How to transfer this code from ASP.NET to ASP.NET MVC to print crystal reports

I have ASP.NET application and some crystal reports and I need to transfer the following code from ASP.NET and use same functionality in MVC , I am using entity framework.
this is the form.aspx code which i send the parameters value to the other form by using hyperlink and NavigateUrl:
<asp:GridView ID="GridView1" Width="100%" CssClass="dynamicTable table table-striped table-bordered table-condensed" style="color:#000000;background-color:#f4eb3c " AutoGenerateColumns="false" runat="server">

IN ASP.NET MVC :
1- I created a webform.aspx.cs and used same code above in MVC project
2- I created the controller code and view
this is the view code :
<div id="hemadiv">
#if (labhema1 != null && labhema1.Report_Date.HasValue)
{
<img width="700" height="200" src="~/Contents/images/aljawdahlogo.png" />
Print Result
<table class="table table-bordered">
<tr>
<td style="text-align:center">
<input type="submit" value="Heamatology Result " onclick="PrintElemhema('#hemadiv')" class="btn btn-primary" />
</td>
</tr>
</table>
<div>
<dl class="horizontal" style="padding:10px">

}
3- this is the controller code :
public ActionResult CashData(int id)
{
var tables = new Orders_Tables
{
testsRanges = db.TestsRanges.ToList(),
LabResults = db.LAB_RESULTS.Where(o => o.ORDER_ID == id)
.Include(p => p.LabTests)
.Include(t => t.Patients).ToList(),
LabParaResult = db.LAB_PARA_RESULTS.Where(o => o.ORDER_ID == id).Include(t => t.Patients).Include(t => t.LabTests).Include(c => c.Customers).ToList(),
LabCultureResults = db.LAB_CULTURE_RESULT.Where(o => o.ORDER_ID == id).Include(t => t.Patients).Include(t => t.LabTests).Include(c => c.Customers).ToList(),
LabMicroResults = db.LAB_MICRO_NEGATIVE_RESULT.Where(o => o.ORDER_ID == id).ToList(),
labCashView = db.LAB_RESULT_CASH_VIEW.Where(o => o.order_number == id).ToList(),
LabParasitologyView = db.LAB_PARASITOLOGY_VIEW.Where(o => o.order_number == id).ToList(),
LabCulturesView = db.LAB_CULTURES_VIEW.Where(o => o.ORDER_ID == id).ToList(),
LabMicroView = db.LAB_MICRO_VIEW.Where(o => o.ORDER_ID == id).ToList(),
LabHistopathologyView = db.LAB_HISTOPATHOLOGY_VIEW.Where(o => o.ORDER_ID == id).ToList(),
LabHistoResult = db.LAB_HISTO_RESULT.Where(o => o.ORDER_ID == id).ToList(),
labtests = db.LabTests.ToList(),
// patients = db.Patients.ToList()
};
4- i created the class LABCASHVIEW
I checked alot of articles in stackoverflow site and one answer just he wrote you can use same design from ASP.NET in ASP.NET MVC
create webform in your MVC project and pass the parameters from MVC to webform then it will work and print crystal reports as same as ASP.NET .
So I did what he said but now I need the final step , How to pass the following parameters from MVC view to webform and print crystal reports :
I need to send the selected order_number , dept_Id , Test_Id and culture parameters from selected row to webform and print crystal report
I used
<a> tag and href="" to
but how to pass all this parameter one time to webform and avoid the error reference object not set to an instance of an object and check if parameters not null first ?
this is the question and answer but no details how to call crystal reports and how to pass multiple parameters to crystal report , for example if i need to print selected order_id or selected invoice :
https://stackoverflow.com/questions/348785/crystal-reports-in-asp-net-mvc
UPDATE :
I gave static values for these textboxes in webform.aspx.cs
and its printing now :
TXTORDERID.Text = "2000000054";
TXTDEPTID.Text = "1";
TXTTESTID.Text = "46";
TXTCULTURE.Text = "2";
now final issue how to send the value for these text boxes in webform from MVC view as the following :
TXTORDERID.Text = Request.QueryString["labCashView.order_number"].ToString();
TXTDEPTID.Text = Request.QueryString["labCashView.DEPTID"].ToString();
TXTTESTID.Text = Request.QueryString["labCashView.Test_Id"].ToString();
TXTCULTURE.Text = Request.QueryString["labCashView.Culture"].ToString();

As I see you completed everything and you need to pass parameters from View to crystal reports try this solution :
Print Result
Then in webform.aspx.cs write the following code and use the value passed from the link :
TXTORDERID.Text = Request.QueryString["order_number"].ToString();
TXTDEPTID.Text = Request.QueryString["deptid"].ToString();
TXTTESTID.Text = Request.QueryString["testid"].ToString();
TXTCULTURE.Text = Request.QueryString["Culture"].ToString();
Hope this will help you and print crystal reports in your MVC view.

