I have 84 combo box inside 12 group box, in a group of 12. Combo Box are named as cb1,cb2,cb3,cb4,cb5,cb6,...... Group Box are named as gBox1,gBox2,gBox3,gBox4,gBox5,.... 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

"84 combo box", you have design issue not a combobox issue
"SelectedIndexChanged for each combo box", why don't you use the same event handler for all of the comboboxes?

Solution 1

Try:

C#

private void myComboBox_SelectedIndexChanged(object sender, EventArgs e)
    {
    ComboBox cb = sender as ComboBox;
    if (cb != null)
        {
        ...
        }
    }

Thank you for your guidance.. But I am bit confused about your code. What does myComboBox represent in your code. If it the name of one of the combo box out of 84 combo boxes then how the problem is solved?

No, you point all of the comboboxes at the same event handler method.
When the event fires, the same handler routine is called, with the ComboBox that had the selection change passed through as the sender parameter.
The code converts the sender to a ComboBox, and you can then use "cb" as if it was the name of the ComboBox on your form.

Try it! You'll see what I mean...
