C# .Net: button OnClick event not being recognized

[chronic malfeasance]

Hello,

I have a C# .Net 2.0 project. Every single page with a button that contains an OnClick method receives a Compilation Error on run stating the definition for the OnClick method does not exist. Here is an example of one of the pages:

<asp:Button ID="cmdRunXMLValidation" runat="server" Text="Run XML Validation" OnClick="cmdRunXMLValidation_Click"></asp:Button>

back-end:

protected void cmdRunXMLValidation_Click(object sender, System.EventArgs e)
{
//stuff
}

and it recieves this error:
'ASP.xmlvalidationprojectsnew_xmlvalidmain_aspx' does not contain a definition for 'cmdRunXMLValidation_Click'

I have had this problem before when using a .NET 1.1 project because the OnClick events weren't properly defined in the InitializeComponent() method, but I was pretty sure I don't need to define such things in 2.0, is this correct? Any ideas?

Thanks,
Callie

Do the tops of both the aspx and aspx.cs files have mathcing names and such?

For example

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

And

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

Yes they do:

<%@ Page Language="C#" MasterPageFile="~/MasterPages/Main.Master" AutoEventWireup="true" CodeBehind="XmlValidMain.aspx.cs"
Inherits="PrintingEngine.XMLValidationProjectsNew. XmlValidMain" Title="Synet Media - XML Validate"%>

and

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

I think even the inherits has to match

But the 'inherits' declaration is the correct namespace of the file. If I change it to just 'XmlValidMain' I get the following error:

Parser Error Message: Could not load type 'XmlValidMain'.

Source Error:
Line 1: <%@ Page Language="C#" MasterPageFile="~/MasterPages/Main.Master" AutoEventWireup="true" CodeBehind="XmlValidMain.aspx.cs"
Line 2: Inherits="XmlValidMain" Title="Synet Media - XML Validate"%>
Line 3:

This may be part of it: this project initially contained Page_Init and InitializeComponent() methods and I removed them and added the OnClick declarations to the button objects instead. Does anthing else need to be changed for that to work?

Is this a .net1.1 web application?
I've never had access to my page_init() and the InitializeComponent() functions in any of my .net2.0 web projects.

[chronic malfeasance]

No it's a 2.0 application. Me either that's why I was surprised to see those methods in the code. I think possibly someone before me upgraded from 1.1 to 2.0 and that is why the methods existed.

Could you just re-make the file from scratch?
i.e. delete them and then re-add them and copy/paste the contents back in?
That works a lot more frequently then it should
