how to use the xml http object to convert this to ajax. I need to keep this from refreshing everytime I do a postback.
Here is my code
[Code]....
I've scenario where I want to insert data into database without post back. there are around 12 to 13 fields which i need to insert. I'm passing DTO from the client side which is actually Json object. Now the problem which i'm facing is how to convert that Json object which i got in webservice to the "class" (in my case class name is User) object.
[Code]....
In the above case AddNewUser method takes the object of User class. But i'm getting casting error. So how do I convert Json object to the "User" class object?
Is there an easy way to populate my C# Object with the JSON object passed via AJAX?
//This is the JSON Object passed to C# WEBMETHOD from the page using JSON.stringify
{"user":{"name":"asdf","teamname":"b","email":"c","players":["1","2"]}}
//C# WebMetod That receives the JSON Object
[WebMethod]
public static void SaveTeam(Object user)
{
}
//C# Class that represents the object structure of JSON Object passed in to the WebMethod
public class User
{
public string name { get; set; }
public string teamname { get; set; }
public string email { get; set; }
public Array players { get; set; }
}
My question about I created a web site as a file system if I need to publish it what is the rules I follow.

Can someone give me some pointers on how to convert the above to asp.net. I have put two asp:buttons on a webForm. Then for the button clickevent of the btnOn would I use something this like this? Or is WebRequest the wrong concept to use? I can seem to get this code to work for me!

I'm trying to make my website more secured so want to install SSL certificate, for that I've requested a digital certificate from verisign and installed it succesfully in my server(IIS 5.1).
So everything is ready created the virtual directory and now im trying to access my site but now in the url its coming like http:\mysite.com but not https:\mysite.com.
what do we need to do extra other than installing the SSL certificate to convert it form HTTP to HTTPS.
First of all, quickly what exactly I want to achieve: translate particular exception into the HTTP 404 so the ASP.NET can handle it further. I am handling exceptions in the ASP.NET (MVC2) this way:
protected void Application_Error(object sender, EventArgs e) {
var err = Server.GetLastError();
if (err == null)
return;
err = err.GetBaseException();
var noObject = err as ObjectNotFoundException;
if (noObject != null)
HandleObjectNotFound();
var handled = noObject != null;
if (!handled)
Logger.Fatal("Unhandled exception has occured in application.", err);
}
private void HandleObjectNotFound() {
Server.ClearError();
Response.Clear();
// new HttpExcepton(404, "Not Found"); // Throw or not to throw?
Response.StatusCode = 404;
Response.StatusDescription = "Not Found";
Response.StatusDescription = "Not Found";
Response.Write("The whole HTML body explaining whata 404 is??");
}
The problem is that I cannot configure default customErrors to work with it. When it is on then it never redirects to the page specified in customErrors: <error statusCode="404" redirect="404.html"/>. I also tried to raise new HttpExcepton(404, "Not Found") from the handler but then the response code is 200 which I don't understand why. So the questions are:
1-What is the proper way of translating AnException into HTTP 404 response?
2- How does customErrors section work when handling exceptions in Application_Error?
3- Why throwing HttpException(404) renders (blank) page with success (200) status?
In my code below, I'm trying to re-write a string and convert and http text into actual web links.
It doesn't seem to be working and I think the problem may be that I'm rewriting the string and inserting another http string into the original string which then causes problems with the loop.

I have a System.Web.UI.Page page which receive both POST and PUT HTTP requests.
Reading a POST data through the Request.Form field is fine.
But how can i get PUT data? Request.Form field is empty.
Is there a way to access the raw request? or better: The PUT data?
I have two model classes:
public class UserModel
{
public Guid Id { get; set; }
public string EmailAddress { get; set; }
public string LoginName { get; set; }
public string Password { get; set; }
}
public class GroupModel
{
public Guid Id { get; set; }
public string Name { get; set; }
public List<UserModel> Users { get; set; }
}
I created a View (Create.Aspx) by inheriting GroupModel class.
<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<MyApp.Models.GroupModel>" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<body>
<% using (Html.BeginForm()) {%>
<%: Html.ValidationSummary(true) %>
<fieldset>
<legend>Fields</legend>
<div class="editor-label">
<%: Html.LabelFor(model => model.Id) %>
</div>
<div class="editor-field">
<%: Html.TextBoxFor(model => model.Id) %>
<%: Html.ValidationMessageFor(model => model.Id) %>
</div>
<div class="editor-label">
<%: Html.LabelFor(model => model.Name) %>
</div>
<div class="editor-field">
<%: Html.TextBoxFor(model => model.Name) %>
<%: Html.ValidationMessageFor(model => model.Name) %>
</div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
<% } %>
<div>
<%: Html.ActionLink("Back to List", "Index") %>
</div>
</body>
</html>
It is generating only two fields (Id, Name) in my aspx view. Also I am able to get the form data in the Model class object in ё[HttpPost]ё request which contains the data for ID and NAME field in controller.
[HttpPost]
public ActionResult Create(GroupModel groupModel)
{
try
{
// TODO: Add insert logic here
return RedirectToAction("Index");
}
catch
{
return View();
}
}
How can I get the data in List<UserModel> object? I am thinking to Put a List control with checkboxes containing Users. Then catch them using FormCollection object in controller.

View 3 RepliesHow can i find what are the URL's opened in the browser window and how can i get that page as a page object as described below.

The opened url ='http:\localhostIPTrackingIndex.aspx'
We can fetch the page by giving the below code

How can we do it for all the opened URL's because if we give the HttpContext.Current.CurrentHandler then it will display the page object within the site but i want the page object from other sites also.
I am using C# & mvc and have an aspx view page where I am trying to use inline code to set the style of a div elemnet:
<div id=MyDiv>
<%= MyDiv.Attributes.Add("class", "MyClassStyle") %>
</div>
But when I type the inline code in I get the error
"Cannot implicitly convert type 'void' to 'object'".
Whereas some of the Attrbute methods work fine like
<%= MyDiv.Attributes.Count %>
What is the void it is refering to, is it possible to set the styles like this inline,
