在Modalpopupextender内部的Datalist按钮中没有触发

问题描述 投票:0回答:1

我有一个datalist,下面有一个按钮可以打开Modalpopupextender。这个modalpopupextender中有一个提交按钮,它没有被触发。请指教。

   <table style="width: 100%">
        <tr>
            <td colspan="2">
                <asp:DataList ID="dl1" runat="server" CellPadding="20" RepeatDirection="Vertical"

                </asp:Panel>
            </td>
        </tr>
    </table>
Above is a datalist inside which there is a modalpopupextender which opens when a button is clicked "btnMessageCoach" . Now when popup gets open there is a message textbox and Send button. But this Send button is not firing on click. Please advice.
asp.net datalist modalpopupextender

您需要对代码进行以下更新:

<asp:Panel ID="Panel3" runat="server"移动到DataList外部,使其不会多次渲染。

要获取服务器端上单击项的coachId,请执行以下操作:

在DataList外添加<asp:HiddenField

<asp:HiddenField ID="hidSelectedID" runat="server" />

添加OnClientClick处理程序onMessage Coach按钮以在隐藏字段中设置id:

    <asp:Button ID="btnMessageCoach" runat="server" 
OnClientClick="javascript:document.getElementById('<%=hidSelectedID.ClientId%>').value='<%#Eval("CoachId")>';" Text="Message Coach" Style="border-radius: 5px; height: 30px; background: #32BC29; width: 180px; font-size: Medium; color: Black;"></asp:Button>

在btnSendMessage_Click句柄内,您可以使用hidSelectedID.Value访问隐藏的字段值
