  • How to return the full file path in a C# / ASP.NET web application?

    - by salvationishere
    This should be really simple, but I have tried many solutions posted on the internet so I thought I'd give this a try here. I have a VS 2008 web application that I need to capture the full file path (directories and file name) from the selected file. So user selects a file and then clicks on one of the buttons which transfers control to my code for processing. So how do I get the file path? I can get the file name, but not the path. Thanks!

  • How do i have optional parameter but still validate them in asp.net mvc routing ?

    - by ooo
    I have this route that i just added routes.MapRoute( "MyRoute", "MyController/{action}/{orgId}/{startDate}/{endDate}", new { controller = "MyController", action = "MyAction", orgId = 0, startDate = DateTime.Today.AddMonths(-1), endDate = DateTime.Today }, new { action = new FromValuesListConstraint(new string[] { "MyAction", "MyActionEx" }), orgId = new IntegerRouteConstraint(), startDate = new DateTimeRouteConstraint(), endDate = new DateTimeRouteConstraint() } when i put in this url, it resolves down to the default route (controller, action,id) and the above rout does not catch this url: http://localhost:1713/MyController/MyAction/16 But this below works fine. http://localhost:1713/MyController/MyAction/16/11-May-10/11-May-10 my question is that i thought both would work as i am giving default values to the startDate and enddate fields i tested this using the RouteDebugger and this route turned up false how can i have these last two parameter as optional but still have the validation ?

  • Asp.net Mvc - Kigg: Maintain User object in HttpContext.Items between requests.

    - by Pickels
    Hallo, first I want to say that I hope this doesn't look like I am lazy but I have some trouble understanding a piece of code from the following project. http://kigg.codeplex.com/ I was going through the source code and I noticed something that would be usefull for my own little project I am making. In their BaseController they have the following code: private static readonly Type CurrentUserKey = typeof(IUser); public IUser CurrentUser { get { if (!string.IsNullOrEmpty(CurrentUserName)) { IUser user = HttpContext.Items[CurrentUserKey] as IUser; if (user == null) { user = AccountRepository.FindByClaim(CurrentUserName); if (user != null) { HttpContext.Items[CurrentUserKey] = user; } } return user; } return null; } } This isn't an exact copy of the code I adjusted it a little to my needs. This part of the code I still understand. They store their IUser in HttpContext.Items. I guess they do it so that they don't have to call the database eachtime they need the User object. The part that I don't understand is how they maintain this object in between requests. If I understand correctly the HttpContext.Items is a per request cache storage. So after some more digging I found the following code. internal static IDictionary<UnityPerWebRequestLifetimeManager, object> GetInstances(HttpContextBase httpContext) { IDictionary<UnityPerWebRequestLifetimeManager, object> instances; if (httpContext.Items.Contains(Key)) { instances = (IDictionary<UnityPerWebRequestLifetimeManager, object>) httpContext.Items[Key]; } else { lock (httpContext.Items) { if (httpContext.Items.Contains(Key)) { instances = (IDictionary<UnityPerWebRequestLifetimeManager, object>) httpContext.Items[Key]; } else { instances = new Dictionary<UnityPerWebRequestLifetimeManager, object>(); httpContext.Items.Add(Key, instances); } } } return instances; } This is the part where some magic happens that I don't understand. I think they use Unity to do some dependency injection on each request? In my project I am using Ninject and I am wondering how I can get the same result. I guess InRequestScope in Ninject is the same as UnityPerWebRequestLifetimeManager? I am also wondering which class/method they are binding to which interface? Since the HttpContext.Items get destroyed each request how do they prevent losing their user object? Anyway it's kinda a long question so I am gradefull for any push in the right direction. Kind regards, Pickels

  • How to globalize ASP.NET MVC views (decimal separators in particular)?

    - by Pawel Krakowiak
    I'm working with the NerdDinner sample application and arrived at the section which deals with the Virtual Earth map. The application stores some values for the longitude and latitude. Unfortunately on my system floating point numbers are stored with a comma as the decimal separator, not a dot like in the US. So if I have a latitude of 47.64 it's retrieved and displayed as 47,64. Because that value is passed in a function call to the Virtual Earth API it fails at that point (e.g. JavaScript API expects 47.64, -122.13, but gets 47,64, -122,13). I need to make sure that the application always uses dots. In a WebForms app I would have a common class which overrides the System.Web.UI.Page.InitializeCulture() method and I would be inheriting my pages from that class. I am not sure about how to do the same with MVC. Do I need a customized ViewPage or something? Is there an easy way to solve this? Examples?

