Control Arrays

dotnet compact framework:

More of a CLR issue, but WHY ON EARTH did they remove Control Arrays?

For example, in VB6, if u were making a dialog similar to the standard section of the Color Common Dialog, u'd have an array of PictureBoxes with different back-colours, and clicking on them would raise a single, common event:

Private Sub picColours_Click(Index as Integer)

MyChosenColour = picColours(Index).BackColor

End Sub

What could be more logical? It is...
- economic on code (no need to write practically identical event handlers for every single object)
- allows you to view-and-edit the objects in the form designer

Whereas now in VB.NET, you'd have to...
- create a object array
- create those objects dynamically at run-time (no ability to edit at design-time)
- put an AddHandler statement in Form_Load for every single one of those controls!

Fine, if you go into Add\Remove Toolbox Items, there is are things like "LabelArray" and "ButtonArray" - but how on earth are you supposed to use them?

Not sure if you are aware but choose to ignore the declarative way of
handling events in VB so I'll point it out:

You could create a subroutine that handles more than one event by adding a
comma-separated list of events, like so:
Handles txtOne.KeyPress, txtTwo.KeyPress
making a cheap replacement for Visual Basic's control array feature (which
..NET doesn't support).
