        private void IndustryQueryHyperlink_Click(object sender,RoutedEventArgs e)
        {

        }
    }
}

3，在domainservice中添加方法支持

public IQueryable<T_Bas_EnterList> GetT_Bas_EnterListByCategory(string category) { return this.ObjectContext.T_Bas_EnterList .Where(e => e.code_Trade.Equals(category)) .Take(5); }
