Is it possible to validate property of a ASP.NET UserControl at compile time..
e.g. ID="1" shows an error
I have a public property called 'UploadDirectory'
I want to show error message when the directory is not present.I wrote following code for the public property but it works as expected at runtime only
/// <summary>
/// Format e.g. ~/UploadDirectory/
/// </summary>

I've noticed that my project builds successfully when I hit F6.But when I run it with F5 the compilation errors in my C# surface.Why is this?Is it because the JIT compilation happens when I debug with F5 but not when I build with F6?
View 6 RepliesI'm relatively new to actually publishing sites on my own..Anyway, right now I am using VS2008 to build / compile my web application and then publish it to the server. Simple enough, until I want to change several of the code behinds, and don't want to spend 30 minutes re-publishing several thousand documents.
I have been reading that publishing via VS is not the best approach, so I guess I have two questions:
1. Using VS2008, is there a way to build the project and publish only certain parts of the project such as the pre-compiled code or better yet have VS only update the code that has been changed on the server? I suppose I could simply publish it to my local drive and pick apart the files from there / is there a better way?
2. In your opinion what is the best deployment strategy?
I have an ASP.NET website that worked fine using and debugging in VS2008. I went through the upgrade process opening the solution in VS2010. I can run the site, but as I make changes in the app_code folder classes, they don't seem to commpile and warn me of compile-time errors. As soon as I get to a point that calls the class, the errors show up. Sounds JIT I guess, but this isn't how it was working in 08. Is there an option that was changed in the upgrade process? This is a large project, I really don't want to break something and not find out until some obscure page is opened.
View 1 RepliesWhen I'm building my web project it takes about 20 seconds to compile. Then when I try to browse to a web page in project, asp.net does its runtime compilation(another 20 seconds). I know I can't escape these steps because thats how asp.net works, just want to see if anyone has some kind of optimization to make these builds faster.

View 2 RepliesHow much time is spent compiling a view in ASP.NET?Of course I don't expect anyone to give me a number, but I think it's interesting to have an idea of how much time this takes because it could influence the way we implement things.For example, if the time is significant , then I might try to put every result that I need to display in the view in a model class instance (created just to hold the values in such a way that I don't even have to test for objects with null value) and then minimize to the maximum (uh?) the amount of C# code in the view thus decreasing the amount of time necessary to compile the view.Question Does this make sense? Give some thoughts on this one.
View 1 RepliesI am using TFS to build my MVC app. I cannot do it because I get lots of compile errors. I am using version 4 of .Net and MVC 2. On the build server I have the .Net framework 4.0 installed. It has been suggested that I should also download the MVC framework as well, but when I look on the net all I can find is this MVC framework; http://mvcframework.codeplex.com/ which does not seem to be relevant and does not work anyway.
One of the assemblies I am missing on the build server is System.Web.Mvc dll.Typical error messages include; "The type or namespace name 'Mvc' does not exist in the namespace 'System.Web' (are you missing an assembly reference?)"What do I need to do to fix this?
Specifically we're making our application compatible with the Out Of Process Session State server where all types saved in session must be serializable. Is there a way to see at compile time that any type put into HttpSessionState is marked with the Serializable attribute. Something along the lines of this 'non-valid' code
public static void Put<T>( string key, T value ) where T : IsMarkedWitheSerializableAttribute
{
HttpContext.Current.Session[key] = value;
}
We recently migrated to v4 of .net. We are running iis 7 in integrated mode. When the site first starts its slow. I get that - it compiles for the first time. The odd thing is then we will go to certain pages and it seems to compile again. The next time i go that page its very fast. Nothing exceptional with the second page - but once that is hit the rest of the site is fast.
View 1 RepliesFor the first time in my career, I'm working on an ASP.Net (v3.5) project that has been set up as a Visual Studio 2008/10 Web Site Project.
I'm not keen on this way of working this way for various reasons but for the moment and until such time as the company sees the virtue in working in an environment with namespaces, designer and project files etc., I have to continue with the existing codebase.
I've run into some odd issues since I began this but perhaps the oddest one of all is that althought VS lets me build the code, it doesn't reliably pick up compilation errors so these are not noticed until runtime.
I know the website model allows dynamic/hot compilation when a request is made for a specific but I can't see why it wouldn't do this when I manually (F5) build/rebuild the project. Its immensely annoying as you can imagine and I can't find a workaround.

