  • Common programming mistakes in .Net when handling exceptions?

    - by Jared Coleson
    What are some of the most common mistakes you've seen made when handling exceptions? It seems like exception handling can be one of the hardest things to learn how to do "right" in .Net. Especially considering the currently #1 ranked answer to Common programming mistakes for .NET developers to avoid? is related to exception handling. Hopefully by listing some of the most common mistakes we can all learn to handle exceptions better.

    - by Midhat
    Hi I have a large index, on which Highlighter.Net works fine, but FastVectorHighlighter returns null as a Best Fragment on Some documents. the searcher works fine. It is just the highlighter.

  • How to make per- http Request cache in ASP.NET 3.5

    - by Artem
    We using ASP.NET 3.5 (Controls-based apporach) and need to have storage specific for one http request only. Thread-specific cache with keys from session id won't work because threads are supposed to be pooled and therefore I have a chance to have data from some previous request in cache, which is undesireble in my case. I always need to have brand new storage for each request available through whole request. Any ideas how to do it in ASP.NET 3.5?

  • New to ASP.NET: Webforms vs MVC2

    - by Sahat
    I am new to ASP.NET Development and can't decide between developing with Webforms or MVC 2. Nevermind the pros and cons of each. I've seen mixed opinions of each. But which method would be the best for someone who has no prior experience in ASP.NET or C#? If your answer is: learn both, then which should I learn first? MVC 2 or Webforms?

  • ASP.NET MVC 2 - user defined database connection.

    - by J Harley
    Hello, I am looking to port my very basic DBMS software from classic ASP to ASP.net - however the user would need to input the connection details in order to connect to their specific DBMS server.

  • ASP.NET sets of technologies/components

    - by Maxim Gueivandov
    Just a question of pure curiosity. It happens that development teams tend to stick to the same technological set(s) for some time, for various reasons (obviously, the lack of time, money, necessity and/or willingless to adopt new technologies). So, what are your usual sets of technologies/components to build an ASP.NET application (e.g., WebForms / MVC, Automapper, NInject, NHibernate / LinqToSql, JQuery / ASP.NET Ajax, ...) or architectural frameworks (Arch#, Catharsis, ...) and in which context do you use them (site size, speed/availability requirements, etc.)?

  • How can I access attributes of Html elements in ASP.NET MVC

    - by Richard77
    With ASP.NET Webforms, I could drag and drop a control on a form and be able to access its properties: if (number == 0) AddButton.Enabled = false; Although I cannot drag and drop a control on a ASP.NET MVC View template, can I change its attributes? For instance: disable a button in some conditions and be able to enable it if conditions change. Be able to change the text of a button from "Next-" to "Finish" etc.

  • ASP.NET MVC 2 - Setting id of Html.Form

    - by Justin
    Hey, How do you set the id of an Html.Form in ASP.NET MVC 2? I tried this: <% using (Html.BeginForm("Save", "Clients", new { id = "SubmitForm" })) {%> But it doesn't work, my form still doesn't have an id property: <form action="/TothSolutions/Secure/Clients/Save/SubmitForm" method="post"> I'm guessing this worked in ASP.NET MVC 1 but not 2. The reason I need the id property set is so that I can do jQuery validation on the form: $("#myForm").validate etc... Thanks, Justin

  • ASP.NET web control with the same ID

    - by user370401
    On an ASP.NET page, if the ASP.NET elements like <asp:Texbox ID="Textbox1"> appears in more than one place, are they the same Textbox object or are they different objects with the same name "Textbox1"? If the same, "why won't it cause any conflicts?" E.G. runat="server" Text='<%# Bind("Name") %' runat="server" Text='<%# Bind("Name") %' '

  • Generating an Excel file in ASP.NET

    - by Dan Coates
    I am about to add a section to an ASP.NET app (VB.NET codebehind) that will allow a user to get data returned to them as an Excel file, which I will generate based on database data. While there are several ways of doing this, each has its own drawbacks. How would you return the data? I'm looking for something that's as clean and straightforward as possible.
