  • Is there a way to prevent an ASP.Net webapp from clearing out page variables on VB side?

    - by Chapso
    I have a webapp in ASP.Net with a VB codebehind. I need a List variable I have declared to persist as long as the person is on the page, but currently any time a control posts back to the code, everything is cleared out. I am completely new to ASP.net, so I have no idea if this is even possible. Can it be done with a Session variable? Those seem to me to be limited to base types, but I could be wrong.

  • How can I check for missing references in VB.NET?

    - by Tea With Cookies
    I need to check if all the references in a project exist to avoid possible errors but I can't find anywhere how to do it in VB.NET. I can do it in VBA like this: Dim vbProj As VBProject Dim chkRef As Reference Set vbProj = ThisWorkbook.VBProject For Each chkRef In vbProj.References If chkRef.IsBroken Then Debug.Print chkRef.Name " reference doesn't exist!" End If Next How do I accomplish this in VB.NET?

  • How can I tell if a <script> tag with a given src attribute is present on the page in ASP.net?

    - by Chris McCall
    Like the title says, I'm trying to find out if I need to include a script library that my ASP.net UserControl needs to work. I don't want to include it multiple times per page, but I want my control to be able to be used multiple times on the same page. How can I, in the codebehind of my control, check to see if a given <script/> tag is present? This is .Net 2.0, no LINQ.

  • Can a Java portlet be embedded in an ASP.NET page?

    - by frankadelic
    We have some portlets created by a team working on a JEE site. They would like to include one of these portlets within a site I manage, which is ASP.NET. Aside from solutions like iframes, is it possible to embed a Java portlet within an ASP.NET page? (Note: I don't have much Java/portlet experience, so please take that into consideration in your answer) UPDATE Is this relevant to my question? http://download.oracle.com/docs/cd/E13174_01/alui/devdoc/docs60/Portlets/Basics/Hello_World_Portlet_NET.htm

  • ASP.NET MVC 3 Client-Side Validation Summary with jQuery Validation (Unobtrusive JavaScript)

    - by Soe Tun
    When we were working with ASP.NET MVC 2, we needed to write our own JavaScript to get Client-Side Validation Summary with jQuery Validation plugin. I am one of those unfortunate people still stuck with .NET Framework Runtime 2.0 and .NET Framework 3.5; meaning I am still on ASP.NET MVC 2. So I will still keep on supporting by answering any question you may have with my original code.   Long awaited ASP.NET MVC 3 has been released, and it supports Client Side Validation Summary with jQuery out-of-the-box with new features like Unobtrusive JavaScript.   1. _Layout.cshtml Template Notice that I am using Protocol Relative URLs ( i.e., '//'.  Not 'http://' or 'https://' ) to reference script files and css files and you should use it too like that! However, please note that IE7 and IE8 will download the CSS files twice so use it with judgement. <!DOCTYPE html> <html> <head> <title>@ViewBag.Title</title> <link href="@Url.Content("~/Assets/Site.css")" rel="stylesheet" type="text/css" /> <link href="//ajax.googleapis.com/ajax/libs/jqueryui/1.8.9/themes/redmond/jquery-ui.css" rel="stylesheet" type="text/css" media="screen" /> </head> <body> @RenderBody() <script src="//ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js" type="text/javascript"></script> <script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.8.9/jquery-ui.min.js" type="text/javascript"></script> <script src="//ajax.microsoft.com/ajax/jQuery.Validate/1.7/jQuery.Validate.min.js" type="text/javascript"></script> <script src="//ajax.aspnetcdn.com/ajax/mvc/3.0/jquery.validate.unobtrusive.min.js" type="text/javascript"></script> </body> </html>   2. MVC View Template There are 3 things you *must* do exactly to get Client Side Validation Summary working. (1)  You must declare your Validation Summary **inside** the `Html.BeginForm()` block like below. (2)  You must pass `excludePropertyErrors: false` to the  Html.ValidationSummary()  method. @using (Html.BeginForm()) { @Html.ValidationSummary(false, "Please fix these errors."); <!-- The rest of your View Template --> }   (3)  You have to put the following two elements in the `<appSettings />` block of your Web.config file. <add key="ClientValidationEnabled" value="true"/> <add key="UnobtrusiveJavaScriptEnabled" value="true"/>   That is all you need to do.  Simple, right? I will upload a sample project for download soon.  Please let me know if you run into some issues.     P.S: Without getting into too much technical details, I just wanted to let you know what I went through to get this to work. I had to look into the ASP.NET MVC 3 RTM Source Code and the jquery.validate.unobtrusive.js source. Initially, I thought I have to hack the jquery.validate.unobtrusive.js or something to get this to work. But after digging into MVC3 RTM source, I found out how to do it.

  • How to handle lookup data in a C# ASP.Net MVC4 application?

