Question

How can have a combobox which has all values from a specific column in database. I have a column named StudentName and I want to have a combobox that has all values of StudentName in it.

sql = new SqlConnection(@"Data Source=PC-PC\PC;Initial Catalog=Anbar;Integrated Security=True");
adapter = new SqlDataAdapter("select * from School", sql);

How should I continue? Please give some codes for continuing these codes any help will be appreciated.

Answer 1

sqlCon = new SqlConnection(@"Data Source=PC-PC\PC;Initial Catalog=Anbar;Integrated Security=True");
  SqlDataAdapter da = new SqlDataAdapter("Select StudentName from School", sqlCon);
        DataTable dt = new DataTable();
        da.Fill(dt);
        yourComboBox.DataSource = dt;
        yourComboBox.DisplayMember = "StudentName";
        yourComboBox.ValueMember = "StudentName";
