Hi,
for go to next question u have put one button or linkbutton in a gridview.
so call a gridview rowcommand event .

in a linkbutton or button set a command name or command argument.
in a command argument bind your question id and on row command event get the question id value and pass to the database and get related right answer.
now find a four radiobutton control from a gridview and check the right answer with radiobutton answer.

For Example:-

<asp:Button ID="Button1" runat="server" Text="Next" CommandArgument='<%# Eval("QuestionID") %>' CommandName="Next" />

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
      if (e.CommandName == "Next")
      {
        int question_id = Convert.ToInt32(e.CommandArgument.ToString());
        //now pass this question_id value to the database and get the right answer
       //after that find radio button control
      }
    }

Let Me know
Regards,

Harsh Shah
