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!

Infragistics UltraGrid - How to dynamically change valuelist content in different columns

Asked by ccravenbartle in Infragistics, Microsoft Visual Basic.Net

I am using an Infragistics UltraWinGrid control in a VB.Net application to display country data using columns with a style of ColumnStyle.DropDownValidate.

The 'Continent' column contains a Valuelist consisting of 'Africa, America, Asia, Europe, Australasia'.  The 'Country' column needs to have a Valuelist generated depending on the Continent selection.  For example, if Europe is selected then the Countries Valuelist should be populated with 'Belgium France, Germany, Italy etc.', if Africa gets selected then the Countries Valuelist should be populated with 'Algeria, Liberia, Libya, Morocco, Nigeria etc'.  

I am using the AfterCellListCloseUp event on the Continent column to generate the countries valuelist depending on the continent selection but I find that this is interfering with the entries in previous rows -  numbers are now being displayed instead of the country names presumably because the new valuelist is being referenced by all rows in the column and matching entries cannot be found.
