Re: Control Properties of Type System.Drawing.Color

[James Hahn]

That looks like proper Property set code to me. What is the line of code
that the designer is generating in the Sub InitializeCompo nent for a color
that you select in the Properties Settings?

Actually, it is a custom control that inherits System.Web.UI.C ontrol. My
code for the BackgroundColor property is:
>
Public WriteOnly Property BackgroundColor () As System.Drawing. Color
Set(ByVal value As System.Drawing. Color)
Me._backgroundc olor = value
End Set
End Property
>
Me._backgroundc olor is declared as:
>
Private _backgroundcolo r As System.Drawing. Color
>
I know that my syntax for the property declaration is correct, I have used
it many times in other classes for other types (such as String, Integer,
etc.), just never with System.Drawing. Color. Any ideas? Thanks.

Re: Control Properties of Type System.Drawing. Color

I don't think I understood any of what you just said. What is
InitializeCompo nent? It is not listed in the events for the control. I don't
know a whole lot about developing desktop applications, but is it something
specific to them (keep in mind that I am inheriting from
System.Web.UI.C ontrol, which is used on web forms, not windows forms)? If
you could please clarify what you just said, it might help. Thanks.

Re: Control Properties of Type System.Drawing. Color

When you create objects using designer the system automatically creates the
code required to instantiate the object and set its properties according to
your properties settings selections in designer. The code for setting the
properties occurs in the InitializeCompo nent sub. To see the code:

Expand the Windows Form Designer generated code region
Find the InitializeCompo nent sub
Find the initializing code for your control
Find the line that sets the relevant property, eg
Me.<controlname >.BackgroundCol or = System.Drawing. Color.Green

Re: Control Properties of Type System.Drawing. Color

There is no Windows Form Designer in my case because this is now a
Windows/Desktop Application. I am writing a custom web control by inheriting
from System.Web.UI.C ontrol. Am I still misunderstandin g, or am I just not
allowed to have a property in the Property Grid that is of type
System.Drawing. Color? Thanks.

Re: Control Properties of Type System.Drawing. Color

What did it used to be before it became a Windows/Desktop application? That
may be part of the problem - when a project type is changed the default code
that the designer relies on may not match what it expects to see, and could
create problems when the designer goes to write the designer file. It might
be simplest to recreate the application using the correct project type and
copy the code across.

Sorry, there was a typo in my previous posting. I meant to say:

"There is no Windows Form Designer in my case because this is not a
Windows/Desktop Application."
not
"There is no Windows Form Designer in my case because this is now a
Windows/Desktop Application."

Sorry for the misunderstandin g, it's amazing how much difference in meaning
one letter can make, even in human languages.

Re: Control Properties of Type System.Drawing. Color

OK, but unfortunately I have insufficient experience with custom web
controls to offer much advice. I would have thought that if the property
grid can see it as type System.Drawing. Color, which it must be to give you
the enumerated list, then the designer should be able to handle it, whatever
it's trying to do.

Here's a site that might be helpful in tracking down what's happening:

There's also an interesting tip here, right at the bottom:
