How to Access Values from DataRowView in WinForms Listbox?

Accessing Values from DataRowView in WinForms Listbox

When attempting to retrieve highscore data for display in a listbox, users may encounter the error of receiving "System.Data.DataRowView" instead of actual values.

To resolve this issue, ensure that the code correctly assigns the DisplayMember property to the desired column and sets the DataSource property to the appropriate DataTable. In the provided code:

lstNames.DisplayMember = "NameAndScore";
lstNames.DataSource = dTable;

This configuration binds the listbox to the "NameAndScore" column of the DataTable. However, to access individual values within the DataRowView, you must cast the selected item as a DataRowView and retrieve the specific column value:

DataRowView drv = (DataRowView)lstNames.SelectedItem;
String valueOfItem = drv["NameAndScore"].ToString();

Using this approach, you can access the actual values from the selected item and perform further operations as needed. This solution provides flexibility in working with multiple columns and ensures that the listbox displays the desired data effectively.
