  • ASP.Net - validating email address with regexp?

    - by ElHaix
    When validating an email address with the regex validation component, an additional RequiredFieldValidator must be added to ensure there is a value present. I've mostly taken care of this with a CustomFieldValidator, and taking care of this with Javascript. Is there a better way of doing this?

  • ASP .NET: Cannot call Page WebMethod using jQuery

    - by John
    I created a WebMethod in the code-behind file of my page as such: [System.Web.Services.WebMethod()] public static string Test() { return "TEST"; } I created the following HTML page to test it out: <html> <head> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"/></script> <script type="text/javascript"> function test() { $.ajax({ type: "POST", url: "http://localhost/TestApp/TestPage.aspx/Test", data: "{}", contentType: "application/json; charset=utf-8", dataType: "text", success: function(msg) { alert(msg.d); } }); } </script> </head> <body> <button onclick="test();">Click Me</button> </body> </html> When I click the button, the AJAX fires off, but nothing is returned. When I debug my code, the method Test() doesn't even get called. Any ideas?

  • Have ASP page call save function anytime the user tries to navigate away from page

    - by Breander
    What I have is an input page with a bunch of dynamically created textboxes for the user to input data. The textboxes are dynamically created because the number that are needed are not known until the user selects some options on the page. So what I need to have happen is if the user tries to either A) navigate away from the page or B) select different options bringing up new textboxes. Anything the user may have typed into the textboxes needs to automatically be saved to the database. Like they clicked on the save button on the page. This doesn't sound like a vary smart way to do things or even an easy way to do things but this is the requirement I have been given. No message just save to the database. I have looked into things like onbeforepageunload javascript but that mostly tries to stop the user from navigating away I can't call any code behind code from it. Any help is appreciated. Note : The number of the texboxes with data can be any where between 20 and 500. Yes very crazy but not my idea.

  • Runtime Error in asp.net?(online )

    - by Surya sasidhar
    hi, I develop a web application it is working fine in local. When i upload the site in online through CuteFTP it is showing the error like this... Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off". Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL. please help me i place the but even though it is not working it is giving same error. Thank you

  • ASP.NET MVC partial view and form action name

    - by Dmitriy Shvadskiy
    How do I create a partial view that has a form with assigned id? I got as far as: using (Html.BeginForm(?action?,"Candidate",FormMethod.Post,new {id="blah"})) Partial view is used for both Create and Edit so first parameter ?action? will be different. I can't figure out what value of ?action? supposed to be

  • ASP.net MVC Linq-To-SQL Extended Class Field Binding

    - by user336858
    Hi there, The short version of this question is "Is there a way to get automatic View Object binding for fields defined in a partial class for a Linq-To-SQL generated class?" Apologies if it's been asked before. Example Suppose I have a typical MVC setup with the tables: Posts {PostID, ...} Categories {CategoryID, ...} A post can have more than one category, and a category can identify more than one post. Thus suppose further that I need an extra table: PostCategories {PostID, CategoryID, ...} This handles the many-to-many relationship between posts and categories. As far as I know, there's no way to do this in Linq-to-SQL right now so I have to shoehorn it in by adding a partial Postclass to the project to add that functionality. Something like: public partial class Post { public IEnumerable<Category> Categories{ get { ... } set { ... } } } So here's my question: If a user is accessing my MVC application front-end and begins editing a Post object, they might enter an invalid category. When the server recognizes the invalid input, the usual practice is to return the faulty object to the original view for re-editing along with some error messages. The fields in the edit page are re-populated with the provided values. However I don't know how to get this mechanism to work with the properties I created with the partial class as shown above. Any terminology, links, or tips you can provide would be tremendously helpful!

  • open source custom tooltip (callout) control/code for asp.net

    - by dotnetcoder
    Looking for a custom tooltip (typical yellow baloon callout) on click of an anchor tag. The tooltip should appear and remain in view until the cross button on the tooltip is clicked. Just looking for a tried and tested open source solution. Tried googling this but most of the tooltip [...missing info?...] Ajax control toolkit has the calloutvalidator which seems like a good choice but is tied up to be used for validation tooltips.

