i am using VS 2010. while i am double click a button or text box the corresponding event does not generate in code behine file (*.aspx.cs file) rather it is inlined with the .aspx page within the tag <script runat="server">
On a typical form you have some fields and submit button. What event do I use to retrieve the values of the form from the post , process the forms submit?
How can I add page events to the code behind file (.cs file)?
So one of my views refuses to display, instead throwing up an error about an unreferenced assembly in a generated code file.Here's the controller action: [Code]....
And here's the view. [Code]....
And this is the error: CS0012: The type 'System.Data.Objects.DataClasses.EntityObject' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
The error occurs in %appdata%LocalTempTemporary ASP.NET Files oot7045d95d878a2a8App_Web_create.aspx.fd7fb922.zxi-cdky.0.cs, which is clearly not a file I wrote or can edit. System.Data.Entity is referenced in both my view project and domain model project.
I have inherited an ASP.NET/C# project written way back in .NET 1.0. I started programming in .NET 2.0, so some of the antiquated concepts are foreign. I noticed that 80% of the pages have the following snippet or something similar:
#region Component Designer generated code //Required by the Web Services Designer private IContainer components = null; /// <summary> /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// </summary> private void InitializeComponent() { connSQL = new System.Data.SqlClient.SqlConnection(); connSQL.ConnectionString = Inventory.Properties.Settings.Default.connectionString; } /// <summary> /// Clean up any resources being used. /// </summary> protected override void Dispose( bool disposing ) { if(disposing && components != null) { components.Dispose(); } base.Dispose(disposing); } #endregion
Although this area is hit in the page load process, commenting it out has no obvious effects on the web page. I can guess that if the connSQL object is used and not initialized elsewhere, then problems can come up, this just hasn't been the case. So, my question is where does this designer generated code come from? I've never seen in it the code behind. Is this another .net 1.0 thing?
I have version 2.6.10 in my project. I have not modified any of the settings. The generated code is getting updated on build. I added a new method to a controller. It doesn't show up in the Views property. I added new javascript files that don't get added to the Scripts class.
Also, what is the correct method to update to a new version of T4MVC when it comes out. Do I just copy over the existing files in my project?
I have a Solution in which I have A WCF Service web site project which then hosts two separate WCF Service Libraries (each in their own project). One of the Web Services is a Client to the other. When I click the ClientService and select Add Service Reference, it all adds properly, but when I go to build it, I get this error in the reference.cs (the generated file).The type name 'HostWCFService' does not exist in the type 'ClientService.ClientService' C:Users...Reference.cs I don't want it to create a ClientService.HostWCFService namespace, I want to be able to use the HostWCFService as its own namespace. I believe I've had this setup working before at one point; that is, I had this arrangement working before, but am not sure now if the host service was in a sub namespace of the project.
I had a general question about extracting code from a visual studio web test. I used the "generate code" option of a web test and got the following:
[code]....
What I wanted to do is basically put this test into a separate service to run throughout the day for purposes of health checking. I basically want to make sure that users are able to log in throughout the day. What process should I use to get the test into something like a console app? I was running into issues with debugging the webtest code.
My requirement is to catch the event of an HTML tag being generated because of an asp.net server side control. I want to add an attribute in the HTML tag. For e.g. the following asp.net code
In the video here [URL] Joe adds event stubs to his code by selecting them from the drop down in upper right portion of the code window. I can do this in VB, but not C#. Is this feature only available in VB? Is there a setting I must adjust in C#? Is there a way in C# to get a stub for the (for example) OnPreInit event?
I have written a t4 template that basically replaces the work done by StronglyTypedResourceBuilder to give design time access to string resources as properties of classes, one class per resource file. Why? Well I needed to add some customer code that handles string token substitution and a few other customizations. Anyway, the template is working out really well and I may blog on it soon.
In the mean time though, following a common pattern, I have one .resx file for each view, master page, controller, etc. I would really like my t4 template to add a property to each such entity that gives quick access the custom resource class associated with it. For controllers this is easy. T4MVC is ensuring that they are a all declared partial. All I need to do is create the appropriate partial class in my output that declares a readonly property that returns an instance of the appropriate generated resource class.
The Problem:
I would like to do the same thing, inject generated code, into my views. Were this traditional ASP.Net, each .aspx page would have a .aspx.cs page and possibly an .aspx.designer.cs page that are all partial classes extending in the aspx page's class definition. There is no such thing by default in MVC and for good reason. However, I think for my purposes, if there is a way to do this, it would be the way to go.
