Please look at the following code:

C#

comboBox1.DropDownStyle = ComboBoxStyle.DropDown;
     comboBox1.AutoCompleteMode = AutoCompleteMode.None;
     comboBox1.AutoCompleteSource = System.Windows.Forms.AutoCompleteSource.ListItems;
     comboBox1.DisplayMember = comboBox1.ValueMember = "Note";
     var myConn = new SqlConnection("...");
     var sqlStr = "SELECT Note FROM ...";
     var dAdapter = new SqlDataAdapter(sqlStr, myConn);
     DataTable dTable = new DataTable();
     dAdapter.Fill(dTable);
     dAdapter.Dispose();
     comboBox1.DataSource = dTable;

comboBox1 shows the result correctly but the Items filled with this string "{System.Data.DataRowView}" so i can't use them programmaticly.
Thanks for your help.

comboBox1.DropDownStyle = ComboBoxStyle.DropDown;
       SqlConnection conn = new SqlConnection(@"server=.\sqlexpress;database=test;Integrated Security=True");
       //conn.Open();
       comboBox1.AutoCompleteMode = AutoCompleteMode.None;
       comboBox1.AutoCompleteSource = System.Windows.Forms.AutoCompleteSource.ListItems;
       comboBox1.DisplayMember = comboBox1.ValueMember = "Note";

       DataTable t = new DataTable();
       SqlDataAdapter dap = new SqlDataAdapter("select note from notes",conn);
       dap.Fill(t);
       dap.Dispose();
       comboBox1.DataSource = t;

There's no problem in your code actually when you will not set

comboBox1.DisplayMember

property you will see

System.Data.DataRowView

But you have set those .So there is no problem in your code.Build Again and run.Hope it should work fine

Solution 2

I cast the item and get the correct result:

Quote:
var s = (comboBox1.Items[i] as DataRowView)[0];
