Grouping Similar Form Controls

Question

Hi All In my windows form I have 30 rectangles. I want to change the back color of each rectangle when I clicked on it. For that I have write mouse click event for each rectangle. Is there any way to group the controls and use it as a common a name?

Well one thing you can do is to use the same MouseClick eventhandler for all thirty Rectangles. All you need then is a way of telling which Rectangle was clicked. If you've drawn each of them on a Panel say you can use the 'sender' argument to distinguish which Panel and hence which Rectangle has been clicked. If you've drawn them all directly on the form or on some other container you could use the MouseEventArgs argument properties to determine where the click took place and hence which Rectangle was clicked.
