Implementing Interface In An Aspx Page?
Feb 8, 2010
for reasons beyond the scope of this discussion (say xcopy an aspx page to a directory, so that we dont have to get a new build out) , we would like to implement an interface in an aspx page.Say, if the page is myPage.aspx, it is usually your class in the codebehind mypage.aspx.cs which implements the interface. When I do something like this
<%@ Page Language="C#" AutoEventWireup="true" Inherits="ICustomInterface" %>
I get an error
Parser Error Message: 'ICustomInterface' is not allowed here because it does not extend class 'System.Web.UI.Page'.
How ever, when not specifying an Inherits attribute the page does not throw an error. So by default, when we do not specify an Inherits attribute, the page inherits from System.web.UI.Page ?
We are using VS2008 web application project and are not precompiling the aspx pages. We would like to intercept the request to this page in the HTTPModule (begin request) and if the request is to a page of type ICustomInterface we would like to process it differently.

We have a WebForms Control which requires that the ID of another Control implementing ITextControl is provided.What exception should we throw if there is no control with that ID or a control is found but it's not implementing the interface?
[code]...
Should we split it into two cases and throw one exception if there is no control with that ID, and another one if said control does not implement ITextControl?If so,which exceptions should we use then?

I have a hierarchy in my website project as below:
[CustomControl1 - folder]
- CustomControl1.ascx
- CustomControl1.css
- CustomControl1.js
I load css and js files dynamicaly based on which controls are used on particular page. I am doing it by using following code:
[code]....
where AddLinks method adds HtmlLink controls to Page.Header with href attribute set to coresponding css and/or js file.
I would like to add Interface that would force new controls to have AddLinks method but it is impossible since it is a static method. Because my custom controls inherit from Control class I cannot use abstract class and/or virtual methods either. How can I achieve my goal?

Got a little dilemma I could use some guidance on. I'm trying to call an Interface method that resides in my Business Layer from within the template of a gridview in the same manner as below:
<%# GetEmployee(Eval("EmpId"))%>
i.e. it reads as follows:
<%# BusinessLayer.IEmployee.GetEmployee(Eval("EmpId"))%>
I'm actually getting the following error:
"An object reference is required for the non-static field, method, or property"
Which makes sense as I haven't instantiated as instance of the Interface. So the queston is how do I do it?

I'm building an n-tier application, with the web client and the class library separate. I'm also using the factory pattern of development, using interfaces to act as containers for different objects they are associated with. The problem I'm expreriencing is that I declared a public interface class in the class library and I can create an instance of it in in my aspx pages but whenever I declare it in my custom control code-side, i get an error, like so:
Error 20 The type or namespace name 'IContentMaker' could not be found (are you missing a using directive or an assembly reference?)
notge that I have inherited the class library namespace using the 'using' keyword just in case you are wondering. My code is like so:
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using TQO_Classes ; //importing the class library project
public partial class PageContentMgr : System.Web.UI.UserControl
{
private IContentMaker _data; //this line throws the error, it works fine on aspx pages

I am using URL Routing in my .Net Web Application. I would like to prevent users from being able to access the .aspx page.
Example:
Actual URL - [URL]
Routed URL - [URL]
I want users to be able to access the page only by going to /Testimonials, but I would like to setup /Testimonials.aspx to redirect to its route at /Testimonials.
Is there an easy way to do this for Routed Pages throughout the application?

I am working on a asp.net reporting project using crystal reports. I am a little new to working on making the project dynamic or reducing down code.
I have many aspx pages which are using the same logic of collecting input from textboxes and inputing to business logic layer.
I was thinking if someone can suggest me inheritance and interface/abstract method to be implemented on muliple aspx pages?

I have a page which gives user to generate report based on different filters selected. my thoughts Loop through each filter control (checkbox, multi select list, radiobox list) and build dynamic where conditions and conjunctions for each filter and then run query Get all the data (i think this will causes an overload with all 4-5 tables joined) and then use Linq to filter this data based on user selection Is there a better way to implement this?

I have an ASP.Net website and I want to use a custom error page. I put the following code in my web.config
<customErrors mode="On" defaultRedirect="~/error.aspx">
<error statusCode="404" redirect="~/error.aspx" />
</customErrors>
The problem is when i go to a URL that does not exist is still uses the 404 error page specified in IIS Manager.Question: How can I make it use the error.aspx page I have created? Why do the settings in IIS Manager override the web.config?

I have a site with about 4 pages or so. I was asked to implement a very simple security (check if user in database, if not kick out) using active directory and validating against a table of users. I was simply thinking of createing a master page and making all pages inherit that master page. I would then authenticate the users from the master page.

I wrote a test page that does a bunch of busy work in a method called at page load. This process as I have it now takes around 12 seconds.
If I try to load another page while the first long running page is loading, this second page doing nothing except writing out a world, it doesn't load until the first long running page is finished.
Why is this the case? I would think IIS would be able to handle multiple concurrent connections, it seems crazy that one long running page would stop every other page in the application from loading. I must be missing something or not understand how IIS works.
I would think multiple independent requests would be spawned on different threads. Is this only the case if the requests are from different sessions entirely? Are all requests from a single session bound to a single thread?

I work in VS 2008. Whenver I add a server control(Label) and set it properties in aspx.vb and build the solution, I get the error "Label1 not declared". While analyzing this issue I noticed that the event handler statements for the Label1 where not added in the designer.asp.vb file. These statement would actually be added automatically when I drag and drop a control to my webpage.
I would also like to inform the scenario after which this problem came to me. I was working in VS 2008 , VS 2005 and VS 2003 in the same machine.Could this have caused the issue ?
Now each and everytime when I add a control, I am adding the "With Events" code in the designer page to make my build succesfull which makes me to spend more efforts.
