Can it handle mapping using private members like NHibernate can? The documentation is very slim, but it seems like one of the objects or methods provided with the tool could do something like this.
I have like 10 private members in my class, and I was hoping vs.net could create public properties from them but can't seem to find that option in VS.NET 2008.
Since we can access the private data member of base class in the derived class with the help of friend function. How can we do the same in C# asp.net? I mean whats the alternative of friend function in C# asp.net
Our site has a page for maintenance of existing members (e.g. adding / changing roles, etc.)This page currently uses a gridview to show a complete list of all members, based on GetMembers() method to populate it.However, as the number of users has grown to several hundred, it has become difficult to locate a particular user by paging through several pages.Is there a way to narrow down this list, maybe with a filtering textbox, so that as you start typing into that textbox, only members whose name contains the typed characters will show up in the gridview?
This may be a little more up the alley of our mvc fellows, but regardless.
First, I have the following model:
Csharp Code:
[code]....
Notes: RenderPartials is a custom extension method and that part works, as do the actual views. The correct data is displayed. Just not in the expected order. In fact, it mirrors the database.
I'm trying to figure out the best approach to architecting this project. Basically, it's a "band" profile site. I'm using ASP.NET 4, EF, and Automapper (structuremap too, but that's not important). I'm running into performance issues I have a EntityFramework repository class that interacts directly onto the EF objects using LINQ:
[Pluggable("Repository")] public class EntityDataRepository : IRepository static EntityDataRepository() // other mappings removed // Data. objects are EF objects, mapping to my DTO classes [code]...
Is it possible with automapper in C# to map the properties of an object to an array/dictionary? I have tried the following:
Mapper.CreateMap<FFCLeads.Models.FFCLead, Dictionary<string, SqlParameter>>() .ForMember(d => d["LeadID"], o => o.MapFrom(s => new SqlParameter("LeadID", s.LeadID))) .ForMember(d => d["LastName"], o => o.MapFrom(s => new SqlParameter("LastName", s.LastName)));
However, it does not work (object ref not set to an instance). Basically, I'm trying to make the values of this object to an array of SqlParameter objects. Possible? If so, what is the correct way to do this?
Currently im using EF and using its datacontext directly in all of my actions, but since i started reading about loose coupling and testability im thinking that thats not the best way to go. Im trying to understand all the pro's and con's before i start refactor all my current code.
Problem 1:
Considering that every entity needs its own repository, and thus has to setup its own connection to a datasource (lets assume a database using EF), wouldnt that give alot of overhead if i need data from 5 different entities on a single page?
Problem 2:
What im seeing aswell in all the examples which i found online is that most people (even people like shanselman) implement the repository pattern using the entity classes which are generated by either LINQ or EF, doesn't this defeat the purpose of repository pattern with regards to loose coupling? On the other hand, what is the alternative, using POCO classes in combination with for example AutoMapper? (this scares me a little) Im hoping that a few people can shed some light on this, because im a bit confused at the moment if the repository pattern is the right choice for a website.
I was wondering if it is possible to map multiple DTO objects to a single ViewModel object using Automapper?
Essentially, I have multiple DTO objects and would like to display information from each on a single screen in ASP.NET MVC 2.0. To do so I would like to flatten the DTO objects (or parts of them...) into the Viewmodel and pass said viewmodel to the view. If I had one DTO this would be easy, but I've never seen it being done with multiple. Obviously there are a number of roundabout ways to do this (outside of automapper), but this is the approach that I would like to take if possible.
This is pretty much the same error I got when trying to use the entity object directly as model, rather than having AutoMapper create a ViewModel. So what am I doing wrong? This is driving me crazy...
UPDATE 3:Well, neverending story... I found some info on using UseDestinationValue on the CreateMap method in AutoMapper. So I tried that, and well, that actually got me a bit further. But...now I get a new exception on SaveChanges() (in the EF model). The exception now is: "The operation failed: The relationship could not be changed because one or more of the foreign-key properties is non-nullable." This appears to be an exception that also occurs when trying to delete child objects in a one-to-many relationship if you don't have cascade delete set, but that's not what I'm trying to do here...
