We present a measurement of $CP$-violating asymmetries in fully reconstructed ${B}^{0}\ensuremath{\rightarrow}{D}^{(*)\ifmmode\pm\else\textpm\fi{}}{\ensuremath{\pi}}^{\ensuremath{\mp}}$ decays in approximately $88\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $\ensuremath{\Upsilon}(4S)\ensuremath{\rightarrow}B\overline{B}$ decays collected with the BABAR detector at the PEP-II asymmetric-energy $B$ factory at SLAC. From a time-dependent maximum-likelihood fit we obtain the following for the $CP$-violating parameters: $a=\ensuremath{-}0.022\ifmmode\pm\else\textpm\fi{}0.038\text{ }(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}0.020\text{ }(\mathrm{syst})$, ${a}^{*}=\ensuremath{-}0.068\ifmmode\pm\else\textpm\fi{}0.038\text{ }(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}0.020\text{ }(\mathrm{syst})$, ${c}_{\mathrm{lep}}=+0.025\ifmmode\pm\else\textpm\fi{}0.068\text{ …
