Almost all properties of ShapedForm_ are the same as a standard Windows Form. You can use your knowledge of the Form class to customize your ShapedForm. There are two major exceptions:
ShapedForm does not have a title bar, and so does not have maximize, minimize, or close buttons. To get maximize, minimize and close functionality, add a RadTitleBar control to your ShapedForm.
ShapedForm adds a Shape property that can be used to choose preset shapes or allow you to create a new custom shape in the Shape Editor.
Use ThemeName property to set the theme name.
Setting a theme to a ShapedForm
this.ThemeName = "Breeze";
Me.ThemeName = "Breeze"
