  • Unusual conversion error (string to integer) asp.net

    - by Phil
    I have my repeater item template: <ItemTemplate> <tr><td><%#Container.DataItem("Category")%></td></tr> </ItemTemplate> Hooked up to: s = "SQL that works ok on server" x = New SqlCommand(s, c) x.Parameters.Add("@contentid", SqlDbType.Int) x.Parameters("@contentid").Value = contentid c.Open() r = x.ExecuteReader If r.HasRows Then Linksrepeater.DataSource = r Linksrepeater.DataBind() End If c.Close() r.Close() When I run the code I get: Invalid Cast Exception was not handled by user code (Conversion from string "category" to type 'Integer' is not valid.) I'm not sure how / why it is trying to convert "Category" to integer as in the db it is a string. Can you please tell me how to avoid this error? thanks.

  • Error messages in ASP.NET with jQuery UI

    - by eugeneK
    I've been using my own Error reporting module which was combination of simple c# and jQueryUI Dialog. Problem is that once error or success occurs i do write it's value to session. It does work pretty good on pages with Responce.Redirect on error but not on pages where i catch an error and then return to same form. My question is why does session which added pre-postback fails to load in pages where i have return statement on some condition. And if there another way to save errors and success message except in session ? Maybe global variables or something like that ...

  • Session State ArrayList in Shopping Cart ASP.NET

    - by user330342
    Hi guys, I'm creating a shopping cart application and I'm having some issues with implementing a session state for my arraylist. in my page load i declared if (Session["Cart"] == null) { Session["Cart"] = new ArrayList(); } else { ArrayList cart = (ArrayList)Session["Cart"]; } to create the session if it doesn't exist yet. then i have an event handler for a button to add items to the arraylist protected void onClick_AddBooking(object sender, EventArgs e) { int ClassID = Convert.ToInt32(Request.QueryString.Get("Class_Id")); ArrayList cart1 = new ArrayList(); cart1 = Session["Cart"]; cart1.Add(ClassID); i'm guessing i just don't know how to handle session states yet, thus the confusion. I'm essentially storing the class_ID then when the student confirms i'll store that to the DB and associate that ID with the Class Details. Thanks in advance guys!

  • ASP.Net databinding in tag

    - by Psytronic
    I know you can bind in the code-behind, but I don't quite understand how it works if you want to declare it within the controls tag. This is for a custom collection. I thought it was just Datasource="<%# MyCollection %" Where MyCollection is an exposed property of the class in the code behind? MyCollection{ get{ return _MyCollection;}} Something like that. But it doesn't seem to work that way, so can I not bind this way, or am I missing something?

  • Multilangual website using ASP and a database

    - by Noam Smadja
    i want to consult about something i do. my website has 3 languages. Hebrew (main), english and russian. i am using a database having a table with the fields: ID, fieldName, 1, 2, 3. where 1 2 3 are the languages. upon entering the website language 1 (hebrew) is chosen automaticly until you choose another. and saved as a session("currentLanguage"). i wrote a function langstirng whice recieves a field name and prints the value acording to the language in session("currentLanguage"): Dim languageStrings Set languageStrings = Server.CreateObject("ADODB.Recordset") languageStrings.ActiveConnection = MM_KerenDB_STRING languageStrings.Source = "SELECT fieldName,"&current_Language&"FROM Multilangual" languageStrings.CursorType = 0 languageStrings.CursorLocation = 2 languageStrings.LockType = 1 languageStrings.Open() sub langstring(fieldName) do while NOT(languageStrings.EOF) if (languageStrings.fields.item("fieldName").value = fieldName) then exit do else languageStrings.movenext end if loop if (languageStrings.EOF) then response.Write("***"&fieldName&"***") else response.Write(languageStrings.fields.item(currentLanguage+1).value) end if languageStrings.movefirst end sub and i use it like so: <div>langstring("header")</div>. i find it stupid that i keep sending the query to the server on any and every page. since the multilangual table does not change "THAT" often i want to somehow save the recordset for the current browsing. I am looking help for THIS solution, Please.

This is the regular expression I have so far: ValidationExpression="(^Anything Entered)$|(^Something Else)$ |(^Another String)$" However when I enter the supposed valid strings the error is displayed. I cant figure out whats wrong with the expression. Any help would be greatly appreciated. Thanks, Zaps

