'Company.Dept.Project.Controls.ControlName' Is Not Allowed Here Because It Does Not Extend Class 'System.Web.UI.UserControl'
Oct 14, 2010
I have defined the following control which serves as a wrapper for another control (simplified code):
[code]....
Can anyone provide any insight as to why it is failing in one environment, but not the others? Is this something related to configuration? The user control is hosted within a "SmartPart" style user control loader which is being used on a WSS 3.0 site in the DIT/SIT/UAT environments.

First off, I am wondering if this is possible. I read slight grumblings around the internet about this, but I was not entirely sure.
My scenario: I have a base chart class which has some methods which all charts should have.
public partial class BaseChart : System.Web.UI.UserControl
{
public BaseChart()
{
}
public void ToggleLegend()
{
Chart1.Legends[0].Enabled = !Chart1.Legends[0].Enabled;
}
}
There is also some mark-up for this BaseChart -- setting background colors, etc. All charts which inherit BaseChart should use this starting mark-up and be able to build upon it.
I would then like to do this:
public partial class HistoricalLineChart : BaseChart
{
public HistoricalLineChart()
: base()
{
public HistoricalLineChart(int reportID)
: base()
{
Chart1.Titles[0].Text = "Hello World";
}
}
where HistoricalLineChart is a web user control with no mark-up e.g. "HistoricalLineChart.ascx"
The problem is that Chart1 is undefined when in HistoricalLineChart's scope. Is there something that I am missing here?

We are using entity framework and we have two projects with two different edmx files. We need to keep both tables in same database and we want to extend funtionalities of one project by the other one. Is there a way to extend edmx files or is there a better solution for this?
we have 3 edmx files in three class libraries.
1.person class library(Core) with core.edmx-Basic details related to a person(name,email ...)
2.CV Claas library with CV.edmx wich have CV related data(Experiance,skills... )
3.Customer Relationship management system(CRM) which have customer data(sales data...)
Then we want to use core class library edmx file(Core.edmx) with cv.edmx (basically cv tables should be able to use tables from core tables) . Same way we want to use the core.edmx with CRM.edmx for the 3 rd project

I'm trying to create a user control class that extends Panel. Essentially, what I want to do is to have a panel that fires off an event whenever it's clicked upon.
So, I create something like this:
[Code]....
And then, in the ClickPanel.ascx.cs file:
[Code]....
I'm not exactly sure whether this would work as I haven't had the opportunity to test it yet.
The problem is that I can't have a class inherit from Panel. Creating a user control class requires that my class extend User Control - at least that's what the error messages have been saying up until now. The problem is that if I do extend it from the base class of UserControl then I lose all the functionality of the Panel itself and the entire thing is rendered pointless.

I like to build a components collection project so that I can use those components later on other projects. For example I created a UserControl called MyDataGrid.ascx
So suppose the projects layout are something like this:
--> IPGostarProject - Under namespace of IPGostar - contains components and lot's of user controls
--> SampleProject - here I want to use MyDataGrid.ascx UserControl from IPGostar namespace.
But as you know LoadControl function only takes virtual directory as it's parameter. So you can't load anything outside the SampleProject directory!

I have an ASP.NET web site project where I am using both VB.Net and C# class files. I have included separate sub folders in the App_Code directory for classes of each language.However, while I can successfully make use of a C# class in a VB class, I cannot do the opposite: use a a VB class in a C# class.
So, to illustrate, I might have two classes such as this:
Public Class VBTestClass
Public Sub New()
End Sub [code]....
I get an error that "the type or namespace "VBTestClass" could not be found". What am I missing here?

public class foo : System.Web.UI.Control
{
public foo()
{
var a = new HyperLink(){ Text="Test", NavigateUrl="~/abc.aspx"};
this.Controls.Add(a);
}
}
The above code works properly, and when added to a page will successfully identify the tilde / ~ symbol and convert the url into a relative url.
However, when I change the derivation of the class to System.Web.UI.WebControl it does absolutely nothing, and leaves the tilde / ~ intact.
I had a look at System.Web.UI.Control which implements the IUrlResolutionService interface, but still can't seem to get System.Web.UI.WebControl to resolve urls.

My ultimate goal is to create a UserControl in a class in my App_Code folder and render the html from that into a string.
The rending of HTML can be done using this example I believe:
How do I get the HTML output of a UserControl in .NET (C#)?
My Question:
I created my user control
public partial class Controls_MyUserControl : System.Web.UI.UserControl
I've registered it in my web.config
<add tagPrefix="UC" src="~/Controls/MyUserControl.ascx" tagName="MyUserControl" />
I can reference this on a page just fine
<UC:MyUserControl ID="MyUserControl1" runat="server" />
Yet when I try to create an object of this control type in a class (in my app_code folder) it doesn't allow me.
Controls_MyUserControl dummy = new Controls_MyUserControl();
The potentially strange thing is when I put this code into a code behind of a page, it works.
what I need to do to have the usercontrol to be able to be created in my class in the app_code folder?
My guess is, is that I need to reference the control in a "using" statement at the top, but I'm not sure what that'd be.
It's not in a namespace to my knowledge (at least there's no namespace, in the code behind of the actually user controls). Though I'm not sure if it inherits one from the System.Web.UI.UserControl.

I am using Visual Studio 2008 with .Net 2.0
I am maintaining and old application in ASP.Net and it has one CustomGridView control with 4000 lines of code. I see that in that file only, when I try to modify any code the IDE does not respond quickly as it does for other files. I thought of creating partial classes for the same but it seems that VS is not reconginzing the new partial class. I am trying to use the variables from the old partial class and it is not able to reconize any variable or method.

I have an asp.net usercontrol (ascx) that inherits from an abstract class (that inherits from a UserControl). My Project is in a 3-tier architecture (DAL -> Bll -> UI/Views). Currently there are no class files in the UI layer (other than the code-behinds). Which layer should I add this abstract class to?

I just had some issues with my computer. I ran system restore a few times and it fixed the issues. The technician at the PC repair place said he didn't know what caused it but that it was most likely an issue with the registry. System restore seems to have fixed my pc because now it runs correctly.
This created an issue with a project that I was working on in VS 2008. When I started VS it gave me a message that it was configuring itself, because this was the first time it had been run. This makes sense with what the guy told me about running system restore.
The issue is that the project I was last working on has a bunch of errors now. It had none before the PC issue but it now has 24. They pertain to the aspx.cs and the aspx.designer.cs files. They all have the same basic error which is:
Error 1
