The convergence of Ces\`{a}ro means of negative order of double trigonometricFourier series of functions of bounded partial $\Lambda$-variation isinvestigated. The sufficient and neccessary conditions on the sequence $\Lambda=\{\lambda_{n}\}$ are found for the convergence of Ces\`{a}ro means of Fourierseries of functions of bounded partial $\Lambda$-variation.
