  • Implementing a pager for asp.net's DataList/Repeater

    - by emre
    I have a DataList showing the results, and a Repeater that is supposed to be the pager. I decided to use the page number by redirecting with a QueryString parameter, so it will also be bookmarkable ... My problem is mainly in the UI actually. If I put DIV's with their onclick calling a JS function that does window.location = url + pagenumber , then somehow I have to deal with QueryString operations via JS which is a bit messy. If I use LinkButton objects within the ItemTemplate, then the Redirecting happens only when the linkbutton is clicked while whole div has cursor: pointer , you what I mean. What would be the best approach to this? Thanks in advance. Note: I really want to spend the time and effort implementing my own server-side paging. I think its more fun than reading 3rd party manuals.

  • ASP/VBScript ServerXmlHttp Encoding

    - by colinramsay
    I'm pulling an RSS feed from a remote location using ServerXmlHttp: Dim httpRequest set httpRequest = server.createObject("Msxml2.ServerXMLHTTP.6.0") httpRequest.open "GET", "http://www.someurl.com/feed.xml", false httpRequest.send() response.write httpRequest.responseXML.xml However there must be encoding issues somewhere along the line as I'm seeing ???? where there should be some Japanese characters. Does anyone have any guidance when working with ServerXmlHttp? Thanks.

  • Unit Testing - Validation of ViewModel ASP.NET MVC 2

    - by dean nolan
    I am currently unit testing a service that adds users to a repository. I am using dependency injection to test using a fake repository. The repository has a method CreateUser(User user) which just adds it to the database or in this case a List of Users. The logic for the creation is in the UserServices class. The application has a form for creating a user that requires some properties such as name and address. This is an MVC 2 app and I will be using the new validation using data annotations. This makes me wonder about a few things: 1) Should I annotate a POCO object that will map to the database? Or should I create a specific View Model that has these annotations and pass this data to the UserServices class? 2)Should the UserServicesClass also check this data? Would I best be constructing a Usr out of the ViewModel and passing this into the Service as a parameter? 3) The actual unit testing would depend on 2), I either populate a User object and pass that in, or I pass a large list of strings to the method CreateUser. Writing this out I get a basic idea that I should probably annotate the view model only, pass in a user (constructed by the view model if the data is valid) and also just construct the user in the unit test also. Is this the best way to go?

  • asp.net mvc json result format

    - by ile
    public class JsonCategoriesDisplay { public JsonCategoriesDisplay() { } public int CategoryID { set; get; } public string CategoryTitle { set; get; } } public class ArticleCategoryRepository { private DB db = new DB(); public IQueryable<JsonCategoriesDisplay> JsonFindAllCategories() { var result = from c in db.ArticleCategories select new JsonCategoriesDisplay { CategoryID = c.CategoryID, CategoryTitle = c.Title }; return result; } .... } public class ArticleController : Controller { ArticleRepository articleRepository = new ArticleRepository(); ArticleCategoryRepository articleCategoryRepository = new ArticleCategoryRepository(); public string Categories() { var jsonCats = articleCategoryRepository.JsonFindAllCategories().ToList(); //return Json(jsonCats, JsonRequestBehavior.AllowGet); return new JavaScriptSerializer().Serialize(new { jsonCats}); } } This results with following: {"jsonCats":[{"CategoryID":2,"CategoryTitle":"Politika"},{"CategoryID":3,"CategoryTitle":"Informatika"},{"CategoryID":4,"CategoryTitle":"Nova kategorija"},{"CategoryID":5,"CategoryTitle":"Testna kategorija"}]} If I use line that is commented and place JsonResult instead of returning string, I get following result: [{"CategoryID":2,"CategoryTitle":"Politika"},{"CategoryID":3,"CategoryTitle":"Informatika"},{"CategoryID":4,"CategoryTitle":"Nova kategorija"},{"CategoryID":5,"CategoryTitle":"Testna kategorija"}] But, I need result to be formatted like this: {'2':'Politika','3':'Informatika','4':'Nova kateorija','5':'Testna kategorija'} Is there a simple way to accomplish this or I will need to hardcode result? Thanks in advance!

