UML and Patterns: An Introduction to Object-Oriented Analysis and Design and Iterative Development, that follows the UP(Unified Process). It uses a Grasp Controller pattern to interact with domain classes by some methods like NewSale(), AddNewItemToSale() and CloseSale. In windows form, I can instantiate a object of this class in the UI and then use its methods to perform the actions. This works well in Client apps, but when I use asp.net mvc, I cannot find a way to instantiate an object (one for each user) that was always visible for a Controller (MVC). I cannot insert as an attribute inside Controller because it always create a new one.

My question is, is there any benefit to instantiating a new userDetails object in every loop, or can this be created outside the loop and title, forename and surname just written over with every pass of the loop?
I have a Google spreadsheet that I am reading data from and I want to load the data into a list object so I can use but I am having some issues.
Google Spreadsheet

I have create a asp:sitemap on my asp:masterpage. I am then populating the sitemap from an SQL table programmatically. Everything works perfectly except one thing - clicking on the items causes a new window to appear and the selected page opens in that new window. I need the items to open in the existing window. Perhaps sitemapnode - but this gave me some errors. The following is my code.

I'm trying to create a custom control that has a dropdown list and a required field validator in it.I've got as a far as being able to set the error message if the control fails to validate, but I can't actually get it to validate, not can I figure out how to call a .Validate method server side. This is driving me nuts!
To create my control, I followed the article here I ran the text box example through, and I can get that to validate without any problems, so I then went through and created a new set of class files relating to a drop down list.Anyone got any thoughts, or hints as to what might be wrong, or where I should start looking?

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?
I have the following code:

What I'm trying to do is rather basic, but I might have my facts mixed up. I have a details page that has a custom class as it's Model. The custom class uses 2 custom objects with yet another custom object a property of one of the 2. The details page outputs a fair amount of information, but allows the user to post a comment. When the user clicks the post button, the page gets posted to a Details action that looks something like this:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Details(VideoDetailModel vidAndComment) { ....}
[Code]....
The only fields on the form that is posted are CommentText and VideoId. Here is what the VideoDetailModel looks like.
public class VideoDetailModel
{
public VideoDetailModel()
{
[Code]....
I suppose if I added more form fields for the properties I need, they would get posted, but I only need 1 form entry field for the CommentText. If I could get the same Model objects value that were sent to the page to post with the page, it looks like the solution is rather simple. I think using the RenderPartial in the middle of a form is problematic somehow to how the form gets written in html. I can't really put my finger on why things went bonkers, but if I do my RenderPartials before my form and then begin my form with the text entry field and the hidden VideoId, the default ModelBinder works just fine. I was beginning the form, writing the hidden VideoId, rendering several partial views, create my CommentText field, and then closed the form out. The CommentText field would get bound just fine. The hidden VideoId would not. Maybe I missed a rule somewhere about using RenderPartial.
For completeness, the partial view I was rendering took a Comment object and just wrote out it's CommentText data. Several of these objects would exist for a single Video object. All of this data was in a custom type and passed into the View (the main view) as it's Model. This partial view did not have a form and did not have any data entry fields.
I have Create a Custom Principal and a Custom Identiy for my Web Application and upon forms authentication
1 Create a profile of type object
2 Assign it to the Principal profile
3 assign the principal to the Http.Current.User (this now has the complete profile information )
As i understand upon redirection the principal is recreated and i loose the information i had stored in the profile.
I there a way to persist the profile information ?
I though can achieve persisting some information using FormsAuthenticationTicket in userData but that wouldent solve my purpose ..

I have created my custom MembershipProvider. I have used an instance of the class DBConnect within this provider to handle database functions. Please look at the code below:
public class SGIMembershipProvider : MembershipProvider

private string connectionString;
private string applicationName;
private bool enablePasswordReset;

private int passwordAttemptWindow;
private MembershipPasswordFormat passwordFormat;
private int minRequiredNonAlphanumericCharacters;
private int minRequiredPasswordLength;
private string passwordStrengthRegularExpression;
private MachineKeySection machineKey;
**private DBConnect dbConn;**
#endregion
.......
public override bool ChangePassword(string username, string oldPassword, string newPassword)
{
if (!ValidateUser(username, oldPassword))
return false;
ValidatePasswordEventArgs args = new ValidatePasswordEventArgs(username, newPassword, true);
OnValidatingPassword(args);
if (args.Cancel)
{
if (args.FailureInformation != null)
{
throw args.FailureInformation;
}
else
{
throw new Exception("Change password canceled due to new password validation failure.");
}
}
SqlParameter[] p = new SqlParameter[3];
p[0] = new SqlParameter("@applicationName", applicationName);
p[1] = new SqlParameter("@username", username);
p[2] = new SqlParameter("@password", EncodePassword(newPassword));
bool retval = **dbConn.ExecuteSP("User_ChangePassword", p);**
return retval;
} //ChangePassword