  • Pass List of models to controller ASP.NET MVC 5

    - by user3697231
    I have a view where user can enter some data. But problem is this: Let's say you have 3 text box on view. Every time user can fill multiple times this 3 text boxes. To clarify, let's say user fills this 3 text boxes and press button which adds on form again these 3 text boxes. Now when user clicks submit this form is sent to controller, but how do I sent List of models as parameter. My architecture for this problem is something like this: MyModel public int ID { get;set; } public string Something { get; set; } /*This three textboxes can user set multiple times*/ /*Perhaps i Can create new model with these properties and then /*put List of that model as property here, but how to fill that list inside view ??*/ public string TextBoxOneValue { get; set; } public string TextBoxTwoValue { get; set; } public string TextBoxThreeValue { get; set; } Now, i was thinking that i Create PartialView with this 3 text boxes, and then when user clicks button on view another PartialView is loaded. And now, let's say I have Two partial views loaded, and user clicks submit, how that I pass list with values of these 3 text boxes to controller ??

  • Validating primitive types in ASP.NET MVC

    - by Alex
    I've implemented the following classes to validate data public abstract class Validated { public bool IsValid { get { return (GetRuleViolations().Count() == 0); } } public abstract IEnumerable<RuleViolation> GetRuleViolations(); } public partial class User: Validated { public override IEnumerable<RuleViolation> GetRuleViolations() { if (this.Age < 1) yield return new RuleViolation("Age can't be less than 1"); } } It works great! When the form is submitted I just do if (user.IsValid == false) blah... But I still need to validate that the Age is an integer int a = 0; if (!int.TryParse(age, out a)) { error = "Not integer"; // ... } How can I move this to my model?

  • Update database using restful ASP.NET MVC 1.0

    - by Mike
    We are building an MVC 1.0 application right now and using Linq - SQL for our DAL. Following the restful approach we have multiple action events depending on if you are updating or loading or what not. The two that I'm concerned with at this point are the edit and update action methods. Here is the signatures. public ActionResult Update(int customerId, int Id, AggregateModel viewModel) public ActionResult Edit(int customerId, int Id, AggregateModel viewModel) So the idea is that in the Edit method we load up our viewModel and pass it to the view. The user makes changes to the model and then posts back to the Update method. The first thing I could think of to do would be to get the viewModel from the database again, copy the changes in one by one from the posted back model and then submit it back. This would work but does seem clunky to me. What is the best way to insert those changes into the database at this point?

  • ASP.NET MVC 2 Model object validation

    - by Jimmy
    Hey guys, I'm trying to validate a model object outside of the context of ModelState within a controller, I currently have a parser that creates model objects from an excel file and I want to be able to report how many entries were added to the database and how many failed, is there a way to validate a model object on its data annotations outside of model binding? I'm looking for something similar to the rails model method of model.valid? or a way for me to implement that myself. My current solution is just manually checking if a few key fields are present but this duplicates requirements between my model class and its metadata, there has to be a better way to hook into the model validation checking that is done by mvc 2. Thanks

  • resource embedding in asp.net

    - by Mike
    I have a project which needs to generate PDF documents. I am using iTextSharp. I have a pdf which needs to be read and then appended to. To read the pdf document, I'm using PdfReader(), which accepts many forms, but I can't figure out how to reference a pdf in my webapplication to PdfReader. My host does not allow Binary Serialization (apparently that's bad), so I don't think I can load from an embedded resource. I've tried just using PdfReader("report.pdf"), but it keeps throwing an exception telling me that the file isn't found. I've tried putting the file in the bin directory, root directory, in the same directory as the class, but this still doesn't work. It works if I use a fully qualified path to the pdf document, but I can't use that when I upload it to my hosting provider. Does anyone have any suggestions on how I should do this? Thanks

  • Passing contextual info to Views in ASP.NET MVC

    - by Andrey
    I wonder - what is the best way to supply contextual (i.e. not related to any particular view, but to all views at the same time) info to a view (or to master page)? Consider the following scenario. Suppose we have an app that supports multiple UI languages. User can switch them via UI's widgets (something like tabs at the top of the page). Each language is rendered as a separate tab. Tab for the current language should not be rendered. To address these requirements I'm planning to have a javascript piece that will hide current's language tab on the client. To do this, I need current's language tab Id on the client. So, I need some way of passing the Id to master page (for it to be 'fused' into the js script). The best thing I can think of is that all my ViewModels should inherit some ViewModeBase that has a field to hold current language tab Id. Then, whatever View I'm rendering, this Id will always be available for the master page's hiding script. However, I'm concerned that this ViewModelBase can potentially grow in an uncontrolled fashion as number of such pieces of contextual info (like current language) will grow.. Any ideas?
