  • Json problem with Page Method call on IE 8.

    - by ProfK
    I have the following code that populates a select element with values from an ajax call, via a Page Method. In FF, the code works perfectly, in IE8 I get the error: 'ResourceList[...].id' is null or not an object. What can I look at here? function readShift(jsonString) { var shiftInfo = Sys.Serialization.JavaScriptSerializer.deserialize(jsonString); var listItems = ""; listItems += "<option value='0'>[Unassigned]</option>"; for (var i = 0; i < shiftInfo.ResourceList.length; i++) { listItems += "<option value='" + shiftInfo.ResourceList[i].id + "'>" + shiftInfo.ResourceList[i].name + "</option>"; } $("#" + resourceListId).html(listItems); };

  • Integrate ClickOnce update in a setup

    - by Erick
    As recent decision in my team we decided to deploy a software we develop for some time now in ClickOnce. Previously it was deployed with a merge module in a setup project. We had in mind to actually deploy the ClickOnce setup/updater in the web server setup. The problem here would not exactly to integrate it but to make sure to limit the human work to integrate it. Normally I guess it would be necessary to "add - file" and select the folder containing the setup.exe + publish.htm + application files + .application, but I fear that for each time we publish a new version to the hard drive we have to update the setup project as well. Would someone have some insight to help that ? (especially to not have to add the program_[version] folder inside application files that is created each time a new publish is done).

  • MVC Model Binding to a collection where collection does not begin with a 0 index

    - by FloatLeft
    I'm trying to perform remote validation on a property of an item within a collection. The validation works OK on the first item of the collection. The http request to the validation method looks like: /Validation/IsImeiAvailable?ImeiGadgets[0].ImeiNumber=123456789012345 However on the 2nd item where the url looks like below, the validation doesn't work /Validation/IsImeiAvailable?ImeiGadgets[1].ImeiNumber=123456789012345 Now I'm pretty sure the reason for this, is that binding wont work on a collection that doesn't begin with a zero index. My validation method has a signature as below: public JsonResult IsImeiAvailable([Bind(Prefix = "ImeiGadgets")] Models.ViewModels.ImeiGadget[] imeiGadget) Because I'm passing an item within a collection I have to bind like this yet what I'm really passing is just a single value. Is there anyway I can deal with this other than just binding it as a plain old query string. Thanks Edit: This is the quick fix to get the Imei variable but I'd rather use the model binding: string imeiNumber = Request.Url.AbsoluteUri.Substring(Request.Url.AbsoluteUri.IndexOf("=")+1);

  • How to set order of appearance for fields when using Html.EditorFor in MVC 2?

    - by Anrie
    I have the following classes in my Model: public abstract class Entity : IEntity { [ScaffoldColumn(false)] public int Id { get; set; } [Required,StringLength(500)] public string Name { get; set; } } and public class Model : SortableEntity { [Required] public ModelType Type { get; set; } [ListRequired] public List<Producer> Producers { get; set; } public List<PrintArea> PrintAreas { get; set; } public List<Color> Colors { get; set; } } To display the "Model" class in the view I simply call Html.EditorFor(model=model), but the "Name" property of the base class is rendered last, which is not the desired behaviour. Is it possible to influenece on the order of displayed fields somehow?

  • Updating div after full page refresh following AJAX request

    - by TonE
    Hi, I have an AJAX controller action which returns JSON. The returned JSON is handled via jQuery and contains a message displayed in an update div. The JSON also contains a flag which indicates a change in state. If this is true the entire page needs to be reloaded from a different url. This is currently performed in the jQuery using window.location.replace(url). In the situation where a full page refresh occurs, I still want to display the message from the JSON in the update div, but after the page has fully reloaded. How can I ensure the div is updated with the message after the window.location.replace call and the page has been completely reloaded? Thanks. (I realise AJAX is not intended for full page refreshes but I can't think of a simple way of avoiding it in this scenario. Normal behaviour here is updating the div with a status message.)

