    Public Property Angle() As Double
        Get

        End Set
    End Property

See UITypeEditor on MSDN for more information on how to implement a custom edtior.

The UITypeEditor type exposes the virtual PaintValue and GetPaintValueSupported methods that you can override to support the display of a value’s representation.

C#

public class AngleEditor : System.Drawing.Design.UITypeEditor {
    // Override to provide a representation of the property's value.
    public override void PaintValue(System.Drawing.Design.PaintValueEventArgs e) {
        //...
    }
    // Returns whether painting a representation of the property's value is supported.
    public override bool GetPaintValueSupported(System.ComponentModel.ITypeDescriptorContext context) {
        return true;
    }

    //...
}

VB.NET

Public Class AngleEditor
    Inherits System.Drawing.Design.UITypeEditor
    ' Override to provide a representation of the property's value.
    Public Overrides Sub PaintValue(ByVal e As System.Drawing.Design.PaintValueEventArgs)
        '...
    End Sub

    ' Returns whether painting a representation of the property's value is supported.
    Public Overrides Function GetPaintValueSupported(ByVal context As System.ComponentModel.ITypeDescriptorContext) A
        Return True
    End Function

    '...
End Class

To enable the property grid to use the provided representation, set the AllowPaintValue property to true.

C#

propertyGridControl1.OptionsView.AllowPaintValue = true;

VB.NET

PropertyGridControl1.OptionsView.AllowPaintValue = True
