Solution 1

Based upon what little you gave us, I would assume you are trying to look at a dropdown or something like that to get the SelectedValue before the value is selected. This is common when the code for getting the SelectedValue is run when the application or page first loads. You should do a check to be sure something is selected before trying to read the value.
