执行服务器端code对ModalPopupExtender okcontrolid点击 [英] Execute server side code on ModalPopupExtender okcontrolid clicked

问题描述

我使用ASP.NET和C＃。我想弹出这个小屏幕，然后单击确定按钮时，我想根据输入的弹出更新主屏幕。听起来像它应该是经常的事情。是否有可能，如果是这样，怎么样？

I am using ASP.NET and C#. I want to popup this little screen, then when the OK button is clicked, I want to update the main screen based on the input to the popup. Sounds like it should be a regular thing. Is it possible, and if so, how?

    <cc1:modalpopupextender id="ModalPopupExtender1" runat="server" 
cancelcontrolid="btnCancel" okcontrolid="btnOkay" 
targetcontrolid="txtCosCodeExpCode" popupcontrolid="Panel1" 
popupdraghandlecontrolid="PopupHeader" drag="true" 
backgroundcssclass="ModalPopupBG">
    </cc1:modalpopupextender>

    <asp:panel id="Panel1" style="display: none" runat="server">
<div class="CostCentreExpenseCodePopup" style="background-color:White ; border-style :solid;">
            <div class="PopupHeader" id="PopupHeader">Select Cost Centre / Expense Code</div>
            <div class="PopupBody">
                <p>Cost Centre<asp:DropDownList 
                                            ID="ddlCostCentres1" 
                                            runat="server" 
                                            CssClass="SVSComboBox1" 
                                            AppendDataBoundItems ="True"
                                            AutoPostBack="True" 
                                            style = "width :152px;"
                                            OnSelectedIndexChanged="ddlCostCentres1_SelectedIndexChanged">
                                            <asp:ListItem Text="Please select" Value="0"></asp:ListItem>
                                        </asp:DropDownList></p>

                <p>Expense Code <asp:DropDownList ID="ddlExpCode1" runat="server" CssClass="SVSComboBox1" style = "width :152px;"
                                            AppendDataBoundItems ="True" Enabled="False" Visible ="False">
                                            <asp:ListItem Text="Please select" Value="0"></asp:ListItem>
                                        </asp:DropDownList></p>
            </div>
            <div class="Controls">
                <input id="btnOkay" type="button" value="Done" />
                <input id="btnCancel" type="button" value="Cancel" />
    </div>
    </div>

推荐答案

不要设置 OkControlID ，但使用 ModalPopupExtender1.Hide（）服务器端。然后，你可以先打电话给你的最新情况：code。

Don't set OkControlID but use ModalPopupExtender1.Hide() on server-side. Then you're able to call your update-code first.

您也应该使用服务器按钮，而不是＆LT;输入ID =btnOkay类型=按钮值=完成/＆GT; 和处理他们的点击-event。

You should also use server-buttons instead of <input id="btnOkay" type="button" value="Done" /> and handle their click-event.