  • Saving a list of items in Application State ASP.NET MVC ?

    - by Calibre2010
    Hi Guys, I'm having a bit of trouble with knowing how I can save items from a list I have in Application state in the global.asax as- Application[""]. My controller basically takes in some user input, I then pass this to another classes Method as parameters it gets added to a list all the time. This data thats getting added to the list I want to store it, but without using a db. By using Application State. . I have been instantiating this class and calling its method to return the list of items but I dont think Application State is saving it. Here is what I have so far. . protected void Application_Start() { RegisterRoutes(RouteTable.Routes); TimeLineInformation t = new TimeLineInformation(); IList<SWTimeEnvInfoDTO> g = t.getInfo(); Application["AppID"] = g; } ^ Global.asax IList<SWTimeEnvInfoDTO> result = new List<SWTimeEnvInfoDTO>(); public void returnTimeLineInfo(string SWrelease, string EnvName, DateTime SDate, DateTime EDate) { SWTimeEnvInfoDTO myDTO = new SWTimeEnvInfoDTO(); myDTO.softwareReleaseName = SWrelease; myDTO.environmentName = EnvName; myDTO.StartDate = SDate; myDTO.EndDate = EDate; result.Add(myDTO); getInfo(); } public IList<SWTimeEnvInfoDTO> getInfo() { return result; } ^ class im calling The SWTimeEnvInfoDTO type has get and set methods for the data. I am calling the application from a View as well. It works with a string Application["AppID"] = "fgt"; and shows this once i read it from my view.

  • Are there any good resources on developing ASP.NET for Windows CE Internet Explorer?

    - by IronicMuffin
    I've been tasked with creating a web app to be consumed by a mobile device sporting Windows CE 5.0 (and some with Windows CE 4.2). I've found a host of things that seem to work fine in IE6 on my desktop, but fail when rendered in IE for Windows CE. IE6 is bad enough as it is...does it lose any more functionality on an embedded system? Are there quirks that a developer would need to know about? AJAX seems extremely unlikely. JavaScript seems quirky when linking to a .js file. Panels with scrollbars are finicky. Textboxes can't get focus. DefaultButtons on a form don't work. Any help or resources you can provide would be greatly appreciated.

  • How to Filter ADO.NET data using a Full Text Seach (FTS) field?

    - by ActionFactory
    Hi All, We are using ADO.NET dataservices & are building URL based filters. Example: /Customers?filter=City eq 'London' We now need to filter on a Full Text 'tags' Field. WAS HOPING FOR: /Customers?filter=Tag like 'Friendly' PROBLEM: ADO.NET does not have a LIKE operator. ADO.NET does not seem to like FTS (It is not finding a match - because it is not parsing through the CSV's) Any ideas how to make this work? THX

  • ASP.NET MVC jQuery: Shoud we be concerned about a lot of jQuery/javascript on a View?

    - by Mark Redman
    We are moving from WebForms to MVC and and using a lot of jQuery. I appears we have a lot of jQuery/JavaScript in our Views, is this common and are there any concerns about security. The obvious step is to refactor into plugins and more generic UserControls etc, but this jQuery would still be "visible" by looking at js files etc. We are validating everything on the server-side anyway but should we be concerned?

  • Why does this asp.net mvc unit test fail?

    - by Brian McCord
    I have this unit test: [TestMethod] public void Delete_Post_Passes_With_State_4() { //Arrange ViewResult result = stateController.Delete( 4 ) as ViewResult; var model = (State)result.ViewData.Model; //Act RedirectToRouteResult redirectResult = stateController.Delete( model ) as RedirectToRouteResult; var newresult = stateController.Delete( 4 ) as ViewResult; var newmodel = (State)newresult.ViewData.Model; //Assert Assert.AreEqual( redirectResult.RouteValues["action"], "Index" ); Assert.IsNull( newmodel ); } Here are the two controller actions that handle deleting: // // GET: /State/Delete/5 public ActionResult Delete(int id) { var x = _stateService.GetById( id ); return View(x); } // // POST: /State/Delete/5 [HttpPost] public ActionResult Delete(State model) { try { if( model == null ) { return View( model ); } _stateService.Delete( model ); return RedirectToAction("Index"); } catch { return View( model ); } } What I can't figure out is why this test fails. I have verified that the record actually gets deleted from the list. If I set a break point in the Delete method on the line: var x = _stateService.GetById( id ); The GetById does indeed return a null just as it should, but when it gets back to the newresult variable in the test, the ViewData.Model is the deleted model. What am I doing wrong?

