  • ASP.NET MVC2 Data Access Layer

    - by Paul
    For a small/medium sized project I'm trying to figure out what is the 'ideal' way to have a domain layer and data access layer. My opinions on coupling tend to be more towards the view that the domain models should not be tightly coupled with the database layer, in other words the data access layer shouldn't actually know anything about the domain objects. I've been looking at Linq-to-sql and it wants to use its own models that it creates, and so it ends up VERY tightly coupled. Whilst I love the way you use linq-to-sql in code I really don't like the way it wants to make its own domain objects. What are some alternatives that I should consider? I tried use NHibernate but I did not like the way I had to use to query and get different objects. I honestly love the syntax and way you use linq, I just don't want it to be so tightly coupled to domain objects.

  • ASP.net custom error page

    - by c11ada
    hey all, im trying to implement a custom error page, what i want to be able to do is have a single generic error page which can display the error which occurred or other information (custom error message). when a error occurs on the website, the user should be directed to this page which shows the error message. so for example if i had a page which was trying to update something to a database, but something went wrong, i should be redirected to the error page which will have some custom text like something like " there has been an error with bla bla bla ... please contact administrator". hope this makes sense thanks

  • ASP.Net UpdatePanel, want to have html-tag as a parameter

    - by Nordis
    This is my problem, I have one textbox, one button and one label. Everything is inside an updatepanel. Let's say I want to test if a valid html-tag is entered in the textbox when I press the button. In the code-behind I have a method for that. Everythings works just fine, except when I actually enter a html-tag in my textbox. If I test < html, it works. But not if I test . So my question is, doesn't the updatepanel accept html-tags as parameters? Because my breakpoint for the button_click doesn't triggers. Sorry for my bad english.. :)

  • C#/.NET: Retrieving the contents/file attributes from a file inside a recycle bin

    - by eibhrum
    Hi, I just wanna ask if there's a possibility to retrieve the contents of a 'dump' file from the recycle bin programatically. The contents that I'm looking for are file attributes like 'Date Last Modified, 'Data created', 'size', etc (without restoring the file itself to the original location to preserve the original attributes found while inside the recycle bin.) Comments and suggestions are highly appreciated. Thanks.

