New Post: Dynamic attribute to change DescriptionAttribute in PropertyGrid of CollectionEditor

I am using attributes to define the Description, Category and Display name of properties that populate a PropertyGrid (within a CollectionEditor).

Is there any way to modify these attributes at run time such that they display different values? For instance, one of my properties is Temperature, for which I would like the Description to display "Enter temperature (°C)" if the user has selected one unit system and "Enter temperature (°F)" if a different unit system is selected.

Code for the property is shown below:

<DescriptionAttribute("Enter temperature (°C)."), _
         CategoryAttribute("Physical properties"), _
         DisplayName("Temperature")>
        Property Temperature As Double
            Get
                Return myTemperature
            End Get
            Set(ByVal value As Double)
                myTemperature = value
            End Set
        End Property

If I try and put a variable in the argument to DescriptionAttribute I get a 'Constant expression is required' error.

If this is not possible, is there another way of achieving the same effect?

Many thanks for any help.