  • ASP.NET MVC - How to Preserve ModelState Errors Across RedirectToAction?

    - by RPM1984
    Hi Guys, I have the following two action methods (simplified for question): [HttpGet] public ActionResult Create(string uniqueUri) { // get some stuff based on uniqueuri, set in ViewData. return View(); } [HttpPost] public ActionResult Create(Review review) { // validate review if (validatedOk) { return RedirectToAction("Details", new { postId = review.PostId}); } else { ModelState.AddModelError("ReviewErrors", "some error occured"); return RedirectToAction("Create", new { uniqueUri = Request.RequestContext.RouteData.Values["uniqueUri"]}); } } So, if the validation passes, i redirect to another page (confirmation). If an error occurs, i need to display the same page with the error. If i do return View(), the error is displayed, but if i do return RedirectToAction (as above), it loses the Model errors. I'm not surprised by the issue, just wondering how you guys handle this? I could of course just return the same View instead of the redirect, but i have logic in the "Create" method which populates the view data, which i'd have to duplicate. Any suggestions?

  • I need to know how to create a custom webform template in ASP.NET that allows me to pick a master pa

    - by Pete
    Using Visual Studio 2008, I need to create a custom web form that when picked acts like the web content form, by providing a dialog that lets you pick a master page. I have looked through the webform.zip template and thought I had a clue, but trying different combinations has baffled me as it either doesn't appear or doesn't work. Also when you set the project type to Web and sub project type to CSharp it doesn't appear, so I don't know if this part of the cause, because I would of hoped that the SupportsMasterPage element would of caused this dialog to appear, if it is a web item, but no luck. Frown Any ideas? p.s. I have used my googling resources to the maximum so unsure what to do.

  • Is there a recommended logging path/folder for ASP.NEt applications?

    - by the-locster
    Currently we use log4net and create a new folder (usually below C:) with write and create access rights for the worker process user. Is there perhaps a standard windows folder we should or could be using such as LOCALAPPDATA? I'm guessing that LOCALAPPDATA is a bad choice in the general case because IIS users tend to be non-interactive users and thus I don't think they have the usual user folder structrues available.

  • How make data entry using autogenerated texboxes in ASP.NET MVC?

    - by elbaid
    I'm asking a simple question on how to do data entry when using a custom number of textboxes. Usualy, in books, or tutorials, we consider a fixed number of entries for the controller. But what if the number of entries varies? For a concrete example, imagine some number of products which we need to enter quantity. How to manage this if one time we have 3 products and the other time we have 10 products? Thank you.

  • Detecting if MSBuild/.net 4 is installed from C# code running on 3.5?

    - by Michael Stum
    I have an application that is running on .net 3.5 SP1 and that is supposed to check if .net 4 is installed. Actually, I'm more interested if MSBuild v4 is installed, which would boil down to a simple File.Exists(@"C:\Windows\Microsoft.NET\Framework\v4.0.30319\msbuild.exe"); However, apart from the fragility of the 4.0.30319 Version (and the Windir, but that's easy to solve), I wonder if there is a more appropriate way, like an API?

  • Paging using Linq-To-Sql based on two parameters in asp.net mvc...

