We report a measurement of the exclusive e{sup +}e{sup -}{yields}D{sup (*){+-}}D*{sup {+-}} cross section as a function of center-of-mass energy near the D{sup (*)}{+-}D*{sup {+-}} threshold with initial-state radiation. A partial reconstruction technique is used to increase the efficiency and to suppress background. The analysis is based on a data sample collected with the Belle detector with an integrated luminosity of 547.8 fb{sup -1}.
