Question

I have a c# windows form that pulls a generic list on load using a thread worker. This populates a drop down of client numbers.

private void ZurichAccountTrades_Load(object sender, EventArgs e)
{
   tbLocation.Text = @"C:\Reports\Output\";
   lbGettingData.Visible = true;
   CheckForIllegalCrossThreadCalls = false;
   var thdWorker = new Thread(PopulateDropDownPersonNumbers);
   thdWorker.Start();
}

private void PopulateDropDownPersonNumbers()
{
        ddProviderNo.Enabled = false;

  progressBar1.Increment(10);

  //Get data somehow here....

  foreach (var person in providerPNos)
  {
    ddProviderNo.Items.Add(person.PersonNo);
    progressBar1.Increment(1);
  }
  progressBar1.Increment(100);
  lbGettingData.Visible = false;
  ddProviderNo.Enabled = true;
  progressBar1.Value = 0;
}

private void ddProviderNo_SelectedIndexChanged(object sender, EventArgs e)
{
 //What do I do here??
}

What I want is when a user selects a client number the client name (which is held in the same list) is displayed automatically.

How can this be done?

Answer 1

Add object Person instead of PersonNo

  ddProviderNo.Items.Add(person);

Then:

private void ddProviderNo_SelectedIndexChanged(object sender, EventArgs e)
{
    ComboBox comboBox = sender as ComboBox;
    textBox.Text = (comboBox.SelectedItem as Person).Name;
}
