Composite UserControl & ArrowKeys

[Toby Twerl]

I have designed a Composite UserControl that is similar to a ToolStrip but without all the Bells & Whistles and with the buttons behaving in the fashion of "RadioButtons"

 

The Parent Control inherits from a "ContainerControl" and the Button from a UserControl.

 

Everything works fine using the mouse for navigation and Button selection:

MouseUp

MouseDown

MouseEnter

MouseLeave

MouseMove

Etc

 

I am now trying to navigate by means of the Keyboard and have arrived at a complete mental block.

 

I have investigated "ProcessCmdKey" and "SelectNextControl" only to have my code evolving, more and more, into the proverbial spaghetti type.

 

So far all I have managed is to trap the "Enter" key (by way of code in the Button Control) but then only when the Button is first selected by the mouse.

 

All I need is to focus each button, in turn, backward and forward by means of the Left and Right ArrowKeys and, as a retired Machine Designer, to achieve this in an elegantly simple manner. This was quite simple in VB6 where we had Control Arrays.

 

I am only a recreational programmer who enjoys the challenge and, as I said retired, so there is no urgency to this problem - I'd just like to resolve it before the "Grim Reaper" comes a-knock'n.

 

Thanks,

Toby T.
