create a array of Control and raise events

Question

Hi I am new to VC # and I am stuck as to how to create an array of objects like the treeview programmatically. After I create it programmatically using the new statement how do I write events for it and figure out which index of the control raised the event? treeNB[i] = new System.Windows.Forms.TreeView(); how do I create events for the treeNB object and then use some sort of index property? Thanks a lot for the help. Anirudh

I'd start by giving each TreeView a name corresponding to its index in the array and linking them all up to the same eventhandler like this: for (int i = 0; i { treeNB[i] = new System.Windows.Forms.TreeView(); treeNB[i].Name = treeNB + i.ToString(); treeNB[i].AfterSelect += new TreeviewEventHandler(TreeNB_AfterSelect); } You can then figure out which Treeview caused the event like this: private void TreeNB_AfterSelect(System.Object sender System.Windows.Forms.TreeViewEventArgs e) { TreeView treeNB = (TreeView)sender; int tbIndex = int.Parse(treeNB.Name.Substring(6)); // so treeNB[tbIndex] caused the event // other code }