  • Handling Model Inheritance in ASP.NET MVC2

    - by enth
    I've gotten myself stuck on how to handle inheritance in my model when it comes to my controllers/views. Basic Model: public class Procedure : Entity { public Procedure() { } public int Id { get; set; } public DateTime ProcedureDate { get; set; } public ProcedureType Type { get; set; } } public ProcedureA : Procedure { public double VariableA { get; set; } public int VariableB { get; set; } public int Total { get; set; } } public ProcedureB : Procedure { public int Score { get; set; } } etc... many of different procedures eventually. So, I do things like list all the procedures: public class ProcedureController : Controller { public virtual ActionResult List() { IEnumerable<Procedure> procedures = _repository.GetAll(); return View(procedures); } } but now I'm kinda stuck. Basically, from the list page, I need to link to pages where the specific subclass details can be viewed/edited and I'm not sure what the best strategy is. I thought I could add an action on the ProcedureController that would conjure up the right subclass by dynamically figuring out what repository to use and loading the subclass to pass to the view. I had to store the class in the ProcedureType object. I had to create/implement a non-generic IRepository since I can't dynamically cast to a generic one. public virtual ActionResult Details(int procedureID) { Procedure procedure = _repository.GetById(procedureID, false); string className = procedure.Type.Class; Type type = Type.GetType(className, true); Type repositoryType = typeof (IRepository<>).MakeGenericType(type); var repository = (IRepository)DependencyRegistrar.Resolve(repositoryType); Entity procedure = repository.GetById(procedureID, false); return View(procedure); } I haven't even started sorting out how the view is going to determine which partial to load to display the subclass details. I'm wondering if this is a good approach? This makes determining the URL easy. It makes reusing the Procedure display code easy. Another approach is specific controllers for each subclass. It simplifies the controller code, but also means many simple controllers for the many procedure subclasses. Can work out the shared Procedure details with a partial view. How to get to construct the URL to get to the controller/action in the first place? Time to not think about it. Hopefully someone can show me the light. Thanks in advance.

  • ASP.NET MVC 2 Form Not Passing Values

    - by Wayne
    Hi, I have a strange problem happening today. I am running the latest version of the MVC V2 framework and have been having no trouble at all - I came in this morning and for some reason values aren't being passed in to actions. To clarify lets say I have something like this: <% using (Html.BeginForm("Register", "Registration", FormMethod.Post)) { %> .... <input type="submit" name="register" id="register" value="Register" /> <% } %> And in my controller I have the following: [HttpPost] public ActionResult Register(RegistrationModel model, string register) { // At this point the register string is null } This has been working fine for a while now and I have not changed anything that I can think of that would cause this to happen. Does that make sense and as anyone any idea what is going on or what I have messed up? Thanks.

  • Tracking user changes in ASP.NET MVC

    - by Ian Roke
    I have a requirement to track what authenticated users change with regards to the data when logged in. I don't need to track what pages they look at although that could be very useful in future. I have thought about saving the User Guid but that seems very clunky. Are there other methods/best practises?

  • Need Help With ASP.NET Custom Route

    - by Jason
    I need to create a custom route to list all the rooms in a given building. So, I want the url to look something like this: /Building/1000/Room Which would list all the rooms in Building 1000. Is this the correct mapping for the route (to call the IndexByBuilding method in RoomController)? routes.MapRoute( "RoomsByBuilding", "Building/{id}/Room", new { controller = "Room", action = "IndexByBuilding", id = "" } );

  • Saving a modified object from ASP.NET MVC View Using Entity-Franework 4

    - by Dani
    I retrieve an object graph from DB using EF4. The context is closed as soon as the data retrieve and the data passes to the controller, and then to the view. in the view the data is modified, and then the controller gets it back. From the controller I run Repository.Update(MyEmp); and in my repository the code goes: using (var context = new mydb()) { if (myEmp.ID != 0) // Checking if it's modified or new { context.Emp.Attach(MyEmp); int result = context.SaveChanges(); return myEmp.ID; } } The problem - once attached, the object entityState goes to unchanged, and not modified, and of course - nothing is saved to the database. What am I doing wrong ?

  • ASP.NET MVC3 ValueProvider drops string input to a double property

    - by Daniel Koverman
    I'm attempting to validate the input of a text box which corresponds to a property of type double in my model. If the user inputs "foo" I want to know about it so I can display an error. However, the ValueProvider is dropping the value silently (no errors are added to the ModelState). In a normal submission, I fill in "2" for the text box corresponding to myDouble and submit the form. Inspecting controllerContext.HttpContext.Request.Form shows that myDouble=2, among other correct inputs. bindingContext.ValueProvider.GetValue("myDouble") == 2, as expected. The bindingContext.ModelState.Count == 6 and bindingContext.ModelState["myDouble"].Errors.Count == 0. Everything is good and the model binds as expected. Then I fill in "foo" for the text box corresponding to myDouble and submitted the form. Inspecting controllerContext.HttpContext.Request.Form shows that myDouble=foo, which is what I expected. However, bindingContext.ValueProvider.GetValue("myDouble") == null and bindingContext.ModelState.Count == 5 (The exact number isn't important, but it's one less than before). Looking at the ValueProvider, is as if myDouble was never submitted and the model binding occurs as if it wasn't. This makes it difficult to differentiate between a bad input and no input. Is this the expected behavior of ValueProvider? Is there a way to get ValueProvider to report when conversion fails without implementing a custom ValueProvider? Thanks!
