Is there a way to display and edit values in the PropertyGrid (and his CollectionEditor) of an object, which is derived from an abstract generic class? I don't get the properties displayed only something like this: "IFilter´1" or "BaseFilter'1" Where IFilter is an Interface, and BaseFilter an abstract class. All objects contained by thi...
Okay, I've read a couple of questions regarding the use of the PropertyGrid and collections. But, I'm having a difficult time understanding how/if [TypeConverter] will work for me. I've read the little blurb-age that MSDN puts out there, and frankly, it's a bit lacking to this poor, self-taught programmer. So, here is what I have. First...

Hi All, I have a FileNameEditor inside a property grid, which has a few entries like Main File : "C:\blah1" Sec File: "C:\blah2" and so on. My problem is that I cannot copy and paste from one property entry to another, and I cannot type in the fields manually as well. Is there a specific property that will enable editing inside the...
I had a strange problem editing a class in the property grid whereby the property grid would refresh incorrectly. I managed to reduce the problem down to a class with just two properties. I've included the code at the end to ease explanation. It basically boils down to a class with two properties. The first of which is expandable (a fo...
I have a custom collection, lets says COL, that derives from ObjectModel.Collection. I have my own collection editor that works fine when a property, of type COL, is Read and Write enabled. However, if I change the property to ReadOnly, the open editor button stops showing in the property grid. As a test, I override my custom editor wi...
I'm using a PropertyGrid in an application I am writing to allow users to view and sometimes edit instances of my objects. Sometimes the user may have a file open in read/write mode where they can make changes to the file through the property grid.

Hi, I'm looking to hide/show properties depending on what selection the user makes in a drop. I am handling the event fine, but cannot actually make the correct properties disappear. The solutions I have found on line are mainly from 2005 and as I've had very little experience with it I thought I must be doing something wrong if hiding ...
