  • Handling button click in ASP.NET MVC 2 RTM

    - by Leniel Macaferi
    I have a View in which the user is able to upload a file to the server. In this view I also have 2 buttons: one to Upload a file and other to Download the last file imported. In my Controller I created 2 action methods: Import and Export. How could I manage to redirect each button click to the proper action method in my Controller? I have tried Html.ActionLink: <%= Html.ActionLink("Upload", "Import", "OracleFile")%> <%= Html.ActionLink("Download", "Export", "OracleFile")%> Html.ActionLink didn't do the trick. The action links were taking me to the right Action methods but they were generating a GET request. This way Request.Files.Count = 0. I need a POST request.

  • Clean Web.Config file in Asp.NET 4.0?

    - by Braveyard
    Okay, I am wondering having clear web.config file could be good but you know some shared web hosting companies don't allow us to touch things like machine.config and etc. So If a lot of things have been moved onto machine.config, then will we be allowed to change things like we used to through web.config file.

  • Multiple Headers in asp.net

    - by digiguru
    I'm running code that seems to hit the "AppendHeader" twice in the code. Response.Filter = New DeflateStream(Response.Filter, CompressionMode.Compress, True) Response.AppendHeader("Content-encoding", "deflate") ... Response.AppendHeader("Content-encoding", "deflate") I have tried using the following.... Response.Headers("Content-encoding") = "deflate" But it says This operation requires IIS integrated pipeline mode. How do I check for a headers existence, and overwrite it rather than appending it.

    Is it possible to display a static line across a chart which appears at a given point on the Y Axis? So say I have a chart which measures test scores, ranges which 0 to 100 which 70% being the pass mark and therefore displaying a straight line across the chart at this point? Would I have to add a new series or is there a property for such a function? Thanks, Damien

  • How to register assemblies using Windsor in ASP.NET MVC

    - by oz
    This is how my project looks: TestMvc (my web project) has a reference to the DomainModel.Core assembly where my interfaces and business objects reside. The class that implements the interfaces in DomainModel.Core is in a different assembly called DomainModel.SqlRepository; the reason behind it is that if I just want to create a repository for Oracle I just have to deploy the new dll, change the web.config and be done with it. When I build the solution, if I look at the \bin folder of my TestMvc project, there is no reference to the DomainModel.SqlRepository, which makes sense because it's not being reference anywhere. Problem arises when my windsor controller factory tries to resolve that assembly, since it's not on the \bin directory. So is there a way to point windsor to a specific location, without adding a reference to that assembly? My web.config looks like this: <component id="UserService" service="TestMvc.DomainModel.Core.Interface, TestMvc.DomainModel.Core" type="TestMvc.DomainModel.SqlRepository.Class, TestMvc.DomainModel.SqlRepository" lifestyle="PerWebRequest" /> There's many ways around this, like copying the dll as part of the build, add the reference to the project so it will get copied to the \bin folder or install it on the GAC and add an assembly reference in the web.config. I guess my question is specific to Windsor, to see if I can give the location of my assembly and it will resolve it.

  • Using embedded standard HTML forms with ASP.NET

    - by RM
    I have a standard aspx page with which I need to add another standard HTML form into and have it submit to another location (external site), however whenever I press the submit button the page seems to do a post back rather than using the sub-forms action url. A mock up of what the form relationships is below. Note in the real deployment the form will be part of a content area of a master page layout, so the form needs to submit independantly from the master page form. <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title>Untitled Page</title> </head> <body> <form id="form1" runat="server"> <div> <form id="subscribe_form" method="post" action="https://someothersite.com" name="em_subscribe_form" > <input type="text" id="field1" name="field1" /> <input id="submitsubform" type="submit" value="Submit" /> </form> </div> </form> </body> </html>

  • Does "Debug" invalidate ASP.Net MVC OutputCache?

    - by William Edmondson
    I have images stored in a database and am serving them from an MVC controller as "FileResult". If I run the MVC application from Visual Studio 2008 in debug mode and set a break point inside the controller method the debugger intercepts the call on every page refresh regardless of my "OutputCache" settings. Does the VS debugger invalidate the OutputCache or is there something else going on here? [OutputCache(Duration = 86400, VaryByParam = "id")] public FileResult Index(string id) { byte[] image; int imageId; int.TryParse(id, out imageId); using (var ctx = new EPEntities()) { var imageObj = (from images in ctx.Images where images.ID == imageId select images).FirstOrDefault(); image = imageObj.Image; } return new FileContentResult(image, "image/gif"); }

  • ASP.NET - dynamically creating database connection in datasets

    - by Foo
    I am currently using datasets for my data access layer. I currently store the connection string in the web.config file. I need the ability to change the connection to another database before any queries are processed. Is there an event that is triggered or a base class that can be modified that intercepts the process of retrieving the connection string from the web.config file? Is there any way to handle multiple database connections using the same code base and also take advantage of the connection pooling? I understand the best method is to get rid of datasets and use custom data objects. Any ideas?

