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!

Supressing Treeview Expand and collapse events

Asked by ram2098 in Programming for ASP.NET

Tags: treeview, node, expand

I am encountering a problem when I try to supress(avoid going to server) expand and collapse events of the treeview. I have written a javascript to do so. Eventhough it works fine when i click on '+' and '-" signs, it throws an expection when i click on the node and try to execute a server side event.
for example :
suppose i have 3 nodes and 3 child nodes for each of them
-node1
   -node1.1
   -node1.2
   -node1.3
-node2
 -node2.1
 -node2.2
 -node2.3

If i add the javascript to supress the event ....and when i expand the first node and click on node1.1 it is giving me the runtime error as :
"The node at index 1.1 is not currently displayed in the tree. SelectedNodeIndex cannot be set to an undisplayed node (all parents of a selected node must be expanded). "

Please suggest
