Paste Clipboard Text within textbox inside TDBGrid

I am trying to Paste Clipboard contents within Textboxes inside True dataBase Grid control.I am able to copy contents and paste it inside drop-down lists within same TDBGrid but I couldn't paste it within textboxes inside TDBGrid.

Is there any specific property which needs to be set inside TDBGrid ?Because I believe that this has something to do with Grid Control itself and its Data Binding.

Any Help ??
