp1" BehaviorID="behaviorIDmp1" runat="server" PopupControlID="Panl1"
TargetControlID="lnkViewContact" CancelControlID="btnCancel" DropShadow="true" BackgroundCssClass="modalBackground">
</cc1:ModalPopupExtender>…替换为......
<asp:LinkButton ID="lnkFake" runat="server"></asp:LinkButton>
<cc1:ModalPopupExtender ID="mp1" BehaviorID="behaviorIDmp1" runat="server" PopupControlID="Panl1"
TargetControlID="lnkFake" CancelControlID="btnCancel" DropShadow="true" BackgroundCssClass="modalBackground">
</cc1:ModalPopupExtender>在OnClick事件代码后面，这样做来显示弹出
mp1.Show()Gridview中的Linkbutton不能设置为Modalpopupextender的TargetcontrolID，因为在运行时Linkbutton的ID会动态变化。周围的工作是使用LinkButton的Onclick事件，就像在我的情况下，如果有任何验证在modalpopupextender然后验证服务器端的控件。
