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!

Insert/Edit/Delete from Dataset, linked to DataGridView

Asked by allanmark in Microsoft Visual C#.Net, Visual Studio

Tags: , ,

Greetings all

I have a dataset that populates a datagridview on a Windows form. Beneath the grid are a series of Textboxes that are Databound (eg. txtTitle.DataBindings.Add("Text", dsLevelDetails, "Levels.L_Title"). Thus, when the user scrolls through the DatagRidView, the correspondign details are reflected below. I want to insert, edit, delete, save.

When I click the Insert button (see snippet)  the Textboxes clear and I am able to capture data.
When I click the Save button (see snippet) the current record in the DataGridView receives the values that were captured and a blank record appears attached to the end.

Any ideas what I have done wrong?

In advance, thanks!!
