Question

I have 84 combo box inside 12 group box in a group of 12. Combo Box are named as cb1cb2cb3cb4cb5cb6...... Group Box are named as gBox1gBox2gBox3gBox4gBox5.... Now I want to save the item name in a variable when I select or change item of any combo box. I know that if I use SelectedIndexChanged for each combo box then I can get what I want I am wondering that is the only way to do.... OR there is any simplified way to achieve the above mentioned purpose. I welcome any suggestion/advice/guidance. Regards to all

You can wire up the SelectedIndexChanged event to the same handler for all 84 comboboxes. You can then determine which one's index has been changed like this: private void cb1_SelectedIndexChanged(object sender System.EventArgs e) { ComboBox cb = (ComboBox)sender; int number = int.Parse(cb.Name.Substring(2)); // etc }
