Adding dynamic properties to new classes

[Richard Abraham]

I have created a new class ServiceTimer based upon the .NET System.Timers.T imer class. This has a new property CollectionInter valMinutes which I expected to be added to the 'Behavior' section of the class properties and also to be available as a 'Dynamic' property so that I could control it from the application config file. The new property is not shown, but the properties inherited from the base class are

I cannot find any reference to how to do this in the help. I have tried creating the new class as both a standard class and a component class

How should I declare properties in the new class so that they are included in 'Behavior' and ensure they are available as 'Dynamic' properties?

It's perhaps wise to post your property's declaration, so we can see which
attributes you have applied to the property.

Also consider that VS.NET-related issues like the one you're having are more
at home in the vs.net related newsgroups.

Sorry, bit of a newbie here. Not sure which VS newsgroup would be appropriate

My C# code is below, hope that helps

You haven't decorated the property with attributes to make it appear in the
designer. This is perhaps a good article to get started (It's VB.NET, but the
ideas are the same)

Thanks Frans, I have applied the decoration and it now works

Even knowing the answer the documentation on attributes isn't very clear but I'll keep reading it until I understand it
