Set The Inherits Attribute Of An ASPX Page Directive To A Class In An Arbitrary Assembly?

Feb 24, 2011

Is it possible to set the Inherits attribute of an ASPX Page directive to a class in an arbitrary assembly?

I need to modify an ASP.NET (1.1) application for which the source code was lost. In a new assembly (foo2.dll) I've created a replacement code-behind class that derives from the original class in the site's code-behind assembly (foo.dll). It seems easy enough to set the Inherits attribute of the Page directive to the new class name, but when I do that the web server gives me Could not load type 'Foo2.checkout2'. I am referencing the new assembly in the <assemblies> section of Web.config.

I don't see anything in the documentation to indicate that this scenario is unsupported, but I'm not certain that it is, either.

Original

<%@ Page Inherits="Foo.checkout" language="c#" Codebehind="checkout.aspx.cs" AutoEventWireup="false" %>

New

<%@ Page Inherits="Foo2.checkout2" CodeFile="checkout2.aspx.cs" CodeFileBaseClass="Foo.checkout" language="c#" Codebehind="checkout.aspx.cs" AutoEventWireup="false" %>

Creating A Template Item From A Web Form And Auto Generating The Inherits Page Directive?

Jan 27, 2010

OK, so I'm trying to create a template item from a web form.

I have referenced this article: [URL] and it exports the template and installs it fine.

When you try and use the template item within a project though it leaves the inherits="_Default" in the page directive like shown below:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="FormTemplateDev.aspx.cs" Inherits="_Default" %>

So it thinks all the new template items use the original form name pre-template generation. This is an issue in the code behind too as shown here:

public partial class _Default : System.Web.UI.Page

I have seen example of passing paramater strings through but havent managed to get anything to compile. I found something like below:

public partial class $safeitemname$ : System.Web.UI.Page

This was the link to the list of available template parameters i found:

Specificying A Page Directive Attribute On A NHaml Page?

Apr 11, 2010

I am working on an MVC site using NHaml for the view engine.

I have a page that needs to submit HTML code as a form value and am getting the System.Web.HttpRequestValidationException thrown at me.

I want to specify the <%@ Page validateRequest="false" %> so that this page will allow this data to be submitted but am unsure on how to do this with NHaml generating the pages.

The editor I was using was TinyMCE and I found that it has an option for encoding the output, that way it doesn't trigger the anti-html validation.

Mvc Views With CLR Generics Syntax In Inherits Attribute?

Oct 18, 2010

For reasons I won't go into I need to use CLR generics syntax in an ASP.NET MVC view.

I.E. NOT this:

System.Web.Mvc.ViewUserControl<someobject>

but this:

System.Web.Mvc.ViewUserControl`1[[someobject]]

When I run the application I get

Parser Error: could not load type `System.Web.Mvc.ViewUserControl`1[[someobject]]

How Does One Output Arbitrary Text From INSIDE A Control Class In C#, MVC

Aug 28, 2010

Is it possible to say something to the effect of 'SomeClass.Out.WriteLine("hello world")' and have it actually show up for the browser to render? I ask, because I notice that the HtmlHelper BeginForm implements IDisposible. So at the end of the using block, a closing tag is written to the browser.I am not saying I would use this practice, as it seems like a bad idea, but I just want a better understanding of what is going on under the hood of C# ASP MVC.

How To Create A Custom Class That Inherits From System

Apr 22, 2010

I wanted to create a custom class that inherits from System.Exception and adds a few properties and methods specific to the project.

The issue I'm seeing is that a standard try/catch block catches generic Exception class and the compiler thinks that converting that to my custom class is OK. However, at runtime if the actual error is something else like a a System.Net.WebException for instance, then at runtime it will not convert to my custom class. Then my own error catch throws an InvalidCastException.

Obviously the one thing I don't want to happen is to have my error logging methods throw errors on their own...

So, how can I convert ANY exception to something that my custom class can use?

Here's a code example:

Csharp Code:

[code]....