  • ASP.NET MVC: null reference exception using HtmlHelper.TextBox and custom model binder

    - by mr.nicksta
    I have written a class which implements IModelBinder (see below). This class handles a form which has 3 inputs each representing parts of a date value (day, month, year). I have also written a corresponding HtmlHelper extension method to print out three fields on the form. When the day, month, year inputs are given values which can be parsed, but a seperate value fails validation, all is fine - the fields are repopulated and the page served to the user as expected. however when an invalid values are supplied and a DateTime cannot be parsed, i return an arbitrary DateTime so that the fields will be repopulated when returned to the user. I read up on similar problems people have had and they all seemed to be due to lack of calling SetModelValue(). I wasn't doing this, but even after adding the problem has not been resolved. public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) { string modelName = bindingContext.ModelName; string monthKey = modelName + ".Month"; string dayKey = modelName + ".Day"; string yearKey = modelName + ".Year"; //get values submitted on form string year = bindingContext.ValueProvider[yearKey].AttemptedValue; string month = bindingContext.ValueProvider[monthKey].AttemptedValue; string day = bindingContext.ValueProvider[dayKey].AttemptedValue; DateTime parsedDate; if (DateTime.TryParse(string.Format(DateFormat, year, month, day), out parsedDate)) return parsedDate; //could not parse date time report error, return current date bindingContext.ModelState.AddModelError(yearKey, ValidationErrorMessages.DateInvalid); //added this after reading similar problems, does not fix! bindingContext.ModelState.SetModelValue(modelName, bindingContext.ValueProvider[modelName]); return DateTime.Today; } the null reference exception is thrown when i attempt to create a textbox for the Year property of the date, but strangely not for Day or Month! Can anyone offer an explanation as to why this is? Thanks :-)

  • Accounting Style string format in ASP .NET

    - by Russ Bradberry
    I would like to know the easiest way to format a string as accounting style. I know how to format as currency using {0:c} but there are some differences in accounting style, for example, all the dollar signs will line up as well as all the decimal points, and negatives are expressed in parenthesis rather than with a "-" minus sign. You can find a good example of the way i would like it in excel if you format the cells as "accounting" with 2 decimal places. thanks in advance, russ

  • ASP.Net MVC Object Reference in Edit View when using DropDownListFor()

    - by hermiod
    This question is related to another I ask recently, it can be found here for some background information. Here is the code in the Edit ActionResult: public virtual ActionResult Edit(int id) { ///Set data for DropDownLists. ViewData["MethodList"] = tr.ListMethods(); ViewData["GenderList"] = tr.ListGenders(); ViewData["FocusAreaList"] = tr.ListFocusAreas(); ViewData["SiteList"] = tr.ListSites(); ViewData["TypeList"] = tr.ListTalkbackTypes(); ViewData["CategoryList"] = tr.ListCategories(); return View(tr.GetTalkback(id)); } I add lists to the ViewData to use in the dropdownlists, these are all IEnumerable and are all returning values. GetTalkback() returns an Entity framework object of type Talkback which is generated from the Talkback table. The DropDownListFor code is: <%: Html.DropDownListFor(model=>model.method_id,new SelectList(ViewData["MethodList"] as IEnumerable<SelectListItem>,"Value","Text",Model.method_id)) %> The record I am viewing has values in all fields. When I click submit on the View, I get an Object reference not set to an instance of an object. error on the above line. There are a number of standard fields in the form prior to this, so the error is only occurring on dropdown lists, and it is occurring on all of them. Any ideas? This is my first foray in to MVC, C#, and Entity so I am completely lost!

  • How to add favicon.ico in ASP.NET site

    - by Tapas Bose
    The solution structure of my application is: Now I am in Login.aspx and I am willing to add favicon.ico, placed in the root, in that page. What I am doing is: <link id="Link1" runat="server" rel="shortcut icon" href="../favicon.ico" type="image/x-icon" /> <link id="Link2" runat="server" rel="icon" href="../favicon.ico" type="image/ico" /> Also I have tried: <link id="Link1" runat="server" rel="shortcut icon" href="favicon.ico" type="image/x-icon" /> <link id="Link2" runat="server" rel="icon" href="favicon.ico" type="image/ico" /> But these aren't working. I have cleared the browser cache but no luck. What will be the path to the favicon.ico from: Login.aspx Site.master Thank you. The login page's URL: http://localhost:2873/Pages/Login.aspx and the favicon.ico's URL: http://localhost:2873/favicon.ico. I am unable to see the favicon.ico after changing my code as: <link id="Link1" rel="shortcut icon" href="/favicon.ico" type="image/x-icon" /> <link id="Link2" rel="icon" href="/favicon.ico" type="image/ico" />

  • Add ASP.NET web service while impersonating credentials.

    - by George
    I have a web reference that I do not have access to through my windows credentials, but do through impersonation. Unfortunately, I cannot update or add the reference because of my lack of credentials. When the service is added, it works fine when I set impersonation to true and add credentials. Is there a way to impersonate a credentials when adding/updating a web service reference through the GUI?

