Changing the Field of Property Array.

[Anonymous]

Hi,
I have a c++ wrapper which contains an array^ property. When i access it via PropertyGrid, it is displaying something like below.

DValue Double[] Array
[0] 22
[1] 33
[2] 44

But, i want the appearance to be like this.

DValue 22,33,44
A 22
B 33
C 44

I can achieve the Starting part (i.e.)

DValue 22,33,44

with the help of TypeConverter in c#.

But i cannot be able to change the remaining part as above.

Could anyone kindly solve my problem?

Thank you in Advance.

Regards,
Vignesh. S

Your mistake is using double[] to represent 3D coordinates.

That's a very bad design. Arrays are generic which makes it difficult to treat those used to represent 3d coordinates in a special way as you are trying to do.

Instead of using arrays, use Point3d, and provide a TypeConverter for it.

See this file for examples:

Add the file to a C# project, NETLOAD it, and run the sample command. You will see a property grid that shows 2D and 3D coordinates and vectors the way you want.

It is not 3d Coordinates. They are Length values for Different Lines.

Hi Tony,
I actually put A, B, C for not confusing anyone by the X, Y, Z coordinates. But i didnt know that it will misguide you.

Anyhow, I found the Solution for my problem.

It is just by overriding the PropertyDescriptor's DisplayName Property.

Thank you for your Reply.

Regardless of what the values represent, the methods shown
in the example still apply to what you need to do. You can
implement a TypeConverter and apply it to properties of an
object that returns a double[] to present it the same way the
sample code presents 3D points.