Now, this code builds just fine... VS2008 and VS2010 have no issue with converting an "Exception" to "MyErrorClass", but at runtime it certainly doesn't like converting a "WebException" to "MyErrorClass"...

Why Can't Use C# Syntax In Inherits Attribute For A Closed Generic But CLR Syntax Is Fine

Jan 15, 2011

The following CLR syntax works fine in my aspx page:

<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="Website.MyBasePage`1[HomePageViewModel]" %>

But this C# syntax does not:

<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="Website.MyBasePage<HomePageViewModel>" %>

Note, I am not using ASP.NET MVC, but this works fine if using System.Web.Mvc.ViewPage<> from ASP.NET MVC.
My MyBasePage looks like this:

public class MyBasePage<TModel> : Page where TModel : class {
public TModel Model
{
get { return (TModel)HttpContext.Current.Items["model"]; }
}
}

Error About "Inherits" Attribute Even Though It's Correct?

Sep 23, 2010

Having a really strange issue at the moment with an ASP.NET site I'm currently building. At the moment, I'm writting the HTML and CSS for a page called Dashboard.aspx. But when I go to view the page in a browser, half the time it throws up this error: ASPNET: Make sure that the class defined in this code file matches the 'inherits' attribute, and that it extends the correct base class (e.g. Page or UserControl). I've checked the Inherits attribute on the .aspx page, and it matches the Partial Class held in the VB code of Dashboard.aspx.vb file.

When I refresh, it will always come up with this error. Then after a minute or two, it will load fine with no problems. I had a quick look on Google and I couldn't find an answer to this issue. I have also changed the name of the partial class (and the content placeholder on the .aspx file, thinking that may have caused a conflict) and nothing I do seems to fix it. Could anyone shed any light on what's going on?

Custom Server Controls :: Composite Control Which Contains Arbitrary Content Defined In .aspx Of Parent And Thier ViewState

I want to write own control which can contain other. And I want to define content of the control in the .aspx file where the control is defined. I have written such control.

The following samle illustrates the issue: I defined two asp:DropDownList ID="ddl1" and ID="ddl2" One of them is inside of my control and other is outside.

Security :: Built-in Membership Framework And Has Implemented Own Provider By Creating A Class That Inherits From MembershipProvider?

Jan 23, 2011

used the built-in Membership framework and has implemented his own provider by creating a class that inherits from MembershipProvider (found in System.Web.Security). I actually went ahead and created a custom provider which inherits from MembershipProvider. The problem is that there are several methods I do not really need. Also, the schema is totally different. Plus, most methods return a MembershipUser which means my User class has to inherit from it as well. So really, what benefits does the MembershipProvider and the whole Membership framework add to my system? Do these benefits justify the fact that I won't be using most of the methods on the class?

MVC :: Arbitrary Input Fields On Page

Oct 23, 2010

I am looking for some adivce about the possbility of doing the following while working whith MVC. Firstly sorry if the subject line is not very descriptive. I have put something together in ASP WebForms where by I can put a few core fields on my page that identify an object, e.g. a Name and ID... and then I can add arbritrary fields to the aspx page that are now saved and retrieved with the "owning object". These extra fields are stored in a seperate table on the database to the primary object fields. A short explanation of how this works:

1. I have my own version of TextBox (and other input controls) called r3d:TextBox (etc.) and this text box has XmlParent and XmlElement tags, this is done by way of an interface.

2. I have a r3dBase page that all my forms inherit from and this page check for the existstance of any r3d:TextBox (and other input controls) that have the XmlParen and XmlElement tag defiened.

3. When an iheriting form is saved the controls with the Xml tags defined are also saved, but I don't have to change any code in the code behind pages. The framework I have put in place takes care of this for me. The data is saved

4. When an inheriting page is loaded all controls with the XmlParent and XmlElement tags are populated with any data that has previously been saved for them that belong to the main object being displayed on the page.

This provides for a nice easy way for me to extend my forms with non core data when clients request new fields. It also means that different clients can request different new fields and I don't have to make any modifications to the core objects. I have another mechanism that determins what fields are seen by which clients.

