Date is not sorted in reporting services consecutively and correctly I am trying to generate a report using the SSRS,but the date is not being sorted 

as I want when running the query.

It is being shown as follow (consecutive months are mixed):

28/05/2014

28/06/2014

29/05/2014

29/06/2014

What I need is to have it as follow (all consecutive days in the same month) :

28/05/2014

29/05/2014

28/06/2014

29/06/2014

Note that I am using this expression to convert the date : 

convert(nvarchar(50),dbo.mytable.manufacturyDate,103)
My default value was a datetime and converting it to text was the problem when 

sorting.So I removed the convert in my expression and make sure in the 

manufacturyDate text properties that it is a dd/MM/yyyy
