Multi-line string in a PropertyGrid

Question

Is there a built-in editor for a multi-line string in a PropertyGrid.

Answer 1

I found that System.Design.dll has System.ComponentModel.Design.MultilineStringEditor which can be used as follows:

public class Stuff {     [Editor(typeof(MultilineStringEditor), typeof(UITypeEditor))]     public string MultiLineProperty { get; set; } } 

Answer 2

No, you will need to create what's called a modal UI type editor. You'll need to create a class that inherits from UITypeEditor. This is basically a form that gets shown when you click on the ellipsis button on the right side of the property you are editing.

The only drawback I found, was that I needed to decorate the specific string property with a specific attribute. It's been a while since I had to do that. I got this information from a book by Chris Sells called "Windows Forms Programming in C#"

There's a commercial propertygrid called Smart PropertyGrid.NET by VisualHint.
