Suppose I want to remove page validation on an exam to let the page automatically update the datasource based on a timer. The problem here is that some users may not have answered all questions before the page updates. This will result in some of the Radiobutton.selecteditem.text/values being returned as blank. This is the problem. I am getting the error cannot be set to null object.
Is there a way of selecting all the remaining questions automatically from a radiolist? (with the Incorrect answer)
The datavaluefield is what contains the correct or Incorrect values.
Im using VB.NET
