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!

Composite control with design-time support

Asked by knowlton in Programming for ASP.NET

I think I may have reached a point in my development needs where I need greater control, flexibility and power than an .ascx can provide.

But I need a good guide to help me make the transition.  What I need are some good resources for getting my head around custom composite controls with design-time support.

I want to group a bunch of controls and html elements together as a single unit plus have design-time support, such that I can position those elements within the custom control itself.

How can I do this?  I welcome websites and book recommendations and any advice you can give.

//MY COMPLAINT IS THAT THE TEXT BOXES IN THIS SAMPLE (gotton off of MSDN) DO NOT SHOW-UP WHEN I DROP THE CONTROL ONTO A WEB PAGE.  I WANT THEM TO BE VISIBLE AT DESIGN-TIME AND WHEN I CLICK ON THEM I WANT TO SEE THEIR PROPERTIES IN THE PROPERTIES WINDOW.
