  Dear Telerik Support
  
  I need to Fire the event SelectedIndexChanged on my RadComboBox only if the user selects something on the list, rather than typing something on it. Is it possible? If you need more information, please let me know.

  Hi Alexandre,
  
  In general when having the following properties set to the RadCombobox control the SelectedIndexChanged event fires only when an item is selected:
  

  <asp:Label ID="Label1" runat="server" Text="lbl1"></asp:Label>

      <telerik:RadComboBox ID="RadComboBox2" runat="server" AutoPostBack="True" AllowCustomText="True" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged">

          <Items>

              <telerik:RadComboBoxItem Text="test 1" />

              <telerik:RadComboBoxItem Text="test 2" />

              <telerik:RadComboBoxItem Text="test 3" />

          </Items>

      </telerik:RadComboBox>

  
  code behind:
  

  protected void RadComboBox1_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)

      {

          Label1.Text = "You selected " + e.Text + " item";

      }
