Datakeyvalue from client side

[Tina]

I am hiding a column in treelist by setting its display as false.Is that possible to get the column value in itemclick event from client side?

Hi,

One suggestion is to set ClientDataKeyNames and retrieve the value using following javascript.
JS:

function OnItemClick(sender, args) {
      alert( args.get_item().get_dataKeyValue("ID"));
   }

Thanks,
Shinu
