  • In partial view: "The model item passed into the dictionary is of type"

    - by Dave
    I lack understanding of some basic MVC concepts, despite all my searching. I created an MVC project in Visual Studio, which contains the partial view _LogOnPartial.shtml. I just want to access information within the view pertaining to the user, to put in a user dropdown menu. When I try to put this at the top of the partial view cshtml page I get the above error: @model MyProject_MVC.Models.UserRepository When I try this I also get an error: @Html.Partial("_LogOnPartial", MyProject_MVC.Models.UserRepository) 'MyProject_MVC.Models.UserRepository' is a 'type', which is not valid in the given context

  • How to remove dangerous characters(ie script tags)?

    - by chobo2
    I am wondering is there any sort of C# class or 3rd party library that removes dangerous characters such as script tags? I know you can use regex but I also know people can write their script tags so many ways that you can fool the regex into thinking it is OK. I also heard that HTML Agility Pack is good so I am wondering is there any script removal class made for it?

  • How to use Bind Prefix?

    - by chobo2
    Hi Say if I had this table in my db: Product It had ProductId ProductName ProductType Now for whatever reason I can't name my textboxes ProductName and ProductType so now my View Method would look like this public ViewResult Test([Bind(Exclude ="ProductId")] Product) So now through my playing around nothing would be matched in this product since they have different names. So I guess this is where Prefix would come in but I don't know how to use it. Nor how do I use it and Exclude at the same time. Can someone give me an example?

  • Visual Studio Code Analysis - Does Microsoft follow it themselves?

    - by Oskar Kjellin
    Did a quick search but could not find anything about this. I guess all of you know that the Visual Studio Code Analysis is quite nitpicking and gives warnings about a lot of things. Does anybody know how well Microsoft follow this themselves..? That is, if I were to run a code analysis on their assemblies, would the warnings be none or very few (perhaps surpress warning with a justification..?).

  • Linq Scope Problem + Reduce Repeated Code

    - by Tom Gullen
    If the parameter is -1, it needs to run a different query as to if an ID was specified... how do I do this? I've tried initialising var q; outside the If block but no luck! // Loads by Entry ID, or if -1, by latest entry private void LoadEntryByID(int EntryID) { IEnumerable<tblBlogEntry> q; if (EntryID == -1) { q = ( from Blog in db.tblBlogEntries orderby Blog.date descending select new { Blog.ID, Blog.title, Blog.entry, Blog.date, Blog.userID, Comments = ( from BlogComments in db.tblBlogComments where BlogComments.blogID == Blog.ID select BlogComments).Count(), Username = ( from Users in db.yaf_Users where Users.UserID == Blog.userID select new { Users.DisplayName }) }).FirstOrDefault(); } else { q = ( from Blog in db.tblBlogEntries where Blog.ID == EntryID select new { Blog.ID, Blog.title, Blog.entry, Blog.date, Blog.userID, Comments = ( from BlogComments in db.tblBlogComments where BlogComments.blogID == Blog.ID select BlogComments).Count(), Username = ( from Users in db.yaf_Users where Users.UserID == Blog.userID select new { Users.DisplayName }) }).SingleOrDefault(); } if (q == null) { this.Loaded = false; } else { this.ID = q.ID; this.Title = q.title; this.Entry = q.entry; this.Date = (DateTime)q.date; this.UserID = (int)q.userID; this.Loaded = true; this.AuthorUsername = q.Username; } } My main aim is to reduce repeating code

  • Global Import Aliasing in .NET

    - by Josh Stodola
    Using import aliasing in a single class, we can reference class library namespaces by assigning our own custom alias like this: Imports Db = Company.Lib.Data.Objects And then we are able to reference the classes inside of Company.Lib.Data.Objects by using the Db alias that we assigned. Is it possible to do this at the global level so that the alias is applied to the entire solution instead of the given file? Currently, we are working with web applications, so I was hoping we could add something to web.config, but I am also interested in whether or not this is possible with windows forms, console apps, and/or class libraries.

  • MonoDevelop seems to hang (not unresponsive) when building csprojs

    - by Michael Shimmins
    Building a solution from Visual Studio in mono develop seems to have some issues. I'm hoping someone else has experienced this and has some suggestions. The actual dcms process goes pretty quickly, but in between projects it hangs after printing: Building: XXX.YYY.ZZZ (Debug) After a few minutes (been 10 so far on this current run), it jumps to: Performing main compilation... /Library/Frameworks/Mono.framework/Versions/2.10.1/bin/dmcs /noconfig "/... Build complete -- 0 errors, 0 warnings Building: XXX.YYY.ZZZ (Debug) Then hangs again for another few minutes. This is a sln file with 29 csproj projects in it that was originally created in Visual Studio 2010. I'm wondering if there is a better way to set this up - potentially a native MD file format?

  • How to access Session values from layers beneath the web application layer.

