<%# Eval("Description") == DBNull.Value ? "empty" : "notempty"%>
is showing always 'notempty' even there is null in that field in DB (type of varchar(), null)...
Tried also checking for empty string:
<%# Eval("Description") == "" ? "empty" : "notempty"%>
and it always displays notempty... what's wrong here??

I'm putting together a templated, databound control. Presently it works with the following syntax...
<cc:ItemChooserControl ID="ItemChooser" runat="server">
<TitleTemplate>
<h4><%# DataBinder.Eval(Container.DataItem, "DisplayName") %></h4>
</TitleTemplate>
</cc:ItemChooserControl>
Problem
What I would like though is that the shorter, simpler Eval would work instead.
<h4><%# Eval("DisplayName") %></h4>
What I get however when using straight Eval is an error:
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
Code
I'm databinding to a custom HtmlTableCell...
public class TitleTemplateTableCell: HtmlTableCell, INamingContainer
{
private object m_DataItem;
public virtual object DataItem
{
get { return m_DataItem; }
set { m_DataItem = value; }
}
}
With the following custom DataBind (non-related code removed)...
foreach (object dataItem in dataSource) {
TitleTemplateTableCell title = new TitleTemplateTableCell();
TitleTemplate.InstantiateIn(title); // TitleTemplate is the template property
title.DataItem = dataItem;
title.DataBind();
}
i'm trying to make this work for several days but it just doesn't work.
this is my code:
aspx page:

webservice:

this was downloaded from this website.
the problem is that the page loads fine but no autocomplete occurs.
I am a new to WCF. I have written ajax to use a web service before, but on this project I am trying to use ajax to WCF.After I build the project and wcf using ajax, I receive the return successfully. But, 10 or more minutes later I don't get a return, the ajax calls the error function, and the fiddler returns nothing.
If I rebuild the project without any source modifying, I receive the return successfully again.

I am trying to save an updated xml file to a url like this:
Quote:
//save the output to a file
xmlDoc.Save("http://www.example.com/HomeNewsLinks.xml");
But I get this error: URI formats are not supported.
Did some google search on this and it seems I need to use client.uploadFile method, but I am not able to find how to declare/define filenamexxx (below) and how to pass a username/password.
Quote:
WebClient Client = new WebClient();
Client.UploadFile("http://www.example.com/HomeNewsLinks.xml", Post, filenamexxx);

I am following though the examples in Professional ASP.Net MVC 2 and one of the examples doesn't work for me.
[HttpPost]
public ActionResult Edit (int id, FormCollection collection)
{
Dinner dinner = dinnerRepository.GetDinner(id);
if (TryUpdateModel(dinner))
{
dinnerRepository.Save();
return RedirectToAction("Details", new { id = dinner.DinnerID });
}
return View(new DinnerFormViewModel(dinner));
}
I understand that it's suppose to take the values from the FormCollection, and then update the dinner object with it, bit I don't see the collection get referenced anywhere.
I have div which it is hidden by default , when the use clicks show link the following javascript method is called:
function ChangeControlVisibility(elementID) {

I have a listview in which I use a pager control. When I have more than 1 item in the list view, I want the user to be able to click on the appropriate page number and go to it. Simple right?, right now the first time the user clicks on the page number, nothing changes. If they click on it again, it goes right to the page. It doesn't matter what page they click on, it ALWAYS requires a second click to display the data item.
I am using VS2010 C# as the code behind.
I know that UpdateProgress doesn't work with PostBackTrigger, but let me explain what i'm trying:
I'm generating a PDF document (Crystal Report) with ExportToHttpResponse that will be downloaded automaticaly by the browser.
So while the document is been generated, i'd like to show the UpdateProgress just while i'm waiting the doc is being generated, doing the UpdateProgress(or some label) to disappear.
I've been trying to fix something on a secure website (https) which is an Export to Excel button that generates a CSV file. It works on Firefox, Chrome , etc... but not in Internet Explorer. I have changed the headers eliminating the no-cache and also edited the IIS http header configuration setting an expiration date of 1 day. I have no idea of what can be going on and how to solve it. Do you guys have any idea of how to fix this stuff ? I've read so many posts and they're all saying the same thing... caching.
UPDATE 1 :
regarding the error I receive, I receive an IE Alert saying "Internet explorer cannot download filename.aspx from [URL]Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later. As I said, it all works out of SSL (https), but the export to excel button, breaks in https.
UPDATE 2:
I'm using these headers:
Response.ClearContent();
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment; filename=" + name.Trim() + ".csv");
Response.AddHeader("Cache-Control", "no-cache");
Response.AddHeader("Pragma", "public");
Response.AddHeader("Content-Transfer-Encoding", "binary");
Response.AddHeader("Content-Length", "2026");
Response.Charset = "";
//Response.ContentType = "application/vnd.ms-excel";
Response.ContentType = "text/csv";
i've log-in page in my site but log-in control doesn't work on any browser other than IE.
