  • Dynamicdata Validation Exception Message Caught in JavaScript, not DynamicValidator

    - by Perplexed
    I have a page here with a few list views on it that are all bound to Linq data sources and they seem to be working just fine. I want to add validation such that when a checkbox (IsVoid on the object) is checked, comments must be entered (VoidedComments on the object). Here's the bound object's OnValidate method: partial void OnValidate(ChangeAction action) { if (action == ChangeAction.Update) { if (_IsVoid) { string comments = this.VoidedComments; if (string.IsNullOrEmpty(this._VoidedComments)) { throw new ValidationException("Voided Comments are Required to Void an Error"); } } } } Despite there being a dynamic validator on the page referencing the same ValidationGroup as the dynamic control, when the exception fires, it's caught in JavaScript and the debugger wants to break in. The message is never delivered to the UI as expected. Any thoughts as to What's going on?

  • Combine master-detail databinding

    - by clawson
    I have created data sources from my objects in my project, some of which have other objects as members. When I want to bind a some objects to a data grid I would like to display some of the values from the member objects in the data grid as well but the examples I have come across seem to use an entire other datagrid or controls to display these member object values. How can I combine these values into one data grid? (Preferably without creating a wrapping class) Can I achieve this with LINQ somehow? Your help is greatly appreciated. Thanks P.S. C# or VB examples will do.

  • Global.asax PostAuthenticateRequest binding

    - by Tux
    How can I use the PostAuthenticateRequest event of Global.asax? I'm following this tutorial and it mentions that to use the PostAuthenticateRequest. When I added the Global.asax event it created two files, the markup and the code-behind file. Here is the content of the code-behind file using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Security; using System.Web.SessionState; namespace authentication { public class Global : System.Web.HttpApplication { protected void Application_Start(object sender, EventArgs e) { } protected void Session_Start(object sender, EventArgs e) { } protected void Application_BeginRequest(object sender, EventArgs e) { } protected void Application_AuthenticateRequest(object sender, EventArgs e) { } protected void Application_Error(object sender, EventArgs e) { } protected void Session_End(object sender, EventArgs e) { } protected void Application_End(object sender, EventArgs e) { } } } Now when I type the protected void Application_OnPostAuthenticateRequest(object sender, EventArgs e) It is successfully called. Now I want to know how is the PostAuthenticateRequest binded to this Application_OnPostAuthenticateRequest method?

  • Subsonic 3 - Sequence contains no matching element

    - by bastos.sergio
    I need help creating a LINQ SQL with subsonic. First the basics, this works fine: var query = (from o in bd.concelhos orderby o.descricao select o); var results = query.ToList<concelhos>(); However, I want to filter out some columns and I have created the following code: var query = (from o in bd.concelhos orderby o.descricao select new FilteredConcelhos { id = o.idDistrito + "/" + o.idConcelho, descricao = o.descricao }); var results = query.ToList<FilteredConcelhos>(); which errors out in the ToList method with the description "Sequence contains no matching element" Any help would be great with this...

  • Paging over a lazy-loaded collection with NHibernate

    - by HackedByChinese
    I read this article where Ayende states NHibernate can (compared to EF 4): Collection with lazy=”extra” – Lazy extra means that NHibernate adapts to the operations that you might run on top of your collections. That means that blog.Posts.Count will not force a load of the entire collection, but rather would create a “select count(*) from Posts where BlogId = 1” statement, and that blog.Posts.Contains() will likewise result in a single query rather than paying the price of loading the entire collection to memory. Collection filters and paged collections - this allows you to define additional filters (including paging!) on top of your entities collections, which means that you can easily page through the blog.Posts collection, and not have to load the entire thing into memory. So I decided to put together a test case. I created the cliché Blog model as a simple demonstration, with two classes as follows: public class Blog { public virtual int Id { get; private set; } public virtual string Name { get; set; } public virtual ICollection<Post> Posts { get; private set; } public virtual void AddPost(Post item) { if (Posts == null) Posts = new List<Post>(); if (!Posts.Contains(item)) Posts.Add(item); } } public class Post { public virtual int Id { get; private set; } public virtual string Title { get; set; } public virtual string Body { get; set; } public virtual Blog Blog { get; private set; } } My mappings files look like this: <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" default-access="property" auto-import="true" default-cascade="none" default-lazy="true"> <class xmlns="urn:nhibernate-mapping-2.2" name="Model.Blog, TestEntityFramework, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" table="Blogs"> <id name="Id" type="System.Int32, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="Id" /> <generator class="identity" /> </id> <property name="Name" type="System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="Name" /> </property> <property name="Type" type="System.Int32, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="Type" /> </property> <bag lazy="extra" name="Posts"> <key> <column name="Blog_Id" /> </key> <one-to-many class="Model.Post, TestEntityFramework, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" /> </bag> </class> </hibernate-mapping> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" default-access="property" auto-import="true" default-cascade="none" default-lazy="true"> <class xmlns="urn:nhibernate-mapping-2.2" name="Model.Post, TestEntityFramework, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" table="Posts"> <id name="Id" type="System.Int32, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="Id" /> <generator class="identity" /> </id> <property name="Title" type="System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="Title" /> </property> <property name="Body" type="System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="Body" /> </property> <many-to-one class="Model.Blog, TestEntityFramework, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" name="Blog"> <column name="Blog_id" /> </many-to-one> </class> </hibernate-mapping> My test case looks something like this: using (ISession session = Configuration.Current.CreateSession()) // this class returns a custom ISession that represents either EF4 or NHibernate { blogs = (from b in session.Linq<Blog>() where b.Name.Contains("Test") orderby b.Id select b); Console.WriteLine("# of Blogs containing 'Test': {0}", blogs.Count()); Console.WriteLine("Viewing the first 5 matching Blogs."); foreach (Blog b in blogs.Skip(0).Take(5)) { Console.WriteLine("Blog #{0} \"{1}\" has {2} Posts.", b.Id, b.Name, b.Posts.Count); Console.WriteLine("Viewing first 5 matching Posts."); foreach (Post p in b.Posts.Skip(0).Take(5)) { Console.WriteLine("Post #{0} \"{1}\" \"{2}\"", p.Id, p.Title, p.Body); } } } Using lazy="extra", the call to b.Posts.Count does do a SELECT COUNT(Id)... which is great. However, b.Posts.Skip(0).Take(5) just grabs all Posts for Blog.Id = ?id, and then LINQ on the application side is just taking the first 5 from the resulting collection. What gives?

