Hello,

I am trying to capture when an item is transferred from the list RadListBoxSource to the listbox lbSupervisors.  I have put breakpoints on lbSupervisors_Inserted, lbSupervisors_Inserting, lbSupervisors_Transfered, lbSupervisors_Transfering and none of them are being hit when I transfer an item from RadListBoxSource to lbSupervisors.  Please tell me why these breakpoints are not being hit.

 

Thanks,

Stephen

Hello Shannon,

First of all, in order to be able to handle the transferring operation of items at server-side you need to set the AutoPostBackOnTransfer property of the Source ListBox to true.

Also, the responsible control that handles the process for such operations is the Source ListBox - the one that has specified the TransferToID property in its implementation. However, as I can see you have handled this events for the destination ListBox (Supervisors).

Please consider subscribing for the OnTransferred event of the RadListBoxSource, instead of the Supervisors ListBox along with setting the AutoPostBackOnTransfer  to true.
