                      DataTextField="LocationText" DataValueField="LocationID" EmptyText="Search By Practice Name/Code/PostCode"
                      EnableLoadOnDemand="true" EnableVirtualScrolling="true" AutoValidate="true"  AutoPostBack="true" AllowCustomText="false" 
                      TabIndex="11"&gt;
  
                      &lt;HeaderTemplate&gt;
                          &lt;div class="header" style="width: 290px;"&gt;
                              Practice
                          &lt;/div&gt;
                          &lt;div class="header" style="margin-left: 0px; width: 90px;"&gt;
                              PostCode
                          &lt;/div&gt;
                          &lt;div class="header" style="margin-left: 0px; width: 90px;"&gt;
                              Practice Code
                          &lt;/div&gt;
                          &lt;div class="header" style="margin-left: 0px; width: 100px;"&gt;
                              PCT
                          &lt;/div&gt;
                      &lt;/HeaderTemplate&gt;
                      &lt;ItemTemplate&gt;
                          &lt;div class="item" style="width: 290px;"&gt;
                              &lt;%# Eval("LocationName")%&gt;
                          &lt;/div&gt;
                          &lt;div class="item" style="margin-left: 0px; width: 90px;"&gt;
                              &lt;%# Eval("PostCode")%&gt;
                          &lt;/div&gt;
                          &lt;div class="item" style="margin-left: 0px; width: 90px;"&gt;
                              &lt;%# Eval("PracticeCode")%&gt;
                          &lt;/div&gt;
                          &lt;div class="item" style="margin-left: 0px; width: 100px;"&gt;
                              &lt;%# Eval("PCTName")%&gt;
                          &lt;/div&gt;
                      &lt;/ItemTemplate&gt;
                  &lt;/obout:ComboBox&gt;
  
                            &lt;asp:TextBox ID="txtPractice"  runat="server" Width="250px" Height="21" Visible="false" /&gt;
  </code></pre>
  
  <p>Code behind</p>
  
  <pre><code> Private Sub ddPractice_SelectedIndexChanged(sender As Object, e As Obout.ComboBox.ComboBoxItemEventArgs) Handles ddPractice.SelectedIndexChanged
     If ddPractice.SelectedValue = "685" Then
         txtPractice.Visible = True
     End If
  End Sub
  </code></pre>
  
  <p>I also have a function that loads items to the combobox</p>
  
  <pre><code>  Private Sub Practice_LoadingItems(sender As Object, e As     Obout.ComboBox.ComboBoxLoadingItemsEventArgs) Handles ddPractice.LoadingItems
  
      Dim data As DataTable = GetPractices(e.Text, e.ItemsOffset, 10)
  
      Dim combobox As Obout.ComboBox.ComboBox = CType(sender, Obout.ComboBox.ComboBox)
      combobox.DataSource = data
      combobox.Items.Clear()
      combobox.DataBind()
  
      e.ItemsLoadedCount = e.ItemsOffset + data.Rows.Count
  
      e.ItemsCount = GetPracticesCount(e.Text)
         End Sub
  </code></pre>