  • Set Theory and .NET

    - by MasterMax1313
    Recently I came across a situation where set theory and set math fit what I was doing to the letter (granted there was an easier way to accomplish what I needed - i.e. LINQ - but I didn't think of that at the time). However I didn't know of any generic set libraries. Granted IEnumerables provide some set operations (Union, etc.), but nothing like Intersection or set comparison. Can anyone point out something that fits here? Something that implements set math using a generic type?

  • Deploying WPF application: .NET 3.5 issues

    - by Robbert Dam
    Hi all, Users around my country are currently beta-testing our application. My app uses WPF & Linq, so I need .NET 3.5 installation. On most system, everything works find, including automatic installation on .NET 3.5 on machines that do not have that installed yet. However, on one machine (XP SP2) my application does not run. The user reported no issues during .NET 3.5 installation (except for a process that need to close before the installer could continue - he closed the process and continued). The application crashes on startup. To debug this issue, I did the following: Have him reboot his machine Let him manually re-install the .NET 3.5 framework (no errors reported) Have him run a test WPF app that only displays a button - also crashes Let him send the .NET 3.5 installation logs - these are huge, don't now where to look Does anyone have strategy on how to debug such issues? I expect that this will occur more when the application is released..

  • Drawbacks of WebFormsMVP?

    - by Tony_Henrich
    While ASP.NET MVC seems to be a viable technology praised by a lot of developers, I can't seem to find enough reasons to devote my energy and time for it. The main reason is that I don't find enough .NET jobs asking for it. Companies still use WebForms and it works just fine for them. I am not self employed where I get to choose the technology I like. I would rather use my time improve my skills in SilverLight, JQuery, Javascript, SQL, LINQ.. etc. Even Photoshop! So I got interested in webformsmvp.com. I get to still use WebForms and use better testing methods. Anyone who has experience with it can tell me what they didn't like about it?

  • need thoughts on my interview question - .net, c#

    - by uno
    One of the questions I was asked was that I have a database table with following columns pid - unique identifier orderid - varchar(20) documentid - int documentpath - varchar(250) currentLocation - varchar(250) newlocation - varchar(250) status - varchar(15) I have to write a c# app to move the files from currentlocation to newlocation and update status column as either 'SUCCESS' or 'FAILURE'. This was my answer Create a List of all the records using linq Create a command object which would be perform moving files using foreach, invoke a delegate to move the files - use endinvoke to capture any exception and update the db accordingly I was told that command pattern and delegate did not fit the bill here - i was aksed to think and implement a more favorable GoF pattern. Not sure what they were looking for - In this day and age, do candidates keep a lot of info on head as one always has google to find any answer and come up with solution.

  • In what areas might the use of F# be more appropriate than C#?

    - by Peter McGrattan
    Over the last few years F# has evolved into one of Microsoft's fully supported languages employing many ideas incubated in OCaml, ML and Haskell. Over the last several years C# has extended it's general purpose features by introducing more and more functional language features: LINQ (list comprehension), Lamdas, Closures, Anonymous Delegates and more... Given C#'s adoption of these functional features and F#'s taxonomy as an impure functional language (it allows YOU to access framework libraries or change shared state when a function is called if you want to) there is a strong similarity between the two languages although each has it's own polar opposite primary emphasis. I'm interested in any successful models employing these two languages in your production polyglot programs and also the areas within production software (web apps, client apps, server apps) you have written in F# in the past year or so that you would previously have written in C#. EDIT: Edited based on feedback from close votes with the intent of reducing perceived ambiguity.

