  • Converting VS2008 Solution to VS2010 Creates compile errors in ASP.NET 3.5 SP1

    - by Lukasz
    I am converting a large solution from Visual Studio 2008 to Visual Studio 2010. The conversion completes without errors. When I go to build the solution one particular section of the application throws error but it didn't when the solution was 2008. Error 1 Could not load file or assembly 'System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. C:\MyProject\Results\Result.ascx 3 And C:\CMyProject\Results\Result.ascx(3): Build (web): Could not load file or assembly 'System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. The dll is in the bin and it is not in the GAC. The .refresh file is pointing to the correct location. And all sections in the Web.Config are there, if you need to see them let me know. I have gone over the fixes I found online and nothing seems to help. I would really appreciate if someone could help me or point me in the right direction? Thank You.

  • ASP.NET MVC ,Maintaining Model State between Ajax requests

    - by Podders
    problem: On first full page request, my controller invokes an applicationServices Layer (Web Service Proxy to my business tier) in order to populate a collection of current services that is stored in my own controller base class property. This is then to be displayed within a view. Everything within the context of that controller has access to this "Services Collection". Now when i make further calls to the same action method via an AJAX Call, i obviously hitt a different instance of that controller meaning my services collection is empty. So other than re-getting the whole collection again, where would i store this collection so it gets persisted between ajax requests? Should i persist it as a seperate DomainModel Object, Session object?....as ViewData is not working for me obv. Excuse my MVC ignorance :) Any help would be greatly appreciated :)

    - by Steve
    This is crazy, I have been trying for hours to get this to work. My client wants to be able to reset password for uses who have forgotten them The only parameter he has is the UserName. He does NOT want the user to be able to reset the password themselves, no that would be too easy...ARGHHHHH!! Anyway, if anyone has any suggestions how I could reset someones password or give them a new temp password somehow, that would be greatly appreciated. Thank you, Steve

    - by Andrew
    I am using a crystal reports through crystal report viewer server side control in a webform. I am using a webform because the crystal report viewer provides an easy way to export to PDF and to Excel. My problem is that when I deploy to the server, the crystal report .rpt file does not get copied to the target folder. My solution structure looks like this: Solution |-Content |-Controllers |-Models |-Views |-etc... |-Reports |-Default.aspx |-Report.rpt On the server, the Report.rpt file is missing after I publish.

  • How to assign .net membership roles to individual database records

    - by mdresser
    I'm developing a system where we want to restrict the availability of information displayed to users based on their roles. e.g. I have a tabled called EventType (ID, EventTypeDescription) which contains the following records: 1, 'Basic Event' 2, 'Intermediate Event' 3, 'Admin Event' What I need to achieve is to filter the records returned based on the username (and hence role) of the logged-in user. e.g if an advanced user is logged in they will see all the event types, if the standard user is logged in they will only see the basic event type etc. Ideally id like to do this in a way which can be easily extended to other tables as necessary. So I'd like to avoid simply adding a 'Roles' field to each table where the data is user context sensitive. One idea I'm thinking of is to create some kind of permissions table like: PermissionsTable ( ID, Aspnet_RoleId, TableName, PrimaryKeyValue ) this has the drawback of using this is obviously having to use the table name to switch which table to join onto. Edit: In the absence of any better suggestions, I'm going to go with the last idea I mentioned, but instead of having a TableName field, I'm going to normalise the TableName out to it's own table as follows: TableNames ( ID, TableName ) UserPermissionsTable ( ID, Aspnet_UserId, TableID, PrimaryKeyValue )

  • VB.NET, templates, reflection, inheritance, feeling adrift

    - by brovar
    I've just made myself up a problem and am now wondering how to solve it. To begin with, I'm using some third-party components, including some calendar controls like schedule and timeline. They're used in the project classes more or less like that: Friend Class TimeBasedDataView 'some members End Class Friend Class ScheduleDataView Inherits TimeBasedDataView Public Schedule As Controls.Schedule.Schedule 'and others End Class Friend Class TimeLineDataView Inherits TimeBasedDataView Public TimeLine As Controls.TimeLine.TimeLine 'and others End Class (Hmm, code coloring fail, never mind...) Now, to allow managing the look of data being presented there are some mechanisms including so called Style Managers. A lot of code in them repeats, varying almost only with the control it maintains: Friend Class TimeLineStyleManager Private m_TimeLine As TimeLineDataView Private Sub Whatever() m_TimeLine.TimeLine.SomeProperty = SomeValue End Sub End Class Friend Class ScheduleStyleManager Private m_Schedule As ScheduleDataView Private Sub Whatever() m_Schedule.Schedule.SomeProperty = SomeValue End Sub End Class I was wondering if I could create some base class for those managers, like Friend Class TimeBasedCtrlStyleManagerBase(Of T As TimeBasedDataView) Private m_Control As T 'and others End Class which would unify these two, but I've got lost when it came to maintaining two components that have nothing in common (except their properties' names, etc.). Type reflection maybe? I'll be grateful for any advice ;)

  • DataBinding a DropDownList in ASP.NET MVC 2

    - by Daniel Coffman
    I'm extremely frustrated trying to switch to MVC after a couple years of webforms development. Here's my extremely simple problem that I can't manage to solve: I have a list of States in a table called StateProvince. I have a DropDownList. I want the DropDownList to display all of the States in the StateProvince table and post the selected state back on HTTP PUT. This is what I'm doing: <%: Html.DropDownListFor(model = model.StateProvinceId, new SelectList(Model.StateProvinces, "StateProvinceId", "Name") )% I'm getting an Object reference not set to an instance of an object. Why? How can I make this work? Keep it simple, I know nothing about MVC.

