RadListBox not transferring in Firefox

[Gerardo]

Hi.

I'm using RadListbox with ItemTemplate property just as the sample in this link http://demos.telerik.com/aspnet-ajax/listbox/examples/functionality/templates/defaultcs.aspx

Everything is working fine in IE but I have a problem in Firefox. If I pass my mouse over an item, it does not do something. So if I just leave the code like this:

<telerik:RadListBox ID="RadListBox1" runat="server" AutoPostBackOnTransfer="true" Height="200px" Width="215px"
                    SelectionMode="Multiple" DataValueField="IdTarjeta" Localization-ToLeft="Quitar forma de pago"
                    Localization-ToRight="Agregar forma de pago" AllowTransfer="true"
                    TransferToID="RadListBox2">

and if I check Firefox javascript console: It shows that Sys.InvalidOperationException:Could not find dnn_ctr405_wuc_Pagos_RadListBox2

If I delete AllowTransefer and TransferToID properties, it displays the mouseover effect.

Telerik version I am using is 2010.2.713.35

Thank you and I hope to hear back from you soon.

Regards,
Gerardo

Hi.

I forgot to tell you that I am showing and hiding a Panel (ASP Control) so when I click a button, it shows me a panel where both RaListboxes are.

Hello Gerardo,

This is interesting. Do you use Ajax when loading the panel? If so, does the issue go away if you disable Ajax? Also, could you please verify that the rendered ID of the second RadListBox is dnn_ctr405_wuc_Pagos_RadListBox2. Is this the case? You can easy check whether this is true or not using a tool like firebug.

All the best,

Hi Genady.

I disabled Ajax and it seems to be working fine. Is there a way to use Ajax to avoid screen refreshing?

I have programmed a custom wizard so I have different panels that I hide or show depending on the step you are working with.

At this momment when I am working with those RadListBoxes, the screen refreshes itself when I click a transfer button. Is there a way to avoid this behaviour?

Also I checked the page using Firebug and the RadListBox Id remains the same whether it is showing Sys.InvalidOperationException:Could not find dnn_ctr405_wuc_Pagos_RadListBox2 message or not.

Regards,
Gerardo

Hello Gerardo,

Do you use RadAjaxManager or RadAjaxPanel for Ajax? If RadAjaxManager, please try removing the Ajax setting for the ASP.NET panel and instead wrap it inside RadAjaxPanel. If the issue still persist please paste your aspx code here so that we can take a look.