Anyway I am completely new to MVC (not written a single line of code) so I have no idea as to whether this paradigm will lend itself to the above described mechanisms or not. Does any one have anythoughts about this, approaches I might try to achive the above to of functionality or perhaps completely different suggestions that would achive a similar end that might work well with MVC

What Is A Page Directive

Oct 10, 2010

I'm studying up for a Microsoft Certification exam, and some of the wording for the 'content' in the examn confused me. In the MS exam website, under Developing Web Form Pages, it says in regard to the content on the exam...

This objective may include but is not limited to: page directives such as ViewState, request validation, event validation, MasterPageFile; ClientIDMode;

I was under the impression that a page directive referred to the @Page keyword, and the associated values defined in the @Page section were attributes/properties. But the wording of the exam content almost implies that the attributes/properties of the @Page keyword are directives.

Put 4 Links In The Sidebar Of Master Page Which Every Other Form (content Page) In Web Application Inherits - C# / Visual Studio 2008

Apr 3, 2011

I want to have 4 links in the sidebar of master page which every other form (content page) in my web application inherits.

<table>
<tr>
<td width= "150px">
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
<asp:Menu runat="server" ID="MainMenu1" CssClass="MasterContent" StaticSubMenuIndent="30px">
<Items>
<asp:MenuItem Text="My Software" NavigateUrl="~/MySoftware.aspx"></asp:MenuItem>
<asp:MenuItem Text="Check Out" NavigateUrl="~/CheckOut.aspx"></asp:MenuItem>
<asp:MenuItem Text="View Shopping Cart" NavigateUrl="~/ShoppingCart.aspx"></asp:MenuItem>
<asp:MenuItem Text="Continue Shopping" NavigateUrl="~/Start.aspx"></asp:MenuItem>
</Items>
</asp:Menu>
</asp:ContentPlaceHolder>
</td>
<td width="900px">
<asp:ContentPlaceHolder ID="ContentPlaceHolder2" runat="server">
</asp:ContentPlaceHolder>
</td>
</tr>
</table>

This is the content in the master page as you can see there are 4 menu items i tried to form as sidebar and i tried to inherit in home.aspx(one of the content pages) as follows:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Start.aspx.cs" Inherits="WebStore._Start"
MasterPageFile="~/Webstore.Master" %>
<asp:Content ID="StartSideBar" runat="server" ContentPlaceHolderID="ContentPlaceHolder1">

But unfortunately the sidebar is not at all getting displayed. I know i'm doing fundamentally wrong some where. My intention is to have web pages to have sidebar like this. It is a screenshot of my intended page.

Web Forms :: Tilde For Master Page In Page Directive Not Working?

Mar 13, 2010

I am receiving a Parser Error with all my pages in a particular folder:

Parser Error Message:

The file '/railroad/freightcars/covered_hopper/MasterFiles/Freightcars.master' does not exist.
Line 1: <%@ Page Title="Freight Car Photos - CP Covered hoppers - CoveredHopperPhotos.com" Language="C#"
MasterPageFile="~/MasterFiles/Freightcars.master" AutoEventWireup="true" CodeFile="cprail.aspx.cs" Inherits="railroad_freightcars_covered_hoppers_cprail" %>

It seems like the ~ is not resolving; none of my .aspx pages in this folder work. All my pages in several other folders work fine.

I had this problem with another folder when i first published pages to a folder named covered_hoppers. Since i couldn't figure out the problem, i renamed the folder to covered_hopper and re-published.. all worked fine for a couple of months until yesterday. Now i am having the same problem. No problems on my local copy; never had this error with any other folder in my site.

Access Static Class Properties From Aspx Page?

I am on .aspx page and i want to take the width and height of a control from a static class
where i have defined them as constans.

Is there any way to access that class directly from the aspx page?

I know that i can make a method like:

width="<%= getWidthSize() %>"

and inside the aspx.cs to define this method to take the size from that static class.

But i am asking if this could be directly managed from the web aspx page...?
