DefaultValue in control library

[rustyd]

I am building a control library. I have a text box, radio button, checkbox, and a usercontrol. I added 7 properties to the text box class. Here is an example of a string DefaultValue attribute I tried adding:

 

<DefaultValue(GetType(String), "C"), _

Description("RICS Data Type (C=Char, N=Numeric)")> _

Public Property RICSType() As Char

Get

Return _RICSType

End Get

 

Set(ByVal Value As Char)

_RICSType = Value

End Set

End Property

 

In a different solution, I have the text box from the class on the toolbox. I drop a new, inherited text box onto a form, but the default value for string properties is null character. Here is the code:

 

Friend WithEvents TextBox1 As RICSLIB.Ritext

...

Me.TextBox1 = New RICSLIB.Ritext()

...

Me.TextBox1.RICSType = Microsoft.VisualBasic.ChrW(0)

Are you saying that the defaultvalue attribute you applied isn't working? I usually just use the constructor overload that accepts only a string but from looking at yours it should work - the default value in the propertygrid should be "C".

 

You realise that attribute applies only to the propertygrid I take it? You still have to initialize the variable either in your constructor or on the declaration before the behaviour will be as you would expect.

Thanks, divil. I did not have them initialized in the constructor.