    - by Pandiya Chendur
    As two parameters i say currentPage and pagesize .....I thus far used sql server stored procedures and implemented paging like this, GO ALTER PROCEDURE [dbo].[GetMaterialsInView] -- Add the parameters for the stored procedure here @CurrentPage INT, @PageSize INT AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; SELECT *,ROW_NUMBER() OVER (ORDER BY Id) AS Row FROM ( SELECT *,ROW_NUMBER() OVER (ORDER BY Id) AS Row FROM InTimePagingView ) AS InTimePages WHERE Row >= (@CurrentPage - 1) * @PageSize + 1 AND Row <= @CurrentPage*@PageSize SELECT COUNT(*) as TotalCount FROM InTimePagingView SELECT CEILING(COUNT(*) / CAST(@PageSize AS FLOAT)) NumberOfPages FROM InTimePagingView END Now i am using Linq-to-sql and i use this, public IQueryable<MaterialsObj> FindAllMaterials() { var materials = from m in db.Materials join Mt in db.MeasurementTypes on m.MeasurementTypeId equals Mt.Id where m.Is_Deleted == 0 select new MaterialsObj() { Id = Convert.ToInt64(m.Mat_id), Mat_Name = m.Mat_Name, Mes_Name = Mt.Name, }; return materials; } Now i want to return the records,TotalCount where i use Total count to generate pagenumbers..... Is this possible... Any suggestion... EDIT: Just found this... NorthWindDataContext db = new NorthWindDataContext(); var query = from c in db.Customers select c.CompanyName; //Assuming Page Number = 2, Page Size = 10 int iPageNum = 2; int iPageSize = 10; var PagedData = query.Skip((iPageNum - 1) * iPageSize).Take(iPageSize); ObjectDumper.Write(PagedData);

  • ASP.NET MVC View Not posting back to Post method and expecting a parameterless Constructor?

    - by VJ
    Hi, I am trying to post back some data using a viewmodel i have created and it works for me for one of the projects.But I am doin this right now public ActionResult Foo(string userkey) { vm.Value="Xvalue"; return View(vm); } [HttpPost] public ActionResult Foo( MyViewModel vm) { // process input if (inputOK) string value=vm.Value return RedirectToAction("Index"); return View(); } public class MyViewModel { public string Value { get; set; } public SomeClass newobj {get;set;} } public class SomeClass { public int id{get;set;} public string str{get;set;} } So it on debugging never goes into the parameter method for Post although on the view i have added a form and a button that submits and the page inherits from the viewmodel.I get an error saying it expects a parameterless constructor how do I fix this ? . I wrote an post method with no parameters and it does go into that method

  • How do I download a file from an FTP server using FTP over SSL using .NET?

    - by atconway
    My post title almost states it all: How do I download a file from an FTP server using FTP over SSL using .NET? I have read a bit and there are several 3rd party components to purchase that wrap up this functionality. The deal is, this is a very specefic need and is not going to grow much, so if downloading a file from an FTP server using FTP over SSL can be done using the .NET Framework (i.e. System.Net namespace or something), then that would be best. I don't need a ton of functionality, but if for some reason coding against a secure FTP server is a nightmare or not doable through the .NET Framework BCL that would be nice to know, as a 3rd party .dll might be best. Thank you!

  • Retain a list of objects and pass it to the create/edit view when validation fails in ASP.NET MVC 2

    - by brainnovative
    I am binding a Foreign key property in my model. I am passing a list of possible values for that property in my model. The model looks something like this: public class UserModel { public bool Email { get; set; } public bool Name { get; set; } public RoleModel Role { get; set; } public IList<RoleModel> Roles { get; set; } } public class RoleModel { public string RoleName { get; set; } } This is what I have in the controller: public ActionResult Create() { IList<RoleModel> roles = RoleModel.FromArray(_userService.GetAllRoles()); UserModel model = new UserModel() { Roles = roles }; return View(model); } In the view I have: <div class="editor-label"> <%= Html.LabelFor(model => model.Role) %> </div> <div class="editor-field"> <%= Html.DropDownListFor(model => model.Role, new SelectList(Model.Roles, "RoleName", "RoleName", Model.Role))%> <%= Html.ValidationMessageFor(model => model.Role)%> </div> What do I need to do to get the list of roles back to my controller to pass it again to the view when validation fails. This is what I need: [HttpPost] public ActionResult Create(UserModel model) { if (ModelState.IsValid) { // insert logic here } //the validation fails so I pass the model again to the view for user to update data but model.Roles is null :( return View(model); } As written in the comments above I need to pass the model with the list of roles again to my view but model.Roles is null. Currently I ask the service again for the roles (model.Roles = RoleModel.FromArray(_userService.GetAllRoles());) but I don't want to add an extra overhead of getting the list from DB when I have already done that.. Anyone knows how to do it?
