New Post: Customise properties for certain file types

You are welcome, Mike!

1. You should write in you custom project class code like this:

public override FileNode CreateFileNode(ProjectElement item)
    {
      if (item == null)
      {
        throw new ArgumentNullException("item");
      }
      return new YourCustomFileNode(this, item);
    }

2. Inherit YourCustomFileNode class from MPF FileNode class

3. Override NodeProperties creation in custom file node:

protected override NodeProperties CreatePropertiesObject()
    {
      return new YourCustomFileNodeProperties(this);
    }

4. And inherit YourCustomFileNodeProperties from MPF FileNodeProperties class

NOTE: I'm not sure it is correct but I remember right I had problems with custom properties class until I added this property to it:

     [Browsable(false)]
        public string SubType
        {
            get
            {
                return Node.SubType;
            }
            set
            {
                Node.SubType = value;
            }
        }

Hope that saves the time.

Another tip - to understand how to expose properties - look at the implementation of some MPF NodeProperties class inheritors.

Best wishes,
