So I previously found this post How to check multiple conditions in rdlc expression which had this code inside:
Public Function GetGender(ByVal val as String) As String
Dim retVal as String = ""
If(val = "1")
retVal = "Male"
Else If (val = "2")
retVal = "???"
Else If (val = "3")
retVal = "???"
Else
retVal = "???"
End If
Return retVal
End Function
This code works, but instead of (val="1") I need something like (val = "th*") that it searches and replaces anything that contains th, for example