    - by Jim
    I am writing an MVC4 application to track documents we have on file for our clients. I'm using code first, and have created models for my objects (Company, Document, etc...). I am now faced with the topic of document expiration. Business logic dictates certain documents will expire a set number of days past the document date. For example, Document A might expire in 180 days, Document 2 in 365 days, etc... I have a class for my documents as shown below (simplified for this example). What is the best way for me to create a lookup for expiration values? I want to specify documents of type DocumentA expire in 30 days, type DocumentB expire in 75 days, etc... I can think of a few ways to do this: Lookup table in the database I can query New property in my class (DaysValidFor) which has a custom getter that returns different values based on the DocumentType A method that takes in the document type and returns the number of days and I'm sure there are other ways I'm not even thinking of. My main concern is a) not violating any best practices and b) maintainability. Are there any pros/cons I need to be aware of for the above options, or is this a case of "just pick one and run with it"? One last thought, right now the number of days is a value that does not need to be stored anywhere on a per-document basis -- however, it is possible that business logic will change this (i.e., DocumentA's are 30 days expiration by default, but this DocumentA associated with Company XYZ will be 60 days because we like them). In that case, is a property in the Document class the best way to go, seeing as I need to add that field to the DB? namespace Models { // Types of documents to track public enum DocumentType { DocumentA, DocumentB, DocumentC // etc... } // Document model public class Document { public int DocumentID { get; set; } // Foreign key to companies public int CompanyID { get; set; } public DocumentType DocumentType { get; set; } // Helper to translate enum's value to an integer for DB storage [Column("DocumentType")] public int DocumentTypeInt { get { return (int)this.DocumentType; } set { this.DocumentType = (DocumentType)value; } } [DataType(DataType.Date)] [DisplayFormat(DataFormatString = "{0:MM-dd-yyyy}", ApplyFormatInEditMode = true)] public DateTime DocumentDate { get; set; } // Navigation properties public virtual Company Company { get; set; } } }

  • Does ModSecurity 2.7.1 work with ASP.NET MVC 3?

    - by autonomatt
    I'm trying to get ModSecurity 2.7.1 to work with an ASP.NET MVC 3 website. The installation ran without errors and looking at the event log, ModSecurity is starting up successfully. I am using the modsecurity.conf-recommended file to set the basic rules. The problem I'm having is that whenever I am POSTing some form data, it doesn't get through to the controller action (or model binder). I have SecRuleEngine set to DetectionOnly. I have SecRequestBodyAccess set to On. With these settings, the body of the POST never reaches the controller action. If I set SecRequestBodyAccess to Off it works, so it's definitely something to do with how ModSecurity forwards the body data. The ModSecurity debug shows the following (looks to me as if all passed through): Second phase starting (dcfg 94b750). Input filter: Reading request body. Adding request argument (BODY): name "[0].IsSelected", value "on" Adding request argument (BODY): name "[0].Quantity", value "1" Adding request argument (BODY): name "[0].VariantSku", value "047861" Adding request argument (BODY): name "[1].Quantity", value "0" Adding request argument (BODY): name "[1].VariantSku", value "047862" Input filter: Completed receiving request body (length 115).

Hook insert_filter: Adding input forwarding filter (r 5541fc0). Hook insert_filter: Adding output filter (r 5541fc0). Initialising logging. Starting phase LOGGING. Recording persistent data took 0 microseconds. Audit log: Ignoring a non-relevant request. I can't see anything unusual in Fiddler. I'm using a ViewModel in the parameters of my action. No data is bound if SecRequestBodyAccess is set to On. I'm even logging all the Request.Form.Keys and values via log4net, but not getting any values there either. I'm starting to wonder if ModSecurity actually works with ASP.NET MVC or if there is some conflict with the ModSecurity http Module and the model binder kicking in. Does anyone have any suggestions or can anyone confirm they have ModSecurity working with an ASP.NET MVC website?

  • How to build a good service layer in ASP.NET?

    - by Swippen
    I have looked through some questions, technologies for building a good service layer but I have some questions regarding this that I need help with. First some information of what I have for requirements. We currently have a number of web applications that talk to each other in a spiderweb looking way (all talking to each other in a confusing way via webservices and database data). We want to change this so that all applications go through a service layer where we can work more with cache and encapsulate common functionality and more. We want this layer to also have a Web API so that 3rd party clients can consume information from the service. The problem I see is that if we build the service layer with say MVC4 Web API don't we need to communicate between the application using the webAPI meaning we have to construct URLs and consume JSON/Xml. That does not sound too effective. I assume a better method would be working with entities and WCF to communicate between the application but then we might loose the Web API magic? So the question is if there is a way to consume a service layer as both a Web API (JSON/XML) and as a more backend service layer with entities. If we are forced to use 2 different service layers we might have to duplicate some functionality and other bad things. Hope the question is clear enough and please ask if you need any more information.