  • Need an ASP.NET MVC long running process with user feedback

    - by Jason
    I've been trying to create a controller in my project for delivering what could turn out to be quite complex reports. As a result they can take a relatively long time and a progress bar would certainly help users to know that things are progressing. The report will be kicked off via an AJAX request, with the idea being that periodic JSON requests will get the status and update the progress bar. I've been experimenting with the AsyncController as that seems to be a nice way of running long processes without tying up resources, but it doesn't appear to give me any way of checking on the progress (and seems to block further JSON requests and I haven't discovered why yet). After that I've tried resorting to storing progress in a static variable on the controller and reading the status from that - but to be honest that all seems a bit hacky! All suggestions gratefully accepted!

  • ASP.net MVC - Check status request

    - by vdhant
    Hi guys Just wondering if its possible to get the status of a request from another request? To help provide some context, I want to use ajax to upload some files to the server. When the upload is started I want triggered another ajax request that checks to see how much of the file has been uploaded (or in other words how big was the other request and how far through receiving the request is the server). I was thinking that I could use a guid or something similar to ensure that I am checking the status of the right request. But how do I check the status of another request??? Cheers Anthony

  • Design Time Attribute For CSS Class in ASP.net Custom Server Control

    - by Jon P
    Hopefully some Custom Control Designers/Builders can help I'm attempting to build my first custom control that is essential a client detail collection form. There are to be a series of elements to this form that require various styles applied to them. Ideally I'd like the VS 2005/2008 properties interface to be able to apply the CSSClass as it does at the control level, i.e. with a dropdown list of available CSS Clases. Take for example the Class to be applied to the legend tag /// <summary>Css Class for Legend</summary> [Category("Appearance")] [Browsable(true)] [DefaultValue("")] //I am at a loss as to what goes in [Editor] [Editor(System.Web.UI.CssStyleCollection), typeof(System.Drawing.Design.UITypeEditor))] public string LegendCSSClass { get { return _LegendCSSClass; } set { _LegendCSSClass = value; } } I have tried a couple of options, as you can see from above, without much luck. Hopefully there is something simple I am missing. I'd also be happy for references pertaining to the [Editor] attribute

  • ado.net managing connections

    - by madlan
    Hi, I'm populating a listview with a list of databases on a selected SQL instance, then retrieving a value from each database (It's internal product version, column doesn't always exist) I'm calling the below function to populate the second column of the listview: item.SubItems.Add(DBVersionCheck(serverName, database.Name)) Function DBVersionCheck(ByVal SelectedInstance As String, ByVal SelectedDatabase As String) Dim m_Connection As New SqlConnection("Server=" + SelectedInstance + ";User Id=sa;Password=password;Database=" + SelectedDatabase) Dim db_command As New SqlCommand("select Setting from SystemSettings where [Setting] = 'version'", m_Connection) Try m_Connection.Open() Return db_command.ExecuteScalar().trim m_Connection.Dispose() Catch ex As Exception 'MessageBox.Show(ex.Message) Return "NA" Finally m_Connection.Dispose() End Try End Function This works fine except it's creating a connection to each database and leaving it open. My understanding is the close()\dispose() releases only the connection from the pool in ado rather than the actual connection to sql. How would I close the actual connections after I've retrieved the value? Leaving these open will create hundreds of connections to databases that will probably not be used for that session.

  • Multiple Default Routes in ASP.NET MVC to different Default Actions

    - by Alex
    I have multiple controllers with different actions (no "Index" actions). The actions I consider "default" actions, are named differently. I want to create default routes for their names and have the first available action (from my list of default actions) executed if only the controller name is provided in the route. So, for example, I have the following actions which I want to consider default and want checked for their existence in a controller in this order: List() Draw() ViewSingle() The routing should somehow search for /{controller} and then take the first available action from the list above as default action, e.g.: /ControllerA -> ControllerA.List() /ControllerB -> ControllerB.Draw() /ControllerC -> ControllerC.ViewSingle() /ControllerD -> ControllerD.Draw() /ControllerE -> ControllerE.List() Is this possible? I tried creating additional Default actions like this but couldn't get it to work: routes.MapRoute("Default1", "{controller}/{action}", new { controller = UrlParameter.Optional, action = "List" } routes.MapRoute("Default2", "{controller}/{action}", new { controller = UrlParameter.Optional, action = "Draw" } routes.MapRoute("Default3", "{controller}/{action}", new { controller = UrlParameter.Optional, action = "ViewSingle" } Help?

  • asp.net mvc - reusing pages/controllers in workflow

    - by fregas
    I have 2 workflows: 1) the user signs up for the first time. They see 3 different screens, their basic user information, their credit card, and some additional profile information. They complete these 3 steps in a wizard like fashion, where each time they hit "submit" they leave the current screen and move on to the next. 2) the user already is signed up. He has links in the navigation to these 3 seperate pages. He can update them in any order. When he hits save, he doesn't leave the page he's on, it just shows something at the top that says "Credit Card Info saved..." or whatever. Possibly using ajax or maybe a full page refresh. I would like to reuse the code not only the view but also in the controller for these 3 screens between the two workflows, but without a ton of if...then logic to determine where to go next depending on whether its a first signup in the wizard or updating individual parts of a profile. Any ideas?