  • Autocomplete jQuery on User Controller within Repeater .NET

    - by TheDPQ
    I have a Multiview search feature on a Web User Controller that is called within a Repeater, OHMY!! I have some training sessions being listed out on a page, each calling an employeeSearch Web User Controller so people can search for employees to add to the training session. I have the Employee Names and Employee IDs listed out in JS on the page and using the jQuery autocomplete i have them search for the employee and populate a hidden field in the User controller. Once the process is done they have the option of adding yet another employee. So i had Autocompelte 'work' in all the employee search boxes, but one i do the initial search (postback) autocomplete won't work again. Then i updated $().ready(function() to pageLoad() so it works correctly on multiple searches but only in the LAST item of the repeater (jQuery is loaded on the User Controller) FYI: I have the JS string set as EMPLOYEENAME|ID and jQuery displays the Employee Name and if they select it throws the ID in a ASP:HIDDEN FIELD <script type="text/javascript"> format_item = function(item, position, length) { var str = item.toString().split("|", 2); return str[0]; } function pageLoad() { $("#<%=tb_EmployeeName.ClientID %>").autocomplete(EmployeeList, { minChars: 0, width: 500, matchContains: true, autoFill: false, scrollHeight: 300, scroll: true, formatItem: format_item, formatMatch: format_item, formatResult: format_item }); $("#<%=tb_EmployeeName.ClientID %>").result(function(event, data, formatted) { var str = data.toString().split("|", 2); $("#<%=hf_EmployeeID.ClientID %>").val(str[1]); }); }; </script> I can already guess that by repeating pageLoad within the User Controll i override the previous pageLoad. THE QUESTION: Is there a way around this, a way to have all the jQuery appear in a single pageLoad or to somehow have a single jquery call to handle all my search boxes? I can't move the jQuery into the page calling all the controllers because i have no way of referencing the specific *tb_EmployeeName* textbox AND *hf_EmployeeID* hidden field. Thank you so much for any help or insight you can give me into this problem. This is the Multiview that on the User Controller <asp:MultiView ID="mv_EmployeeArea" runat="server" ActiveViewIndex="0"> <asp:View ID="vw_Search" runat="server"> <asp:Panel ID="eSearch" runat="server"> <b>Signup Employee Search</b> (<i>Last Name, First Name</i>)<br /> <asp:TextBox ID="tb_EmployeeName" class="EmployeeSearch" runat="server"></asp:TextBox> <asp:HiddenField ID="hf_EmployeeID" runat="server" /> <asp:Button ID="btn_Search" runat="server" Text="Search" /> </asp:Panel> </asp:View> <asp:View ID="vw_Confirm" runat="server"> <b>Signup Confirmation</b> <asp:FormView ID="fv_EmployeeInfo" runat="server"> <ItemTemplate> <%#(Eval("LastName"))%>, <%#(Eval("FirstName"))%><br /> </ItemTemplate> </asp:FormView> <asp:Button ID="btn_Confirm" runat="server" Text="Signup this employee" /> &nbsp; <asp:Button ID="btn_Reset3" runat="server" Text="Reset" /> </asp:View> <asp:View ID="vw_ThankYou" runat="server"> <b>Thank You</b><br /> The employee has been signed up and an email confirmation has been sent out.<br /><br /> <asp:Button ID="btn_Reset" runat="server" Text="Reset" /> </asp:View> </asp:MultiView> UPDATE: I never did find an answer but i had to do a demo so i hacked together something that 'works', but feels sort of cheesy. I am still very much needed of a better question or better understanding.

  • ASP.Net 3.5/4.0 CodeBehind or CodeFile?

    - by Donald Hughes
    I read through the previous post: http://stackoverflow.com/questions/73022/codefile-vs-codebehind, but I'm still confused on which I should use. It sounds like CodeFile is the newer option that should be used, yet VS2010 generates CodeBehind when creating a new Web Form.

    - by Peter
    Hi, I have a bit of code which loads data from a stored procedure in MS SQL Server and then loads the data to a datagridview, which works fine.

  • .NET: IOException for permissions when creating new file?

    - by Rosarch
    I am trying to create a new file and write XML to it: FileStream output = File.Create(Path.Combine(PATH_TO_DATA_DIR, fileName)); The argument evaluates to: C:\path\to\Data\test.xml The exception is: The process cannot access the file 'C:\path\to\Data\test.xml' because it is being used by another process. What am I doing wrong here? UPDATE: This code throws the same exception: StreamWriter writer = new StreamWriter(Path.Combine(PATH_TO_DATA_DIR, fileName)); UPDATE 2: The file I am trying to create does not exist in the file system. So how can be it in use?

  • ASP.NET Timer Event

    - by K Ratnajyothi
    protected void SubmitButtonClicked(object sender, EventArgs e) { System.Timers.Timer timer = new System.Timers.Timer(); --- --- //line 1 get_datasource(); String message = "submitted."; ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "popupAlert", "popupAlert(' " + message + " ');", true); timer.Interval = 30000; timer.Elapsed += new ElapsedEventHandler(timer_tick); // Only raise the event the first time Interval elapses. timer.AutoReset = false; timer.Enabled = true; } } protected void timer_tick(object sender, EventArgs e) { //line 2 get_datasource(); GridView2.DataBind(); } The problem is with the data in the grid view that is being displayed... since when get_datasource which is after line 1 is called the updated data is displayed in the grid view since it is a postback event but when the timer event handler is calling the timer_tick event the get_datasource function is called but after that the updated data is not visible in the grid view. It is nnot getting updated since the timer_tick is not a post back event