How to initialize data for flagged questions and bind it to repeater in c#?

I am working on an Online Exam System. I have stucked in questions (Flagged) these are the questions which are marked by student to be attempted later. I have table named "Questionsflagged" in db. Let's suppose there is a Now I want to initialize data for first question. Here is the code behind button of reviseflagged.
aspx page
Below is the code for repeater.

Sitecore Feed latest 2 items

I have a sitecore web part that I am trying to get to display the top 2 most current items by date. I am having trouble because I am only able to get the latest item to show.
For the ascx Code:
<asp:Repeater ID="newsContainer" runat="server">
<ItemTemplate>
<div class="newsItem">
<h2>News</h2>
<a href="<%# SitecoreUtility.NavigateUrl((Item)Container.DataItem)%>" class="newsHeadline">
<span> <sc:Date ID="Date1" Item="<%# Container.DataItem %>" Field="Posted-Date" Format="MM.dd.yyyy" runat="server" />
<sc:Text ID="Text1" Item="<%# Container.DataItem %>" Field="Title" runat="server" />
</span>
</a>
<!-- <p class="newsSummary">
<asp:Literal ID="litBody" runat="server" Text="<%# SitecoreUtility.TruncateByWords(((Item)Container.DataItem).Fields[Constants.Fields.BODY].Value, 20) %>"></asp:Literal>
...
+ More</p> -->
</div>
</ItemTemplate>
</asp:Repeater>
<asp:Panel ID="pnlPagination" runat="server"></asp:Panel>
<asp:Panel ID="pnlArchive" runat="server">
<!-- <div class="newsArchiveLink">
View Archived News
</div> -->
</asp:Panel>
<asp:Panel ID="pnlCurrent" runat="server">
<div class="newsArchiveLink">
View Current News
</div>
</asp:Panel>
For the ASCX.CS File:
public partial class Homepage_NewsListing : BaseSublayout
{
int CurrentPage = 1;
int PageSize = Constants.Values.SEARCH_SMALL_LIST;
protected void Page_Load(object sender, EventArgs e)
{
CurrentPage = int.Parse(WebUtil.GetQueryString("page", "1"));
List<Item> newsListings = new List<Item>();
Item newsItems = SitecoreUtility.Db.GetItem(Constants.Items.NEWS);
if (WebUtil.GetQueryString("type", "") == "archive")
{
newsListings = newsItems.Children.Where(item =>
(SitecoreUtility.FormatDateAtMidnight(item, Constants.Fields.ARCHIVEDATE) <= DateTime.Now)
&&
(!string.IsNullOrEmpty(item.Fields[Constants.Fields.ARCHIVEDATE].Value))
).OrderBy(item => item.Fields[Constants.Fields.POSTED_DATE].Value).ToList();
pnlArchive.Visible = false;
//pnlCurrent.Visible = true;
pnlCurrent.Visible = false;
}
else
{

newsContainer.DataBind();
}
protected List<Item> DisplayResults(List<Item> results)
{
pnlPagination.Controls.Add(new Pager(results.Count, PageSize, CurrentPage).BuildPaging());
if (CurrentPage > 1)
return results.Skip((CurrentPage - 1) * PageSize).Take(PageSize).ToList();
return results.Take(PageSize).ToList();
}
}

I would first try to make your code a bit more simple (for debugging) and use a fast query to pull items within a date range.
var date = DateTime.Now.AddMonths(3);
var dateString = date.Year.ToString() + date.Month.ToString().PadLeft(2, '0') + date.Day.ToString().PadLeft(2, '0');
var newsList = Sitecore.Context.Database.SelectItems("fast:/sitecore/content/home/your-path-to-news/*[##templatename='Your template name' and #POSTED_DATE > '" + dateString + "']").ToList();
newsList = newsList.OrderByDescending(n => n.Fields["POSTED_DATE"].Value).Take(2).ToList();
newsContainer.DataSource = newsList;
newsContainer.DataBind();

iTextSharp output to PDF

I've been trying to get this working for a long time now and I was hoping that someone could help me out with this. I am trying to save two ListViews from my ASCX control (incorporated to my ASPX page as follows) to a PDF file. I believe that the problem lies in these two lines of code, as I am getting an 'the document has no pages' error when saving. Any ideas would be greatly appreciated! Thanks in advance...

"The Document has no pages" means you haven't actually written anything to the Document before calling document.close().
I suspect that if you set a breakpoint at the line where you call document.add(), you'll never hit it.
I suggest you take a long, hard look at the input and output to HTMLWorker.ParseToList(). I doubt it's what you expect.