  • Rx: Piecing together multiple IObservable web requests

    - by McLovin
    Hello, I'm creating multiple asynchronous web requests using IObservables and reactive extensions. So this creates observable for "GET" web request: var tweetObservalue = from request in WebRequestExtensions.CreateWebRequest(outUrl + querystring, method) from response in request.GetResponseAsync() let responseStream = response.GetResponseStream() let reader = new StreamReader(responseStream) select reader.ReadToEnd(); And I can do tweetObservable.Subscribe(response => dosomethingwithresponse(response)); What is the correct way of executing multiple asynchronous web requests with IObservables and LINQ that have to wait until other requests have been finished? For example first I would like to verify user info: create userInfoObservable, then if user info is correct I want to update stats so I get updateStatusObservable then if status is updated I would like create friendshipObservable and so on. Also bonus question, there is a case where I would like to execute web calls simultaneously and when all are finished execute another observable which will until other calls are finished. Thank you.

  • Connecting to SQL Server with Visual Studio Express Editions

    - by tlianza
    I find it odd that in Visual C# 2008 Express edition, when you use the database explorer, your options are: 1) Microsoft Access 2) SQL Server Compact 3.5, and 3) SQL Server Database File. BUT if you use Visual Web Developer 2008 Express, you can connect to a regular SQL Server, Oracle, ODBC, etc. For people developing command-line or other C# apps that need to talk to a SQL Server database, do you really need to build your LINQ/Data Access code with one IDE (Visual Web Developer) and your program in another (Visual C#)? It's not a hard workaround, but it seems weird. If Microsoft wanted to force you to upgrade to Visual Studio to connect to SQL Server, why would they include that feature in one of their free IDEs but not the other? I feel like I might be missing something (like how to do it all in Visual C#). Thanks! Tom

    On Page_Load() in the codebehind, I'd like to enumerate all the <link> tags. The purpose being I want want to add a <link> to a CSS file if it isn't specified in the Page's markup. How can I do this? I'm thinking I should be able to use LINQ on the collection of elements in the header, no? Here's my pseudocode: var pageAlreadyContainsCssLink = false; foreach(var control in this.Header.Controls) { if (control.TagName == "link" && control.Attributes["href"] == "my_css_file.css") { pageAlreadyContainsCssLink = true; break; } } if (pageAlreadyContainsCssLink) { // Don't add <link> element return; } // Add the <link> to the CSS this.AddCssLink(...);

  • Table and Column names causing problems

    - by craig
    I have an issue when the T4 linq templates generate the classes for my MySql db using subsonic 3. It looks like one of our table names "operator" is causing problems in the Context.cs generated class. In the following line of code in Context.cs Visual Studio sees <operator> as a c# operator and generates a compilation error of "Type expected" public Query<operator> operators { get; set; } Is there anyway I can work around this without having to rename my database table and column names? For example hard coding something in Settings.ttinclude to use or map different names to specific db tables and columns?

  • C# Lambda Expression Speed

    - by Nathan
    I have not used many lambda expressions before and I ran into a case where I thought I could make slick use of one. I have a custom list of ~19,000 records and I need to find out if a record exists or not in the list so instead of writing a bunch of loops or using linq to go through the list I decided to try this: for (int i = MinX; i <= MaxX; ++i) { tempY = MinY; while (tempY <= MaxY) { bool exists = myList.Exists(item => item.XCoord == i && item.YCoord == tempY); ++tempY; } } Only problem is it take ~9 - 11 seconds to execute. Am I doing something wrong is this just a case of where I shouldn't be using an expression like this? Thanks.

  • mvc2 validation problem (ambiguous reference between model and models)

    - by ile
    I followed instructions for mvc validation but I can't manage to solve this problem.... This is linq to sql model: I set Entity namespace to be CMS.Model If I try to declare partial class Article in Portal.Models namespace: public partial class Article { .... } Then, after using Article article somewhere in code I get following error: 'Article' is an ambiguous reference between 'Portal.Models.Article' and 'CMS.Model.Article' Portal is project name and CMS is area.... I followed these instructions I aslo created NerdDinner from scratch and in that example validation works. I can't figure out what am I doing wrong... someone noticed my mistake? Is it related with giving name to Entity namespace (in tutorial they used default one) Thanks in advance! PS I'd like to note that I'm c# newbie so I'm not really familiar with these partial classes

  • How to create a custom ADO Multi Dimensional Catalog with no database

    - by Alan Clark
    Does anyone know of an example of how to dynamically define and build ADO MD (ActiveX Data Objects Multidimensional) catalogs and cube definitions with a set of data other than a database? Background: we have a huge amount of data in our application that we export to a database and then query using the usual SQL joins, groups, sums etc to produce reports. The data in the application is originally in objects and arrays. The problem is the amount of data is so large the export can take 2 hours. So I am trying to figure out a good way of querying the objects in memory, either by a custom OLAP algorithm or library, or ADO MD. But I haven't been able to find an example of using ADO MD without a database behind it. We are using Delphi 2010 so would use ADO ActiveX but I imagine the ADO.NET MD is similar. I realize that if the application data was already stored in a database the problem would solve itself. Also if Delphi had LINQ capability I could query the objects and arrays that way.