  • MVC3 View For Loop values initialization

    - by Ryan
    So I have a for loop in my View that is supposed to render out the input boxes. Now inside these input boxes I want to put lables that disappear when you click on them. This is all simple. Now it's probably because my brain was wired for php first, and it has been difficult to get it to think in lambdas and object orientation, but I can't figure out how to do this: @{ for (int i = 0; i < 3; i++) { <div class="editor-label grid_2">User</div> Model.Users[i].UserFirstName = "First Name"; Model.Users[i].UserLastName = "Last Name"; Model.Users[i].UserEmailAddress = "Email Address"; <div class="grid_10"> @Html.TextBoxFor(m => Model.Users[i].UserFirstName, new { @class = "user-input" }) @Html.TextBoxFor(m => Model.Users[i].UserLastName, new { @class = "user-input" }) @Html.TextBoxFor(m => Model.Users[i].UserEmailAddress, new { @class = "user-input-long" }) @Html.CheckBoxFor(m => Model.Users[i].IsUserAdmin) <span>&nbsp;admin?</span> </div> <div class="clear"> </div> } } And initialize the values for the users. And you're probably thinking "Of course that won't work. You're going to get a Null Reference Exception", and you would be correct. I might need to initialize them somewhere else and I don't realize it but I'm just not sure. I've tried the [DefaultValue("First Name")] route and that doesn't work. I'm probably thinking about this wrong, but my brain is already shot from trying to figure out how to wire up these events to the controller, so any help would be appreciated!

  • Convert long number as string in the serialization

    - by Bruno
    I have a custom made class that use a long as ID. However, when I call my action using ajax, my ID is truncated and it loses the last 2 numbers because javascript loses precision when dealing with large numbers. My solution would be to give a string to my javascript, but the ID have to stay as a long on the server side. Is there a way to serialize the property as a string? I'm looking for some kind of attribute. Controller public class CustomersController : ApiController { public IEnumerable<CustomerEntity> Get() { yield return new CustomerEntity() { ID = 1306270928525862486, Name = "Test" }; } } Model public class CustomerEntity { public long ID { get; set; } public string Name { get; set; } } JSON Result [{"Name":"Test","ID":1306270928525862400}]

  • validation controls are not validating on enabling on client side using java script, plz guide

    - by haansi
    Hi, As per requirement I disabled all validation controls in page on PageLoad event in server side. On clicking submit button I want to activate them and validate the page and if the page is ok submit other wise not. I am able to enable all validaters but one thing that I am unable to understand is that they do not validate the page. I set alerts and check they are being enabled but they do not validate the page and let the page submit. I am sorry I couldn't get where I am wrong, may be there need to call some validation method as well or I should prevent default behavior of button. please guide me. Below is my script: <script type="text/javascript"> function NextClicked() { var _ddlStatus = document.getElementById("<%=ddlEmpStatus.ClientID%>"); var _selectedIndex = _ddlStatus.selectedIndex; if (_selectedIndex == 0) { alert("Nothing selected"); }<br/> else<br/> if (_selectedIndex == 1) { for (i = 0; i < Page_Validators.length; i++) { Page_Validators[i].Enabled = true; } } } </script> thanks in anticipation.

  • Access parent class from custom attribute

    - by madcapnmckay
    Hi, Is it possible to access a parent class from within an attribute. For example I would like to create a DropDownListAttribute which can be applied to a property of a viewmodel class in MVC and then create a drop down list from an editor template. I am following a similar line as Kazi Manzur Rashid here. He adds the collection of categories into viewdata and retrieves them using the key supplied to the attribute. I would like to do something like the below, public ExampleDropDownViewModel { public IEnumerable<SelectListItem> Categories {get;set;} [DropDownList("Categories")] public int CategoryID { get;set; } } The attribute takes the name of the property containing the collection to bind to. I can't figure out how to access a property on the parent class of the attribute. Does anyone know how to do this? Thanks

  • Which is more flexible in regards to database changes, EF 4 or Linq to SQL

    - by JBeckton
    Reading about both Linq to SQL and Entity Framework I have developed the impression that EF is more suitable for apps that get data from multiple data sources. But as I am reading about MVC2 models I see an example where EF is more loosely coupled with your data model. If I have to add or remove some columns from a table then what is involved in updating my model or DAL with each of these implementations?

  • JQuery modal box form validation

    - by vikitor
    Hi, I was using a view to create an object for my specific project, but now I have to adapt this to another requirements, such as the creation of this object must be integrated in the creation of another one. The thing is, that this object must be created before starting to create the other one, and the way of doing it will be poping up a modal dialog box with JQuery with the form to create it. I've got to adapt the creation and it works fine, except for the validation messages. It is made in the controller like : if (not.NotName.Trim().Length == 0) { ModelState.AddModelError("NotName", "Name is required"); } if (_notification.checkIfExists(not.NotName, not.NotRecID)) { ModelState.AddModelError("NotName", "Notification already exists"); } And before with a normal view it worked fine, but now I'm not able to get the validation messages as I did. How can you get this validation messages thrown by the controller in the Modal Box? Because now when I made a mistake on purpose in the form in order to get the error it doesn't appear. I've seen the error is displayed in the site, because I've seen it on firebug, but it doesn't appear in my model box. How can I retrieve this errors? Do you know any tutorial that could help me with this? Thank you

