Hi,
I have a objectA with a property that return an object B (accessor GET only)

CanConvertTo, CanConvertFrom, ...
The problem is that can not edit the object B (the proerty in greyed) in the
propertyGrid (I can edit these properties but not the object directly
because, it doesn't have SET accessor)
In fact, when I edit this object, I woul like to change just the...

I have created ExpandableObjectConverter in C#. for use in
System.Windows.Forms.PropertyGrid.
The property grid shows the DiffItem is a object that holds member
TheItem.
without expanding TheItem
It works if u click, select from drop down box. until you DoubleClick
it shows error:
"Invalid property Value". with "Object type cannot be converted to
target type."

I made a ExpandableObjectConverter subclass but its GetProperties method is
not called when my object is set as a Converter of PropertyDescriptor. The
thread above gives a good explanation of the problem, but...

Hello.
I have an ExpandableObjectConverter subclass that I associate to the
'Converter' of a custom property descriptor.
After I changed my .net code to the new syntax (VC 2005), the
GetProperties method of my converter class is not called anymore by
the PropertyGrid. Now my expandable properties always show a property
'Length' with value 0.

Hi,
I'm using classes with the ExpandableObjectConverter attibute in a
UserControl for properties. This works fine for some classes, and properties
of these classes can be edited during design time.
However, classes which are derived from CollectionBase don't save their
values in the form's code. Properties can be changed in the VStudio property
editor but they are not persistent:
// Property values are saved in the forms code.

Hi!
I've written a custom ExpandableObjectConverter in which I have overridden
GetPropertiesSupported and GetProperties (and some more). By setting
breakpoints in all methods I have found out that only GetProperties never
gets called, however all other methods are called correctly. (The respective
class has the TypeConverter attribute set.)
Does anyone have a clue about what this situation might cause?

via a PropertyGrid.
However, GetProperties is never called!

I have found out that all overrides are being called correctly, except for

Hi there,
Can anyone provide any insight on why MSFT introduced
"TypeConverter.GetProperties()". There are two classes for dealing with
metadata in .NET, 'Type" and "TypeDescriptor". Each has a "GetProperites()"
method so why complicate the situation even more than it already is by
adding a "GetProperties()" method to "TypeConverter". The class is supposed
to be for converting types so "GetProperties()" seems misplaced and
redundant (as...

Hello,
i am doing a custom class for my property for a property gird using
ExpandableObjectConverter.
I have a class (CustomFontClass) that uses a Converter which inherits
the ExpandableObjectConverter. everything works fine, but the only
thing that doesn't work is that the MyNewFontList NEVER calls the SET.
I have followed the http://www.codeproject.com/KB/vb/using_propertygrid.aspx
example in the example its the same case .

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
