title: Binding dataSet to listbox
body: <p>I have two listbox's. One is filled by Users.</p>
  
  <pre><code>daUsers = new SqlDataAdapter("SELECT * FROM Users", connection);
  daUsers.Fill(UsersLocal);
  listBox2.DataSource = UsersLocal;
  listBox2.DisplayMember = "Name";
  listBox2.ValueMember = "ID";
  </code></pre>
  
  <p>Second is filled by documents. In document dataTable I'm storing same data wit UserID. 
  Now I want to bind second list box with data from Document DataTable where UserID is from first ListBox. How I can do that? I tried by SQLCommand but it failed. </p>
  
  <pre><code> daDocuments = new SqlDataAdapter("SELECT * FROM Documents WHERE UserID='listbox2.SelectedValue'", connection);
  </code></pre>