I have a ProductService class that defines the following methods. It doesn't work, as I will explain further below, but it gives the compile error CS1061: 'ProductService' does not contain a definition for 'GetByid'. Unless I've dropped the ball on method overloading, why is the public overload of GetById not seen by other code?
public IEnumerable<Product> ListActiveByCatId(Guid catId) {
return _entityContext.Products
.Include("Category")
.Where(p => p.Category.id == catId);

Using VS2008 SP1, .NET 3.5 SP1, C# Web Application Project
As we know, Web Application Projects (unlike Web Site Projects) compile the entire site for deployment. We have discovered a situation where the visual studio compiler doesnt catch and error. Then when we deploy the dll to the website (or even just run it in the built in web server) it catches the error and displays it as a "compilation" error during runtime. This is obviously disturbing. Let me explain the error:
Take a single web page in a new C# web app project, such as the default.aspx. Add a checkbox. Create an event handler for the checked changed event. Note that it modifies the .aspx file to add oncheckedchanged="yourmethodhere" in the checkbox item. Compile and everything is fine.
Now change the name of the method in the .aspx file, say for yourmethodhere to yourmethodhere_1 and compile again. Note you havent change the code behind, so you SHOULD get a compile error. But you dont. Now if you deploy or debug it, you will get a compilation error during runtime.
Note: If you do exactly the same thing in a web SITE project, the validation compile that it does when you choose to "build" the project DOES catch this error. In other words, only c# web APPLICATION projects have this problem.
I'm working through the Mvc Music store tutorial on PDF. At page 52, near the bottom, is a line that reads:
<%: Html.EditorFor(model => Model.Album, new {Artists = Model.Artists, Genres = Model.Genres})%>
This line fails with an "unhandled compile" error when I run the program and enter "storemanager/edit/388" in the address bar. I have gone over every bit of code I can find and it compares perfectly to the tutorial.
Everytime I compile my asp .net project it states the following:
'Sessions' does not contain a definition for 'Select'.
In the page this happens on if I change something put it back and save and re-compile it tends to go ok, but at the moment it is happening every time. It does contain a definition for Select I can type it in plus the page does not show an error where this code is and works when it does compile ok?

View 1 RepliesIn development, our Asp.Net 4 website takes a fairly lengthy time to start after the project libraries are built
We do a fair amount of population of statics etc, but not enough to justify the length of time it takes the app to come up (probably 3-4 minutes)
We aren't building the website, just the libraries, and batch != true in the compilation element in the .config file.
I will try log some diagnostics, but any other pointers would be useful
The inline code
<% for (int i = 0; i < ThumbnailList.Items.Count; i++)
{ Response.Write("thumbnailViews[" + i.ToString() + "] = $find('" +
ThumbnailList.Items[i].FindControl("ThumbnailView").ClientID + "');
"); } %>
produces a bunch of compile time errors in Visual Studio 2008 - although it works fine.
But this seems to be the exact way inline code should be added, at least according to this MS help file:
[URL]
The errors are:
expected expression (at "<%")
expected ';' (at "int i")
expected ')' (at ThumbnailList.Items.Count;
expected ';' (at " i++)")
I have done a
<%@ Page Language="C#" ...
at the top of the file.
As that title says my aspx page shows a compile error on the @Page directive that says "ASP.NET runtime error: Cannot load file or Assembly 'Microsoft.SqlServer.BatchParser' or one of it's dependencies". The project compiles with our error and it runs with no problem. The only real problem that this causes it that the intellisense for anything other than simple HTML is broken so I can't type asp:Controlname and have intellisense show me a the list of items or properties in a control. I get a green squiggly line under all the asp tags saying "Unrecognized tag prefix or device filter 'asp'". This project doesn't directly use SQL SMO but it does reference a project that does. However, I removed that reference and the problem still doesn't go away. I have installed on my development machine the full SQL client and for both SQL 2005 and 2008 (including the SDK) from the Developer editions of both versions. This was not a problem on VS2005 and the project compiles without error in VS2010 too.

I am unsure how should I define my funtion and call it inside my razor view. In the funtion, I will only pass the Datetime variable. It should only return the time in string format.
