Dynamic Controls...how to ID?

[doogman]

I have wrote my own icon class that places a bmp and two lines of text onto
a panel. These icons's are created dynamically and represent positions on a
map. I want to be able to click on the icon and use the icon as an index to
the data it represents. IE. click on it using a contextmenu and be able to
edit, move, and delete the icon.

I am able to actually put it on screen, add the contextmenu and select its
events, but my question is how do I know what the ControlNo is for the icon
I am selecting in the panelField.Controls list?

Should I create an array to store these controls in? And again how would I
be able to extract the Icon no in the ArrayList so that I can delete it
from the array, etc.? Basically touch that specific icon object in the
heap...

Thanks as always peoples....

One of the solutions would be to store data in the Hastable using the Icon
as a key. Underneath the Hastable uses object address in memory, so this
gives you reasonably fast binary search. The Hashatble items will be the
objects associated with icons
