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!

HTML table is duplicating itself at the bottom of my page, and causing strange errors.

Asked by ohmErnie in Programming for ASP.NET, Hypertext Markup Language (HTML), Visual Studio

I haven't seen this happen before. My first issues is when the app loads I have a table that has two textboxes and a button that is getting placed all the way on the left, when there should be some space in front of it. This can be seen in the step 1 image. When I go ahead and select my value from the list, the table has now duplicated itself underneath my grid, but the original table now has the correct position. This can be seen in step 2. I can get rid of the duplicate table by entering data into it and posting back, but the validation requires the original textbox to have a value as well. This can be seen in step 3. Once i make the postback, the duplicate goes away, but both values get placed in the original textbox and a comma is added in there as well. Also the grid and table are now too far left as the table originally was. This can be seen in step 4.

In addition, anytime I postback with my grid, a comma is appended in each box in my table, whether a value exists or not. What is going on here?

I have posted my aspx code, but left out the gridview to save space. Start Free Trial
