视觉 Styles 不工作（C# VS2010）

Question

I have a problem with Visual Styles on my WinForm app (.net framework 2) and I fail to find any solution googling for a long time.

The forms in this project look styled in IDE (as should be), but in runtime they appear to be with no styles applied in any OS.

I've tried:

1) Put in my program.cs

        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.DoEvents();

before the form creation and that doesn't help

2) Insert System.Windows.Forms.Application.EnableVisualStyles(); in form constructor.

2) delete, create new manifest that doesn't help either.

After some debugging I found that VisualStyleInformation.IsEnabledByUser is returning FALSE instead of True as it should be. I have very similar application using the same resources and libraries which works absolutely fine, with all styles applied and it is returning TRUE for IsEnabledByUser.

Does anybody have any ideas how to nail it?

Next to all the actions you took, you should also make sure that the FlatStyle property of your controls is set to FlatStyle.System . Check if this true for all your controls, including your Form.
