c# - Button click should redirect another page based on dropdown selection -

i have form1 textbox , dropdownlist box. when drop downlist selected , click button should redirect form2. have answers redirection of webpage 1 time ddl list item selected not during button click after selection.

kinda unclear on part.

"i have answers redirection of webpage 1 time ddl list item selected not during button click after selection"

if mean display on form2 based on value of dropdownlist form1, can utilize session or request.querystring.

but if mean dropdownlist must have selected value before redirecting form2, can check if has selected value on click event of button.
