Specifies whether a column type is visible in the System.Windows.Forms.DataGridView designer. This class cannot be inherited.
By default, types derived from System.Windows.Forms.DataGridViewColumn appear in System.Windows.Forms.DataGridView control-specific parts of the Visual Studio designer, but inherit a System.ComponentModel.DesignTimeVisibleAttribute of System.ComponentModel.DesignTimeVisibleAttribute.No to prevent them from appearing in other parts of the designer. This is necessary because the System.Windows.Forms.DataGridViewColumn type implements the System.ComponentModel.IComponent interface, which normally makes an instance of the type appear in the designer.