{
if (config == null)

}
connectionString = ConnectionStringSettings.ConnectionString;
**dbConn = new DBConnect(connectionString);
dbConn.ConnectToDB();**
......
} //Initialize
......
} // SGIMembershipProvider
I have instantiated dbConn object within Initialize() event. My problem is that how could i dispose off this object when object of SGIMembershipProvider is disposed off. I know the GC will do this all for me, but I need to explicitly dispose off that object. Even I tried to override Finalize() but there is no such overridable method. I have also tried to create destructor for SGIMembershipProvider.
Consider the following data
<xml>
<id>10</id>
<value1>15<value1>
</xml>
I need to use this data as an input to ajax request. For eg. consider a dropdownlist change event, I need to pass these values to the controller.
sample code
//dropdown change event
$("#TestReqID").change(function() {
var id = 10;
var testResults = "abc";
var inXML = "<xml>";
inXML = inXML + "<id>" + id + "</id>";
inXML = inXML + "<value1>" + testResults + "</value1>";
inXML = inXML + "</xml>"
$.getJSON("/Home/UpdateTest/Json/" + inXML, function(data) {
//success code goes here
});
});
in HomeController
public ActionResult UpdateTest(string obj)
{
if (HttpContext.Request.IsAjaxRequest())
{
/*
Need to parse data in "obj" from ajax request
*/
IPTests test = _service.GetIPTest(Convert.ToInt32(id));
return new JsonResult { Data = new { ipTestId = "0", testResults = "" } };
}
return View(test);
}
instead of xml string is it possible to use javascript object like

I am writing a C# MVC5 internet application and am having some trouble getting the 'ApplicationUser' object in a controller that I have created.
Code:
var userManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext()));
ApplicationUser user = userManager.FindByNameAsync(User.Identity.GetUserId()).Result;
When I try to run this code, when a user is logged in, I am getting a null object for the 'ApplicationUser' user.
Is there an easy way to populate my C# Object with the JSON object passed via AJAX?

//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; }
}
I have 2 points for today I. I have a controller in which i have a public static method for getting the details for a checkbox like
[code]....
is it ok for me to use this same function like this one in the view, so that I do not need to use the viewdata object,
<%: Html.DropDownList("country", new SelectList(UserController.GetCountryLists(), "value", "countryname", "0"))%>
Also i have another query, when i use the same id & name for the radiobuttons, validation at the client side is working fine.If I use the same condition for a group of checkboxes, i get do not get the checkboxes highlighted during client validation and only during server validation, i get the error message, but the controls [checkboxes] do not have a red border indicating the error.I have used my own html helper to generate the checkboxlist as per [URL].
I'm a junior ASP.NET developer comes from Java background, so may be my question is strange.
I want to build an ascx (asp control) which accept an object as parameter for example :
1- we have a class called Device ( Contains some properties name, color , Specification (another object))
2- we have a control DeviceItem ( Contains Table to view some of the Device properties value ) and contains a property called Device
if the devices object retrieved from the Database and we have an object called device1 from Type Device
is there a direct way to pass the Device object (device1) to the DeviceItem control, some thing like :
<uc1:DeviceItem ID="DeviceItem1" runat="server" Device="THE_DEVICE_OBJECT"/>
and then bind this object to the controller, to show some properties value?
Is it possible to instantiate an HtmlHelper object in a controller action in order to call HtmlHelper.EditorFor?
I would like to call HtmlHelper.EditorFor to return some partial html generated by an editor template in response to an ajax call. If I can do so I would not need to create an ascx file that otherwise would do the call to EditorFor.
How insert a drop list property into a custom webcontrol? This a drop list property is show all textbox control on usercontrol or webpage.
View 3 RepliesI have a custom control, inherited from Button. This is the class definition for the control and 2 properties:

I show you 2 properties, only to illustrate the problem.
as you see Aplicacion property is of a custom type Sistema, and Roles property is of type List<UserRol>.
The Aplicacion property is rendered well, this way:

The UserRol class is a typical class, without any special attributes.
I have discovered that when I use the custom editor for Roles property, the collection is not persisted. When I use the default editor for the collection, the collection is persisted.
