我有一个带有“View”ID =“lnkViewContact”列的gridview。点击此链接注册将显示modalpopupextender。所有行的弹出窗口类似。但是当我运行它时，我得到的错误是“找不到控制lnkViewContact”。如何解决。另一种方法是在链接点击上使用Onclick事件，但我不想为打开Popupextender做回发。以下是我的代码：

当你提到'一种替代方法是通过链接点击使用Onclick事件但是我不想回复打开Popupextender时，这有点令人困惑。 '如果你想要一个OnClick事件，你将不得不进行回发。以下是建议。
.....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，执行此操作以显示弹出窗口
mp1.Show()

Gridview中的Linkbutton不能设置为Modalpopupextender的TargetcontrolID，因为在运行时链接按钮的ID会动态地改变。解决方法是使用LinkButton的Onclick事件，就像我的情况一样，如果modalpopupextender中有任何验证，那么验证服务器端的控件。
