Ihave a complex winform in a Visual Studio Team System 2008project. Suddenly when opening the winform in design mode it is displaying the text: To prevent possible data loss before loading the designer, the following errors must be resolved:

Value does not fall within the expected range.

The variable 'navBarControl1' is either undeclared or was never assigned.

The designer breaks in line: this.Controls.Add(this.navBarControl1);

The control is declared:

private DevExpress.XtraNavBar.NavBarControl navBarControl1;

and the control is assigned:

this.navBarControl1 = new DevExpress.XtraNavBar.NavBarControl();

But I have never made any changes to the designer file. What can I do, I have severval days of work if I have to recreate the GUI from the button again. And what about the next timeit crashes?

Looks like a bug to me. You can file bug reports to Microsoft's connect web site and DevExpress's support web site with reproduce steps so they can find out who to blame and who should take action.

I have the same problem, VS 2008, SP1, the program build and execute without problem, but suddenly comes two errors:

The variable 'settingsColors1' is either undeclared or was never assigned.

Object reference not set to an instance of an object.

But the program build and execute.

The project was not changed, any idea? it is not simple to reproduce because comes without a previous action.

Thanks
