Why Does My WinForms Listbox Show \"System.Data.DataRowView\" Instead of My Data?

Troubleshooting DataRowView Appearances in WinForms Listboxes

Encountering "System.Data.DataRowView" in a WinForms listbox instead of desired values can be a perplexing issue. This issue occurs commonly, despite setting the DisplayMember and ValueMembers.

The provided code accurately selects and displays data from a database into a listbox. To access the selected item value of any column, you can use the following approach:

<code class="c#">DataRowView drv = (DataRowView)lstNames.SelectedItem;
String valueOfItem = drv["NameAndScore"].ToString();</code>

This method provides access to the DataRowView, which allows you to retrieve other column values if necessary. Instead of relying on the DisplayMember property, it retrieves the raw data, ensuring accurate and usable values. By understanding this approach, you can overcome the challenge of "System.Data.DataRowView" appearances in your WinForms listboxes and work effectively with your data.
