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!

ComboBox (DropDown style) Populating with displayed values?

Asked by gripe in C# Programming Language

Tags:

I've recently started trying to learn windows forms and C# at the same time. I've found myself in a rut where i just seem to be blanking out while i'm searching the documentation and have probably gone down a rabbit hole on a very simple problem.

I'm trying to create a combobox (DropDown style) and populate it with items. My understanding is that if you want the ComboBox to have both displayed items and values that are different, you have to create an object to represent this and pass that into the Items.Add method. Also, based what I've read in the docs, if you just pass a string object the ComboBox will use the same string for the DisplayMember and the ValueMember. So I'm doing this:

string string_value = "Foo";
comboBox1.Items.Add(string_value);

When I execute the application and look at the combobox i can expand it but it only contains blank entries for each item that i have added. However, if I select one of the blank lines, the expected 'Foo' string will show up in the textbox.

I have also tried writing an object with the DisplayMember/ValueMember properties, instantiating the object, setting these two properties and passing that to Items.Add but this results in the same behaviour.

Am I doing something wrong? Could someone post a complete example of populating a dropdown combobox with an arbitrary string/value pair?Start Free Trial
