    I have a combo box that is set to AllowCustomText = "True", however, I just cant seem to get it to clear. Here is my code:

    <telerik:RadComboBox ID="rcb_Users" Runat="server" AutoPostBack="True"
        DataSourceID="sds_UserList" DataTextField="UserName"  AllowCustomText = "True"
        DataValueField="UserName" EmptyMessage="Select User" Height="150px"
        Skin="WebBlue" EnableAutomaticLoadOnDemand="True" EnableVirtualScrolling="True"
        ItemsPerRequest="100" ShowMoreResultsBox="True" OnClientKeyPressing="HandleKeyPressUN">

    Private Sub ClearRCB_LUUserName()
        rcb_Users.Text = String.Empty
    End Sub

    Any help much appreciated.

    Hi Allan,

    I have performed some tests based on the provided snippet of code, but could not replicate the experienced issue.
    The code below works at our side:

          <telerik:RadComboBox ID="rcb_Users" runat="server" AutoPostBack="True" DataSourceID="sds_UserList"
              DataTextField="VehicleName" AllowCustomText="True" DataValueField="ID" EmptyMessage="Select Vehicle"
              Height="150px" Skin="WebBlue" EnableAutomaticLoadOnDemand="True" EnableVirtualScrolling="True"
              ItemsPerRequest="100" ShowMoreResultsBox="True" _OnClientKeyPressing="HandleKeyPressUN">
          <asp:SqlDataSource ID="sds_UserList" runat="server" ConnectionString="<%$ ConnectionStrings:TelerikConnectionString %>"
              SelectCommand="SELECT [ID], [VehicleName] FROM [Vehicles]"></asp:SqlDataSource>
          <telerik:RadButton runat="server" ID="button" OnClick="ClearRCB_LUUserName" Text="Click Me">

    Code Behind:
    Partial Class _Default
        Inherits System.Web.UI.Page

        Protected Sub ClearRCB_LUUserName()
            rcb_Users.Text = String.Empty
        End Sub
    End Class

    Does it work at your side? If yes - could you please modify it so we can see the problem locally?

    Kind regards,
