From javascript or code-behind? If you are looking for code behind, then use SelectedIndex_Changed event of dropdown and use,
ddl.SelectedItem.TextArun Jacob http://codepronet.blogspot.com/

For server side, as suggested use SelectedIndexChanged event.. For client side, add the onchange attribute to the dropdown where in the javascript use this onchange to set the textbox value (assign the value that is selected in dropdown)
