Why I get “System.Data.DataRowView” instead of real values in my Listbox?

Question

I\'m hoping someone can help. But whenever I run my code and try to view a highscore all I get back in my listbox is System.Data.DataRowView.

Answer 1

If you want your list box to show values from an specific column of the data source use lstNames.DataTextField = "SpecialColumnName";

Answer 2

I had the similar problem of picking a single value from a populated Listbox and getting System.Data.DataRowView. I was able to solve it by casting the selected item to System.Data.DataRowView and then accessing the Row and ItemArray subclasses:

var si = ListBox1.SelectedItem; 
string val = ((System.Data.DataRowView)si).Row.ItemArray[0].ToString();

Answer 3

Like I said in the comments, please add lstNames.DataBind() to your code.

MySqlConnection myConn = new MySqlConnection(connStr);

string sqlStr = "SELECT CONCAT(Name, ' ', Score) as NameAndScore " + 
                "FROM highscore ORDER BY Score DESC";

MySqlDataAdapter dAdapter = new MySqlDataAdapter(sqlStr, myConn);
DataTable dTable = new DataTable();
dAdapter.Fill(dTable);
dAdapter.Dispose();
lstNames.DisplayMember = "NameAndScore";
lstNames.ValueMember = "NameAndScore";
lstNames.DataSource = dTable;

EDIT:

Can you try this instead:

MySqlConnection myConn = new MySqlConnection(connStr);

    string sqlStr = "SELECT CONCAT(Name, ' ', Score) as NameAndScore " + 
                    "FROM highscore ORDER BY Score DESC";

  myConn .Open();

  SqlCommand cmd = new SqlCommand(sqlStr, SQLConnection1);


      SqlDataReader rd = cmd.ExecuteReader();
      while (rd.Read())
      {
        lstNames.Items.Add(rd[0]);
      }
      rd.Close();
      rd.Dispose();
      myConn.Close();

Answer 4

The following code should work:

DataSet dSet = new DataSet();
dAdapter.Fill(dSet);

lstNames.DisplayMember = "NameAndScore";
lstNames.ValueMember = "NameAndScore";
lstNames.DataSource = dSet.Tables[0];

If it does not work, please update your question and provide us with some information about the columns and values that are actually returned in dSet.Tables[0].

Answer 5

just make sure you are typing the name of field same as in datasource in other word it is a case sensitive

so : Me.GridLookUpEdit1.Properties.DisplayMember = "cur_code" is different than Me.GridLookUpEdit1.Properties.DisplayMember = "CUR_code"

Answer 6

Set your lstNames.DisplayMember and lstNames.ValueMember fields.

Gets or sets the property to display for this ListControl.

---

Gets or sets the path of the property to use as the actual value for the items in the ListControl.

This should solve your problem..
