title: Trouble with selected radiobuttonlist value on postback vb.net
body: <p>I have a radio button list on a page that is used to configure products. when the page loads the first time the first list of options is displayed. you select one of them then click a "Next Step" button and the page posts back and shows a new radio button list for step 2. Now if i click a "Previous Step" button i can easily get the previous list of options to display but i can not for some reason get one of the radio buttons to be selected. I can easily bring back the value i need. right after making the radio button list i have a step that just says radiobuttonlist.selected = "somevalue" depending on whatever the user chose when they completed the first step the first time.</p>
  
  <p>when i debug i see that the value is correct and is being applied. but then when the page is displayed the radiobutton is not selected.</p>
  
  <p>I have noticed that when i click my "Previous" button while debugging the folowing steps occur.:</p>
  
  <p>the page.load handler runs and the code inside my if not page.ispostback block does NOT run, which is correct.
  then the handles for the button i just clicked gets run.
  but then after that the page.load handler runs again but this time the code in the if not page.ispostback block DOES run...</p>
  
  <p>is that normal? for the page.onload block to run twice like that on a postback? i think it may have something to do with why my value is not being applied.</p>
