    Hello,

    I'm using the following autocomplete radcombobxo:

    <telerik:RadComboBox
                                     ID="ParentRadComboBox" runat="server"
                                     Width="590px" Height="140px" AllowCustomText="true" MarkFirstMatch="true"
                                     EmptyMessage="Type a Title" DataValueField="SerID"
                                     DataSourceID="GuideSqlDataSource" DataTextField="Title" >
                                 <CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation>
                            </telerik:RadComboBox>

    The problem is the user can type a text which is not even exist within the radcombobox item and click Submit (A Button).
    I need to use the property AllowCustomText .
    How can I validate that the typed text is valid?

    Please, I need your help,
    It is appreciated to sendme the modified code.

    Regards,
    Bader
