how to maintian index in collection class -
Hii To all,
I have developed collection class that inherites System.Collections.CollectionBase class and used it to store objects of specific class.
This collection class is attached with array of win forms. Collection idex is mtch with winforms array index. In each form activate event i used one method to get current index of item in my object collection.
When i remove one of the object from list object it will change index of all otehr items automatically. Suppose you remove item at index "0", after removing item at index "1" will become one.
how to get index of item when winform get activated? Because index in collection class is changed.
Please provide any example or link that i can refer. I am trying like anything.
Thanks lot.
