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!

Newbie: Simple Databinding in WinForms

Asked by softwarea in Microsoft Visual C#.Net, .Net Editors & IDEs, Visual Studio

Tags: ,

Hi experts,

I have a small WinForms application that contains
- a DataGridView,
- a BindingNavigator,
- a BindingSource and
- a Textbox

The DataGridView shows commodities coming from a database and the BindingNavigator helps the user scrolling through the rows of commodities. DataGridView and BindingNavigator are connected to the same BindingSource. Everything works as expected.

However: I want the TextBox to show a certain value (i.e. the commodity's name) of the currently focused row in the DataGridView.

Thus I set a databinding in the Forms Load()-event like this:
            TextBox.DataBindings.Add("Text", commodityDataSource, "CommodityName");

When I start the application, the TextBox shows data from the first DataGridView row as expected.

But here is my problem: When I select another row in the DataGridView via Mouse or via Navigator the content of the TextBox is NOT updated.

What am I missing? Thanks for any help!
