  • Use textbox value on submit as a query string variable

    - by Eric
    How would I take a text box value and use it in the query string on submit? I'd like it to start as this, /News?favorites=True and end up something like this after the user enters in a search and clicks search. /News?query=test&favorites=True The controller action looks like this public ActionResult Index(string query,bool favorites) { //search code } This question is something close to what I'd like to do, but I'd like to use the query string and maintain the existing values in the query string. Thanks.

  • Fill business object from database by calling stored procedurs?

    - by grady
    Hello, I have several stored procedures in my database, some of them have params, some have no params. I tried to fill a business object by calling the stored procedures, but failed so far. How could I do that dynamically? Later, I want to use this object as a datasource for a report...but thats the next step. The important facts are: different stored procs return different amount of columns stored procs can have params, but its not required How could I achieve that? Thanks :)

  • How important is it for me to pool my connections?

    - by Rio Mango
    It has been suggested to me that I rearrange my code to "pool" my ADO connections. On each web page I would open one connection and keep using the same open connection. But someone else told me that was important 10 years ago but is not so important now. If I make, let's say, 5 db calls on a web posting, is it problematic to be using 5 separate connections that I open/close?

  • How to serialize each item in IEnumerable for ajax post

    - by bflemi3
    I have a PartialView that displays IEnumerable<Movie>. _MoviePartial.cshtml @foreach(var movie in Model) { <div class="content"> <span class="image"><img src="@movie.Posters.Profile" alt="@movie.Title"/></span> <span class="title">@movie.Title</span> <div class="score`"> <span class="critics-score">@movie.Ratings.CriticsScore</span> <span class="audience-score">@movie.Ratings.AudienceScore</span> </div> @Html.ActionLink("Add Movie", "Add", "MyMovies") </div> } When the user clicks the "Add Movie" ActionLink I am going to do an ajax post to add the selected movie to the users collection. My problem is that I would like to send the entire selected Movie class to the "Add" action but not sure how to serialize each movie since the entire Movie class is not rendered in the PartialView, just a few properties. I know I can serialize something like this... <script type="text/javascript"> var obj = @Html.Raw(Json.Encode(movie)); </script> But I'm not sure how that would work inside a foreach loop that renders html, especially inside a PartialView. So, just to be clear, when a user clicks the "Add Movie" ActionLink I would like to send the serialized Movie class for that respective movie to my controller via ajax. My questions is... Is there a better way to serialize each movie and append it to it's respective anchor? I know there's the data- html5 attribute but I thought they only allow string values, not json objects. I also know I could use jQuery's .data() function but I'm struggling to think through how to get that to run from a PartialView, especially since the html rendered by _MoviePartial.cshtml may be returned from a controller via ajax.

  • DateTime Formatting in repeater

    - by Krishna
    Hi, I am trying to format the date time (yyyy/MM/dd) in a repeater which is binded to an ObjectDataSource as shown (THIS WORKS) <%# ((MyType)Container.DataItem).CreateDateTime.ToString("yyyy/MM/dd")% (THIS DOES`NT WORKS) <%# String.Format("{0:yyyy/MM/dd}",((MyType)Container.DataItem).UpdateDateTime)% I want to have both things working because sometimes the property UpdateDateTime is null, in such cases the second line of code handles smart. Thank you for the help in advance.

    - by Blankman
    I want all my views to inherit from a baseview data so I can set some shared properties that all my views will need. Can I set some properties in OnExecuting so I don't have to do it for all Actions? I want to then display the string value of the property in all my view pages. If yes, how can I do this? I need to hook into the base view data somehow? so i'll have: public MyViewData : ViewData { } And I need one for generics also?

  • MVC Helper Extension issue

    - by BeCool
    Hi, I need to implement a HtmlHelper extension in my MVC project simply just to output some string but ONLY in the DEBUG mode, not in REALEASE. My first attempt would be: [Conditional("DEBUG")] public static string TestStringForDebugOnly(this HtmlHelper helper, string testString) { return testString; } But obviously that would give a compile error: "The Conditional attribute is not valid because its return type is not void." So my understanding is once you set [Condition] attribute, it doesnt allow to return anything? why? What is other way to implement this kind of function? anyone help would be much appreciated. Thanks!

  • Specifying a unique control name when adding at runtime (like the VS IDE)

    - by user316383
    hi, I have a basic IDE for a user control i am building. It allows me to add labels to a panel and move them around, like a very basic form designer. When I add the controls to the panel at runtime, I'd like to give the control a unique name string like how the VS IDE tracks the controls it already has and adds an extra number when it creates the default control name. I have tried checking the controls collection each time a new control is added, but wasnt sure if there was a good string comparison method to return a name with a unique number on the end that hasn't been used yet.

  • Gridview inside UpdatePanel refresh

    - by Attilah
    I use a GridView to represent data from a table in my DB. the GridView has some template fields whose content are determined before displaying the Grid ( I use the RowDataBound event to determine content of template fields before displaying the GridView). The page displays a list of records from the table records and then, the recording process starts. after the process is over, the template fields should be updated. how do I automatically refresh the GridView after the process is finished ? it should be noted that the GridView is contained within an control and that I continuously poll the server using a Timer control that executes "GridView1.DataBind()" at the server level every 60 seconds. since the GridView is inside an UpdatePanel, calling DataBind() method on it doesn't seem to call the RowDataBound event. How can I solve this ?

  • Form with list of checkboxes (best practices)

    - by boris callens
    I have a view that allows the user to make a selection from an IEnumerable. The way I'm doing it now is to give each checkbox the id of the item and work with the form collection at the controller's side. I seem to remember there to be a better way but can't remember how anymore. Are there any better practices?

  • MVC Display Template for Generic Type

    - by Kyle
    I am trying to use the model ListModel as a generic list model. I would like to enter on the page @Html.DisplayForModel() However the MVC is not correctly finding the templated file "ListModel.cshtml". It must work differently for generic models. What should I name the templated file in order for it to correctly be located? public class ListModel<T> { public IEnumerable<T> Models {get;set;} public string NextPage {get;set;} } I would expect it to look for "Shared/DisplayTemplates/ListModel.ascx" but it doesn't. Does anyone know?

  • ConcurrenctBag(Of MyType) Vs List(Of MyType)

    - by Ben
    What is the advantage of using a ConcurrentBag(Of MyType) against just using a List(Of MyType)? The MSDN page on the CB (http://msdn.microsoft.com/en-us/library/dd381779(v=VS.100).aspx) states that ConcurrentBag(Of T) is a thread-safe bag implementation, optimized for scenarios where the same thread will be both producing and consuming data stored in the bag So what is the advantage? I can understand the advantage of the other collection types in the Concurrency namespace, but this one puzzled me. Thanks.

  • When should I implement IDisposeable?

    - by Bobby
    What is the best practice for when to implement IDisposeable? Is the best rule of thumb to implement it if you have one managed object in the class, or does it depend if the object was created in the class or just passed in? Should I also do it for classes with no managed objects at all?

  • Session vs singleton pattern

    - by chobo
    Hi, I have a web application where I would like to pull user settings from a database and store them for Global access. Would it make more sense to store the data in a Singleton, or a Session object? What's the difference between the two? Is it better to store the data as an object reference or break it up into value type objects (ints and strings)? Thanks!
