使用Modal

Question

我正在使用asp：Repeater控件在asp.net应用程序中显示已预订的房间。当用户单击“结帐”按钮时，我正在使用Modal来显示信息。现在，我将从Repeater控件复制该信息以在模式的文本框中显示值。

现在，当用户在模式中单击“签出和打印”按钮时，我正在构建QueryString来将bookingId转移到另一个页面以生成Crystal Reports。但是问题是，当我单击按钮时，QueryString返回的是空值，因此下一页将不会生成报告。 有什么可以解决这个问题的吗？

下面是我用于将Repeater控件的DataBound值复制到模式文本框的所有代码：

$(document).on('click', '.chkmodal', function () {
        var bookingid = $(this).closest('section').find('.txtBI1').text();            
        var room_no = $(this).closest('section').find('.room_no').text();
        var cust_name = $(this).closest('section').find('.txtcustname').text();
        var checkin = $(this).closest('section').find('.txtcin1').text();
        var checkout = $(this).closest('section').find('.txtcout2').text();
        var bal = parseFloat($(this).closest('section').find('.txtbal').text());
        var Nod = $(this).closest('section').find('.txtNOD1').text();
        var advance = $(this).closest('section').find('.txtAdvance1').text();
        var extras = $(this).closest('section').find('.txtExtras').text();
        var Total = $(this).closest('section').find('.txtTotalA').text();
        var CGST = $(this).closest('section').find('.txtCGST1').text();
        var Path = $(this).closest('section').find('.txtImgPath').text();
        /*var balanceAmt = parseFloat($('.txtbalance').val());*/
        var pamt = parseFloat($(this).parent().find('.txtPaidAmt').val());
        var res = pamt - bal;

        $('.txtBI1').val(bookingid);
        //$('.bidnor').val(bookingid);
        $('.txtCName').val(room_no);
        $('.custName').val(cust_name);
        $('.txtcin1').val(checkin);
        $('.txtcout2').val(checkout);
        $('.txtbal').val(bal);
        $('.txtNOD1').val(Nod);
        $('.txtAdvance1').val(advance);
        $('.txtExtras').val(extras);
        $('.txtTotalA').val(Total);
        $('.txtCGST1').val(CGST);
        $('.txtPath').attr("src", Path);
        $('.txtPAIDNOW').val(pamt);
        $('.txtGT').val(res);

    });

用于绑定Page_Load事件中的转发器控件的代码：

SqlDataAdapter sda = new SqlDataAdapter("Select * From Booking where status='1'", constring);        
    sda.Fill(dt);
    Repeater1.DataSource = dt;
    Repeater1.DataBind();

用于构建QueryString的代码：

protected void a2_Click3(object sender, EventArgs e)
{
    RepeaterItem item = (sender as LinkButton).NamingContainer as RepeaterItem;
    string BID = ac.Encrypt((item.FindControl("lblRID") as Label).Text);
    bidr = BID.ToString();
}
