Question

对不起，我正在重复这个问题。相反，我不得不重复它。我最后一次发布这个，我得到了答案。我用Google搜索了3个多小时，找到答案。下面是链接按钮和模式弹出窗口的html。链接按钮位于选项卡面板内/上，自动回发设置为true。

<asp:LinkButton ID="lnkAddNewAddress" runat="server" OnClick="lnkAddNewAddress_Click">Click Here To Add New Address</asp:LinkButton>
                                        <asp:ModalPopupExtender ID="lnkAddNewAddress_ModalPopupExtender" runat="server" BackgroundCssClass="modalBackground"
                                            DynamicServicePath="" Enabled="True" PopupControlID="pnlMyAddressBook" TargetControlID="lnkAddNewAddress"
                                            ViewStateMode="Enabled" >
                                        </asp:ModalPopupExtender>

我希望linkbutton的clickevent能够触发未发生的事情。但是点击该链接会打开模态弹出扩展器（这也是我想要的）...如何进入click事件。我知道这里可以避免回发因为模态弹出窗口可能...但我不解决它....

保存按钮上的代码：

  if(hdnfld.Value.ToString()!=null)
        { 
            if(hdnfld.Value.ToString()=="Save")
        {
            SaveNewAddress(); 

        }
        else
        {
            UpdateAddress();

        }

如果你真的想在后面的代码中保留一些值，你可以使用隐藏字段而不是viewstate。您可以访问客户端的隐藏字段以及后面的代码。

 <asp:LinkButton ID="lnkAddNewAddress" runat="server" OnClientClick="return CheckType('save');">Click Here To Add New Address</asp:LinkButton>
<asp:HiddenField ID="hdf_type" runat="server" />

Javascript代码

function CheckType(type) {
        document.getElementById("hdf_type").value = type;
         return false;
    }

单击“保存”按钮后访问代码后面的值，并根据隐藏字段中的值执行保存或更新操作。

hdf_type.Value.ToString();

HTML文件应该看起来像

下面我发布的代码对我来说很合适。

<head runat="server">
<title></title>
<script type="text/javascript">
    function CheckType(type) {
        document.getElementById("hdf_type").value = type;
        alert(document.getElementById("hdf_type").value);
        return false;
    }
</script>
 </head>
 <body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<div>


    <asp:LinkButton ID="lnkAddNewAddress" runat="server" OnClientClick="return CheckType('save');">Click Here To Add New Address</asp:LinkButton>

    <asp:Button ID="btn" runat="server" OnClientClick="return CheckType('edit');" Text="Click Here To Add New Address" />

    <asp:ModalPopupExtender ID="lnkAddNewAddress_ModalPopupExtender" runat="server" BackgroundCssClass="modalBackground"
        DynamicServicePath="" Enabled="True" PopupControlID="pnlMyAddressBook" TargetControlID="lnkAddNewAddress"
        ViewStateMode="Enabled">
    </asp:ModalPopupExtender>

    <div id="pnlMyAddressBook" style="height: 100px; width: 100px; display: none; background-color: Gray">
         <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" /><br />

    </div>
    <asp:HiddenField ID="hdf_type" runat="server" />
</div>
</form>

Answer 2

试试这个：

<asp:LinkButton ID="lnkAddNewAddress" runat="server" OnClick="lnkAddNewAddress_Click">Click Here To Add New Address</asp:LinkButton>

<asp:ModalPopupExtender ID="lnkAddNewAddress_ModalPopupExtender" runat="server" BackgroundCssClass="modalBackground"
        DynamicServicePath="" Enabled="True" PopupControlID="pnlMyAddressBook" TargetControlID="btnHidden">
    </asp:ModalPopupExtender>

<asp:Button ID="btnHidden" runat="server" style="Display:none;" Text="Button"/>

在代码背后：

protected void lnkAddNewAddress_Click(object sender, EventArgs e)
    {
        lnkAddNewAddress_ModalPopupExtender.Show();

    }

链接按钮点击不被解雇
