Question

我想在将一些数据保存到数据库后尝试弹出窗口。使用ConfirmButtonExtender和ModalPopupextender时，它会询问TargetControlID。所以我已经将TargetcontrolID作为提交按钮。因此，无论何时单击提交按钮，它都会首先显示弹出窗口“您的密码已成功保存”。关闭弹出窗口后，它会将信息保存在数据库中。情况并非如此。它必须首先将信息保存在数据库中，如果成功保存密码，则应显示弹出窗口。你认为我应该改变什么？请帮忙..

<cc1:ConfirmButtonExtender DisplayModalPopupID="ModalPopupExtendersave" ID="ConfirmButtonExtendersave"
    runat="server" TargetControlID="imgbtnSubmit">
</cc1:ConfirmButtonExtender>
<cc1:ModalPopupExtender ID="ModalPopupExtendersave" runat="server" TargetControlID="imgbtnSubmit" BackgroundCssClass="modalBackground"
    OkControlID="btnOK" PopupControlID="pnlPopup" >
</cc1:ModalPopupExtender>




protected void imgbtnSubmit_Click(object sender, ImageClickEventArgs e)
{
    if (txtpassword1.Text != "" && txtpassword2.Text != "" && txtpassword1.Text == txtpassword2.Text)
    {
        Savepassword();

        if (Savepassword())
        {
            ModalPopupExtendersave.Show();
            pnlPopup.Visible = true;
        }
        else
        {
            lblerror.Text = "Error in saving password";
        }
    }

}

谢谢大家!!

Answer 1

添加可见等于false的LinkButton或Button Control并将其设置为TargetControlID，然后在代码后面调用ModalPopupExtender控件的Show方法。

我同意DEVMBM - 这是一个例子：

<script runat="server">
    protected void btnShowModal_Click(object sender, EventArgs e)
    {
        // do stuff here - e.g. save password to database

        // show modal popup
        mpeModalDemo.Show();
    }
</script>

<asp:ImageButton
    ID="btnShowModal"
    OnClick="btnShowModal_Click"
    CausesValidation="false"
    runat="server" />

<asp:Button
    ID="btnFakeTarget"
    CausesValidation="False"
    Style="display: none"
    runat="server" />

<ajax:ModalPopupExtender
    ID="mpeModalDemo"
    BackgroundCssClass="modalBackground"
    PopupControlID="pnlModalDemo"                    
    TargetControlID="btnFakeTarget"
    PopupDragHandleControlID="pnlModalDemo"
    runat="server" />

<asp:Panel
    ID="pnlModalDemo"
    style="display:none;"
    runat="server">

    <asp:UpdatePanel ID="updModalDemo" UpdateMode="Conditional" runat="server">
        <ContentTemplate>

            <style type="text/css">
                .modalBackground {
                    background-color: #000000;
                    filter: alpha(opacity=40);
                    opacity: 0.7;
                }
            </style>

            <!-- modal popup content here -->

        </ContentTemplate>
        <Triggers>
            <asp:AsyncPostBackTrigger ControlID="btnShowModal" EventName="Click" />
        </Triggers>
    </asp:UpdatePanel>
</asp:Panel>
