c# - Conditional "Browsable" Attribute

Question

Is there a way to make a "Browsable" attribute conditional, so the property that applies it will sometimes appear in the properties page and sometimes not?
thanks :)

I'm not sure this applies to your situation, but you can adjust the "Browsable" decoration at run-time by calling the function below.

/// <summary>
/// Set the Browsable property.
/// NOTE: Be sure to decorate the property with [Browsable(true)]
/// </summary>
/// <param name="PropertyName">Name of the variable</param>
/// <param name="bIsBrowsable">Browsable Value</param>
private void setBrowsableProperty(string strPropertyName, bool bIsBrowsable)
{
    // Get the Descriptor's Properties
    PropertyDescriptor theDescriptor = TypeDescriptor.GetProperties(this.GetType())[strPropertyName];

    // Get the Descriptor's "Browsable" Attribute
    BrowsableAttribute theDescriptorBrowsableAttribute = (BrowsableAttribute)theDescriptor.Attributes[typeof(BrowsableAttribute)];
    FieldInfo isBrowsable = theDescriptorBrowsableAttribute.GetType().GetField("Browsable", BindingFlags.IgnoreCase | BindingFlags.NonPublic | BindingFlags.Instance);

    // Set the Descriptor's "Browsable" Attribute
    isBrowsable.SetValue(theDescriptorBrowsableAttribute, bIsBrowsable);
}