I could subclass ViewPage and add a generic type parameter and a property that returns the class of that type but that has certain complications. I think adding auto generated code to each view via partial class (that is what partials are for after all) is the way to go.
I have made a basic attempt. I have created a .aspx.cs file for a view and placed a code behind attribute in the page declaration but the class generated from the view seems to reside in a different assembly any my "partial class" ends up as its own class in the same assembly as all my other code.
I am working with a few .Net 4.0 webforms controls such as the Menu control and while I think it's great that I can now declare the way in which controls are rendered (i.e. as either tables or divs), I can't switch off the automagically-included javascript that manages the hover events for those controls, for example:new Sys.WebForms.Menu({ element: 'NavigationMenu', disappearAfter: 500, orientation: 'horizontal', tabIndex: 0, disabled: false }This appears at the bottom of every page that owns such a control.
Two questions. First, is HeaderStyle-Width a preferred/best way to manage column width in a grid view? And second, how do I suppress the genration of the the additional code?
You've probably noticed that when you debug an error which comes from an ASPX or ASCX file (literally, not from a corresponding code-behind file), ASP.NET displays an error page showing you the source file and the line on which the error occurs. The source file being displayed is automatically generated from parsing the page/control. The question is: how can I see this source file without purposely causing an exception?
I'd love to hear that there is some programmatic way (the complexity doesn't matter) to generate source files (preferrably, .cs) from a series of ASPX/ASCX files.
Example. Consider the following ASPX page (the code-behind file may even be absent):
d:DevAspxGenAspxGenDefault.aspx(9,80): error CS0103: The name 'ThereIsNoSuchProperty' does not exist in the current context
This means, theoretically I can open the .CS files passed to the compiler (namely, App_Web_sqj3krv3.0.cs and App_Web_sqj3krv3.1.cs) and see what ASP.NET has generated from my ASPX markup. Trying to rephrase the previous question: how can I obtain this file from an arbitrary ASPX file (assuming that the file is correct and hence no info will be given on where to search)?
what might be best suited to place in the Application_Start and Session_Start subroutines? I know when each subroutine is called. Application_Start when the first user first accesses the web application. Session_Start when a user opens a session with the application. But what code belongs in each of these subroutines. What should the code in each subroutine do?
I am trying to incorporate AJAX in my web project for the first time and it isn't working. I don't know how to instantiate a class once and use AJAX to update the dataset numerous times before updating the database changes using a postback.
My project is to learn AJAX with a class object. Clicking the button is supposed to increment a count by one using a class to store the count. Here is my class:
[Code]....
Here is my HTML code:
[Code]....
And here are my button click event code snippets:
[Code]....
My problem is that as I step through the code (after clicking on the second button) it instantiates a new class object each time which returns a value of 2 every time. I have tried to fix the problem by putting my counter class instantiation in the pageload event using "If Not IsPostBack Then ..." but my probem there is that the button click event block of code would not recognize the cCount class - it put the blue lines under the cCount
My goal is to have the class object available to multiple events in the code behind: especially using AJAX to build records in one of my DataSet tables Does anyone know how to handle this?
is there any tools within VS2008 or Free 3rd Party tools where i can generate a Diagram of Class Methods and Code Behind events. think of the Table Diagram of SQL, it will show all fields, Primary Keys and to what table it is connected via foreign keys, etc.That is what i wish to make, in a much faster way, where it will show all class and within it is all the methods then linking them are the Code behinds and the event where the class is called.
I Simply drag a button from the toolbar onto a new page with a master page and a title, double click it so that I enter the Button1_Click function and sets a breakpoint and add some random code. The breakpoint nor the code never fires. I've tried this on several different pages and controllers, but with the same results: The page reloads, but no code is run. I Have Tried:
Ive tried with three different webbrowsers with all plugins disabled. I've tried to turn of Causes Validation, - Nothing changes. I've tried to clean and Rebuild the project, - Still nothing. I've tried to create a whole new project, -Does'nt work there either. Other Information: A RadioButtonList OnDatabound Event works, but whenever i try to do a Button or ImageButton click event the code for the event never fires. Ive programmed several webapplications in other versions of visual studio and ASP.NET but I have never encountered this problem before.
Breakpoints work in other parts of the code and the compile settings is set to DEBUG.
* Visual Studio 2010 * ASP.NET 4 * MVC 2.
Am I supposed to file a bug report or does anyone out there have a solution?