    - by Matthew Vines
    We have many instances in our application where we would like to be able to access things like the currently logged in user id in our business domain and data access layer. On log we push this information to the session, so all of our front end code has access to it fairly easily of course. However, we are having huge issues getting at the data in lower layers of our application. We just can't seem to find a way to store a value in the business domain that has global scope just for the user (static classes and properties are of course shared by the application domain, which means all users in the session share just one copy of the object). We have considered passing in the session to our business classes, but then our domain is very tightly coupled to our web application. We want to keep the prospect of a winforms version of the application possible going forward. I find it hard to believe we are the first people to have this sort of issue. How are you handling this problem in your applications?

  • GridView and multiple postbacks problem

    - by Jonn
    I have a grid view containing checkboxes and a great deal of problems surrounding it. First of all the page on_load and on_init gets called twice. The first call says it's a postback and the second isn't. If I check for postbacks, during the second call the change of state (i.e. A button_click event that was supposed to refresh the data in the grid) that triggered during the first call does not register. If I don't check for postbacks, checkboxes in the GridView do not retain its state by the second call to OnLoad/OnInit.

  • How to get around circular references in Visual Studio Web Project?

    - by joebeazelman
    I am trying to create a set of WCF web services for an existing website that uses web site instead of a web application project. I would like to create a DLL that I drop into the Bin folder instead of writing all my code inside the App_Code directory. Ideally, I want to create a project and reference it from the web site, but I am running into a difficult situation. The DLL will need to reference configuration and other DLLs located inside the bin folder of the website causing a circular reference. How do I get around this issue?

  • Cross-browser method for hiding page elements until all content is loaded to prevent layout from appearing broken during load?

    - by Ryan
    I have an issue where due to some elements loading faster than others, the page looks broken for a few seconds at the start. An example is the CSS Pie behavior that allows me to do curved corners in IE, it appears before it becomes curved which looks bad. What would be ideal would be it somehow knowing when everything is loaded and then appear all at once, possibly including some kind of elegant visual way of not making the user feel impatient... any ideas or common tricks for doing this?

  • Overloading Controller Actions

    - by DaveDev
    Hi Guys I was a bit surprised a few minutes ago when I tried to overload an Action in one of my Controllers I had public ActionResult Get() { return PartialView(/*return all things*/); } I added public ActionResult Get(int id) { return PartialView(/*return 1 thing*/); } .... and all of a sudden neither were working I fixed the issue by making 'id' nullable and getting rid of the other two methods public ActionResult Get(int? id) { if (id.HasValue) return PartialView(/*return 1 thing*/); else return PartialView(/*return everything*/); } and it worked, but my code just got a little bit ugly! Any comments or suggestions? Do I have to live with this blemish on my Controllers? Thanks Dave

  • Why Response.Write behavior varies in the given scenario?

    - by Sri Kumar
    Hello All, When i POST the page using the following code, the Response.write("Hey") doesn't write the content ("Hello") to the parent page <form method="post" name="upload" enctype="multipart/form-data" action="http://localhost:2518/Web/CrossPage.aspx?cmd=getvalue" > <input type="file" name="filename" /> <input type="submit" value="Upload Data File" name="cmdSubmit" /> </form> But When i use following code , and POST the data, the Response.write("Hey") can be obtained in the parent page HttpWebRequest requestToSender = (HttpWebRequest)WebRequest.Create("http://localhost:2518/Web/CrossPage.aspx?cmd=getvalue"); requestToSender.Method = "POST"; requestToSender.ContentType = "multipart/form-data"; HttpWebResponse responseFromSender = (HttpWebResponse)requestToSender.GetResponse(); string fromSender = string.Empty; using (StreamReader responseReader = new StreamReader(responseFromSender.GetResponseStream())) { fromSender = responseReader.ReadToEnd(); } In the CrossPage.aspx i have the following code if (!Page.IsPostBack) { NameValueCollection postPageCollection = Request.Form; foreach (string name in postPageCollection.AllKeys) { Response.Write(name + " " + postPageCollection[name]); } HttpFileCollection postCollection = Request.Files; foreach (string name in postCollection.AllKeys) { HttpPostedFile aFile = postCollection[name]; aFile.SaveAs(Server.MapPath(".") + "/" + Path.GetFileName(aFile.FileName)); } Response.Write("Hey"); } I don't have any code in the Page_Load event of parent page.? What could be the cause? I need to write the "hey" to the Parent page using the first scenario. Both the application are of different domain. Edit: "Hey" would be from the CrossPage.aspx. I need to write this back to the Parent Page

  • Livevalidation clientside validation - can you control the position of the validation messages?

    - by JK
    I'm using LiveValidaion for my clientside validation http://livevalidation.com/ and DataAnnotations for my validation rules. This all works fine except that the clientside error messages are only ever displayed to the right of the element being validated. Is it possible to move this validation message below the element being validated? Or even better, group all messages in a div at the top/bottom of the page? I dont see anything in their docs or examples
