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!

Binding to Custom Properties

Asked by Erick37 in Microsoft Visual Basic.Net

Tags: ,

Hello binding experts!

I would like to bind a custom property of a UserControl to a typed DataSet.

My scenario:
On the form there is a DataGridView control
Its DataSource is pointing to a BindingSource
The BindingSource is pointing to a Typed DataSet

My UserControl has a property also bound to the DataSet through the BindingSource.

So far this works great.  When I navigate the rows in the grid, the UserControl gets (or sets) the column value for the row.

Now for the problem:
When navigating the rows, the dataset is being marked as changed for the rows I select, even if I make no changes to the data.

When I do a similar binding with a TextBox or DateTimePicker it does not update the dataset when navigating.  It's only when I bind to my custom property that it marks the dataset row as being changed.

How do I fix this so I can navigate without actually modifying the dataset?
