Hi
Marc,
By
default dragging SymbolPaletteItem from symbol palette will undergoes serialization
and deserialization. It will take some time. This is our default behaviour. However
you can improve performance by use our virtual method CloneContent to return
any object other than serialization process by internally. This method will avoid
serialization and deserialization process by creating new object as you
desired.
We
had created sample in which we override that method to return new button
object. It will considerably increase the performance. For more information
please refer the attached sample.
Please
let us know if you require further assist on this.
Regards,
Parthiban
