I'm having a problem with a webusercontrol that contains a button embedded within an editor control. The button has a server side method "Editor_SubmitClicked" but for some reason this definition is not found.

here is the error message:

Error      4      'WebUserControl.ascx.cs' does not contain a definition for 'Editor_SubmitClicked' and no extension method 'Editor_SubmitClicked' accepting a first argument of type 'WebUserControl.ascx.cs' could be found (are you missing a using directive or an assembly reference?)      

Any ideas?

Check if the method call and actual method has same parameter types and same number of parameters and return type

Yes, I pulled this code out of a web form directly where it works with no problem.

<ed:Editor ID="editorQ1" runat="server" Appearance="custom" Height="180" 
 ModeHTML="false" ModeSwitch="false" ShowQuickFormat="false" Width="400"
and code behind ascx:
protected void Editor_SubmitClicked(object sender, EventArgs e)
//update database here...

This is a compile error...where the EditorSubmit_Clicked event in the code behind cannot be found.

I have tags for the editor in the ascx page:

<%@ Control Language="C#" ClassName="WebUserControl.ascx.cs"  %>
<%@ Register Assembly="obout_Editor" Namespace="OboutInc.Editor" TagPrefix="ed" %>

Change ClassName="WebUserControl.ascx.cs"  to CodeBehind="WebUserControl.ascx.vb" Inherits="<yourNamespace>.WebUserControl1"

The below error means that  your compiler is looking for the method in the class "WebUserControl.ascx.cs". I think your class name is not this.
"'WebUserControl.ascx.cs' does not contain a definition for'WebUserControl.ascx.cs' does not contain a definition for"

Your tags attributes are wrong. Follow the steps suggested by ororiole to fix this error
