Checking the checkbox previewmouseup event should not fire

Question

clicking anywhere on the dataGrid row, the checkbox need to be checked & corresponding checkbox trigger action is performed. If am clicking on anywhere on the dataGrid row, checkbox is checking but i have placed the Checkbox in 1st column problem is when i try to check the checkbox then two events are calling checkbox checked/unchecked and mouseup event is also firing. In this scenario the Mouseup should not get fired.
