Ok, I keep running into this problem

In my aspx I am calling a simple function.

But the problem is, that the function is either, string, integer, etc.

If there's null's in the data, the function explodes because it's set to a string or integer, etc.

How can I make the function accept both a null, and another data type so that I can

write some if then's to do different things if it is null or another data type.

Here is the code to give you an idea

#
# .aspx code
#
# <%# GetRatingFormat(Container.DataItem("Rating") %>
#
#
# .vb code
#
# Function GetRatingFormat(ByVal UserRating As Decimal) As String
#
# If IsNothing(UserRating) Or IsDBNull(UserRating) Then
# Return "Not Yet Rated"
# Else
# Return Format(UserRating, "0.0") & "%"
# End If
#
#
# End Function
#
#
#
UserRating needs to accept both null and decimal

any help would be greatly appreciated

String class has the NullOrEmpty Static method use it before you update Db about the rating is made(4 Stars etc)

in C# that would be:

public String FormatRating(Decimal numRated){
return String.IsNullorEmpty(numRated.ToString())?"Not Rated Yet":numRated.ToString("0%");
}
