[2005] Custom Component Property Default

[Aspnot]

I created a version of the standard TextBox that adds an IsValid property. When I started using this control in my project, I had IsValid initially set to False inside my component. Now, I want to have it initially set to true. I made the changes to the component and recompiled the code. Everywhere I already have this control, it still remembers this default value since it is in the .Designer file.

How do I get this to update when I make a change? Surely, I don't have to manually do this.

    <System.ComponentModel.Browsable(False)> _
    Property IsValid() As Boolean
        Get
            Return _IsValid
        End Get
        Set(ByVal value As Boolean)
            _IsValid = value
        End Set
    End Property

If you are saying that you have already dropped a control, say, on to a form and set it's properties; then, yes you'd have to go back a reset the properties of each control on the form.

Ouch. That's what I was affraid of.

Did you replace the control on the forms with the new compiled version ? When you drop the new version on your forms it should automatically regenerate new designer code and if your new control has the default as false then thats what will be set.

Remember these two things:

1. Each instance of a control that is dropped on the form becomes it's own instance of the class that created it -- once you modify it, it becomes unique.

2. Would you like it if Micorsoft suddenly changed the default backcolor of a button to black and then sent out the new dll and suddenly every project you had ever built had it's buttons turn black?
You wouldn't expect that -- so that's not how it works...Thankfully.
