  • How to display some data differnetly than it is stored.

    - by Ben
    Hello, I seem to have a problem that I can't find a solution for. I have a table that has this format. projectId | departmentId | plan | ETC | month | year | ID But, I need to find a way to take that data and display it like this. Since this is my first time here I can't upload an image, but you can view it here. http://img85.imageshack.us/img85/8253/image004y.png Is this something a gridview can handle, or a repeater, or something else? Thank you. Ben

  • Limit the model data fields serialized by Web API based on the return type Interface

    - by Stevo3000
    We're updating our architecture to use a single object model for desktop, web and mobile that can be used in the MVVM pattern. I would like to be able to limit the data fields that are serialized through Web API by using interfaces on the controllers. This is required because the model objects for mobile are stored in HTML5 local storage so don't carry optional data while a thin desktop client would be able to store (and work with) more data. To achieve this a model will implement the different interfaces that define which data fields should be serialized and there will be a controller specific to the interface. The problem is that the Web API always serializes every field in the model even if it is not part of the interface being returned. How can we only serialize fields in the returned interface?

  • C# delegate or Func for 'all methods'?

    - by Michel
    Hi, i've read something about Func's and delegates and that they can help you to pass a method as a parameter. Now i have a cachingservice, and it has this declaration: public static void AddToCache<T>(T model, double millisecs, string cacheId) where T : class public static T GetFromCache<T>(string cacheId) where T : class So in a place where i want to cache some data, i check if it exists in the cache (with GetFromCache) and if not, get the data from somewhere, and the add it to the cache (with AddToCache) Now i want to extend the AddToCache method with a parameter, which is the class+method to call to get the data Then the declaration would be like this public static void AddToCache<T>(T model, double millisecs, string cacheId, Func/Delegate methode) where T : class Then this method could check wether the cache has data or not, and if not, get the data itself via the method it got provided. Then in the calling code i could say: AddToCache<Person>(p, 10000, "Person", new PersonService().GetPersonById(1)); AddToCache<Advert>(a, 100000, "Advert", new AdvertService().GetAdverts(3)); What i want to achieve is that the 'if cache is empty get data and add to cache' logic is placed on only one place. I hope this makes sense :) Oh, by the way, the question is: is this possible?

  • Web Deployment Projects tool and Web application project

    - by SourceC
    Hello, Q1 - As far as I know, Visual Studio doesn’t use aspnet_compiler.exe when compiling web application projects. And since Web Deployment Projects (WDP) tool is only used for manipulation the output created by aspnet_compiler.exe, I don’t understand how VS 2008 also has an option for using WDP with web application projects?! Q2 - What is a stock project? thanx EDIT: So I was right about the fact that Visual Studio doesn’t use aspnet_compiler.exe when compiling web application projects? much appreciated

  • Problem with LINQ in C#

    - by David Bonnici
    I am encountering a problem when using LINQ in C#, I am constantly getting "Specified cast is not valid". This is what I am trying to do. I create a class in which I declare all the columns of the table. [Table(Name="tbl_Aff")] public class Affiliate { [Column] public string name; [Column] public string firstname; [Column] public string surname; [Column] public string title; } I then declare a strongly typed DataContext in which I declare all Table collections as members of the context. public partial class Database : DataContext { public Table affiliate; public Database() : base(Settings.getConnectionString()) { } //This method gets the connection string by reading from an XML file. } public partial class Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Database database = new Database(); try { var q = from a in database.affiliate select a; foreach (var aff in q) // Here I get the error "Specified cast is not valid" { lblMessage.InnerHtml += aff.name + ""; } } catch (Exception ex) { System.Console.WriteLine(ex.Message); } } }

  • Set .aspx page title to that of an Eval

    - by user1860529
    I am trying to use an <%# Eval("name") %> to be the title of my page. I can't seem to figure out any solutions online. I have tried the other StackOverflow question but that did now work either. The page is a bio.aspx and on the site it is displayed as bio.aspx?id=123 so the page title needs to vary depending on the ID. I figured I could just use the Eval("name") but no luck yet. I currently am using JavaScript: window.onload = function() { document.title = '<%# Eval("name") %> | Title Line'; } This works, but it still leaves the title tags empty, and it's kind of spammy. Here is the codebehind: using System; using System.Data; using System.Configuration; using System.Collections; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; public partial class DoctorBio : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Page.Title = "Your Page Title"; HtmlMeta metaDescription = new HtmlMeta(); metaDescription.Name = "description"; metaDescription.Content = "brief description"; Page.Header.Controls.Add(metaDescription); HtmlMeta metaKeywords = new HtmlMeta(); metaKeywords.Name = "keywords"; metaKeywords.Content = "keywords, keywords"; Page.Header.Controls.Add(metaKeywords); } protected void SetPageTitle(object title) { this.Title = title.ToString(); } protected string ReplaceLineBreaks(object text) { string newText = text as string; if (newText == null) { return string.Empty; } return newText.Replace("\r\n", "<br />"); } }

