I'm trying to get a very simple client side validation example to work in ASP.NET MVC 2. I'm using data annotations to set a required property "Surname". When I use the Html.ValidationMessageFor(x => x.Surname) the correct client side validation script is written to the page. But when I use Html.ValidationMessage("Surname") the client side validation is not rendered out until after the page has been posted. Client side validation only starts working after a form post! I can see that the script is updated in the page after a form post. There appears to be a bug in Html.ValidationMessage()?

View 4 RepliesAfter upgrading our project to the .net 4.0 framework (from 3.5), we facing some problems with ajax calls with html in the parameters. As soon as the user enters some html in a text area the ajax call isn't executed anymore. If the user enters plain text only, there is no problem.

I have a input of type file and when i try to do a Request.files when the input is wrapped in an update panel...it always returns an empty httpfilecollection. Why???
This is the codebehind: (At HttpContext.Current.Request.Files...its always 0 for the count.)

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 used this,
<a title="Logout" onclick="javascript:document.getElementById('ctl00_ContentPlaceHolder1_LbLogout').click();" href="#" class="logout">Logout</a></li>
<asp:LinkButton ID="LbLogout" runat="server" style="display:none"
onclick="LbLogout_Click">Sign out</asp:LinkButton>
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) {
var element = $("#" + elementID);
if (element.css('display') != 'block' && element.css('display') != 'table') {
element.show();
[code]....
this step works but when i call the previous method at page_load event the method doesn't work:
element.css('display') undefined.
[Code]....
And in default.aspx, the code is
[Code]....
But it is not working, the error is at alert(BiblePeopleArray(0));

Then I tried to retrieve node type from Node this way - Nodes node = Entities.Nodes.First(); string nodetype = node.NodeTypes.Name; but for some reason node.NodeTypes equalls null despite fact that there is some records in NodeTypes table.
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.
