I have a ModalPopupExtender that I have a listview inside of. The problem I am having is if you click on the Update button (when the Listview is show, the page refreshes and hides the popup. How can I force the popup to stay open until the close button is clicked?

<asp:ScriptManager ID="asm" runat="server" />
 <asp:Panel ID="ModalPanel" runat="server" Width="90%" Height="90%" BackColor="Ivory"  >

~~~~~ Listview对象~~~~

~~~~~Listview object~~~~

    <br />
    <asp:Button ID="OKButton" runat="server" Text="Close" />

<asp:ModalPopupExtender ID="mpe" runat="server" TargetControlId="btnOSHA" PopupControlID="ModalPanel" OkControlID="OKButton" />

推荐答案

添加HiddenField控件，并将其用作ModalPopupExtender (mpe)中的TargetControlID，如下所示.

Add a HiddenField control and use it as your TargetControlID of your ModalPopupExtender (mpe) as shown below.

<asp:modalpopupextender id="mpe" runat="server" targetcontrolid="HiddenField1" popupcontrolid="ModalPanel" okcontrolid="OKButton" xmlns:asp="#unknown" />

然后，您需要使用:
，而不是通过TargetControlID自动显示弹出窗口.

Then, instead of automatically showing the Popup thru TargetControlID, you need to use:

mpe.Show();

和关闭:

and for closing:

mpe.Hide();
