One by one combobox's item. Possible or not with c#?

Question

Hi!

 

I am in big need. I have three (3) items in my combobox:

"morning"

"afternoon"

"good night"

 

When I use this code:  comboBox1.SelectedIndex = 1;

Its displaying me the first item. Means if I write comboBox1.SelectedIndex = 2 or comboBox1.SelectedIndex = 3;  Its will display the second or the third one. This is normal. But there is a problem. I need to display each item one by one automatically with a interval of 1 second each when I click to a button.

 

Hope to be well understood. Thank you,

Israel.
