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!

Validation of textbox entries and how to disable "Tabbing"

Asked by dmasini in Active Server Pages (ASP)

Tags: ,

Experts,

Newbie here so I will try to explain the issue as well as possible.  So I have this page where (thanks to the_bachelor) that we pass params for a record number which I will eventually send out as an HTML-formatted e-mail vias aspNetMail (nice product by the way!).

Now I want make sure that I get the following:

1) In TextBox1 I want a valid e-mail (for now only has to be formatted properly...name@domain.TLD)
2) In TextBox2 I want a valid qty they want to order
3) In TextBox3 I want a valid date they need the product

Just FYI...I know how to apply "RequiredFieldValidators", "RegularExpressionValidators" and "RangeValidators" and "ValidatorCalloutExtenders" etc.

The problem is when I run my page I am able to just "TAB" through the fields even though I "SetFocusOnError".  I want to ALWAYS force the cursor back to the focused texbox if it DOES not validate properly.

Any ideas/thoughts would be appreciated!  Code Snippet included for your review.

Thanks again,

DM
