Can't get default values working!

Jason Butera

I want to have default values for my server control properties, but I
can't seem to get them to work. My typical property set is like this:

Dim m_Maximumvalue As Integer = 999999999
<defaultvalue(999999999)> Public Property MaximumValue As Integer
Get
Return m_Maximumvalue
End Get
Set(ByVal Value As Integer)
m_Maximumvalue = Value
End Set
End Property

Unfortunately, this isn't working...why not?

Also, how do you set the defaults for date datatypes, the following
doesn't work?
Dim m_Maximumvalue As Date = "12/31/9999"
<defaultvalue("12/31/9999"))> Public Property MaximumValue As Date
Get
Return m_Maximumvalue
End Get
Set(ByVal Value As Date)
m_Maximumvalue = Value
End Set
End Property
????????

Are your default values same as the initial value of your property (probably
being initialized in your constructor) ?

For datetime do this ...

C# -> [DefaultValue(typeof(DateTime),"12/31/9998")]

HTH,

Hi Jason,

The DefaultValue attribute is not meant to set the initial value of your
property, you should do so in for example, the class constructor.

Can you give me an example of how I'd do that? Thanks.
