Inherited Layout Issues

So I have in my application a form that I use as a base form.

It has a panel docked to the top, inside which it has a panel docked to the top to hold the windows title and a panel set to fill to hold a window toolbar.
There are a few other sub panels and controls inside these 2 panels, labels, text boxes, buttons etc.

I then have another form that inherits from this.
In the designer I can see the inherited controls, but they don’t all appear. Worse still at runtime the top panel that holds the window title is not the correct size, it is somewhat shorter in the y plane.

If I modify things in the base class it seems erratic if it updates the inherited form at all or correctly. One example being where I deleted a panel in the base form, yet the inherited form still had a SetChildIndex call in the .designer.cs referencing it which I had to remove manually.

We are about to migrate a substantial application currently in Visual WebGUI to Wisej, and in order to maintain a consistent layout and style throughout I need to have base controls and forms that inherit their layouts correctly, and any changes made to the base forms ripple through properly.

Can you help at all with this ?
Is it something you are aware of and are improving ?

Thanks,