Here's the updated CreateMap methods:Mapper.CreateMap<ConsultantViewModel, Consultant>().ForMember("Id", opts => opts.Ignore()).ForMember( x => x.Programs, opts => opts.UseDestinationValue()); Mapper.CreateMap<Consultant, ConsultantViewModel>();
I want to assign Guid to UserId of my UserDTO if UserId is Null. Is it possible to do this in the CreateMap or creating any formatter?. I am using automapper as an attribute on my Actions in controller.
I am using AUtomapper which I am very impressed with however, I have a complex object with many nested collections. I'm using Telerik OpenAccess and it returns the 1400 records fast but when I pass it to Automapper and it slows to a ridiculous crawl. Here is my code for reference:
public class ComponentType { public int ComponentTypeID { get; set; } public string Component_Type { get; set; } public string ComponentDesc { get; set; } } [code]...
if a class has a private constructor then it cant be instantiated. so, if i dont want my class to be instantiated and still use it, then i can make it static. what is the use of a private constructor? Also its used in singleton class, except that, is there any othe use ? (Note : The reason i am excuding the singleton case above is because I dont understand why do we need a singleton at all ? when there is a static class availble.
I have admin and member role, now i wan to do like, in the admin page, i wan to display all members only in a gridview Im using the default provider and database How should i do that?
I ask if i can use static variables in my web application, what are the alternatives to (static)? when i use static variable in specific page and more than one user use the application , it make conflict data(incorrect data).what are the limits of static members using?are static members are shared in memory?
I have an web application that encrypts data using a public and sent it to another web application. Which will then decrypt the data using a the user private key. My question is, since but the Private and Public key are generated in the first application. how does the other application get the private?
private void Form1_Load(System.Object sender, System.EventArgs e) { Dim stri As String stri ="SELECT allowType fROM SLABS order by allowtype" this.FillCombo(stri, Cmballowa); } private void FillCombo(string ssql, object cbo) { SqlDataAdapter da = default(SqlDataAdapter); SqlConnection con = new SqlConnection(); DataSet ds = null; DataView dv = null; con = new SqlConnection(constr); da = new SqlDataAdapter(ssql, con); ds = new DataSet(); da.Fill(ds, "ITEM"); dv = ds.Tables("ITEM").DefaultView; cbo.DataSource = dv; }
But here some error message is coming in "private FillCombo function" like "'object' does not contain a definition for 'DataSource' and no extension method 'DataSource' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?)" So, how can i correct this error?
f i send email to first member, everything is ok ,, but next member will have 2 email .. email for him and the message for first one !and i have another problem with ( send to all ) All members received the Message , But without the subject and textthis a contol page .aspx code
What is the best way to set up a members only section where users can edit their personal information, save profile images, view friends, view images, etc...? Would it be best to create a site map for just the members only section? when changing pages within the members only section is the userid passed in a querystring or something separate?
I am building a ASP.NET website that has members pages. I have created a folder where I keep the members pages in and that can only be accessed by logging in or creating a new account. The problem is how do I make the url of these members pages secure, so that someone cant simply give the url to another user for them to copy into a browser or bookmark.
I have searched for an answer to my problem and could not find an answer anywhere.
I am rebuilding a website (converting it to use masterpages, usercontrols, asp.net memberships, etc using asp.net 4.0 C#) that has two different types of users. The problem is, the two different users have different roles ie. customers and employeers. Depending on the role the user is assigned to they will have different things that should be stored in their profile.
For instance a customer would have all the basic elements of a profile, name, address, phone, etc. But it would also have some extra stuff like, a little bit about themselves, their resume, where they went to school, etc. On the other hand an employer would have the basic elements but it would include details such as the position, a description of the position, contact for that position, etc.
Is there any way to have multiple profiles and still use the asp.net sql membership and profile provider?
My environment is .Net2.0, VS 2008, Web Application
I need to lock a record when two members are trying to access at the same time.
We can do it in two ways,
By Front end (putting the sessionID and record unique number in the dictionary and keeping it as a static or application variable), we will release when the response is go out of that page, client is not connected, after the post button is clicked and session is out. By backend (record locking in the DB itself - need to study - my team member is looking ).
Is there any others to ways to do and do I need to look at other ways in each and every steps?
