When a button is clicked, I want to populate multiple ddl's and under
certain circumstances I want to set the SelectedValue.  I've tried different
variations of this:

protected void btnImport_Click(object sender, EventArgs e)
{
  [snip]
  int tblcols = dsCsv.Tables["csv"].Columns.Count;

  for(int i=0; i<tblcols; i++)
  {
       ListItem liItem = new ListItem();
       liItem.Text = dsCsv.Tables["csv"].Columns[i].ToString();
       liItem.Value = dsCsv.Tables["csv"].Columns[i].ToString();
       ddlAddress.Items.Add(liItem);
       ddlOrganization.Items.Add(liItem);

       if (liItem.Text.ToLower().IndexOf("company") >=0)
      {
          ddlOrganization.Items.FindByText(liItem.Text).Selected = true;
       }
    }
}

This doesn't work.  Although items were added, the code won't recognize
these items until the entire btnImport_Click is finished.  How can I
accomplish this?

Thanks.
