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">
</telerik:RadComboBox>


Private Sub ClearRCB_LUUserName()
 
    rcb_Users.ClearSelection()
    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:

ASPX
<div>
      <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">
      </telerik:RadComboBox>
      <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">
      </telerik:RadButton>
  </div>

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

    Protected Sub ClearRCB_LUUserName()
 
        rcb_Users.ClearSelection()
        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,