  • Onclick not firing

    - by user320588
    I have a set of buttons on my master page (I have attached the code below) but no onclick event is being raised. I pulled the final page source and no onclick event was present. As you can see I tried a few different approaches to solve the problem. I am looking for a normal postback to the server but I am getting nothing when I click any of these buttons. What am I not doing? --Master --Master Code Behind Protected Sub Button_Command(ByVal sender As Object, ByVal e As CommandEventArgs) Handles btnCancel.Command, btnClear.Command Session("ButtonClicked") = e.CommandArgument End Sub Protected Sub Button_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnSave.Click, btnSubmit.Click Session("ButtonClicked") = CType(sender, Button).CommandArgument End Sub --Page Source

  • When to use MVC Scaffolding via NuGet vs MVC Scaffolding via MVC3 Tools Update

    - by James
    I am a little confused about the various different "mainstream" scaffolding options for MVC3. There is a NuGet package called MVCScaffolding. It first showed up in Jan 2011, but seems to be active and have recent updates, and be developed by Scott Hanselman, among others. Then in May 2011 came the MVC3 Tools Update. This seems like it incorporated the original scaffolding ideas into an "out of the box" scaffolding options. However, this has not been updated since. So - what is the relationship between these two scaffoldings (if any). Are there cases when one should be used over the other, or is it just a matter of taste? Does Visual Studio 2012 or MVC4 change the game on any of this? Thanks for any input.

  • Managing EntityConnection lifetime

    - by kervin
    There have been many question on managing EntityContext lifetime, e.g. http://stackoverflow.com/questions/813457/instantiating-a-context-in-linq-to-entities I've come to the conclusion that the entity context should be considered a unit-of-work and therefore not reused. Great. But while doing some research for speeding up my database access, I ran into this blog post... Improving Entity Framework Performance The post argues that EFs poor performance compared to other frameworks is often due to the EntityConnection object being created each time a new EntityContext object is needed. To test this I manually created a static EntityConnection in Global.asax.cs Application_Start(). I then converted all my context using statements to using( MyObjContext currContext = new MyObjeContext(globalStaticEFConnection) { .... } This seems to have sped things up a bit without any errors so far as far as I can tell. But is this safe? Does using a applicationwide static EntityConnection introduce race conditions? Best regards, Kervin

  • How to make a Generic Repository?

    - by chobo2
    Hi I am wondering if anyone has any good tutorials(or maybe even a library that is already made and well documented) on making a generic repository. I am using currently linq to sql but it might change so I don't know if you can make a generic repository that would take little to no changes if I would say switch to entity framework. Thanks

  • Allowing non-admin users to unstick the print spooler

    - by Reafidy
    I currently have an issue where the print que is getting stuck on a central print server (windows server 2008). Using the "Clear all documents" function does not clear it and gets stuck too. I need non-admin users to be able to clear the print cue from there work stations. I have tried using the following winforms program which I created and allows a user to stop the print spooler, delete printer files in the "C:\Windows\System32\spool\PRINTERS folder" and then start the print spooler but this functionality requires the program to be runs as an administrator, how can I allow my normal users to execute this program without giving them admin privileges? Or is there another way I can allow normal user to clear the print que on the server? Imports System.ServiceProcess Public Class Form1 Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click ClearJammedPrinter() End Sub Public Sub ClearJammedPrinter() Dim tspTimeOut As TimeSpan = New TimeSpan(0, 0, 5) Dim controllerStatus As ServiceControllerStatus = ServiceController1.Status Try If ServiceController1.Status <> ServiceProcess.ServiceControllerStatus.Stopped Then ServiceController1.Stop() End If Try ServiceController1.WaitForStatus(ServiceProcess.ServiceControllerStatus.Stopped, tspTimeOut) Catch Throw New Exception("The controller could not be stopped") End Try Dim strSpoolerFolder As String = "C:\Windows\System32\spool\PRINTERS" Dim s As String For Each s In System.IO.Directory.GetFiles(strSpoolerFolder) System.IO.File.Delete(s) Next s Catch ex As Exception MsgBox(ex.Message) Finally Try Select Case controllerStatus Case ServiceControllerStatus.Running If ServiceController1.Status <> ServiceControllerStatus.Running Then ServiceController1.Start() Case ServiceControllerStatus.Stopped If ServiceController1.Status <> ServiceControllerStatus.Stopped Then ServiceController1.Stop() End Select ServiceController1.WaitForStatus(controllerStatus, tspTimeOut) Catch MsgBox(String.Format("{0}{1}", "The print spooler service could not be returned to its original setting and is currently: ", ServiceController1.Status)) End Try End Try End Sub End Class