  • ASP.NET 2.0: Specifying an instance of an object for an ObjectDataSource

    - by Austin Salonen
    I'm using an ObjectDataSource to bind data to a GridView; it works fine except that it always creates a new object to use as a data source. I can do all the setup just fine but I cannot use an instance of an existing object to specify as the "data source" for it. Is it possible to do this? If so, how? If it's not possible, why? EDIT: Here's the gist of what's going on (object types changed): On the first page you are editting the attributes for a dog. One of the attributes is "has puppies" and if it's true, the next page you specify the names of those puppies. What's happening in my case is that those puppies are not getting linked to the original dog but to a "new" dog. (The implication that my problem is a "female dog" was coincidental. ;-) )

  • Slow Execution of an ASP.NET Web Page

    - by Sweta Jha
    I have a web page which brings 13K+ records in 20 seconds. There is a menu on the page, clicking on which navigates me to another page which is very lightweight. Displaying the data (13K+) took only 20 seconds whereas navigating from that page took much longer, more than 2 mins. Can you tell me why is the latter taking so much of time. I've stopped the page_load code execution on click of the menu. I've disabled the viewstate for that page as well.

  • Aletrnatives to MultiView in ASP.NET

    - by remdao
    Hi The website I'm building contains a large number of views which will be displayed on the same place but hidden or shown according to how the user navigates the menu. It gets quite messy in visual studios design view when you have a MultiView with 10 different views in it. I've already separated the content of each view in several user controls. But is there an alternative to MultiView?

  • ASP.NET MVC unit test controller with HttpContext

    - by user299592
    I am trying to write a unit test for my one controller to verify if a view was returned properly, but this controller has a basecontroller that accesses the HttpContext.Current.Session. Everytime I create a new instance of my controller is calls the basecontroller constructor and the test fails with a null pointer exception on the HttpContext.Current.Session. Here is the code: public class BaseController : Controller { protected BaseController() { ViewData["UserID"] = HttpContext.Current.Session["UserID"]; } } public class IndexController : BaseController { public ActionResult Index() { return View("Index.aspx"); } } [TestMethod] public void Retrieve_IndexTest() { // Arrange const string expectedViewName = "Index"; IndexController controller = new IndexController(); // Act var result = controller.Index() as ViewResult; // Assert Assert.IsNotNull(result, "Should have returned a ViewResult"); Assert.AreEqual(expectedViewName, result.ViewName, "View name should have been {0}", expectedViewName); } Any ideas on how to mock the Session that is accessed in the base controller so the test in the descendant controller will run?

  • Problem retrieving multiple instances of the same asp.net session variable

    - by sw1sh
    I'm having problems with retrieving multiple instances of a session variable from an InProc session state. In the following code I persist a simple BusinessObject into a session variable on the Page_Load event. On the click of a button I try to retrieve the object back into 2 new declared instances of the same BusinessObject. All works great until I change one of the properties in the first instance, it changes the second instance as well. Is this normal behaviour? I would have thought as these were new instances they wouldn’t demonstrate static behaviour? Any ideas where I'm going wrong? Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not Page.IsPostBack Then ' create a new instance of a business object and set a containg variable Dim BO As New BusinessObject BO.SomeVariable = "test" ' persist to inproc session Session("BO") = BO End If End Sub Protected Sub btnRetrieveSessionVariable_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnRetrieveSessionVariable.Click ' retrieve the session variable to a new instance of BusinessObject Dim BO1 As New BusinessObject If Not Session("BO") Is Nothing Then BO1 = Session("BO") ' retrieve the session variable to a new instance of BusinessObject Dim BO2 As New BusinessObject If Not Session("BO") Is Nothing Then BO2 = Session("BO") ' change the property value on the first instance BO1.SomeVariable = "test2" ' why has this changed on both instances? Dim strBO1Property As String = BO1.SomeVariable Dim strBO2Property As String = BO2.SomeVariable End Sub ' simple BusinessObject class Public Class BusinessObject Private _SomeVariable As String Public Property SomeVariable() As String Get Return _SomeVariable End Get Set(ByVal value As String) _SomeVariable = value End Set End Property End Class

  • ASP.NET MVC Model Binding

    - by Noel
    If i have a Controller Action that may recieve both HTTP GET and HTTP POST from a number of different sources with each source sending different data e.g. Source1 performs a form POST with two form items Item1 and Item2 Source2 performs a GET where the data is contained in the query string (?ItemX=2&ItemY=3) Is it possible to have a controller action that will cater for all these cases and perform binding automatically e.g. public ActionResult Test(Dictionary data) { // Do work ... return View(); } Is this possible with a custom binder or some other way? Dont want to work directly with HttpContext.Request if possible
