How to append th, st, nd and rd for dates of the day in rdlc report?

I'm working with certifications and I need to append date of the day suffixes. I tried using =Day(Fields!Date.value) in the expression property of the TextBox but the output is just a number/date of the day but has no suffix. I have no problem in Month and Year only the suffixes in the date of the day. Thanks

Using the suggestion in Is there an easy way to create ordinals in C#? you can create a Custom Code for your rdlc report and use it with the expression.

1. In the rdlc properties add the following function in Code tab

   Public Shared Function AddOrdinal(num As Integer) As String
       If num <= 0 Then
           Return num.ToString()
       End If
       Select Case num Mod 100
           Case 11, 12, 13
               Return num & "th"
       End Select
       Select Case num Mod 10
           Case 1
               Return num & "st"
           Case 2
               Return num & "nd"
           Case 3
               Return num & "rd"
           Case Else
               Return num & "th"
       End Select
   End Function
   

2. Then modify your Expression as follows

   =Code.AddOrdinal(Day(Fields!Date.value))
