I am using "NetAdvantage for .NET 2007 Volume 1 CLR 2.0" in a winforms application. I have a simple form which acts a base form for all the forms in the project. It have a ribbon toolbar (UltraToolbarManager) and two UltraButtons.

Whenever I try to open the form from source control a checkout dialog pops up and ask me to check out the form. If i cancel the checkout then the designer of the form displays some error messages.

I think that the designer wants to write something that triggers the checkout dialog. But It does not happened to normal windows forms. I dont know why it happens.

The dereived forms also asks me checkout dialog. If I checkout the forms. then the alignment,size of some of controls are changed. Then I need to rework the alignment and forms.

Is there any way to avoid this?

I have attached a sample project to reporode the problem. "DialogBase" is the base form. "frmAppLogin" is the dereived form.
