Hello Rohan,

you should explain what you are trying to do exactly, because in your
code sample, you have no collection at all and you apply
CollectionConverter (which is not an editor btw) to a property of type
CC_Collection which is a simple class containing a color and a string.

Hi VisualHint,

Hi,

So what I want to do is to use the collection editor in the property
gird for fill a collection that contains Name and color in this case.

You can see here in this example that I have a structure that contains
name and color. And the when I use the Add function it adds the
appropriate information in to the mynewcolor array which and contain
up to 10 elements. For this is work I a form that contains textbox and
a button, so the user can enter and text then pick a color and then
press ADD. I am already using a the propertygird, I can implement a
collection that would allow me to do this!



Public Structure Mycolors
Dim CName As String
Dim MyColor As Color
End Structure

Dim mynewcolor(10) As Mycolors
Dim i as Integer =0

Public Sub Add(ByVal name As String, ByVal xColor As Color)
mynewcolor(i).CName = name
mynewcolor(i).MyColor = xColor
i=i+1
End Sub


I hope you do understand

Thank you

Rohan,

well, if I had to explain you how to do it, I would tell you what is
in the article you are mentioning. If you tried to follow it, you are
not explaining for what you experience some difficulties. It involves
TypeDescriptors, TypeConverters and custom PropertyDescriptors.

Other than that I see that you are using a structure for your name/
color pair. You can do it, but be aware that it will add an additional
constraint to your code. The grid won't be able to edit it directly
and you will need a TypeConverter that supports the CreateInstance
method. Use a class if you want to avoid that.
