Displaying Data in Comboboxes (C#)

[jw1986]

Hi,

I'd like to be able to populate data into a textbox by choosing an item in a combobox using C#. I've managed to do this to an extent - the from the database appear in the combobox but I cannot get the textbox to populate. Basically, when you select the CompanyName from the combobox the CompanyID should be shown in the textbox. Below is the code I have and the error I'm getting:

 
namespace STLSystem
{
    public partial class Client : Form
    {
        private DataSet myDataSet;
        private string connectionString;
 
        public Client(DataSet myDataSet, string connectionString)
        {
            InitializeComponent();
            this.myDataSet = myDataSet;
            this.connectionString = connectionString;
            myDataSet = new DataSet();
            this.BindComboBox(myDataSet, connectionString);
 
        }
 
        private void BindComboBox(DataSet myDataSet, string connectionString)
        {
            OleDbConnection myConnection = new OleDbConnection(connectionString);
            OleDbDataAdapter myDataAdapter = new OleDbDataAdapter("SELECT * FROM Company", myConnection);
            myDataAdapter.TableMappings.Add("Table", "Company");
            myDataAdapter.Fill(myDataSet);
 
            this.dviewmanager = myDataSet.DefaultViewManager;
            DataTable myDataTable = myDataSet.Tables[0];
            //bind it with comboBox1
            comboBox1.DataSource = myDataTable;
 
            comboBox1.DisplayMember = "CompanyName";
            this.textBox5.DataBindings.Add("Text", this.dviewmanager, "Company.CompanyID");
            //set the display index for first item to be displayed
            comboBox1.SelectedIndex = 0;
        }
 
 

Error 1 'STLSystem.Client' does not contain a definition for 'dviewmanager' and no extension method 'dviewmanager' accepting a first argument of type 'STLSystem.Client' could be found (are you missing a using directive or an assembly reference?)

Any help would be greatly appreciated.

Thanks
