Could you please provide your dynamic generation of dropdown list.
 
In subject you mentioned validation for text box but in description asking validation for dropdown list.

Solution 1

on the textchange event of dropdownlist control, check whether the dropdownlist selected value is yes, if so display the textbox else dont display it.
Then validate the textbox as,
if (txt1.Visible == true && txt1.Text == "") -- you can validate like this..
 
or you can validate like,
if(dropdownlist.selectvalue == "Yes" && txt1.Text == "")