  • I need to convert the result of a stored procedure in a dbml file to IQueryable to view a list in an

    - by RJ
    I have a MVC project that has a Linq to SQL dbml class. It is a table called Clients that houses client information. I can easily get the information to display in a View using the code I followed in Nerd Dinner but I have added a stored procedure to the dbml and it's result set is of IQueryable, not IQueryable. I need to convert IQueryable to IQueryable so I can display it in the same View. The reason for the sproc is so I can pass a search string tothe sproc and return the same information as a full list but filtered on the search. I know I can use Linq to filter the whole list but I don't want the whole list so I am using the sproc. Here is the code in my ClientRepository with a comment where I need to convert. What code goes in the commented spot. public IQueryable<Client> SelectClientsBySearch(String search) { IQueryable<SelectClientsBySearchResult> spClientList = (from p in db.SelectClientsBySearch(search) select p).AsQueryable(); //what is the code to convert IQueryable<SelectClientsBySearchResult> to IQueryable<Client> return clientList; }

  • How to get the id of Updatepanel which initiated a postback

    - by Voice
    Hi I need to intercept server callback after udate panel async post back and determine which panel initiated the request. The code is pretty simple: Sys.WebForms.PageRequestManager.getInstance().add_pageLoaded(InterceptUpdateCallback); function InterceptUpdateCallback(sender, args) { var updatedPanels = args.get_panelsUpdated(); for (idx = 0; idx < updatedPanels.length; idx++) { if (updatedPanels[idx].id == "myUpdatePanel") { StartSmth(); break; } } } And it works when UpdatePanel is not inside another UpdatePanel. But when it is inside another UpdatePanel updatedPanels[idx].id has parent Updatepanel id. So how can I get the id of UpdatePanel which initiated the request (the inner UpdatePanel)? Thanx

  • LINQ to SQL for tables across databases. Or View?

    - by BritishDeveloper
    I have a Message table and a User table. Both are in separate databases. There is a userID in the Message table that is used to join to the User table to find things like userName. How can I create this in LINQ to SQL? I can't seem to do a cross database join. Should I create a View in the database and use that instead? Will that work? What will happen to CRUD against it? E.g. if I delete a message - surely it won't delete the user? I'd imagine it would throw an error. What to do? I can't move the tables into the same database!

  • Extension method not working if I set controller property in Action, works in OnExecuting

    - by Blankman
    I have a class MyController that inherits from Controller, so all my controllers inherit from MyController. I have a property in MyController: public class MyController : Controller { public string SomeProperty {get;set;} } if I set this property in MyController's OnExecuting method, my HtmlHelper extension method works fine: public static string SomeExtension(this HtmlHelper htmlHelper) { StringBuilder sb = new StringBuilder(); string result = ""; var controller = htmlHelper.ViewContext.Controller as MyController; if (controller != null) { result = controller.SomeProperty; } return result; } it doesn't work if I set 'SomeProperty' in my controllers action method. I guess because I am doing 'as MyController' in the extension method? is there a way for it to work in both situations? I am using the value of SomeProperty to be outputted on my view pages.

  • varchar data type to datetime data type resulted in an out-of-range??

    - by leen3o
    Very weird problem occurred, I have moved a site from one server to another - All is working, but any query involving a date is playing up. I get the following: DELETE FROM MYTABLE WHERE categoryId = -2 AND datecreated < '3/23/2010'; The conversion of a varchar data type to a datetime data type resulted in an out-of-range value Now what's strange is I have changed the LCID to 1033 on the new server as the date is showing as US format and its still throwing an error! I then tried 2057 and again the same error? Made no difference. I'm a little confused, as this is a working site from a server with IIS6 - The locale is 1033 on that server and it works perfectly!! :S I have just tried thrown a Cdate() around the date too and yet again the same error??? Any ideas??

  • MVC Forms Authentication with custom database

    - by AndrewVos
    I'm trying to get forms authentication working for an mvc site. I have a custom database with a users table, and I would like to do my own password validation. I am logging in my user like this: if (PasswordHasher.Hash(password) == dataUser.Password) { FormsAuthentication.SetAuthCookie(email, true); return true; } The problem is, when the session expires obviously the user has to login again. I am thinking I should be storing this Auth cookie in my users table? Update: I'm obviously in desperate need of more education in this area. I just noticed that the user stays authenticated even after an iisreset. I guess what I'm asking is how can I get persistent and non persistent authentication working properly. I want a user to not have to login again if they click "remember", and if they don't then their authentication should expire when the forms authentication is set to expire.
