如何强制用户控件中褪色的jquery在单击事件后保持不变?

我有一个基本页面,我要在其中添加一个基于 Bulk Uploader 在c-sharpcorner.com,控件位于jquery fasted div中,基于 yesdegisn

批量上载程序有两个用于两个按钮的服务器端事件处理程序——添加和删除。单击这些按钮后,淡入淡出将消失,您将返回到基本页——如果用户需要添加更多文件,则这是不可取的。添加到列表框的文件数组列表被维护,但我必须单击“淡入”链接(LinkButton id=“lnkDocumentUpload”)才能再次显示此窗口。

我还需要将控件发布到uploadpost.aspx,它也不起作用。单击上载按钮( <asp:Button ID="btnUpload" runat="server" /> )具有上面描述的相同行为——淡入淡出消失,保留数据,不发布。我已经用

<form id="frmUpload" action="~/UploadPost.aspx">
...
    <asp:Button ID="btnUpload" runat="server" Text="Upload"/>
</form>

链接按钮通过激活淡入jquery

$("#lnkDocumentUpload").click(function() {
    centerPopup();
    loadPopup();
});

MyUploader标记:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="MyUploader.ascx.cs" Inherits="Controls.MyUploader" %>
<form id="frmUpload" action="~/UploadPost.aspx">
<table>
    <tr>
        <td style="width: 163px">
            <span style="font-size: 10pt; font-family: Verdana"><strong>
            Select file to upload:</strong></span></td>
        <td style="width: 324px">
            <asp:FileUpload ID="fUpload" runat="server" />&nbsp;<asp:Button ID="btnAdd" runat="server" Text="Add"
              OnClick="btnAdd_Click" /></td>
    </tr>
    <tr>
        <td style="width: 163px">
        </td>
        <td style="width: 324px">
            <asp:ListBox ID="lstFiles" runat="server" Width="324px"></asp:ListBox>
            </td>
    </tr>
    <tr>
        <td style="width: 163px">
        </td>
        <td style="width: 324px">
            <asp:Button ID="btnRemove" runat="server" Text="Remove" OnClick="btnRemove_Click" />
            &nbsp;<asp:Button ID="btnUpload" runat="server" Text="Upload"/></td>
    </tr>
    <tr>
        <td colspan="2">
            <asp:Label ID="lblMessage" runat="server" Font-Names="Verdana" Font-Size="Small"
              ForeColor="Red"></asp:Label></td>
    </tr>
</table> 

MyUploader代码隐藏:

public partial class MyUploader : System.Web.UI.UserControl
{

    protected static ArrayList arrFiles = new ArrayList(); // has to be static since Adding and then reusing

    protected void Page_Load(object sender, EventArgs e)
    {
    }

    protected void btnAdd_Click(object sender, EventArgs e)
    {
        try
        {
            if (Page.IsPostBack)
            {
                arrFiles.Add(fUpload);
                lstFiles.Items.Add(fUpload.PostedFile.FileName);
            }
        }
        catch (Exception ex)
        {
            lblMessage.Text = "An error has occured while adding file" + ex.Message;
        }
    }

    protected void btnRemove_Click(object sender, EventArgs e)
    {
        if (lstFiles.Items.Count != 0)
        {
            arrFiles.Remove(fUpload);
            lstFiles.Items.Remove(lstFiles.SelectedItem.Text);
        }
    }
}
