Properties of X(3872) are studied by regarding it as a DD^* hadronic molecule with J^<PC>=2^<-+> in the phenomenological Lagrangian approach. We find that our model with about 98% isospin zero component explains the existing data nicely, for example, the ratio Β(X(3872)→J/ψπ^+π^-π^0)/Β(X(3872)→J/ψπ^+π^-). We predict the partial widths of the radiative decays of X(3872)→γJ/ψ, γψ(2S) and the strong decays of X(3872)→J/ψπ^+π^-, J/ψπ^+π^-π^0 as well as X(3872)→χ_<cJ>π^0. Our analysis shows that the measurement of the ratio Β(X(3872)→χ_<c0>π^0)/Β(X(3872)→χ<c1>π^0) may signal the nature of X(3872).
