The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

binding radio button to database to insert value ASP.NET/C#

Asked by edi77 in Programming for ASP.NET, .NET Framework 2.x, Microsoft Visual C#.Net

Im trying to learn how i can create a webform using C#/ASP.NET that binds to a sqlsever db. My code example works for textboxes. Now i want to learn to move to radio buttons because thats what most of my form will have in it. i cant seem to find a good example that shows how to do this. im using the RadioButtonList server control. i've put this (below) in my aspx file and I am sending the code behind .cs file as an attechement. I put stars on the line I want to know the syntax for. Also if anyone knows any tutorials that show more about this topic please let me know.
   <asp:Label ID="lblColor" runat="server" Text="What is your Favorite Color?" Width="220px"></asp:Label><br />
        <asp:RadioButtonList ID="rbFaveColor" runat="server">
        <asp:ListItem> Green</asp:ListItem>
         <asp:ListItem>Blue</asp:ListItem>
        </asp:RadioButtonList><br />
        &nbsp;<br />