  • How to make ASP.Net MVC checkboxes keep state

    - by myotherme
    I have the following situation: I have a class Product that can have a confirmation from various Stations. So I have a ViewModel that holds the Product information, and a list of stations, and all the ProductStationConfirmations. public class ProductViewModel { public Product Product { get; private set; } public List<Station> Stations { get; private set; } public Dictionary<string, ProductStationConfirmation> ProductStationConfirmations { get; private set; } public ProductViewModel(int productID) { // Loads everything from DB } } In my partial view for inserting/editing I iterate over the stations to make a checkbox for each of them: <div class="editor-label"> <%= Html.LabelFor(model => model.Product.Title)%> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Product.Title)%> <%= Html.ValidationMessageFor(model => model.Product.Title)%> </div> <fieldset> <legend>Station Confirmations</legend> <% foreach (var station in Model.Stations) { %> <div class="nexttoeachother"> <div> <%= Html.Encode(station.Name) %> </div> <div> <%= Html.CheckBox("confirm_"+station.ID.ToString(), Request["confirm_"+station.ID.ToString()] == null ? Model.ProductStationConfirmations.ContainsKey(Entities.ProductStationConfirmation.MakeHash(Model.Product.ID, station.ID)) : Request["confirm_" + station.ID.ToString()].Contains("true") ) %> </div> </div> <% } %> </fieldset> This works and I can process the Request values to store the confirmed Stations, but it is really messy. I made it this way to preserve the state of the checkboxes between round trips if there is a problem with the model (missing title, bad value for decimal, or something that can only be checked server-side like duplicate tile). I would expect that there is a nicer way to do this, I just don't know what it is. I suspect that I need to change the shape of my ViewModel to better accommodate the data, but i don't know how. I am using MVC 2.

  • Asp.Net MVC does automatic model validation for DateTime but no others

    - by MattSlay
    I'm using MVC 2 with some Models from a LinqToSql project that I built. I see that when I post back to a Controller Action after editing a form that has a DateTime field from the Model, the MVC Html.ValidationMessageFor() helper will nicely display an error beside the Date text box. This seems to happen automatically when the you test ModelState.IsValid() in the Controller Action, as if the MVC model binding automatically knows that the DateTime field cannot be empty. My question is... I have some other string fields in these LinqToSql generated classes that are Not-Nullable (marked as Not Nullable in Sql Server which passes thourgh to the LinqToSql generated classes), so why doesn't Mr. MVC pick up on those as well and display a "Required" message in the ValidationMessageFor() placeholders I have added for those fields? Sure, I have successfully added the MetadataType(typeof) buddy classes to cover these Non-nullable string fields, but it sure does seem redundant to add all this metadata in buddy classes when the LinqToSql generated classes already contain enough info that MVC could sniff out. It MVC validation works with DateTime automatically, why not these Not-nullable fields too?

  • Asp.net Response.Redirect Error

    - by andrewWinn
    My team and I are working on a portal applicaiton. When a user requests a page, we get a page object (contianing permissions, actual file to use and what not). We then do a Response.Redirect to "~/Default.aspx". The crazy thing is that when the code to validate access and what not is called from a button click event from within an ajax update panel, response.redirect is pasting a "&f2" or a "/" into the url. So rather than http://localhost/Default.aspx, the webbrowser is being redirected to http://localhost/%f2Default.aspx, and is subsequently returning a 404 error. HttpContext.Current.Response.Redirect("~/Default.aspx", false); Anyone have an idea of why this would occur? And it only happens when the click event fires inside an update panel.

    How do you add Javascript file programmatically to the user control? I want the user control to be a complete package - ie I don't want to have to add javascript that's related to the user control on the page where it's used, when I can do it inside the control itself.

The thing is I modified my background & foreground of the menu and so the popoutimage arrow is blended in the background. Is there a way to change the settings of this? And how should I go about? Is there maybe a CSS tag I could use for this? Thx
