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!

Error from gridview on Update Statement in Asp.net

Asked by BofADev in Programming for ASP.NET

Tags: gridview

What seems to be an easy task of updating fields in a sql table from a gridview has become a nightmare.   I am using asp.net.  I have a gridview on a page that allows the user to Edit records.  On update, I have two web methods where one appends a change record to a table and the other updates the original record in the table.   Both are working fine and I can see the new record in table 1 and the changed fields in Table 2 based on the new values of my gridview.   All works fine until my code exits gridview1_rowupdating  and I am returned an error.  I have searched online for this error and to no avail have found anything useful.   Can someone review my code and possibly point out what I am doing wrong?  I originally was thinking it was sql that was returning the error, but both my statements are working.  Code is posted below.  The Error I am receiving is:  Incorrect syntax near 'True'  
Exception Details: System.Data.SqlClient.SqlException: Incorrect syntax near 'True'.
