How can “default” values in overridden WinForm controls be prevented?

Question

I\'m trying to learn and grasp what and how C# does things. I\'m historically a Visual Foxpro (VFP) developer, and somewhat spoiled at the years of visual inheritance by cr

Answer 1

Here is a simple solution using the ReadOnlyAttribute in the derived class.

class MyLabel : Label
{
    [ReadOnly(true)]
    public override Font Font
    {
        get { return new Font(FontFamily.GenericMonospace, 10); }
        set { /* do nothing */ }
    }
}

The ReadOnlyAttribute will disable property editing in the VS.NET designer.

Answer 2

Instead of using the "ReadOnlyAttribute", try using the "DefaultValueAttribute" instead. If I remember correctly, the designer shouldn't create code to set the property if the current value matches the value stored in the "DefaultValueAttribute".

Answer 3

Try adding the ReadOnly attribute to the properties of your derived classes:

[ReadOnly(true)]
public override Font Font
{
    get{ // Your Implementation Here }
    set{ // Don't really care,do you? }
}

The ReadOnlyAttribute should enforce the ReadOnly behavior at design time.