  • Common DataAnnotations in ASP.Net MVC2

    - by Scott Mayfield
    Howdy, I have what should be a simple question. I have a set of validations that use System.CompontentModel.DataAnnotations . I have some validations that are specific to certain view models, so I'm comfortable with having the validation code in the same file as my models (as in the default AccountModels.cs file that ships with MVC2). But I have some common validations that apply to several models as well (valid email address format for example). When I cut/paste that validation to the second model that needs it, of course I get a duplicate definition error because they're in the same namespace (projectName.Models). So I thought of removing the common validations to a separate class within the namespace, expecting that all of my view models would be able to access the validations from there. Unexpectedly, the validations are no longer accessible. I've verified that they are still in the same namespace, and they are all public. I wouldn't expect that I would have to have any specific reference to them (tried adding using statement for the same namespace, but that didn't resolve it, and via the add references dialog, a project can't reference itself (makes sense). So any idea why public validations that have simply been moved to another file in the same namespace aren't visible to my models? CommonValidations.cs using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.ComponentModel; using System.ComponentModel.DataAnnotations; using System.Text.RegularExpressions; namespace ProjectName.Models { public class CommonValidations { [AttributeUsage(AttributeTargets.Field | AttributeTargets.Property, AllowMultiple = true, Inherited = true)] public sealed class EmailFormatValidAttribute : ValidationAttribute { public override bool IsValid(object value) { if (value != null) { var expression = @"^[a-zA-Z][\w\.-]*[a-zA-Z0-9]@[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z]$"; return Regex.IsMatch(value.ToString(), expression); } else { return false; } } } } } And here's the code that I want to use the validation from: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.ComponentModel; using System.ComponentModel.DataAnnotations; using Growums.Models; namespace ProjectName.Models { public class PrivacyModel { [Required(ErrorMessage="Required")] [EmailFormatValid(ErrorMessage="Invalid Email")] public string Email { get; set; } } }

  • Save as DialogBox to save textbox content to a newfile using asp.net

    - by user195114
    I want the users to type their text in the given textbox and on clicking on createNewFile Button, a SaveAs Dialogbox should popup and the users should browse through the location and save the file as desired. I have tried some thing but (1) the dialog box goes behind the application (2) when run, dialogbox opens 3 times, means it executes 3 times REPLY TO THE POST protected void btnNewFile_Click(object sender, EventArgs e) { StreamWriter sw = null; try { SaveFileDialog sdlg = new SaveFileDialog(); DialogResult result = sdlg.ShowDialog(); sdlg.InitialDirectory = @"C:\"; sdlg.AddExtension = true; sdlg.CheckPathExists = true; sdlg.CreatePrompt = false; sdlg.OverwritePrompt = true; sdlg.ValidateNames = true; sdlg.ShowHelp = true; sdlg.DefaultExt = "txt"; // sdlg.ShowDialog = Form.ActiveForm; string file = sdlg.FileName.ToString(); string data = txtNewFile.Text; if (sdlg.ShowDialog() == DialogResult.OK) { sw.WriteLine(txtNewFile.Text); sw.Close(); } if (sdlg.ShowDialog() == DialogResult.Cancel) { sw.Dispose(); } //Save(file, data); } catch { } finally { if (sw != null) { sw.Close(); } } } private void Save(string file, string data) { StreamWriter writer = new StreamWriter(file); SaveFileDialog sdlg1 = new SaveFileDialog(); try { if (sdlg1.ShowDialog() == DialogResult.OK) { writer.Write(data); writer.Close(); } else writer.Dispose(); } catch (Exception xp) { MessageBox.Show(xp.Message); } finally { if (writer != null) { writer.Close(); } } } I have tried this.

  • ASP.NET MVC SSL POST Error

    - by RyanFetz
    I have a Logon page in a MVC (1.0) application that I am securing with SSL, I have an attribute that inspects the request for the page and redirects to a https uri when it is requested with http. This all works, however when I post the form content i get the following error: The parameters dictionary contains a null entry for parameter 'rememberMe' of non-nullable type 'System.Boolean' for method 'System.Web.Mvc.ActionResult LogOn(System.String, System.String, Boolean, System.String)' in 'DAC.US.Web.Portal.Controllers.AccountController'. To make a parameter optional its type should be either a reference type or a Nullable type. Parameter name: parameters here is the controller code... // // GET: /Account/LogOn [RequiresSSL] public ActionResult LogOn(string ReturnUrl) { if (TempData["Message"] != null) ViewData["Message"] = TempData["Message"]; TempData["Message"] = null; ViewData["ReturnUrl"] = ReturnUrl ?? "/Home"; return View(); } Again, the RequireSSL Attribute works, but the POST from that SSL uri does not. What is not working?

  • c# ASP HttpResponse with redirect causes HTTP 302

    - by acnse
    Hi, I have a flow of web pages A and B. On the web page A, I do a "Response.Redirect("B.aspx"); The page B needs a client certificate. When the redirect is done I see a popup asking for a client certificate. I select the correct certificate, which is retrieved from a smart card, and then I insert the pin. Right after, I see a page saying that the connection was lost, and I receive an HTTP 302. I never reach the page B.aspx. I tried to add the following line "Response.RedirectLocation = "B.aspx"; but with no success too. Any hints? Thanks

  • ASP.NET AJAX UpdatePanel problem

    - by Velika
    I'll try and be concise: 1) I have a dropdownlist with Autopostback set to TRUE 2) I have an UpdatePanel that contains a Label. 3) When the downdownlist selection is changed, I want to update the label. Problem: Focus is lost on the dropdownlist, forcing the user to click on the dropdownlist to reset focus back to the control. My "solution": In the DropDownList_SelectionChanged event, set focus back to the drop down list: dropdownlist1.focus() Problem: While this works great in IE, Firefox and Chrome change the scroll position such that the control which was assigned focus is positioned at the bottom on the visible portion of the browser window. This is often a very disorientating side effect. How can this be avoided so it works in FF as it does in IE?
