Hi,
Is it possible to transfer templated item between ListBoxes using the built in AllowTransfer feature..? I have tried using client side and also with AutoPostBackOnTransfer="true".
I am using version 2010.3.1109.40 of Telerik.Web.UI.dll
If it's possible to do entirely client side (without postback) that would be best, however I really just need it to work, so if it has to be done server side then that is fine.
Kind regards,
Jack

Hi Shinu,
Thank you for your response. I had seen that thread already and took some tips from it but unfortunately it doesn't match my situation exactly. The OP in that thread only needed two values in his template, which can be handled by binding to the DataTextField and DataValueField of the ListBox, as pointed out by the answerer. In my situation I need 4 values in the left ListBox and 3 values in the right. It doesn't work the same way. I have created a support ticket with Telerik to see if they can come up with a solution.
Thanks again for your help.
Cheers,
Jack

Hello David,
Since you are facing the issue that the values in the item template are more than two, so text and value are not enough, you should bind the rest values to a custom attributes. This is essential since when you transfer a particular item, you should also transfer the values from its template. So if these values are not bind to the lsitbox item, they will be lost. In your case you could easily bind

In your case you could easily bind
RoleName as Text property and the rest as custom attributes. Then when you transfer this item you should subscribe to OnTransferred event and bind the item in the second listbox by explicitly invoking DataBind method.Greetings,
