Custom control problem under VS 2005 Beta 2 CF 2.0

[Jen]

Hi,



I have several custom controls that all work correctly when placed on a form
and appear on the toolbox. The problem that I'm seeing is that 2 of the 5
controls disable form inheritance when placed on the base form. If I remove
both of these controls from the base form then my form inheritance works
again and I can see the other controls on the form.



I get the error "Visual inheritance is currently disabled because the base
class references a device-specific component or contains p/invoke" on the
non-base forms at design time.



I have checked and neither of the controls uses p/invoke.



What would a device specific component be? The SIP control? I remarked it
out.



What other things could cause this?



Anyone care to see the code?



These are some of the references.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Text;
using System.Windows.Forms;
using System.Threading;
using Microsoft.WindowsCE.Forms;
using System.Diagnostics;



I also have a reference to "System.Windows.Forms.DataGrid" in the solution
explorer

However i cant add "using System.Windows.Forms.DataGrid" cause i get the
error that it is a type not a namespace.



These 2 controls are the only ones that have a reference to the datagrid
(possible clue)



So if I have a custom control that refers to the datagrid does this kill
form inheritance?



Thanks

UPDATE

I removed my references to the grid control and remarked out all lines using
the grid. Now the custom control works with form inheritance.

However this creates a big problem for me. I need to see the datagrid on
forms that inherit from the base form so i can set table and column styles
at design time

Any ideas what can be done to allow a datagrid on a base form to work with
form inheritance?

Thanks

CLARIFICATION

These are custom controls that reference the datagrid control. If the
references to the datagrid are pulled out of the custom control then form
inheritance works again.

There's good information in this article...

You may need to tag your custom control(s) with the "DesktopCompatible"
attribute.
